This as you well know is the most powerful setup you have done yet. The power will be closer to your MT-09, I would recommend putting on your heavy armor if your doing a high speed run. If your not going to use torque arms then don't bother using regen as the motor will rip off the rear triangle. These QS205 are no joke, some people use them to replace boat motors and on the open sea they hit 40+ mph. Myself I went for a QS205 5T with 200amp sabvoton and hit 30mph which is quick enough but the extra torque and acceleration is like warp speed and the hill climbs are damn good.
Hmm, I might be brave enough to try and cold set Aluminium, and then I might be brave enough to put a 5000w+ wheel on a bike…. But NO WAY I’d be brave enough to put a 5000w+ wheel in dropouts I’d just cold set!! 😂😂😂. May the force be with you!
Fatbike frame would also be another good frame as they are a 160mm dropout! Good luck with the build dude, you will probably need a chain tensioner. Keep up the good work, good to see lewis too:)
Yeah man the motor feels heavy untill u ride it then pulls asif it weighs nothing. I got a 20s5p molicel p42a 300ant bms bat and a 150a sabvoton fit into the triangle of a large bike with a 141mm qr boost spacing. With this 205 3.5t motor. Clean as build. But yeah going 128v I expect mid 80s bro be careful ffs.
The Sur -Ron of this set up reaches 75 miles per hour with a 70 kilogram rider . Depends on gradient and high current draw makes battery terminal voltage dip as 26650 array cells are used . I build bicycle light batteries with the Panasonic ones .
A bet that bike will still pull at 80mph, there a lad on u tube, he's got 5kw, I read in the comments his friend had it up to 76mph, but was frightened to go any faster, anyway Good Job Steve, this is what I wanted but my dad's was complaining lol, can't wait to see you go on it. 👊 E-BikeGuy is the channel I'm talking about.
Steve, stretching the "drop-outs" or COLD SETTING is probably ok on a steel frame but on an ALLOY frame it's not advised because of two reasons,...the first being the COLD SETTING thing is a bend in the CHAIN/SEAT STAYS not a bend in the DROP-OUTS so the PLATE FACES of the DROP-OUT will always be slightly angled on the interface for the hub when it's stretched out. The interface being at an angle means there is an increased risk of hub slipping within the drop-out as the clamping force off the skewer is not working in a clean and linear face....be careful mate.
Here in the US, we're building hardtails doing 60mph. I've got something in the works. Currently I've hit 55.7 downhill, 52 on the flat. Others have done much better.
Get down the marina and buy a anchor in case you need to do a emergency stop, or call Southend Airport see if they will let you do a test run. You will have to wear a mankini for aerodynamics, you would definitely get hits, can't wait it will be rappid
Steve great introduction on your project.can see you buzzing over this the bike colours as they are look wicked. Can't wait for the next episode. Can see them now in ore keep the good work going .
For spreading the dropouts on a steel frame I just use a piece of threaded rod with a couple big washers and nuts. The nuts and washers on the threaded rod pushing outward on the dropouts.
I really hope you get a parachute or wind brake and really good amount of space like miles of it.... Good quad piston brakes ect playing with lava here lol
My bike was based on this frame just a different colour. I put 1500w on mine and I'd say that was enough the frames are good but I doubt they'll take a motor pushing the power you want to atleast with out modifying it heavily. Brakes are shit and Id change those my derailleur broke and I ran my bike for ages with out one. Can't wait to see how this turns out
Great content as always. I think you are going to need a chain tensioner of some kind for single speed since you have no horizontal dropout adjustment on that frame. Unless you get really lucky like Berm Peak did. By the way, the girth of that motor cable is impressive :o.
I've done this a couple of times for single speed and that is to leave the rear derailleur on as a chain tensioner. You can keep it in a particular set with a screw or two or to put a very short cable with a blind end and adjust to the correct position. Even an old cut spoke with the end bent over can substitute for a cable.
Also I feel like that bike is busted for sure after stretching it that far. If it’s not then awesome but I’d assume it is messed up no matter what and to assume it’ll bust as some point. Is there a better bike or at least a better way to stretch a drop out? Is this a new technique? Or do other people stretch their dropouts to fit too? Please comment if you’ve done this yourself and how you did it and when you woke up from your comma after your frame failed on a ride?
Me worrying about the vertical alloy dropout for my 1500w build.. lol certainly wants some beefy torque arms The Kona frame Tony from vortex did I forget how fast he was going on it, was in the 60's I think looked pretty scary. Think ya will get some proper donuts out of it.
Ps. Had my dad help me stretch my dropouts from 135mm to 141mm... Dude used some oldskool 1960 style hammer and wood wedging method😆🤷🏾♂️... All I kno it worked 😆😆😆💯
I would be worried about the steep head angle, bike is designed to be stable for xc climbing and mellow decending, could be a tank slapper at speed pal!
Had a voodoo MTB and sold it because i needed some space for my new bike, it would have been perfect for an electric bike build,solid bike with shimano Acera gears and Clark's hydraulic brakes (best cheap brakes going)love your channel 👍🚴🏴
Sur - Ron is 12 kw . Top speed 100 mph . Seen this with my motorcycle alongside at a local dragway . We put 240 volts on it and it made a great firecracker .
My motorcycle mechanic has seen 192 km / h at a dragway but the motor started to 🔥 out as the controller couldn't dissipate heat properly on the frame . It was a 40 degree celsius hot day . Some Sur - Rons have failed due to hot weather conditions and running them at 160 - 200 percent over voltage .
those heavy duty cables, hell i bet they pass some extreme amps WOW! damn and look at that controller.. another WOW! the angle of that controller on the frame looks perfect
I was running 9.2kw on a Voodoo Canzo mtb. Before I hit black ice on it. Now it's an EEB Enduro, running 13.8kw... you're considering 20-30kw!?! On hardtail aluminum frame? Good luck & God Speed my friend! A big factor on your top end will be internal copper winding turns of your 5kw motor, a 3T or 3.5T will give you a much faster top end and less torque than say a 5T, which is the opposite.
I Steve great video To save time mounting your controller could you just fit a cycle rack over rear and bolt it flat on there Yes be ugly but jts made for a record run make it as simple as possible then if it works tidy the looks up and spend time fabricating brackets Guess I'm as gear as you to see it run thanks john from barnsley
Don't struggle to get your rear wheel in like this,its hard to watch,get a wooden pallet,cut out the inner timber so your left with a wooden frame or just build a frame ,then put it over the rear end of bike and then attach ratchet straps ether side of frame and stretch ,the easiest way to fit a thight wheel
Looks stunning. I think it definitely deserves a far stronger suspension fork. Something like a coil Fox 36 or even some RS Totems perhaps, they'd look awesome!
Your accent is top class. I have been to Southend and it is a class place. Keep up the good work. Would be good to see you convert a road-bike (eg a boardman race bike) to a 5000 watt electric.
I can’t wait for the update. I was looking at this wheel for a while but see batteries are so expensive. Which one should be used or where is the best place to buy such a battery? Thank you.
Should have just bought a fat tire bike frame, plus Steve your gonna have to get some custom fabricated torque arm plates and I’m not talking about those hose clamps ones 😂
If you're looking for a fun and ridiculously fast mountain bike build then look up an AGNI/Lynch motor, here is some more information (the gist of it is that it's a 25lb motor that can output up to 50hp) The Lynch motor is an unconventional design with a disc armature. It marries the advantages of a conventional, wound armature motor with the benefits of a flat (printed circuit) motor. It is similar to a pancake motor, but is more powerful than any of these technologies. The disc armature has magnets on both sides, doubling the available flux density and shortening the magnetic path. It therefore packs more power per pound and per cubic inch than any other motor technology. Of course such a revolutionary motor is not for every application - it is not as cheap as wound field motors, but for many applications it is a far superior motor. It has a previously unheard of power to weight ratio and also power to volume ratio. It is also highly efficient because of the double magnet design and associated short magnetic path. It also includes integral fan cooling. The Lynch motor is an important development which spurred other motor designers to improve their products to remain competitive, such as synchronus permanent magnet machines. As a result of the competition between manufacturers the cost of high performance motors and controllers has fallen dramatically. We hope the cost of solar cells also reduces to allow renewable transportation to develop as a viable alternative to carbon fuels. Cedric Lynch built his electric bike around a mid-drive configuration, also building one of the worlds most efficient light weight electric motors to power his rig reliably at 60-MPH for significant distances. He would later set several world records with his axial flux motor and bring it to market as the Lynch / Agni motor. Briggs and Stratton would eventually buy this technology which would lead to the Etek motor, which is now famous for making high speed efficient electric hot rods. Cedric uses to achieve high speeds is by following the rules of aerodynamics, and building a bike that is as aerodynamic and as efficient as possible. The other builders on this list bypassed this step, and Cedric uses this bicycle as daily transportation on real commutes. Although this high-efficiency motor uses “old school” brushes, this fact allows builders to use very affordable controllers. He has proven his design choices through thousands of miles of commuting, and the Lynch motor is highly respected. Cedric Lynch is known as the creator of the Agni Motor, a highly efficient electric motor that weighs around 25 pounds and can put out as much as 50hp. Cedric Lynch is a British 'mad scientist' type mechanical engineer obsessed with the idea of greener transportation. His interest has been in building a super efficient yet powerful vehicle that can serve as a car replacement. He started thinking of his own design for an electric motor in 1983 when he began entering competitions organized by the Battery Vehicle Society regarding building an efficient electric vehicle. At the time there was no reasonably priced DC motor with descent efficiency so Lynch decided to build his own utilizing modifying existing motors with old tin cans that he would spread out flat to use as cooling fins. Surprisingly using rudimentary materials and a garage work bench, Cedric was making better more efficient electric motors than any of the universities were able to manufacture in state of the art workshops. Cedric then came up with a motor design that could be cheaply manufactured and began manufacturing his own motor that he could sell to the public in 1988 and the Lynch Electric Motor Company was born, known as LEMCO. Cedric first used his motor to create a small boat called “The Spark” that would set an electric boat efficiency record. From there Cedric turned his attention to bicycles, an application generally considered too small for a lynch motor at that time. Cedric mounted his motor in recumbent bike, allowing him space to eventually use a set of thundersky lithium batteries. The resulting aerodynamic recumbent bike had a top speed of 60mph and still managed an incredible range of 150 miles. Cedric rode his recumbent creation everywhere as a daily commuter, putting an amazing 50,000 miles on the machine - technically a motorbike. Briggs and Stratton, the US firm famous for lawn mower engines, bought the technology and used it in their E-Tech Motor, and Cedric went on to manufacture his latest incarnation of his lynch design into the Agni motor, which is used in go karts, sailboats, motor boats, and even small airplanes. The Lynch designed motors all have the same traits. Brushed motors, around 25 pounds in weight and they are able to put out enormous power compared to their weight. Sometimes as high as 50 hp (depending on amperage ran through the motor) at an incredible 98% efficiency. Lynch Motors are also the most often used motors in electric motorcycle racing applications. Cedric's zero-emission motorcycle, which has a top speed of 120mph, was shown in action winning the world’s first zero carbon race - the TTxGP in the Isle of Mann. The idea for the electric motor has been snapped up by the 56-year-old’’s friend Arvind Rabadia, who together with his brother Hasmuk Rabadia had been thinking of starting a business in India. They have now set up Agni Motors to make further-improved versions of Cedric’s motors Despite Cedric’s breakthrough invention he has no formal engineering qualifications and taught himself the techniques needed to construct his engine. He first became interested in electrics when his parents bought him a book entitled How to build things from things found at home. The Etek motor is a brushed 25-pound pancake shaped motor that puts out enormous power for its weight. Depending on amperage and voltage the Etek can easily provide between 15-horsepower and 30-horsepower reliably and consistently (11-kW / 22-kW). A perfect platform for a powerful electric bike if you do not mind the weight. Although brushless motors are considered more modern, a brushed motor like the Etek allows the builder to use very affordable controllers. Cedric-Lynch invented the motor and sold it to Briggs and Stratton which US company produced the Etek at a lower price (around $600). In the late 90’s early 2000’s it was the way to go for a high-power / light-weight electric vehicle. Many small E-vehicle records were set using the Etek motor. Finally, the market had a relatively lightweight and powerful electric motor available to the masses. In essence, the Etek allowed hot rodders to build electric bikes. Before the Etek very few people had ever achieved 50mph on an electric bike. Even today, Etek motors (and newer incarnations of the Etek motor) are used to make some super fast electric bikes. In the case of Liveforphysics, the fastest E-bikes ever. Liveforphysics used a newer version of the Etek (the Agni motor), to achieve speeds of over 70mph, and dominate a recent hill-climb event. Every Etek I have ever ridden has been characterized by brutal off-the-line acceleration, usually to a point where you have to apply the throttle very carefully or get thrown off. However, it is possible to run an Etek at a lower voltage or lower amperage and have a very manageable, safe, and sane electric bike that will not burn out on you, no matter high steep the incline.
best of luck with your build. I love to see a powerful ebike. There are only a few frames i'd feel confident in stretching and a halfrauds voodoo isn't one of them. but, hey - you gotta try it and push the limits.👍 life would be boring otherwise
Vantastic job Pitbull.Do you want to modify my 26" Mountain bike? I have duel suspension and the best thing,it's brand new.If I can get up around 35 mph that's all I want. Nothing radical like your beast, ha. Looking forward to the next video for real.Keep up the good work.Your a natural. I'll keep watching! Craig T.
Any riding can put the motor or controller at risk if you push it to hard for too long. Couldn't say for sure but most factory ebikes are restricted for UK law I doubt unlocking them to their normal potential would pose much risk on the components. A lot of mid drives are 750w restricted to 250. That's not to say any old dodgey3rd party plug in device is safe
my guess is that the hub motor weight is about 10-15 kg :D and batterybackpack is a baaaad idea, discovered by myself in a crash the bike CG is way of.
Be careful about what Mah lipos you use, too small of a capacity and they wont handle the amps your after. I tried it with some 9000mah lipos using 4, 4S in series and couldnt ask for more than 50amps before lipos where getting hot. If you used the 20000mah turnigy lipos you might have better chance of success
Just make sure you wear some good safety gear when you get this beast finished steve not the flip flops like I seen in some of your vids 🤣 good luck with the build mate it already looks shit hot
Can't wait to see this build I think about 65mph to 68mph? Do u do builds for peaple because I'd love one a 1000w 48v bk wheel would do me Brill I'm 51yrs now and I want ebike cuz it's good for ur Wellbeing as I've got mentle health issues? Be nice to here from you geeze I live plymouth devon uk keep up the good work u could do this as a job 100 percent clever ain't the would for it 😂🎉🎉🎉🎉
Quick realease on the back pack , just in case o fire 🔥 …. Mind you it would lôôk kinda cool real flames flickering away like a superman cape ! Look at that dude he’s on fire 🔥 lol.
Is “stretching” a typical technique? If anyone has done this themselves how, and when did you wake up from your coma after the frame failed on your ride?
Guy Martin archived 100mph in the slipstream for a modified artic tractor unit (peddle power)... Will be interesting to see how many watts it takes for your top speed run.
@@DudeStuff LOL I have edited the above comment. (Tractor unit). If you haven't seen that episode check it out, sketchy as hell. Looking forward to pt 2 of this project 👍
This as you well know is the most powerful setup you have done yet. The power will be closer to your MT-09, I would recommend putting on your heavy armor if your doing a high speed run.
If your not going to use torque arms then don't bother using regen as the motor will rip off the rear triangle.
These QS205 are no joke, some people use them to replace boat motors and on the open sea they hit 40+ mph.
Myself I went for a QS205 5T with 200amp sabvoton and hit 30mph which is quick enough but the extra torque and acceleration is like warp speed and the hill climbs are damn good.
You gotta be careful Steve!!!
You hit that 88mph you might end up "back to the future" 😂👍🔥
😂
Hmm, I might be brave enough to try and cold set Aluminium, and then I might be brave enough to put a 5000w+ wheel on a bike…. But NO WAY I’d be brave enough to put a 5000w+ wheel in dropouts I’d just cold set!! 😂😂😂. May the force be with you!
No one seems to mention the potential of an electric shock 5000 w I mean that's going cause a cardiac arrest no ?
Fatbike frame would also be another good frame as they are a 160mm dropout! Good luck with the build dude, you will probably need a chain tensioner. Keep up the good work, good to see lewis too:)
That E Braking demo when fitting the wheel was cool.
With a 72v and 150a sab I got that motor to 67mph is a sick motor.
Yeah man the motor feels heavy untill u ride it then pulls asif it weighs nothing. I got a 20s5p molicel p42a 300ant bms bat and a 150a sabvoton fit into the triangle of a large bike with a 141mm qr boost spacing. With this 205 3.5t motor. Clean as build.
But yeah going 128v I expect mid 80s bro be careful ffs.
The Sur -Ron of this set up reaches 75 miles per hour with a 70 kilogram rider . Depends on gradient and high current draw makes battery terminal voltage dip as 26650 array cells are used . I build bicycle light batteries with the Panasonic ones .

Yeah that's what I'm talking about. That's an 8000 watt QS 273 rear hub motor and it will do well over 70 mph and that's a fact.

What's the second reason?
@@Pupenhausen If you attempt this on a alloy frame you risk breaking the welds.
I would suggest a steering damper to reduce wheel wobble.
No torque arms , are you sure it’s not just safer to put them on?
I will before using it plan to have them fabricated
Yesss! I love it! This is what I’d like to see people doing more often. We need more pev’s around in general
Here in the US, we're building hardtails doing 60mph. I've got something in the works. Currently I've hit 55.7 downhill, 52 on the flat. Others have done much better.

I lv it Steve just be careful hitting those speeds bro that's a BEAST mate
That's a tall order. I know of one right now that is a fat bike conversion to an 8000 watt QS 273 and it does over 70 mph so good luck.
YES!!! Mentioning Sam he’s a mad man!
Steve great introduction on your project.can see you buzzing over this the bike colours as they are look wicked. Can't wait for the next episode. Can see them now in ore keep the good work going .
This is going to be insane lol. Can't wait to see it flying 🤜👍
Make sure the weight is balanced and the tires can handle the speed. Bad things can happen if the tire comes apart.
Going to be crazy Steve look forward to future updates
Sam has good axels what worries me when I get up to 40mph is my quick release front wheel
This is going to be a great project!!! Steve have you done an AWD Ebike conversion on a mountain bike? Power wheels on front and back.
For spreading the dropouts on a steel frame I just use a piece of threaded rod with a couple big washers and nuts. The nuts and washers on the threaded rod pushing outward on the dropouts.
Great project, really going to enjoy watching the progress.
As someone who plans on building ebikes for people and have my own 52v 2000w hub motor. I wish the best to you!!! Hub motors are the BEST way to go!
BTW try 203m rotors BIG difference even with non hydraulic brakes.
59.9 Mph with you screaming give me more whilst risking your life! 😅
Tell us part 2 is out soon great video man 🔥😊

cut and well the frame so it can fit! its easy😦
bolt the controller on the handle bars then you have loads of space for the battery , done this with a asi bac 2000 worked well...or a rear pannier
Controller looks gd where it is. It looks factory. Cant wait to see the content on this project.

I wanna see you ride this bike cause personally, I don't think you have the cahoaney's, J.S. I don't think I would ride it.
I know it wouldn't look amazing, but why not just put a rack on the back to hold the battery and controller box.
Might need weight in the front because I think it is going to want to lift the front like a drag car.
@@paulcoinc Another battery pack!😀

Nice one Steve this should be some bike
Looking forward to seeing this one finished mate
Maybe someone could 3D print a box to fit within the frame that can hold the controller & batteries, make it all look tidy?
I like the exposed phase cable look 😄
I would be worried about the steep head angle, bike is designed to be stable for xc climbing and mellow decending, could be a tank slapper at speed pal!
Tank slapper anxiety is real lol
yes agree you dont want the dread death wobble at high speed. More weight on front wheel needed.
As a remedy, fit a 120mm travel fork. It will slack the head angle, but also move your weight rearward.
Man am looking forward to see what that ends up like I really like the look of that big controler
WooooW 125v dude that’s INSANE

He would later set several world records with his axial flux motor and bring it to market as the Lynch / Agni motor. Briggs and Stratton would eventually buy this technology which would lead to the Etek motor, which is now famous for making high speed efficient electric hot rods.
Cedric uses to achieve high speeds is by following the rules of aerodynamics, and building a bike that is as aerodynamic and as efficient as possible. The other builders on this list bypassed this step, and Cedric uses this bicycle as daily transportation on real commutes. Although this high-efficiency motor uses “old school” brushes, this fact allows builders to use very affordable controllers. He has proven his design choices through thousands of miles of commuting, and the Lynch motor is highly respected.
Cedric Lynch is known as the creator of the Agni Motor, a highly efficient electric motor that weighs around 25 pounds and can put out as much as 50hp.
Cedric Lynch is a British 'mad scientist' type mechanical engineer obsessed with the idea of greener transportation. His interest has been in building a super efficient yet powerful vehicle that can serve as a car replacement.
He started thinking of his own design for an electric motor in 1983 when he began entering competitions organized by the Battery Vehicle Society regarding building an efficient electric vehicle. At the time there was no reasonably priced DC motor with descent efficiency so Lynch decided to build his own utilizing modifying existing motors with old tin cans that he would spread out flat to use as cooling fins. Surprisingly using rudimentary materials and a garage work bench, Cedric was making better more efficient electric motors than any of the universities were able to manufacture in state of the art workshops.
Cedric then came up with a motor design that could be cheaply manufactured and began manufacturing his own motor that he could sell to the public in 1988 and the Lynch Electric Motor Company was born, known as LEMCO.
Cedric first used his motor to create a small boat called “The Spark” that would set an electric boat efficiency record. From there Cedric turned his attention to bicycles, an application generally considered too small for a lynch motor at that time. Cedric mounted his motor in recumbent bike, allowing him space to eventually use a set of thundersky lithium batteries.
The resulting aerodynamic recumbent bike had a top speed of 60mph and still managed an incredible range of 150 miles. Cedric rode his recumbent creation everywhere as a daily commuter, putting an amazing 50,000 miles on the machine - technically a motorbike.
Briggs and Stratton, the US firm famous for lawn mower engines, bought the technology and used it in their E-Tech Motor, and Cedric went on to manufacture his latest incarnation of his lynch design into the Agni motor, which is used in go karts, sailboats, motor boats, and even small airplanes.
The Lynch designed motors all have the same traits. Brushed motors, around 25 pounds in weight and they are able to put out enormous power compared to their weight. Sometimes as high as 50 hp (depending on amperage ran through the motor) at an incredible 98% efficiency. Lynch Motors are also the most often used motors in electric motorcycle racing applications.
Cedric's zero-emission motorcycle, which has a top speed of 120mph, was shown in action winning the world’s first zero carbon race - the TTxGP in the Isle of Mann.
The idea for the electric motor has been snapped up by the 56-year-old’’s friend Arvind Rabadia, who together with his brother Hasmuk Rabadia had been thinking of starting a business in India. They have now set up Agni Motors to make further-improved versions of Cedric’s motors
Despite Cedric’s breakthrough invention he has no formal engineering qualifications and taught himself the techniques needed to construct his engine. He first became interested in electrics when his parents bought him a book entitled How to build things from things found at home.
The Etek motor is a brushed 25-pound pancake shaped motor that puts out enormous power for its weight. Depending on amperage and voltage the Etek can easily provide between 15-horsepower and 30-horsepower reliably and consistently (11-kW / 22-kW). A perfect platform for a powerful electric bike if you do not mind the weight. Although brushless motors are considered more modern, a brushed motor like the Etek allows the builder to use very affordable controllers.
Cedric-Lynch invented the motor and sold it to Briggs and Stratton which US company produced the Etek at a lower price (around $600). In the late 90’s early 2000’s it was the way to go for a high-power / light-weight electric vehicle. Many small E-vehicle records were set using the Etek motor. Finally, the market had a relatively lightweight and powerful electric motor available to the masses.
In essence, the Etek allowed hot rodders to build electric bikes. Before the Etek very few people had ever achieved 50mph on an electric bike. Even today, Etek motors (and newer incarnations of the Etek motor) are used to make some super fast electric bikes. In the case of Liveforphysics, the fastest E-bikes ever.
Liveforphysics used a newer version of the Etek (the Agni motor), to achieve speeds of over 70mph, and dominate a recent hill-climb event.
Every Etek I have ever ridden has been characterized by brutal off-the-line acceleration, usually to a point where you have to apply the throttle very carefully or get thrown off. However, it is possible to run an Etek at a lower voltage or lower amperage and have a very manageable, safe, and sane electric bike that will not burn out on you, no matter high steep the incline.
best of luck with your build. I love to see a powerful ebike. There are only a few frames i'd feel confident in stretching and a halfrauds voodoo isn't one of them. but, hey - you gotta try it and push the limits.👍 life would be boring otherwise
Why what’s wrong with voodoo ?? I have two of them they’re alright ??
They're OK they just don't normally do 70 ish straight from Halfords 😂
@@DudeStuff hahaha yeah I see what you mean now 🤣
Vantastic job Pitbull.Do you want to modify my 26" Mountain bike? I have duel suspension and the best thing,it's brand new.If I can get up around 35 mph that's all I want. Nothing radical like your beast, ha. Looking forward to the next video for real.Keep up the good work.Your a natural. I'll keep watching! Craig T.
Thanks mate appreciate it. I don't really get any time to do other people's bikes to be honest crazy busy all the time now 🙃
good luck on that frame...
Fastest death trap 😂
Mad like 62.7mph
man looks sick reminds me of back to the future car with the controller there and all the wires to it cant wait :)
Ive got a giant mountain bike would appreciate a bit of advice on how i convert please 🙏.
Not sure if you call them nuts across the pond but we can all get a little too excited about a nut, so I don’t blame you. But that’s a bolt over here.
Looking forward to this one.
For that sort of speeds it needs suspension.
"Because we like tight nuts" 😂
What brand is your shacket mate, really like it? Thanks for uploading and sharing 👍
Dude, all that stuff on the jits matt's.
Dude this build is organic and beautiful 🤘🏻🤡🤘🏻 stoked
The UK's Dr Emmet Brown. I will whack a guess in and say all being well, you'll get 75.6 mph. Good man 🚴♂️💨💨
Hi mate does adding a device to increase the speed on a whyte mid drive e bike put the motor or battery at risk cheers
Any riding can put the motor or controller at risk if you push it to hard for too long. Couldn't say for sure but most factory ebikes are restricted for UK law I doubt unlocking them to their normal potential would pose much risk on the components. A lot of mid drives are 750w restricted to 250. That's not to say any old dodgey3rd party plug in device is safe
Ive got the bright orange voodoo hoodoo please dont disrespect lmao
my guess is that the hub motor weight is about 10-15 kg :D and batterybackpack is a baaaad idea, discovered by myself in a crash the bike CG is way of.
its around 13 or 14kg
Be careful about what Mah lipos you use, too small of a capacity and they wont handle the amps your after. I tried it with some 9000mah lipos using 4, 4S in series and couldnt ask for more than 50amps before lipos where getting hot. If you used the 20000mah turnigy lipos you might have better chance of success
Turnigy been out of stock for ages. Ran 100a sabvoton fine for half hour didn't get hot will just see how it goes
@Dude Stuff hobbyking have them in stock you just have to order them all separately. Otherwise, you end up paying stamp duty
@Kevin porter been checking for a year last month I saw them back in stock but they can no longer ship 6s to UK
I love the stretching but how do you guarantee it’s still centralised?
There's no guarantees with anything on this build just going to make it work 😃
@@DudeStuff should be fun for sure, is the dropout wider on a fat bike?
@vdubster probably around 160mm on this now I think fat bikes might be around 190
@@DudeStuff I’m aiming to go fat bike, hard to decide whether to buy one and convert.
Looks ok
As far as numbers go the math says u should be doing 100 mph I do 75 on a 150 sab on an enduro frame
im guessing Voodoo aint gonna honour any warranty issues
I can't wait to see this going
Just make sure you wear some good safety gear when you get this beast finished steve not the flip flops like I seen in some of your vids 🤣 good luck with the build mate it already looks shit hot
Can’t wait to see this go 😊
Can't wait to see this build I think about 65mph to 68mph? Do u do builds for peaple because I'd love one a 1000w 48v bk wheel would do me Brill I'm 51yrs now and I want ebike cuz it's good for ur Wellbeing as I've got mentle health issues? Be nice to here from you geeze I live plymouth devon uk keep up the good work u could do this as a job 100 percent clever ain't the would for it 😂🎉🎉🎉🎉
they tyres will not last at that speed , will they ?
Quick realease on the back pack , just in case o fire 🔥 …. Mind you it would lôôk kinda cool real flames flickering away like a superman cape !
Look at that dude he’s on fire 🔥 lol.
Dude 5k is allot, my bbshd at 58.8v 30 amps feels already powerful.
Is “stretching” a typical technique? If anyone has done this themselves how, and when did you wake up from your coma after the frame failed on your ride?
Hi mate im new to the channel just subscribed. Debating converting my cannondale to a 2000watt hub. Any recommendations on hubs and battery's
So what does the wheel weigh?
This video has to be shared 👌
Absolutely bonkers riding high-speed on A stressed frame at high speed. Balls out totally.
Guy Martin archived 100mph in the slipstream for a modified artic tractor unit (peddle power)... Will be interesting to see how many watts it takes for your top speed run.
Not sure what an Arctic tracker is but love Guy Martin. Hopefully get a decent speed no slipstream or trickery
@@DudeStuff LOL I have edited the above comment. (Tractor unit). If you haven't seen that episode check it out, sketchy as hell. Looking forward to pt 2 of this project 👍
