I think it is good that you do your videos just in a corner of a room in your house, while sitting on the floor. It dispels the myth that one needs a big shot full of tools and lots of skill to do one of these conversions.
I know that this video is some 18 months old, but having found it a few months ago, it became my inspiration to get off of my butt and sort my bike out! I have a Marin Palisades Trail SE 29ER, which has sat in the garage for the last 4 year, as I was unable to ride due to health issues, having found this channel and this video, I decided to have a go at turning it into an E-Bike, and by following this tutorial I have done just that, boy what a difference this has made for me, I can now go out riding every day and I'm really enjoying the outside world again. Thanks Johnny....
Hi , just done an install on my own bike, using this video as my guide. It worked perfectly so thanks for the guidance. Just waiting on gear shift sensor and hydraulic brakes sensor to finish it off.
I live in Hawaii and appreciate your knowledge. E-Bikes are taking off here and are creating quite a stir! Hawaii has the highest cost of living anywhere on earth! Ever get tired of the rat race, we really could use a guy like you ! Mahalo for this VALUABLE info! Aloha!
Jonny - took your advice and converted my Cannondale, F3 Caffeine to Bafang BFHD (local dealer); your excellent guidance and visuals were most helpful, I added a heavy duty motor bracket and installed hot shrink tubing over the connections; other than that, your instruction expertise and effort made the difference - thank you!
Johnny; just so you know, I have kids senior to you so, when I say your teaching skills are highly developed, I mean you are superbly skilled at your trade and extremely succinct in your presentation. Being older, I needed someone who knows how to teach. I'm gonna need a quality power system this year for my fat tire mongoose. I like to hunt and in my home state of Alabama I must use state lands. Cant afford a hunting club. Some if these wildlife areas are rather vast. Terrain is usually flat or rolling hills. Some over the top steep. Autos are not allowed beyond certain limits but bikes are allowed. Well, it's kinda fun to take up bike riding in my late 60's but I'm gonna help. I'm gonna save your videos so that when I've saved up enough to get the conversion kit I'll have you to turn to. Thank you sir. Your a good man. Respectfully, Sergeant Frank Davis, Army retired.
I just recently converted two 2019 Trek Dual Sport 2's. The kit fit almost too perfectly. Very happy with our Bafang kits. Thanks for your vid. Have enjoyed watching this system installed on different brands and styles of bikes and how everybody does things a little differently.
I purchased my mid-drive kit from Johnny and followed his video...I had to watch it a few times but I got it done! I have a Schwinn Midtown bike which has a curved downtube...Johnny recommended getting a Triple Bob plate with rubber coated hose clamps ...which made it possible to attach my downtube battery...Learned a lot from the experience which includes NOT breaking the chain if not needed...Thanks Johnny!
Almost made a mistake and bought a hub drive ebike, so glad I saw Johnny nerdouts video on HUB Drive vs mid Drive. Now building my own! Johnny you da man!!!!!
I did my install over the weekend pretty much following this video. I just changed the order a little. Everything came out great. If there is one thing I would say to others it's: If you are going with an aftermarket chainring with an offset to bring the chain line back over, put the chainring on the motor BEFORE shimming the motor and tightening things up. The shims needed to move the motor away from the chainstay may not be enough to allow an offset chainring to clear. Well, in my case anyway. I went with a 42T Luna Eclipse on a Growler Stout fatbike. I had to remove the motor and add a couple more shims. Then add some more shims on the bracket bolts.
You're lucky to have found the 42T Luna Eclipse... they are out of stock and I need one on my new build, unless I just limit the rear cog to a couple gears. Painful to find this out after the build, I couldn't wait to use the new ebike. Hopefully Luna will get more Eclipse, as far as I can tell, there's not another better/easier solution.
@@Hiker_Mike I do have a problem with a couple gears under electric power. Sometimes the chain clicks and jumps a gear. No matter how much adjusting I do. But it's a 12 speed, so I sort of expected it.
Hello Johnnynerdout, tham you so much for the video. You mentioned around 5:00 that you made a video about using an angle grinder to remove a crank arm with stripped threads. I cannot find this video, can you please share the link? Thanks appreciated
Excellent tutorial, thank you! Wish I had seen this one a few years ago when I assembled. Resolving unexpected Chain line issues was a bugger. At > 1000 of miles, BBS02 running strong, no issues.
Thanks John, I've done 2 bikes now, a conventional Specialized and Rans recumbent. I love riding the recumbent, it is so fast now, up to 40mph and up to 70 miles but not both at the same time. Speed kills the battery but wow it's fun. I generally like riding at PAS 4 of 9 and hold about 22 mph. The e-kit removes the hills and reduces the effects of wind. I did have to make a special battery mount for the battery, hanging it under the bike. Thanks for promoting how easy this is to do.
I love this video so much I swear lolll, super helpful with all sorts of problems and a bit humorous instead of the dead people you usually find. Thank you so much.

Super stoked all the parts for my 750w mid drive befang finally arrived and installed flawlessly thanks to your help and information. next will be my pull behind trailer with dog box, solar charger, second battery and possibly a 3rd wheel generator since ill be pulling the weight mighht have it help out. Thanks again and some pictures may be comming.
Great video. While the workspace was small, the white background made it easy to follow along. The camera was nice and close, and the audio is clear. Best install vid I've found... Thank you for sharing!
Hey thanks! Sometimes I get knocked for not doing it in a proper bike shop, but personally I feel like it shows that anyone can do the install anywhere 😀
Thanks for you last comment. I am looking at doing a conversion with a similar befang model. Do you think a bike with cables is easier or hydroloc for a first time builder. I have already bought the bike now but was just wonder if my thoughts where right
I went to a clients house to do a bid on some tree care and he let my wife and I try his e-bike he built himself and holy smokes! that self assist pedaling is too much fun! I look forward to buying a conversion kit from you. Thank you so much for putting together this video.
Brilliant help with really clear presentation. Well done and thanks for the tutorial. One thing that would be nice is to see how hard it would be to resize those long cables. Cheers.
Thanks John, nice presentation. Added Tip: Rotate the cut zip-ties inward and against the frame because they can be sharp and pointy against your bare legs if you ride in shorts or hands when loading/off loading the bike.
This is awesome. You deserve a better space to do this work. Thank you for your service! In addition to the cost of the parts for conversion, I would also have to invest in some tools. The upside is that I am not sure I would stop at one conversion. Unfortunately, Mr. Murphy would also want to join me for the ride. The cable management looks like a huge job.
Precision piece of kit they are , he hasn't built those 200 conversions with that, still has its to clean non bent look, best part is the analogue click sound you get to make every time you use it AvE style , rofl, perfect results every time, 14:29 free "all-in-one brake sh1t" too 14:29 ;-]
Told myself never to troll but you but you beat me to it! So frustrating to see the so called experts jacking up their tools missusing them! Ughhh so frustrating! Torque arm wrenches are so junk after one build anyhow so may as well be a spring breakerbar!! Lol!
The most important thing when considering buying this Bafang mid drive is that the bottom bracket has to be in the 68 to 73mm range, which is quite common.
What a wonderful opening you did in the video. Exactly how I feel - * big smile ! I haven't watch the whole video yet, as I write this, my gut tell me that I will like it even though only 3:30 in. Peace!
Hey mister Nerdout! Thank you for the fine tips! I hate he ridiculous excess cables spaghetti, so it a good idea to cut them and solder so that the whole installation is neater?
Great video. It was nice to finally see someone addressing the wiring and trying to neaten things up. I think I better order some more blue zip ties ;)
I watched a few tutorials, but only yours really went over the plug situation the best way. It was you video on converting a mongoose dolomite that introduced me to your channel and led me to buying a triangle battery and 1000w motor. My bike is so heavy now 😅 its a tank
Hey Johnny, this is hands down the best install video I have found to date. In Melbourne Australia and completed my install start to finish with this video (watched it about 20 times and rewatched sections as needed). Thanks so much. Hoping you could help with one issue (or it may be a good video suggestion for the future), I have installed the 1000w 52v kit on a brand new bike. Swapped out the chain ring for a Lekkie 42t. I'm using the chain that came with the bike which originally had a 36T chain ring. The issue I'm having is the chain slips/pops in high gear when I'm applying heavy load (like taking off or gaining speed before an uphill climb). Everything seems to be aligned correctly, all new parts but I'm kinda lost as to the cause. Could the chain be too long for the kit? (given that the chain ring size increased this may not be it)... or is it one of those deceptive solutions where it's actually that the chain is too short. Dunno, but hoping you could help. If you see this comment or not, no sweat. You're still a bloody legend!
Hey Marco , If I were you I would get a new chain installed that's the appropriate lenght for that lekkie 42 tooth once you get a new chain installed take it for a test drive without the assistance of the motor and see if it jumps gears. If it does take a look at your chain line. Also, stick with bike manufacturers chain , if the chain is shimano buy shimano. Cheers.
Lefty loosey, righty tighty is for normal threading, not for left or right hand threads. I'm not aware of any saying that covers right vs left hand threads. Good video!Thanks!
The top of the line specialized e-bike in Massachusetts is 12 grand. I just put a bbs02b on my 1998 aluminum trek Y. 500c computer is great. Get a comfy seat. So much better for going 40 miles in a day. No way that tiny specialized battery will go 40 miles.
I’m getting the parts together for my conversion and watched this video as prep work. 10/10 - everyone who makes DIY videos should be more like you So excited to get started!
when mounting the battery rail I lightly oil the under face of the rail, clean the downtube with rubbing alcohol (or whatever) and then apply some 2K polyester resin (stuff used to fix car bodys) on the downtube, then screw down the rail. The oil will keep the polyester from sticking to the rail. The hardened polyester gives the rail a perfect fit on the frame and prevents it from wobbling with vibrations and impacts.
@@BarMagnet yes, cling film or thin plastic film works. I now use it to prevent the modelling clay from sticking to the downtube so I can remove it without damaging the clay before baking
@@JoLe1991 @JohnnyNerdOut There's also an excellent idea from one of your commenters Jonas Léchot on this video. I think a combination of triple bob @ Ebikes.ca and Jonas Léchot would be a great solution. The jubilee clips (ultimately with heads ground off to prevent theft) are necessary.
I just converted my fat tire using a Bafang 1000 watt mid-motor. Watching this video gave me answers on the speed sensor and another issue with a combo shifter/brake.
Just some feedback, I ended up damaging my wire as I brought in under the motor as you mentioned. If not much space or anything sharp (if wires running inside and coming out from there) - avoid getting the cables from between motor and the the place it is instered intro the bike.
9:29 - Wires are absolutely not, "just metal." The problem here is not metal being bent. Copper wires like this are designed to be able to have a very tight bend. They have very fine strands which withstand lots of tight bending very well. The problem is the insulation. If you pinch these wires the metal is stronger than the insulation and will mash the insulation so that the various individual wires within the cable will short out. This can completely ruin a cable while leaving it looking almost fine on the outside. This is incredibly hard to troubleshoot later.
With that much experience, perhaps you are able to diagnose my problem which is NO PAS after just 3600kms of riding? My throttle still works fine but tends to overheat my motor. Rotating my pedals drives the chain and rear wheel but does not engage the PAS. My motor is a Bafang BBS02B 500w 36v mid-drive on a recumbent trike. The speed sensor has been replaced and works ok.I have dismantled the motor but nothing seems to be obviously broken or out of the ordinary.
Hi Johnny, I'm glad I found you! Excellent videos, your tutorial is really useful ! I have this same bike, a 29" Schwinn Axum DP but in medium size that I would love to convert to an e-bike with the same Bafang motor My first question is about the offset in the chainring. What is the model of the Lekkie chainring you used in this video? What is the exact chainring "offset" in millimeters for this motor and this bike that you used in this tutorial to have that perfect chainline in this bike? If possible, I would like to stick to 30T and a narrow-wide tooth pattern. Stock tires, I upgraded to an air fork, hidraulic brakes and to a groupset Advent X 10sp 11-48/30T. I'll be riding mostly PAS at an avg speed of 7 to10 mph, top speed 20 mph in some segments, winds
I have a very similar bike from Schwinn, 30T chainring. No upgrades yet. I'm considering the 750W motor. To keep it legal and still capable. The bike is a 1x7 speed mountain bike. 29". I would also want to find out what chainring should I use, is 44T too much? Many kits will have that or bigger... I would also like to get crack arms 165mm too, to help with the knee bending. Please let me know if you have some information about it. I will share what I find too.
@@EliseoCorrales Hello Eliseo, and yes indeed, I have already successfully (thanks Johnny!) converted my Axum DP 29" with the BBS02. Do you speak Spanish? Because if you want to know about my experience, for me it will be easier in Spanish, Specially in regards of some "chainline" issues that you need consider.
Dear Jonny, I have ordered my kit following your recommendation. My bike is a ten speed mountain bike which has two gear shifters one on the left hand and one on the right. The left ends lets you choose between two options to go up steep terrain as well as normal cycling. The one on the right gives you 5 gear options. My bike also has a derailer which I assume I will need to remove? Can you advise. Thank you so much for your brilliant explanation which I have now watched a several times. Many thanks Andrew
You're going to need to lose the left gear shifter. The front derailleur that's controlled by the left shifter also needs to go. Your 10-speed bike just became 5-speed, with an electric power boost.
thanks , nice layout of the video details, I'm in the last stages of my install and have 2 connections left coming from the BBSHD unit, a red/black set, and a yellow cable, I'm assuming the yellows are generic port connections and maybe my extra one would be used for shift/gear sensor?, and maybe the red/black is the exterior light you mention. any way hope so I am very excited about this feeling!!!
Johnny that was awful...cable brakes..have you got suicidal tendencies..you didn't show how to fit the speed shifter cut off switch installation.. you didn't show the light switch and brake light installation ...the cable installation was diabolical and dangerous..no final testing of your fine mechanical technical prowess. Please Johnny make another video and do it properly... 🙏😫 and maybe a video on how to flash the motor settings and all the setting up procedures on the program screen...it was a bad title to choose...complete e bike conversion tutorial ....you can do alot better Johnny ..
Where is your link to a complete e bike conversion? I really think you should post it so we all can go to the grand wizard of everything and see how perfect you really are and please educate us on the speed shifter cut off switch because I have never heard of it? I know there is a speed sensor which Johnny did show and then said to go to the video of the shift sensor, but yeah he didn't mention anything about a speed shifter cut off switch probably because there is no such thing! Waiting for you link to teach us all!
The title of the video is I decided to call it complete e bike conversion tutorial .what's the difference??? So I left the word Bafang ..so what..what does it change!!!!! Word Nit picking won't change the narrative's and as for speed shifter cut off switch installation ....I will reword it correctly for you.. its a linear mechanical sensor cut off switch...you know the bit that goes on the cable for the derailleur to kill the juice to the motor to avoid chewing up the gears when your selecting them...personally it works great with my Archer DX1 trial...as for the grand wizard bit...keep your sarcastic comments to yourself...I watched this video with numerous pals and we all had a good laugh showing his builder bottom antics working on his knees instead of putting it on a bike stand. Nevertheless I like Johnny's approach no nonsense approach...but from a engineers point of view
@@patrickbonin137 Most of the people coming to these videos don't have fancy shops or equipment nor do the ones taking there time to post in an effort to help. I couldn't wait for the title throw though! You are an Engineer and that was the best laugh I had all week! Thanks! Here are some of your degrees finest moments in history... ua-cam.com/users/results?search_query=engineering+disasters+full+episodes ENJOY!
I think your comment is unfair Patrick. Johnny has helped many of us with his videos and prompt replies. As he said he has converted 200 bikes. I take this video as a general guide if you have just bought a Bafang kit, he does have another video as he said and I have watched that shows the gear selector sensor install. This video would be too long if it was to show gear selector install, brake adjustment, gear indexing, etc. If you have ever filmed, edited and uploaded any videos which your channel has none, then you would appreciate the time taken to produce such content and it's free.
These videos will NEVER show every possible thing on can do. For that go to Lunacycles website and read the Forums. There are complete builds step by step. Also custom install/ build like mine on there. Give this guy a break. It was pretty well done IMO. Anyone wanting MORE info SHOULD have to do some research THEMSELF.
Awesome instructional. Just converted old Schwin stingray However there were no brakes in the package. The bbshd only goes for a bit before cutting out. I hope it’s due to brake cutoffs not installed yet.
For the people in the future, please buy his tools. It doesn’t have to be from him, but get the exact ones he recommends.

Super stoked all the parts for my 750w mid drive befang finally arrived and installed flawlessly thanks to your help and information. next will be my pull behind trailer with dog box, solar charger, second battery and possibly a 3rd wheel generator since ill be pulling the weight mighht have it help out. Thanks again and some pictures may be comming.
Great video. While the workspace was small, the white background made it easy to follow along. The camera was nice and close, and the audio is clear. Best install vid I've found... Thank you for sharing!
Hey thanks! Sometimes I get knocked for not doing it in a proper bike shop, but personally I feel like it shows that anyone can do the install anywhere 😀
Thanks for you last comment. I am looking at doing a conversion with a similar befang model. Do you think a bike with cables is easier or hydroloc for a first time builder. I have already bought the bike now but was just wonder if my thoughts where right
So sorry, I just saw this comment now! In case you still are looking for a response 🫠 cable is easier. 👍
This is freaking brilliant. Thanks man! Hoping to turn my beloved 90s bike into an e bike.
Just finished installing a 500w on a 2006 Specialized Rockhopper. Thank you very much 🙏
Dude you’re a beast! Thank you so much for taking the time to make this video. Your humor is great. Keep it up. You’re blowing up!
Thanks!
You sir are the Bob Ross of e bikes, thank you for your guidance. 😊
I went to a clients house to do a bid on some tree care and he let my wife and I try his e-bike he built himself and holy smokes! that self assist pedaling is too much fun! I look forward to buying a conversion kit from you. Thank you so much for putting together this video.
Brilliant help with really clear presentation. Well done and thanks for the tutorial. One thing that would be nice is to see how hard it would be to resize those long cables. Cheers.
Great video, I'm buying a bafang very soon and this video helps a lot with installation.Thanks from the UK.
Thanks John, nice presentation.
Added Tip: Rotate the cut zip-ties inward and against the frame because they can be sharp and pointy against your bare legs if you ride in shorts or hands when loading/off loading the bike.
Good tip.
I cut zip ties flush with a micro cutter like the harbor freight PITTSBURGH 5 In. Micro Flush Cutter.
Can cut flush with side cutters if you know how ;-)
@@hopsriderV yeah, still unsightly and potentially a skin cutter... So, turn em in.
Nail clippers for the win!
very educational while being enjoyable to watch. gives me encouragement to do a diy project
i would say to you Johnny it was fantastic explained and you didn't go sort cut well done thank you very much.
You are the only one spent time to explain the cable management
Nice going! I’ll be watching this one a few times.
I don't just watch this video. I study it. Nice work, John.
Never use torque wrench for undoing bolts! Other than that - great video. Expecting my motor/parts this week.
This is awesome. You deserve a better space to do this work. Thank you for your service! In addition to the cost of the parts for conversion, I would also have to invest in some tools. The upside is that I am not sure I would stop at one conversion. Unfortunately, Mr. Murphy would also want to join me for the ride.
The cable management looks like a huge job.
5:58 you should never use a torque wrench to break threads loose.
LOL I came below to say exactly that... no true engineer would commit such a sin.
Probably not but it is a cheap torque wrench, so what the hell.
Precision piece of kit they are , he hasn't built those 200 conversions with that, still has its to clean non bent look, best part is the analogue click sound you get to make every time you use it AvE style , rofl, perfect results every time, 14:29 free "all-in-one brake sh1t" too 14:29 ;-]
A cheap steel bike post makes a decent socket-extender-breaker-type-thing.
Told myself never to troll but you but you beat me to it! So frustrating to see the so called experts jacking up their tools missusing them! Ughhh so frustrating! Torque arm wrenches are so junk after one build anyhow so may as well be a spring breakerbar!! Lol!
This video helped me prepare for neurosurgery because I have lots of zip ties and cable management is key. 👍
The most important thing when considering buying this Bafang mid drive is that the bottom bracket has to be in the 68 to 73mm range, which is quite common.
Not true they make for fat tire bikes. All the way to 120 mm
Not true they make for fat tire bikes. All the way to 120 mm
Ya, there are 120mm full fat versions.
What bafang motors are the definite choice considering i have the common bracket?
The bottom bracket on my bike is 67. Will this still work? Can I use washers?
What a wonderful opening you did in the video. Exactly how I feel - * big smile ! I haven't watch the whole video yet, as I write this, my gut tell me that I will like it even though only 3:30 in. Peace!
This was great, and you made it look completely doable. Bafang should pay you for this, nice work!
We need more people on UA-cam like that thank you😅
Hey mister Nerdout! Thank you for the fine tips! I hate he ridiculous excess cables spaghetti, so it a good idea to cut them and solder so that the whole installation is neater?
Thanks for this video. I successfully installed a Bafang mid drive on my mountain bike. Works great. Love it!
dude! I bet this took so long to do! Thanks so much!
Any time!
Just fitting a bafang mid drive, lots of advice on this video, thanks from n Wales UK
Great video. It was nice to finally see someone addressing the wiring and trying to neaten things up.
I think I better order some more blue zip ties ;)
I watched a few tutorials, but only yours really went over the plug situation the best way. It was you video on converting a mongoose dolomite that introduced me to your channel and led me to buying a triangle battery and 1000w motor. My bike is so heavy now 😅 its a tank
Must be the steel mongoose then! Svelt is not it’s strong suit but it will survive a hurricane
@@JohnnyNerdOut its held up well so far. Rode it to and from work all winter long. Through snow storms and all. Still going strong
Excellent vid, you’ve inspired me to build a mid drive, cheers!
Excellent video, thanks so much. I'm in the process of converting Schwinn Axum right now and it has been very helpful.
Hey Johnny, this is hands down the best install video I have found to date. In Melbourne Australia and completed my install start to finish with this video (watched it about 20 times and rewatched sections as needed). Thanks so much. Hoping you could help with one issue (or it may be a good video suggestion for the future), I have installed the 1000w 52v kit on a brand new bike. Swapped out the chain ring for a Lekkie 42t. I'm using the chain that came with the bike which originally had a 36T chain ring. The issue I'm having is the chain slips/pops in high gear when I'm applying heavy load (like taking off or gaining speed before an uphill climb). Everything seems to be aligned correctly, all new parts but I'm kinda lost as to the cause. Could the chain be too long for the kit? (given that the chain ring size increased this may not be it)... or is it one of those deceptive solutions where it's actually that the chain is too short. Dunno, but hoping you could help. If you see this comment or not, no sweat. You're still a bloody legend!
Hey Marco , If I were you I would get a new chain installed that's the appropriate lenght for that lekkie 42 tooth once you get a new chain installed take it for a test drive without the assistance of the motor and see if it jumps gears. If it does take a look at your chain line. Also, stick with bike manufacturers chain , if the chain is shimano buy shimano. Cheers.
Lefty loosey, righty tighty is for normal threading, not for left or right hand threads. I'm not aware of any saying that covers right vs left hand threads. Good video!Thanks!
The top of the line specialized e-bike in Massachusetts is 12 grand.
I just put a bbs02b on my 1998 aluminum trek Y. 500c computer is great.
Get a comfy seat. So much better for going 40 miles in a day.
No way that tiny specialized battery will go 40 miles.
Same I got a bbso2 on a little carbon folder. Pulls me up a steep hill no prob.
thanks....that bottom cable bundle is a weird design feature.....why doesn't the motor have a bundle box built in?
I’m getting the parts together for my conversion and watched this video as prep work. 10/10 - everyone who makes DIY videos should be more like you
So excited to get started!
Totaly agree with the pc bit iv been a pc builder for over 30 years now and went the same way with building cycles and ebikes in UK
when mounting the battery rail I lightly oil the under face of the rail, clean the downtube with rubbing alcohol (or whatever) and then apply some 2K polyester resin (stuff used to fix car bodys) on the downtube, then screw down the rail. The oil will keep the polyester from sticking to the rail. The hardened polyester gives the rail a perfect fit on the frame and prevents it from wobbling with vibrations and impacts.
updated method: making adaptor plates with heat hardening modelling dough (FIMO).
Cling film? I'm terrified to depend on oil.
@@BarMagnet yes, cling film or thin plastic film works. I now use it to prevent the modelling clay from sticking to the downtube so I can remove it without damaging the clay before baking
@@JoLe1991 @JohnnyNerdOut There's also an excellent idea from one of your commenters Jonas Léchot on this video.
I think a combination of triple bob @ Ebikes.ca and Jonas Léchot would be a great solution. The jubilee clips (ultimately with heads ground off to prevent theft) are necessary.
I just converted my fat tire using a Bafang 1000 watt mid-motor. Watching this video gave me answers on the speed sensor and another issue with a combo shifter/brake.
Its 3am, do you where the bike nerds are? Yep, you guessed it, watching your channel, lol. Johnny, great mid-drive install video. Thanx!
As a lifelong master mechanic I can say yes to quality tools.
Just some feedback, I ended up damaging my wire as I brought in under the motor as you mentioned. If not much space or anything sharp (if wires running inside and coming out from there) - avoid getting the cables from between motor and the the place it is instered intro the bike.
You make it look easy. Thanks a bunch! I saw your video about staying away from hub motors. After seeing this video I'm sold.
9:29 - Wires are absolutely not, "just metal." The problem here is not metal being bent. Copper wires like this are designed to be able to have a very tight bend. They have very fine strands which withstand lots of tight bending very well. The problem is the insulation. If you pinch these wires the metal is stronger than the insulation and will mash the insulation so that the various individual wires within the cable will short out. This can completely ruin a cable while leaving it looking almost fine on the outside. This is incredibly hard to troubleshoot later.
With that much experience, perhaps you are able to diagnose my problem which is NO PAS after just 3600kms of riding? My throttle still works fine but tends to overheat my motor. Rotating my pedals drives the chain and rear wheel but does not engage the PAS. My motor is a Bafang BBS02B 500w 36v mid-drive on a recumbent trike. The speed sensor has been replaced and works ok.I have dismantled the motor but nothing seems to be obviously broken or out of the ordinary.
Great vid. Installed on a Roll Sport!
@MacGyver303030 I'm going to put on a 2021 Roll Elite, can you share some of the components you chose, chain ring etc?
25:42 what is "this" called and what does it do?
You're a legend and I owe you a beer. Thank you
HAHA, I'll take one!
Excellent guide. Had install done quicker than expected by referring to this video,
Great to hear!
Hi Johnny, I'm glad I found you! Excellent videos, your tutorial is really useful !
I have this same bike, a 29" Schwinn Axum DP but in medium size that I would love to convert to an e-bike with the same Bafang motor
My first question is about the offset in the chainring. What is the model of the Lekkie chainring you used in this video? What is the exact chainring "offset" in millimeters for this motor and this bike that you used in this tutorial to have that perfect chainline in this bike?
If possible, I would like to stick to 30T and a narrow-wide tooth pattern. Stock tires, I upgraded to an air fork, hidraulic brakes and to a groupset Advent X 10sp 11-48/30T.
I'll be riding mostly PAS at an avg speed of 7 to10 mph, top speed 20 mph in some segments, winds
Took all that time to ask nice questions to get no response. Nothing but crickets.
@@theone2be33 🤣
I have a very similar bike from Schwinn, 30T chainring. No upgrades yet. I'm considering the 750W motor. To keep it legal and still capable.
The bike is a 1x7 speed mountain bike. 29".
I would also want to find out what chainring should I use, is 44T too much? Many kits will have that or bigger... I would also like to get crack arms 165mm too, to help with the knee bending.
Please let me know if you have some information about it. I will share what I find too.
@@EliseoCorrales Hello Eliseo, and yes indeed, I have already successfully (thanks Johnny!) converted my Axum DP 29" with the BBS02. Do you speak Spanish? Because if you want to know about my experience, for me it will be easier in Spanish, Specially in regards of some "chainline" issues that you need consider.
Awesome video - got me through installing my e-bike kit on a Babboe City Cargo bike!😄
Thank you Johnny!
👍
thanks Johnny. building my own cargo bike. now its Gunna be an electric cargo bike👌
Dear Jonny, I have ordered my kit following your recommendation. My bike is a ten speed mountain bike which has two gear shifters one on the left hand and one on the right. The left ends lets you choose between two options to go up steep terrain as well as normal cycling. The one on the right gives you 5 gear options. My bike also has a derailer which I assume I will need to remove? Can you advise. Thank you so much for your brilliant explanation which I have now watched a several times. Many thanks Andrew
You're going to need to lose the left gear shifter. The front derailleur that's controlled by the left shifter also needs to go. Your 10-speed bike just became 5-speed, with an electric power boost.
I've done my Batavus Traversa with 7 speed Nexus rear. It flies!
I'm finding that , like origami, cable management is an art/science.
Dude, you are seriously the freaking man.
😎😀
@@JohnnyNerdOut I've been bingeing on your vids. Did I hear you say you live in portland?
@@al-du6lb used to. Probably one day again
@@JohnnyNerdOut What state are you in now?
@@al-du6lb Utah
Great stuff!
that is a good looking mid drive you got there how much it cost to get one
The 750w version starts around $415. The 1000w starts around $600
Never use a torque wrench as a breaker bar... I know you’re just working on a bike, but it makes the wrench less accurate when tightening to spec.
Good tip
His torque wrench is so crappy doubt it really is calibrated anymore.
Dude! You just gave me the confidence to tackle this! Thanks
Me speak good.. subbed 😎
thanks , nice layout of the video details, I'm in the last stages of my install and have 2 connections left coming from the BBSHD unit, a red/black set, and a yellow cable, I'm assuming the yellows are generic port connections and maybe my extra one would be used for shift/gear sensor?, and maybe the red/black is the exterior light you mention. any way hope so I am very excited about this feeling!!!
Johnny that was awful...cable brakes..have you got suicidal tendencies..you didn't show how to fit the speed shifter cut off switch installation.. you didn't show the light switch and brake light installation ...the cable installation was diabolical and dangerous..no final testing of your fine mechanical technical prowess. Please Johnny make another video and do it properly... 🙏😫 and maybe a video on how to flash the motor settings and all the setting up procedures on the program screen...it was a bad title to choose...complete e bike conversion tutorial ....you can do alot better Johnny ..
Where is your link to a complete e bike conversion? I really think you should post it so we all can go to the grand wizard of everything and see how perfect you really are and please educate us on the speed shifter cut off switch because I have never heard of it? I know there is a speed sensor which Johnny did show and then said to go to the video of the shift sensor, but yeah he didn't mention anything about a speed shifter cut off switch probably because there is no such thing! Waiting for you link to teach us all!
The title of the video is I decided to call it complete e bike conversion tutorial .what's the difference??? So I left the word Bafang ..so what..what does it change!!!!! Word Nit picking won't change the narrative's and as for speed shifter cut off switch installation ....I will reword it correctly for you.. its a linear mechanical sensor cut off switch...you know the bit that goes on the cable for the derailleur to kill the juice to the motor to avoid chewing up the gears when your selecting them...personally it works great with my Archer DX1 trial...as for the grand wizard bit...keep your sarcastic comments to yourself...I watched this video with numerous pals and we all had a good laugh
showing his builder bottom antics working on his knees instead of putting it on a bike stand.
Nevertheless I like Johnny's approach no nonsense approach...but from a engineers point of view
@@patrickbonin137 Most of the people coming to these videos don't have fancy shops or equipment nor do the ones taking there time to post in an effort to help. I couldn't wait for the title throw though! You are an Engineer and that was the best laugh I had all week! Thanks! Here are some of your degrees finest moments in history... ua-cam.com/users/results?search_query=engineering+disasters+full+episodes ENJOY!
I think your comment is unfair Patrick.
Johnny has helped many of us with his videos and prompt replies. As he said he has converted 200 bikes.
I take this video as a general guide if you have just bought a Bafang kit, he does have another video as he said and I have watched that shows the gear selector sensor install.
This video would be too long if it was to show gear selector install, brake adjustment, gear indexing, etc.
If you have ever filmed, edited and uploaded any videos which your channel has none, then you would appreciate the time taken to produce such content and it's free.
These videos will NEVER show every possible thing on can do. For that go to Lunacycles website and read the Forums. There are complete builds step by step. Also custom install/ build like mine on there. Give this guy a break. It was pretty well done IMO. Anyone wanting MORE info SHOULD have to do some research THEMSELF.
Awesome instructional. Just converted old Schwin stingray However there were no brakes in the package. The bbshd only goes for a bit before cutting out. I hope it’s due to brake cutoffs not installed yet.
Much appreciated good sir. My life is changed forever.
Hey I’m just a normal guy, changing lives one ebike conversion at a time😀🤣
You remind me of a younger Harley kid so I'll follow...
Fantastic build, thank you! I’m taking it a step further with the Luna BSBF-1 Stabilizer Bar so the motor ain’t going nowhere!
I like my throttle on the right side LCD on the left what I did great video I purchased my kit from Johnny great guy!
