Lovely job Andy, don't listen to trolls in the comments banging on about legal ebikes, for over 20 years I've been involved with the worldwide ebike scene and am well known and still am riding high power ebikes, every day in London the roads are full of them and electric scooters, fact is if you are sensible, ride safely and maintain the bike you won't ever have a problem, lots of these 250w legal bikes peak at up to 800W, the police have far more urgent things to worry about than an electric bike that's producing over 250W in power. You keep stepping up your game and I love you for that and your prices in your shop are very reasonable, well done. People should try a legal Vs a real ebike before they comment, it's illegal to watch BT sport on your phone in the middle of a field without a TV licence, some laws are there to be broken 😆
Thanks mate, yep you are right in everything you say there and I really appreciate your comments, you’ve been here from the start and your channel is great too 😁 I don’t care about the self appointed ebike police, they clearly have never ridden an ebike let alone build one😂
In the next two years, I will be building an electric bike of my own, I wanted one since my mini electric motorcycle got stolen out my years when I was young. And I finally can see it becoming a reality in the next few years. With the help of your videos and my new job in the military, i feel as though I could really do it.
Absolutely brilliant build, very nice to see a frame ready to be built on that's light and of a high end spec. Only one thought, what's stopping water, mud, grit etc from running down the outside of the battery and pooling in the square section of the frame that houses the battery connector? From what I can see in the video it doesn't seem to be sealed at the bottom and I couldn't see any drainage holes apart from the hole the cables came up through for the battery and display cables? Concerned it would be problematic come winter time on the trails
I have this exact battery, and can confirm it is a problem. I use vaseline spray to try and keep it from jumping, but i am looking for a better solution
Nice bike and tutorial. I’m 61 and I just went from knowing nothing about ebikes (always had regular pedal bikes, well and also a few Harleys and Hondas) to assembling a dual 1200W (2900W Peak) Ebikeling setup, including front and rear motors. Watched a couple of your videos and had it running 55km/hr in less than a day. Next I want to try building my first mid-mount bike. I’m hooked.
Dual suspension is the way to go. I have built several bikes, and my favorite are ones with front and rear suspension. They ride smoother and tackle rough terrain much better. Nice!
I've been considering an e bike for many years. After years of looking and researching what you have built is I would say is 99% the excact bike I would have built. From the frame to the motor to the pedals. Absolute perfection. Well gel. Also what was the total cost in the end.
Thanks for sharing this wonderful video, bro! I plan to transition 90%+ of my travel to using an ebike. I love bicycles, being outside, enjoying the journey and not adding to the pollution (and noise pollution) here in the central valley of California. I can't wait to be adjusting my time schedules to enjoy going most everywhere on my bike. Keep up the good work!
Brilliant mate!! Once iv got my driving license and I'm on the road, I need to save for one of these!!! Build loads of MTB, BMX and jump bikes over the years but these look incredible! Well done to you man love everything you do! Take care bud
Hi Andy I've just rebuilt my 21-year old Marin dh B17 with the same hope disc in a 160 mm and use a zoom hydraulic caliper fon now fits perfect works very well Regards Mark
I test rode a $13,000 Specialized eMTB the other day... That is insane, it was pretty neat but not $13,000 neat. This is a fun video, thanks for putting it together.
Your builds/videos and music are top notch Andy, don’t listen to the nay sayers, ride on. I grew up building bikes from bits in the scrap as a kid and your vids inspired me to build an ebike. Parts are on route and I’m excited to get building again👌
No worries, I’m struggling to find a 27.5” Boost wheel set with/without tyres, could you pm me if you could me a set shipped? I take it the wheels on your bike are Aluminium?
A used donor bike and you could build an amazing machine for a tiny fraction of what the mainstream manufacturers are asking. As you say, even all new it's way cheaper. They have been ripping us off asking those kinds of prices. I guess a fair bit of the 8K or whatever goes to sponsor people who try to justify that you need to spend all that on a bike.
Andrew Norris it's not ripping off as they've been investing R&D into developing this tech for decades, plus the high end ebike usually have a lot of fit and finish people hours invested into them. They just seem expensive when looking at the highest end new models that are dripping with high end lightweight yet durable materials and compared to high volume gas vehicles that we are so used to that are cheap yet are expensive to operate over time
Yep Andy took you two years to get to this level of expertise well done you are the best mate. I just recently purchased a TFT C850 bafang display with a new control box ..you beat me by 6 weeks lol...but get your self a eggrider or better have both...thats my end game ..full blue tooth connectivity to the mobile phone and a clear screen for additional info. Love the new monster looks like Bafang and Bosch are going head to head it will be interesting to see who brings out the best products...nothing like a bit of good competition> That way us paupers get a better choice.One day I will make a 1 hour plus video on my fat bike. Cant wait to see the next video....and when are you going to use Higo connectors ???
I've build a few e bikes But they only cost me a fraction compared to the ones on this channel lol. For £380 every single part & bike included. I've built 3000w 72v to 84v. Mid Drive system Ebike 29 inch wleels & 12 speed set-up at the back And 3 at the front. With rotor discs & 4 piston sram hydraulic brakes. Air shock forks It's a scott racing bike converted into a motorbike. If I bought everything new plug & play parts it would have cost probably £4000+. I have no idea why UA-camrs don't build cheap Ebike just to show the viewers.
I like that the battery is not integrated into the frame. This gives you the option of bigger batteries than internal battery storage allows. Cool build
Just been looking at FullyLoaded London, their bikes are crazy prices and some don't have these quality components. I see you can buy this bike ready built. I have ridden 'normal' eBikes but never owned one. That is about to change, I love this build and it is pretty future proof. Would the experienced E-bikers think this is too powerful for a first E-bike, all be it for a long time cyclist. My thinking is for £3400 this bike gives so much more than I have seen in London. I really am thinking of buying one fully built as it does cost a lot and prefer the idea of Andy building my bike.
Great video! You should get in touch with the guys on EMBN show and let them try it out to compare it to the other bigger brands. Keep up the good work!
The trouble appears to be they are sponsored by the big brands who charge £8K for a bike. If you look at their past comparisons they have not always compared like for like.
Great vid you talked about the cost of E- bikes at the beginning been very expensive but in your video you did not mention the total cost off the build ?? Andy
Plus shipping and VAT from China, not his frames buys them from Ali express traders and makes them up and provides no customer service or warranty. Him and his baldy mate are dodgy
@@kaybeane7196 If you use Fox shocks front and rear and had to buy everything new or newish I would guess you’re looking to spend $5k or a little more. That’s my guess.
Andy- The EX1 crank arms you have are "self extracting"(ie you don't need a crank puller) the little "cap" is meant to stay in place and the 8mm hex tool goes through it- when you undo it the 8mm crank bolt inside pushes against the (10mm) "cap" and pops off the arms... and be warned the standard thread crank pullers are not quite the same thread and size as the EX1 threads.... removing the 10mm "cap" and using a standard puller you may rip out the threads....
Use my bafang converted voodoo wazoo to go to work instead of the car ( milled 10mm off the bottom bracket) .Just got a 31AHr 48V battery from Mike at GreatMax , made to order in China, delivered DHL to the door, duty paid. very happy.
Hi Andy, just came across your video and really appreciate what you’ve shown. I love trail riding and currently have a Cannondale Scalpel. I would love to keep riding to keep healthy but at 43 it is becoming increasingly more demanding. I agree with most that current emtb are way overpriced for the average Joe out there and BAFANG motors even seem to offer a superior spec than most fancy bikes on the current market! I would like to do what you’ve done (build from scratch) as a statement and for the feeling of building it with my hands. May I ask; how much in terms of parts all together have you spent to put the whole bike together??
My 36V350W TSDZ2 mid drive motor has a pretty good 80nm of torque on a carbon fibre frame on 24 Spoke Zerolite Pro Vuelta wheels which are pretty hard core wheels. My bike is set up for the road using Michelin Wild Run'R Advanced 1.1" slick tires with MR TUFFY tire liner, I've got both the 36T & 48T Chainring on the front. With the tires I'll probably get 1 puncture from the life of the tire after it's worn down to braid under the outer casing which has worn off after thousands of kilometers riding.
Yh I’ve derestricted mine mate with the speed box 2.0 way better plus it’s being customised throwing loads of new purple parts on it will look the dogs doo dars when it’s all done !🤘😆
I'm guessing this is the 17" frame, and there is also a 19"? Do the frames accept 29er wheels? Is there an advantage/disadvantage to running a 29er wheel? Would you consider an advantage of running a smaller rear and larger front like a dirt bike?
Sweet ride. Gotta love Bafang. Just finished my build. BBSHD 1500 w 52v 13mwh battery on 26" trek hard tail with new-ish fork. Then every thing else is new and as light as possible making a 46.1LB (20.95kg) death machine with a top speed of 41.6mph ( don't know in kph) because we ride on the right side of the rode here. However my next build after this one gets stolen will be with a frame and battery similar to what you started with but maybe carbon idk. Ride it like ya hate people. Later
@@gregorypatzelt6964 yes a right hand 1/2 twist throttle next to Shimano rapid fire shifters and Shimano m355 hydraulic disc brakes leavers. on the left side the color display. I was told with a half twist throttle that I could not Mount the index shifters however I had no problem and it works fine for me I even had my brakes customized with the rear brake on the left and front brake on the right coming from a motorcycle background I'm more familiar with it that way and everything was mounted on a carbon fiber handlebar. Chain line was the biggest problem but after installing a LunaCycle Eclipse chain ring its perfect. I have even been pulled over for speeding by the local sheriff department luckily no ticket.
Thanks for putting the video together It looks great... I was looking into doing my own e-bike but after watching your video very tempted to invest in your frame and build one from scratch.
I think the caples passing through holes in the frame should go through grommets to avoid chafing, especially the battery output leads. I hope the battery output is fused.
Sick ass build Man! Definitely digging the bike. Would love to learn to build my own. Your enthusiasm is contagious. Keep the vids comin brotha! bIG uP!!
Impressive. Looks really cool. You really know how to build cool e-bikes. the only thing i miss is the mud guards for the tires and something to seal the connectors, to prevent rain and moisture from comming in. Great job i really admire your work and fearless attitude and just getting the job done👍👍🐿. Looks like a really cool 👍😊
$3300 AUD for the bike frame and drive train (so would need suspension and brakes etc) or near 7k for the bike fully built. Honestly you can build something far cheaper with the same performance using local bought parts. oz-ebikes. com is a good place
Great job @AndyKirby. You achieved what some of us only dream about. I'm curious where the motor controller is hidden. It must be built into the motor is it? What mech have you got? Seems the chainwheel is very large. Yes you need to publish the weight. What are the options for brake cut-outs using Hydraulic brakes? Good luck with it. Cheers.
90% of mid-drives have built in Controllers into the motors. That's why their abit more bulker. Mid-drives are more torque because their using the chain for power performance, while hubs require the power straight off the bat in the wheel So some are direct or geared, Requiring the ESC to be outside for better cooling. But Mid-drives have so much torque their motors don't get as hot. So they can handle more load that's why their dependent on the chain for power.
@SpeedRacer 650 Oh no. I got something cheaper and nicer upgrade platform i like. I got a Hyper-Eride mountain bike with V-brakes. (Can also support disc brakes. but i'ma stick to V-brakes atm.) It's gonna be like less then 3500-4000$ once fully upgraded. Stock bike is 645$ atm, will have Dual battery packs, Dual motors (Front and Mid-or Rear hub still deciding which system to go with on the rear.), Full Shimano Deore system 9speed, Rockshock Solo air fork, Alum handlebars/Seatpost/Stem/Peddles/etc. With 3point mounted rack for cargo. It has flush mounted battery (that'll be used for ether rear or mid-drive.), Another battery above it as a waterbottle design for front, or extra batteries in rear rack. Dual throttles.
@SpeedRacer 650 Yes it's a hardtail vs a Full suspension. Roughly similar. Fun thing about building your own kind of bike tho. Is basically the only thing you really need to swipe if you want it a different bike. Is the frame. Well course in your case or so, the frame requires the specific motor and battery. But if you bought a normal frame you could use a mid-drive conversion kit and waterbottle design battery (that fits like a normal waterbottle drink holder.). This bike you could also technically upgrade to dual motors to, just get a seatpost rack, and add a pack with a battery for a front hub. And your good to go. Not much weight added, maybe 10-15pounds but since the battery will be in the rear, and the front hub. it'd still keep it pretty balanced. The weight on mine stock is 50pounds. This is pretty much roughly the exact same as you find normally on high end ebikes to around 45-60pounds is the targeted range for mountain ebikes. Roads will be probably lesser since their general design is speed, so lightweight is mainly their focus. With the rack and cargo bag with abit of stuff i'm adding 10pounds yes. And a battery 5pounds and a hub 5pounds. So extra 20pounds from the stock 50. But i'm keeping weight pretty evened across the bike. I'll have 2batteries in the middle of the frame, hub front, and ether hub rear or mid-drive middle, and if maybe extra battery or so in rear rack. But mainly rear for cargo. Overall the 20extra pounds isn't gonna be much pain including if both my drives are are good on torque and power. And i have good tread with large nobs with good psi to handle the weight and grip. I had a yukon trail cruiser that was steel frame, ran at 24volt 250watt 10ah lithium battery, stock weighed 80pounds, still hit around 15-20mph on it and 20miles of range, even after i added like 30pounds extra with more cargo weight i put on, It was a beast of a cruiser. And all on throttle control no peddling. Even off-road and it shredded pretty well. Compared to trails alot of mountainbikers go that are pretty fairly hard, Even my yukontrail shredded threw where i go, which normally has a softer kind of road. So if that could handle with such a lower motor. I'm sure the upgrades and abit lesser weight my Hyper has, Will rip much better with it's power and dual performance.
@SpeedRacer 650 Mountain biking isn't about speeding 25mph+ down hill. Mountain biking is about going off-road and exploring. People seem to mistaken what the point of mountain biking is really. It's off-road tough terrain riding. Not about zipping downhills and shredding inches from cliffs, or jumping 50feet off ledges. Any mountain bike will have it's limits to how much beat you can smash on it. If you want downhill, you want some good suspension to dampen the hips and humps of the fast attacks of the rough terrain while zipping down. With a pretty good strong frame. Rest of the components can be whatever your choice since they have no relation to the strong of the frame or suspension. If you want a Jumper. you need to have a strong frame, with stiff suspension to have a slower impact. Meaning the suspension isn't gonna be plush on off-roading, but will take the impacts much better on jumps. If you just want a overall mountain bike. Any bike normally will do. Since your main focus is to enjoy riding, Not zipping fast or jumping crazy. But riding the rough harsh terrain, which is gonna have alot of nasty things trying to rip your tires up. So mainly these focus on their grip and thicken treads with high psi for better ride, Compared to Downhillers that normally use lower psi, and jumpers normally in mid-range.
@SpeedRacer 650 That differs on your personal point of what components and parts you want. And what frame your gonna use them on. And power of electric ability and range. It all differs and will add into your price. Mainly the biggest will be the Motor/Battery for your idea of getting such. Highest components on my list are mainly the front fork, Hub or mid-drive replacement for rear wheel. Front hub, battery, rearwheel replacement if i go mid-drive. or crank set if i go rear hub. (Rear wheel replacement = wheel itself, cassette 9speed, 9speed chain, shifter lever, (already have deraulleur but that was around 50$ to.) (If hub, I'd still need abit of the above, but with a shimano hollowtech 2 deore 3by crank that i'll use the middle ring on after remove the inner/outer since my bike can't use a 3by system/front derailleur.) Most other parts are pretty cheap. But still good comparable to higher ends. Just gotta be abit look around for good cheap parts. (And these are all NEW parts. Not used or found on ebay.) If you were to just put a new battery, Rear rack, and front hub. It'd probably only cost you like less then 600$ (battery, motor, rack, and Bag. for your current bike.)
Well I have decided to make this a 6 month project, I was going to buy a bulls estram evo 45 am (brose s pedelec 28mph) in Germany and ferry it back to the UK at the start of next year. I need to replace/supplement my focus s27 which is also a s ped but is getting in need of tlc after 15 thousand miles. Anyway I am definatly into making my own now and plan to start in the next 2 weeks by buying your frame and motor but I was going to take my time with component purchasing just waiting for best bang for buck deals . What sort of range are you getting with your build?
Yes exactly! There’s nothing better than building your own EMTB, it free’s you from warranty issues, everything associated with dealing with big brands, you can do your own repairs or take it to a bike shop and you can upgrade bits as and when budget allows...AND of course it allows you to build something that will kill everything else out there in terms of performance!
Hi there mate. I’ve built build safe reliable bikes thats do 40mph for less than a £1k. A used downhill bike are like £500 some or less if you get em off gumtree or shpock. You can get a £20 bike with brake and suspension upgrade it would be safe enough to do 40.
I go for a cheap old downhill or full sus frames and give them a heavy duty torque arm and they all have held up fine. But the things i never cheap out on is suspension and brakes but it depends if im using regen. Current build is 16s 10ah turning batteries £200 which is good for high amperage and i can stick em on anything 10-15 miles. I wouldv gone for li-ion but there more for a permanent solution. 1000w motor but i changed phase cables and added ferrofluid etc and im running it at 70a atm. This builds for fun and ill probs feed it too much current and blow it up😂
I must admit your videos have been very helpful as last year brought a E+Plus bike from Argos front wheel motor, at first for price was very impressive had everything on it mudguards, chainguard, stand and many of items normally have to buy seperate so really felt I got a bargain never planned what to come. Just after having it for a month and lost all power and forever hit a bump chain come off and the love for this cycle started to change, it started to sound tinny and deraillur was ugly and cheap looking never went into 7th when adjusted to 7th gear wouldn't go into 1st gear. Front disc brake went funny and everything about the cycle felt cheap, looked great but everything was cheap, metal mudguards and chain protector just going back to the 70s and early 80s, that was fine for then but not today as there is better materials, so I was going to send the cycle back but watching convertions had a better idea, with it being a eBike it had places to hid cables which a normal cycle just wrap cables exterior. so ideal for convertion, First of all get rid of the hub motor convert to a mid motor so opted for the Bafang 250w, this would get rid of the nasty chain guard that when chain comes off takes 5 -6 minutes to get chain back on, no mesing with botton crank bracket motor slipped strieght through cables hidden and it has a back pannier battery soldered a better connecror got rid of their poor connectors that kept vibrating off. Also swapped deraillur from their nasty looking one, replaced metal mudguards with good quality plastic ones so took all the rattling away when riding the cycle. Had a spare front wheel and was able to use the tyres and inner tube which where probably best thing of rhis cycle, so I am now riding 35% of the original cycle as 65% of the existing parts have been replaced. What as this done to my cycle? As it was I would of given it 4 out of 10 but as it is now 8 out of 10, I need to get better disc brakes as already had a brake failure with existing brakes, I did buy a universal 160mm brake set but didn't fit properly think need a different bracket, if I could get better disc brakes this would take the cycle to a great 9 out of 10. To get 10 out of 10 I think the colour of rhe cycle needs changing but not going that far. But yes converting your own you can make it as you would like it. All we need now is the UK to cange the law concerning ebike in line with US 750w, 28mph then could really build a beauty. Mike
hi. awesome build, how much does it cost to put together. I've done an e-bike build with a ibis mojo hd and a bafang mid drive motor, yet to try it out on trails, has the motor hanging down a bit on the frame, but nice n quick on the roads. Cheers
@@andykirby heh I'm not even sure what that is, will have to look that up. You could talk to the folks at watt wagons - they're selling and prototyping the X1 so they should have all those details.
Nice bit of kit, so I have a luna cycle with a 1000W Bafang motor and I'm 130kg and it gets me around really well, the m620 is a 1500w motor which impresses me I'm got too use to the 1000w and need more. So can you get this kit shipped to Tasmania and how much in AUD. I'm talking frame, motor, wheels, brakes, etc.
I can’t afford a bike let alone an e-bike 😂 Just spent my last savings on a 305w PV panel and 600w micro grid tie inverter! When I save enough I’m buying the same again to supplement my energy usage in my shed 👍
Not sure what things are like in your country but in Australia that bike you are pushing is not anymore economical to purchase. The only advantage I can see in home build is using lithium Palomar batteries instead lithium ion. Anyway nice bike non the less
Can you please tell me where did you order your battery? What is the brand name? How long does it last or how many kilometres does it reach before it stop. Thank you
Correct me if I am wrong. Just a double suspension e-bike example. You can buy a 2020's Haibike SDURO FullSeven LT 5.0 for 4.000 euros, factory new. About the same cost as your end prodcut. By "unlocking" your Yamaha motor you can reach speeds of 45km/h + easily in 4 seconds. To be honest, the motor has superb torque itself, but in the end of the day what matters most is your leg power and gear combo. SDUROs are very customizable in general, change or add a front gear and you can reach speeds of a motorbike (70km/h). All of the above with a waranty for the frame, battery and motor, and highly trained stuff to maintain or upgrade your e-bike when it needs to. How can your custom e-bike compare to that, other than the fun-factor of making it yourself piece by piece?
It’s better in one word: Performance. This will blow an unlocked Haibike away into the dust up a mountain trail becuase the motor is 3-4 times more powerful, and as for motor reliability the motors used by haibike etc all have plastic gears! Not good but then they only really want you to ride their bike for a season and then buy the new model when it comes out😁 oh and the batteries are crazy overpriced for what they are.
I kept exact records of my build. I used my old frame and fork so Every thing else is new. Bafang mid drive kit $1482.35 added to All the other items and they add up real fast $946.00 for a total just about $2490.00 ... It was fun to build and super fun to ride. My woman hates it so there is a unexpected bonus.
Hi, your build looks great.!! If I buy this self assemble kit from you does it come with everything that your using in this video. Would I need to buy anything more to complete the build
nice project! Do you think it's possible to use the shock Fox DPX2 on a 17" frame? no risk of the piggyback to touch the battery case during the travel? thanks
I've got a pair of SunRinglé MTX39 rims waiting to be built up for my project. I used to like Mavic 20 years ago but I found Sun rims to be stronger, if a bit on the heavy side. I guess Tom Ritchey was right.
I found a excellent condition stored for 10 years downhill Canondale perp circa 2008 for $600 cad. $300?uk. Anyway, 200mm of travel and Im just finishing the cable management for a pretty clean looking install. I'm using a Bafang 750 and I have 32! Headway cells. Backpack battery pack. have to wait for a speed sensor extention cable. Its fun working on bikes everything is so well made compared to cars.
looks slick, i had better start saving!..ha ha. I love the integration of the bafang motor and battery. I have my own diy bike with bbshd but this is looking like a store bought high end bike but with much more PowAHHH!! :), Great Job!
We need to see you shredding the gnar Andy. Epic video mate. And if you're going to be a supplier for the bafang ultra motors in the UK, you'll get mighty popular. Keep up the work mate.
Very interesting. If you could compare to a main stream bike what would it be Specialised kenevo/levo or Giant, Vitus e sommet? How strong is the frame is it bike park strong? And is it solid (no rattles)when going downhill?
Yes I will do this soon, it’s very strong actually I haven’t managed to bend it yet and trust me I’ve pushed it pretty hard. Nothing rattles either and the test model is approaching 1000 miles now.😁
Great Build Andy, Looks light & Nimble, should be fantastic on tight & twisty trails. Goooooo the "Bafang Mid Drives" 💪🏼 Shit loads of Torque with all the Gear Ratios you could want. You finally crossed over from Hub to Mid-Drives 😬 lol. Those Dirt hills should be alot easier Now ! Let me know how many miles you get "Offroad" with this E-Bike
Hi, have you got a link to your shop ? Currently wanting to turn my full suspension mtb into an Emtb but was interested in seeing how much one of your frames costs as it would make the thing look and perform better Thanks
Amazing build. The peak power is around 600-700 watts on high end mtb not 250 watts but they do deliver in a more progessive way than bafang. I still trade this for power.
@@andykirby I have been tuning a bbshd for a year and still think my brose motor is more progressive. Brose meter the pedal power and match to a variable motor power. Bafang is just basic on or off at set power.
Hi Andy, great videos you've got me hooked. Can you get a carbon frame that hides the battery in the frame. Also is there an upgrade on the battrey to provide longer range.Many thanks and keep the vids coming. I am in the process of building a bike from scratch , cant wait.
Where do you get the bare frame from that’s suitable with the battery mount? I’d like to build something similar and none of this in on your website like you talk about ? Thanks
Been watching lots of your videos recently and ended up going with a bafang bbshd middrive motor rather than hub. I'm really happy with it and have since changed basically everything but my frame and wheels. The frame its on is a 2001 Kona Roast, which is a solid frame but I'd ideally like something with more modern geometry and possibly full suspension like the one in this video. Do you know of any frames that will fit a bbshd like that rather than the ultra? Cheers in advance, and please keep up the excellent videos.
Hey Andy cool bike love it! Quick question if this bike frame is designed for a bafang , will future upgraded bafang motors can replace fit into the space this bafang motor is being installed ?
Hello Andy . I bought so much bikes ! It is time to build one . I saw carefully what you have done . I would like to order more or less exactly what you did .
Lovely job Andy, don't listen to trolls in the comments banging on about legal ebikes, for over 20 years I've been involved with the worldwide ebike scene and am well known and still am riding high power ebikes, every day in London the roads are full of them and electric scooters, fact is if you are sensible, ride safely and maintain the bike you won't ever have a problem, lots of these 250w legal bikes peak at up to 800W, the police have far more urgent things to worry about than an electric bike that's producing over 250W in power.

I don’t care about the self appointed ebike police, they clearly have never ridden an ebike let alone build one😂
Poignant as fuck mate!
In the next two years, I will be building an electric bike of my own, I wanted one since my mini electric motorcycle got stolen out my years when I was young. And I finally can see it becoming a reality in the next few years. With the help of your videos and my new job in the military, i feel as though I could really do it.

Nice bike and tutorial. I’m 61 and I just went from knowing nothing about ebikes (always had regular pedal bikes, well and also a few Harleys and Hondas) to assembling a dual 1200W (2900W Peak) Ebikeling setup, including front and rear motors. Watched a couple of your videos and had it running 55km/hr in less than a day. Next I want to try building my first mid-mount bike. I’m hooked.
Awesome! Welcome to the world of ebikes! Sounds like you are taking to it like a duck to water 😊
Dual suspension is the way to go. I have built several bikes, and my favorite are ones with front and rear suspension. They ride smoother and tackle rough terrain much better. Nice!
it really depends on your budget, if you're looking to spend less than £800-1000 then front hardtail is the way to go.
I've been considering an e bike for many years. After years of looking and researching what you have built is I would say is 99% the excact bike I would have built. From the frame to the motor to the pedals. Absolute perfection. Well gel. Also what was the total cost in the end.
Nice bike! Excellent video work. This bike is a game-changer for the DIY builder.
Thank you for your contribution to the e-bike world.
Thanks for sharing this wonderful video, bro! I plan to transition 90%+ of my travel to using an ebike. I love bicycles, being outside, enjoying the journey and not adding to the pollution (and noise pollution) here in the central valley of California. I can't wait to be adjusting my time schedules to enjoy going most everywhere on my bike. Keep up the good work!
Really clean build!! Thanks for putting this video together, as usual it’s packed with value :)
Brilliant mate!! Once iv got my driving license and I'm on the road, I need to save for one of these!!! Build loads of MTB, BMX and jump bikes over the years but these look incredible! Well done to you man love everything you do! Take care bud

Hi Andy
I've just rebuilt my 21-year old Marin dh B17 with the same hope disc in a 160 mm and use a zoom hydraulic caliper fon now fits perfect works very well
Regards Mark
I test rode a $13,000 Specialized eMTB the other day... That is insane, it was pretty neat but not $13,000 neat. This is a fun video, thanks for putting it together.
Love it Thanks Andy! How about your all-in cost on the build??
3500 Pounds
@@whatcha7354 thats 5800 euros
Your builds/videos and music are top notch Andy, don’t listen to the nay sayers, ride on. I grew up building bikes from bits in the scrap as a kid and your vids inspired me to build an ebike. Parts are on route and I’m excited to get building again👌
Glad to hear that! Thanks for commenting 👊 once a builder always a builder!
No worries, I’m struggling to find a 27.5” Boost wheel set with/without tyres, could you pm me if you could me a set shipped? I take it the wheels on your bike are Aluminium?
thanks for the vid, It amazes me they are charging more for a name brand ebike than an entry level motorcycle
With 250W motor 🤦♀️
The bike you can buy from Ali Express, he put the last video in my channel about this bike, but I flew it, made it bigger to put the battery.
You Sir saved us a lot of money for Christmas. You a life saver man God Bless
I love the fact that the motor is very neatly integrated into the bicycle.
A used donor bike and you could build an amazing machine for a tiny fraction of what the mainstream manufacturers are asking. As you say, even all new it's way cheaper. They have been ripping us off asking those kinds of prices. I guess a fair bit of the 8K or whatever goes to sponsor people who try to justify that you need to spend all that on a bike.
Andrew Norris it's not ripping off as they've been investing R&D into developing this tech for decades, plus the high end ebike usually have a lot of fit and finish people hours invested into them. They just seem expensive when looking at the highest end new models that are dripping with high end lightweight yet durable materials and compared to high volume gas vehicles that we are so used to that are cheap yet are expensive to operate over time
Thanks a lot for the sound effects at 1:40. I thought my computer was crashing!
Yep Andy took you two years to get to this level of expertise well done you are the best mate.
I just recently purchased a TFT C850 bafang display with a new control box ..you beat me by
6 weeks lol...but get your self a eggrider or better have both...thats my end game ..full blue tooth connectivity to the mobile phone and a clear screen for additional info.
Love the new monster looks like Bafang and Bosch are going head to head it will be interesting to see who brings out the best products...nothing like a bit of good competition>
That way us paupers get a better choice.One day I will make a 1 hour plus video on my fat bike. Cant wait to see the next video....and when are you going to use Higo connectors ???
Cheers big man! I appreciate all your support in the comments section of every video😁 one day we may get to have a rip together😁👊
I've build a few e bikes
But they only cost me a fraction compared to the ones on this channel lol.
For £380 every single part & bike included.
I've built 3000w 72v to 84v.
Mid Drive system Ebike
29 inch wleels & 12 speed set-up at the back
And 3 at the front.
With rotor discs & 4 piston sram hydraulic brakes.
Air shock forks
It's a scott racing bike converted into a motorbike.
If I bought everything new plug & play parts it would have cost probably £4000+.
I have no idea why UA-camrs don't build cheap Ebike just to show the viewers.
I like that the battery is not integrated into the frame. This gives you the option of bigger batteries than internal battery storage allows.
Cool build
Great video. Very excited to get started with building my own e mountain bike
Just been looking at FullyLoaded London, their bikes are crazy prices and some don't have these quality components. I see you can buy this bike ready built. I have ridden 'normal' eBikes but never owned one. That is about to change, I love this build and it is pretty future proof. Would the experienced E-bikers think this is too powerful for a first E-bike, all be it for a long time cyclist. My thinking is for £3400 this bike gives so much more than I have seen in London. I really am thinking of buying one fully built as it does cost a lot and prefer the idea of Andy building my bike.
Great video! You should get in touch with the guys on EMBN show and let them try it out to compare it to the other bigger brands. Keep up the good work!
The trouble appears to be they are sponsored by the big brands who charge £8K for a bike. If you look at their past comparisons they have not always compared like for like.
@@andrewnorris5415 yeh they are not into diy or higher power..only promote boring 250w bikes!
Great vid you talked about the cost of E- bikes at the beginning been very expensive but in your video you did not mention the total cost off the build ??

How much is that in US dollars please? Ty

@@kaybeane7196
If you use Fox shocks front and rear and had to buy everything new or newish I would guess you’re looking to spend $5k or a little more. That’s my guess.
@@chucknoob7041 ok. Thank you for the info
Andy- The EX1 crank arms you have are "self extracting"(ie you don't need a crank puller) the little "cap" is meant to stay in place and the 8mm hex tool goes through it- when you undo it the 8mm crank bolt inside pushes against the (10mm) "cap" and pops off the arms... and be warned the standard thread crank pullers are not quite the same thread and size as the EX1 threads.... removing the 10mm "cap" and using a standard puller you may rip out the threads....
is it the same for BBSHD 1000w pedals?
Use my bafang converted voodoo wazoo to go to work instead of the car ( milled 10mm off the bottom bracket) .Just got a 31AHr 48V battery from Mike at GreatMax , made to order in China, delivered DHL to the door, duty paid. very happy.
Hi Andy, just came across your video and really appreciate what you’ve shown.
I love trail riding and currently have a Cannondale Scalpel. I would love to keep riding to keep healthy but at 43 it is becoming increasingly more demanding.
I agree with most that current emtb are way overpriced for the average Joe out there and BAFANG motors even seem to offer a superior spec than most fancy bikes on the current market!
I would like to do what you’ve done (build from scratch) as a statement and for the feeling of building it with my hands.
May I ask; how much in terms of parts all together have you spent to put the whole bike together??
My 36V350W TSDZ2 mid drive motor has a pretty good 80nm of torque on a carbon fibre frame on 24 Spoke Zerolite Pro Vuelta wheels which are pretty hard core wheels. My bike is set up for the road using Michelin Wild Run'R Advanced 1.1" slick tires with MR TUFFY tire liner, I've got both the 36T & 48T Chainring on the front. With the tires I'll probably get 1 puncture from the life of the tire after it's worn down to braid under the outer casing which has worn off after thousands of kilometers riding.
This is incredible man! Keep making the diy vids, you inspired me to build an emtb myself
Currently rebuilding my full suspension voodoo green ebike can’t wait till it’s finished with all my customisations gonna be one of a kind !👌🤘
Sounds good, I’ve always liked the look of those, they need some uprated bits on and could do with more power😁
Yh I’ve derestricted mine mate with the speed box 2.0 way better plus it’s being customised throwing loads of new purple parts on it will look the dogs doo dars when it’s all done !🤘😆
@@andykirby you supply cheap low quality components on your bikes so don't comment on upgrades when you give out dnm suspension
I'm guessing this is the 17" frame, and there is also a 19"? Do the frames accept 29er wheels? Is there an advantage/disadvantage to running a 29er wheel? Would you consider an advantage of running a smaller rear and larger front like a dirt bike?
Might be harder to pedal tho so idk
Awesome videos! What is the cost to complete this build ? Thanks
Sweet ride. Gotta love Bafang. Just finished my build. BBSHD 1500 w 52v 13mwh battery on 26" trek hard tail with new-ish fork. Then every thing else is new and as light as possible making a 46.1LB (20.95kg) death machine with a top speed of 41.6mph ( don't know in kph) because we ride on the right side of the rode here. However my next build after this one gets stolen will be with a frame and battery similar to what you started with but maybe carbon idk. Ride it like ya hate people. Later
Did you also put a throttle on it? I want to do a similar build that has both throttle and pedal assist options thanks!
@@gregorypatzelt6964 yes a right hand 1/2 twist throttle next to Shimano rapid fire shifters and Shimano m355 hydraulic disc brakes leavers. on the left side the color display. I was told with a half twist throttle that I could not Mount the index shifters however I had no problem and it works fine for me I even had my brakes customized with the rear brake on the left and front brake on the right coming from a motorcycle background I'm more familiar with it that way and everything was mounted on a carbon fiber handlebar. Chain line was the biggest problem but after installing a LunaCycle Eclipse chain ring its perfect. I have even been pulled over for speeding by the local sheriff department luckily no ticket.
how much maintenance is it on the BBSHD 1500 w and your drive train?
would it be less if you had a BBSHD 1000 w?
Thanks for putting the video together It looks great... I was looking into doing my own e-bike but after watching your video very tempted to invest in your frame and build one from scratch.
You mean his generic ali express frames
I think the caples passing through holes in the frame should go through grommets to avoid chafing, especially the battery output leads. I hope the battery output is fused.
absolutely amazing video, this thing looks like a beast !! :O
Sick ass build Man! Definitely digging the bike. Would love to learn to build my own. Your enthusiasm is contagious. Keep the vids comin brotha! bIG uP!!
Impressive. Looks really cool. You really know how to build cool e-bikes. the only thing i miss is the mud guards for the tires and something to seal the connectors, to prevent rain and moisture from comming in. Great job i really admire your work and fearless attitude and just getting the job done👍👍🐿. Looks like a really cool 👍😊
That’s a really interesting development. I will follow with interest.
Yeah... This is great. I love building and tinkering so this is perfect.
didnt see the link to the frame, where can I see and or buy that?
So if I want the same bike but in pieces so I can put it together how much would that cost including shipping to Australia mate ? 👍
$3300 AUD for the bike frame and drive train (so would need suspension and brakes etc) or near 7k for the bike fully built.
Honestly you can build something far cheaper with the same performance using local bought parts.
oz-ebikes. com is a good place
Rohan Hine where are you getting this $7k number from?
Nice Bike, excelent work! do you prefer this bafang over a nice and powerfull hub motor? it seems to be a bit lighter.
Great job @AndyKirby. You achieved what some of us only dream about. I'm curious where the motor controller is hidden. It must be built into the motor is it? What mech have you got? Seems the chainwheel is very large. Yes you need to publish the weight. What are the options for brake cut-outs using Hydraulic brakes? Good luck with it. Cheers.
90% of mid-drives have built in Controllers into the motors. That's why their abit more bulker. Mid-drives are more torque because their using the chain for power performance, while hubs require the power straight off the bat in the wheel So some are direct or geared, Requiring the ESC to be outside for better cooling. But Mid-drives have so much torque their motors don't get as hot. So they can handle more load that's why their dependent on the chain for power.
@SpeedRacer 650 Oh no. I got something cheaper and nicer upgrade platform i like. I got a Hyper-Eride mountain bike with V-brakes. (Can also support disc brakes. but i'ma stick to V-brakes atm.)
It's gonna be like less then 3500-4000$ once fully upgraded. Stock bike is 645$ atm, will have Dual battery packs, Dual motors (Front and Mid-or Rear hub still deciding which system to go with on the rear.), Full Shimano Deore system 9speed, Rockshock Solo air fork, Alum handlebars/Seatpost/Stem/Peddles/etc. With 3point mounted rack for cargo. It has flush mounted battery (that'll be used for ether rear or mid-drive.), Another battery above it as a waterbottle design for front, or extra batteries in rear rack. Dual throttles.
@SpeedRacer 650 Yes it's a hardtail vs a Full suspension. Roughly similar.
Fun thing about building your own kind of bike tho. Is basically the only thing you really need to swipe if you want it a different bike. Is the frame. Well course in your case or so, the frame requires the specific motor and battery. But if you bought a normal frame you could use a mid-drive conversion kit and waterbottle design battery (that fits like a normal waterbottle drink holder.).
This bike you could also technically upgrade to dual motors to, just get a seatpost rack, and add a pack with a battery for a front hub. And your good to go. Not much weight added, maybe 10-15pounds but since the battery will be in the rear, and the front hub. it'd still keep it pretty balanced.
The weight on mine stock is 50pounds. This is pretty much roughly the exact same as you find normally on high end ebikes to around 45-60pounds is the targeted range for mountain ebikes. Roads will be probably lesser since their general design is speed, so lightweight is mainly their focus.
With the rack and cargo bag with abit of stuff i'm adding 10pounds yes. And a battery 5pounds and a hub 5pounds. So extra 20pounds from the stock 50. But i'm keeping weight pretty evened across the bike. I'll have 2batteries in the middle of the frame, hub front, and ether hub rear or mid-drive middle, and if maybe extra battery or so in rear rack. But mainly rear for cargo. Overall the 20extra pounds isn't gonna be much pain including if both my drives are are good on torque and power. And i have good tread with large nobs with good psi to handle the weight and grip.
I had a yukon trail cruiser that was steel frame, ran at 24volt 250watt 10ah lithium battery, stock weighed 80pounds, still hit around 15-20mph on it and 20miles of range, even after i added like 30pounds extra with more cargo weight i put on, It was a beast of a cruiser. And all on throttle control no peddling. Even off-road and it shredded pretty well. Compared to trails alot of mountainbikers go that are pretty fairly hard, Even my yukontrail shredded threw where i go, which normally has a softer kind of road. So if that could handle with such a lower motor. I'm sure the upgrades and abit lesser weight my Hyper has, Will rip much better with it's power and dual performance.
@SpeedRacer 650 Mountain biking isn't about speeding 25mph+ down hill. Mountain biking is about going off-road and exploring. People seem to mistaken what the point of mountain biking is really. It's off-road tough terrain riding. Not about zipping downhills and shredding inches from cliffs, or jumping 50feet off ledges.
Any mountain bike will have it's limits to how much beat you can smash on it.
If you want downhill, you want some good suspension to dampen the hips and humps of the fast attacks of the rough terrain while zipping down. With a pretty good strong frame. Rest of the components can be whatever your choice since they have no relation to the strong of the frame or suspension.
If you want a Jumper. you need to have a strong frame, with stiff suspension to have a slower impact. Meaning the suspension isn't gonna be plush on off-roading, but will take the impacts much better on jumps.
If you just want a overall mountain bike. Any bike normally will do. Since your main focus is to enjoy riding, Not zipping fast or jumping crazy. But riding the rough harsh terrain, which is gonna have alot of nasty things trying to rip your tires up. So mainly these focus on their grip and thicken treads with high psi for better ride, Compared to Downhillers that normally use lower psi, and jumpers normally in mid-range.
@SpeedRacer 650 That differs on your personal point of what components and parts you want. And what frame your gonna use them on. And power of electric ability and range.
It all differs and will add into your price. Mainly the biggest will be the Motor/Battery for your idea of getting such.
Highest components on my list are mainly the front fork, Hub or mid-drive replacement for rear wheel. Front hub, battery, rearwheel replacement if i go mid-drive. or crank set if i go rear hub. (Rear wheel replacement = wheel itself, cassette 9speed, 9speed chain, shifter lever, (already have deraulleur but that was around 50$ to.) (If hub, I'd still need abit of the above, but with a shimano hollowtech 2 deore 3by crank that i'll use the middle ring on after remove the inner/outer since my bike can't use a 3by system/front derailleur.)
Most other parts are pretty cheap. But still good comparable to higher ends. Just gotta be abit look around for good cheap parts. (And these are all NEW parts. Not used or found on ebay.)
If you were to just put a new battery, Rear rack, and front hub. It'd probably only cost you like less then 600$ (battery, motor, rack, and Bag. for your current bike.)
Well I have decided to make this a 6 month project, I was going to buy a bulls estram evo 45 am (brose s pedelec 28mph) in Germany and ferry it back to the UK at the start of next year.
I need to replace/supplement my focus s27 which is also a s ped but is getting in need of tlc after 15 thousand miles.
Anyway I am definatly into making my own now and plan to start in the next 2 weeks by buying your frame and motor but I was going to take my time with component purchasing just waiting for best bang for buck deals .
What sort of range are you getting with your build?
Love the bike! Fantastic components and those Hope brakes are like jewelry! I know what I want for Xmas😉.
Very interesting video. Huge value for money if done properly. I might go this way for my next emtb
Yes exactly! There’s nothing better than building your own EMTB, it free’s you from warranty issues, everything associated with dealing with big brands, you can do your own repairs or take it to a bike shop and you can upgrade bits as and when budget allows...AND of course it allows you to build something that will kill everything else out there in terms of performance!
I use the bbs02 motors and taking my bikes uphill is as fun or more fun than going down hills. Flat trails are a blast.
nice build next do a budget but very powerfull high power build 4kw or 5 kw peak.
You can't make this in a budget with the proper safety
Hi there mate. I’ve built build safe reliable bikes thats do 40mph for less than a £1k. A used downhill bike are like £500 some or less if you get em off gumtree or shpock. You can get a £20 bike with brake and suspension upgrade it would be safe enough to do 40.
@@yakz9885 I have an similar build than Kirby but 11kW if you want 4-5kW you need expensive batteries and frames as well as brakes and suspension
I go for a cheap old downhill or full sus frames and give them a heavy duty torque arm and they all have held up fine. But the things i never cheap out on is suspension and brakes but it depends if im using regen. Current build is 16s 10ah turning batteries £200 which is good for high amperage and i can stick em on anything 10-15 miles. I wouldv gone for li-ion but there more for a permanent solution. 1000w motor but i changed phase cables and added ferrofluid etc and im running it at 70a atm. This builds for fun and ill probs feed it too much current and blow it up😂
They are easy to put together its all the money. Need the right tools and you are Good to go. Thanks for video 👍🇨🇦🍻🚲
I must admit your videos have been very helpful as last year brought a E+Plus bike from Argos front wheel motor, at first for price was very impressive had everything on it mudguards, chainguard, stand and many of items normally have to buy seperate so really felt I got a bargain never planned what to come. Just after having it for a month and lost all power and forever hit a bump chain come off and the love for this cycle started to change, it started to sound tinny and deraillur was ugly and cheap looking never went into 7th when adjusted to 7th gear wouldn't go into 1st gear. Front disc brake went funny and everything about the cycle felt cheap, looked great but everything was cheap, metal mudguards and chain protector just going back to the 70s and early 80s, that was fine for then but not today as there is better materials, so I was going to send the cycle back but watching convertions had a better idea, with it being a eBike it had places to hid cables which a normal cycle just wrap cables exterior. so ideal for convertion,
First of all get rid of the hub motor convert to a mid motor so opted for the Bafang 250w, this would get rid of the nasty chain guard that when chain comes off takes 5 -6 minutes to get chain back on, no mesing with botton crank bracket motor slipped strieght through cables hidden and it has a back pannier battery soldered a better connecror got rid of their poor connectors that kept vibrating off. Also swapped deraillur from their nasty looking one, replaced metal mudguards with good quality plastic ones so took all the rattling away when riding the cycle. Had a spare front wheel and was able to use the tyres and inner tube which where probably best thing of rhis cycle, so I am now riding 35% of the original cycle as 65% of the existing parts have been replaced.
What as this done to my cycle? As it was I would of given it 4 out of 10 but as it is now 8 out of 10, I need to get better disc brakes as already had a brake failure with existing brakes, I did buy a universal 160mm brake set but didn't fit properly think need a different bracket, if I could get better disc brakes this would take the cycle to a great 9 out of 10. To get 10 out of 10 I think the colour of rhe cycle needs changing but not going that far. But yes converting your own you can make it as you would like it. All we need now is the UK to cange the law concerning ebike in line with US 750w, 28mph then could really build a beauty. Mike

Sick build mate! Have u looked at adding a bac 8000 controller to get more power... ?
Prob the best build diy ebike out there. just one thing i will change is spring rear shock and prob. 38 in front..
hi. awesome build, how much does it cost to put together. I've done an e-bike build with a ibis mojo hd and a bafang mid drive motor, yet to try it out on trails, has the motor hanging down a bit on the frame, but nice n quick on the roads. Cheers
I just smacked a Tongsheng kit on my full sus, cost 500 quid and works well, only has a single wire that's easy to hide too
Nice! The Bafang Ultra is a beast. You can also buy one shipped with the Archon X1 controller upgrade 2500w peak, can't wait to try it.
Has thr Archon X1 got flux weakening?
@@andykirby heh I'm not even sure what that is, will have to look that up. You could talk to the folks at watt wagons - they're selling and prototyping the X1 so they should have all those details.
Nice bit of kit, so I have a luna cycle with a 1000W Bafang motor and I'm 130kg and it gets me around really well, the m620 is a 1500w motor which impresses me I'm got too use to the 1000w and need more. So can you get this kit shipped to Tasmania and how much in AUD. I'm talking frame, motor, wheels, brakes, etc.
I can’t afford a bike let alone an e-bike 😂
Just spent my last savings on a 305w PV panel and 600w micro grid tie inverter! When I save enough I’m buying the same again to supplement my energy usage in my shed 👍
Beautiful build brother! Clean and tidy work!
Not sure what things are like in your country but in Australia that bike you are pushing is not anymore economical to purchase.
The only advantage I can see in home build is using lithium Palomar batteries instead lithium ion. Anyway nice bike non the less
Can you please tell me where did you order your battery? What is the brand name? How long does it last or how many kilometres does it reach before it stop. Thank you
Nice build! Where can I purchase the frame?
Here: www.cloudsto.com/ebikes/kirbebike-vapour.html
Correct me if I am wrong. Just a double suspension e-bike example. You can buy a 2020's Haibike SDURO FullSeven LT 5.0 for 4.000 euros, factory new. About the same cost as your end prodcut. By "unlocking" your Yamaha motor you can reach speeds of 45km/h + easily in 4 seconds. To be honest, the motor has superb torque itself, but in the end of the day what matters most is your leg power and gear combo. SDUROs are very customizable in general, change or add a front gear and you can reach speeds of a motorbike (70km/h). All of the above with a waranty for the frame, battery and motor, and highly trained stuff to maintain or upgrade your e-bike when it needs to. How can your custom e-bike compare to that, other than the fun-factor of making it yourself piece by piece?
It’s better in one word: Performance. This will blow an unlocked Haibike away into the dust up a mountain trail becuase the motor is 3-4 times more powerful, and as for motor reliability the motors used by haibike etc all have plastic gears! Not good but then they only really want you to ride their bike for a season and then buy the new model when it comes out😁 oh and the batteries are crazy overpriced for what they are.
@@andykirby Thanks for replying.
Really really nice....probably the best i have seen
Andy Kirby I have a gt sanction pro 2016 how much would it cost me to make it into a ebike like that
I kept exact records of my build. I used my old frame and fork so Every thing else is new. Bafang mid drive kit $1482.35 added to All the other items and they add up real fast $946.00 for a total just about $2490.00 ... It was fun to build and super fun to ride. My woman hates it so there is a unexpected bonus.
@@rodneyrodgers141 Time for a new woman.
It must have been mentioned before but a dropper seat post makes such a difference
Hi, your build looks great.!!
If I buy this self assemble kit from you does it come with everything that your using in this video. Would I need to buy anything more to complete the build
nice project! Do you think it's possible to use the shock Fox DPX2 on a 17" frame? no risk of the piggyback to touch the battery case during the travel? thanks
Thanks for the video, it’s innovative & inspiring 👍 🚲
Sometimes I do long rides. Watz the range? Cost to build?
How fast will this bike go?
This ebike is exactly what we need :)
i reccomend mavic e deemax pro wheels they are ebike specific and pretty much indestructable
Interesting thanks!
I've got a pair of SunRinglé MTX39 rims waiting to be built up for my project. I used to like Mavic 20 years ago but I found Sun rims to be stronger, if a bit on the heavy side. I guess Tom Ritchey was right.
I found a excellent condition stored for 10 years downhill Canondale perp circa 2008 for $600 cad. $300?uk. Anyway, 200mm of travel and Im just finishing the cable management for a pretty clean looking install. I'm using a Bafang 750 and I have 32! Headway cells. Backpack battery pack. have to wait for a speed sensor extention cable. Its fun working on bikes everything is so well made compared to cars.
looks slick, i had better start saving!..ha ha. I love the integration of the bafang motor and battery. I have my own diy bike with bbshd but this is looking like a store bought high end bike but with much more PowAHHH!! :), Great Job!
We need to see you shredding the gnar Andy. Epic video mate. And if you're going to be a supplier for the bafang ultra motors in the UK, you'll get mighty popular. Keep up the work mate.
Dream build wow 😻

@@-joo3033 no onley bafang g510
Great video Andy, how long does it take to fully charge and how far can you go if you are not riding it like a maniac? Thanks!
Very interesting. If you could compare to a main stream bike what would it be Specialised kenevo/levo or Giant, Vitus e sommet? How strong is the frame is it bike park strong? And is it solid (no rattles)when going downhill?
Yes I will do this soon, it’s very strong actually I haven’t managed to bend it yet and trust me I’ve pushed it pretty hard. Nothing rattles either and the test model is approaching 1000 miles now.😁
Nice... Will the smallest frame take the largest battery and what diameter wheels will it take? Thanks.
Great Build Andy, Looks light & Nimble, should be fantastic on tight & twisty trails.
Goooooo the "Bafang Mid Drives" 💪🏼
Shit loads of Torque with all the Gear Ratios you could want.
You finally crossed over from Hub to Mid-Drives 😬 lol. Those Dirt hills should be alot easier Now !
Let me know how many miles you get "Offroad" with this E-Bike
which is the best frame to work on for a great build, and is it possible to use a motorcycle seat instead of the standard seat and seat post?
Are you able to program the Ultra like you can a BBSHD?
Hi, have you got a link to your shop ? Currently wanting to turn my full suspension mtb into an Emtb but was interested in seeing how much one of your frames costs as it would make the thing look and perform better
Thanks
Where do I buy the frame?
Great build! so how much does it weigh?
Amazing build. The peak power is around 600-700 watts on high end mtb not 250 watts but they do deliver in a more progessive way than bafang. I still trade this for power.
Ah..but have you tried this bafang because you can tune every parameter 😁
@@andykirby I have been tuning a bbshd for a year and still think my brose motor is more progressive. Brose meter the pedal power and match to a variable motor power. Bafang is just basic on or off at set power.
Hi Andy, great videos you've got me hooked. Can you get a carbon frame that hides the battery in the frame. Also is there an upgrade on the battrey to provide longer range.Many thanks and keep the vids coming. I am in the process of building a bike from scratch , cant wait.
Where do you get the bare frame from that’s suitable with the battery mount? I’d like to build something similar and none of this in on your website like you talk about ? Thanks
Been watching lots of your videos recently and ended up going with a bafang bbshd middrive motor rather than hub. I'm really happy with it and have since changed basically everything but my frame and wheels. The frame its on is a 2001 Kona Roast, which is a solid frame but I'd ideally like something with more modern geometry and possibly full suspension like the one in this video.
Do you know of any frames that will fit a bbshd like that rather than the ultra? Cheers in advance, and please keep up the excellent videos.
Hey Andy cool bike love it! Quick question if this bike frame is designed for a bafang , will future upgraded bafang motors can replace fit into the space this bafang motor is being installed ?
Cheers! It's only designed for this motor so unless bafang make an updated m620 model then no.
Great video, I’d love to have a go at building my own bike.👍🏼
Hello Andy . I bought so much bikes ! It is time to build one . I saw carefully what you have done . I would like to order more or less exactly what you did .
I think I'm sold. Ill probably buy two of these, one for me and one for the wife. Thanks.
Very sharp looking ebike. Great job. Cheers😁👍
Really great bike! What would the cost be for all the parts to do this build?
Cool bananas mate, this looks super interesting!! Have to convert to twist grip throttle as I'm a m/cycle trail bike rider at heart.
Yeah you can do that easy!
