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.

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 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!

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....

Just installed my BBS02 and it’s awesome; thank you for posting this and being a leader in the DIY community!

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!

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.

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 just finished installing a bbshd on my Trek 4 series. This video showed me everything I needed to know. Thanks Johnny!

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!

Thanks for this video. I successfully installed a Bafang mid drive on my mountain bike. Works great. Love it!

Finally, someone who at least mentions an all in one shifter/brake setup and sensor option!

Thanks for all the awesome and helpful videos! Your channel has been really educational for me and I just finished upgrading my old mountain bike to an ebike as a result! Having a blast with the bike now and if it wasn't for you it would still be sitting in my basement so thanks Johnny!

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.

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.

Nice going! I’ll be watching this one a few times.

i would say to you Johnny it was fantastic explained and you didn't go sort cut well done thank you very much.

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!

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.

My kit arrived today and I can’t wait to get it all installed

Ok, I’m going to get started by pricing out this Barfang kit for my trusty 35 year old Bridgestone mountain bike as soon as I determined the bottom bracket size. It’s a project that I’m confident of tackling and you’ve shown me that it’s doable. Thanks👍👌😊

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 🙏

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.

Just finished Bafang 750W install. Couldn’t be happier thanks for the great instructions.

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!

You saved my ass. Got myself a bafang... But messed up the setup. You got me back on the right track. Thanks dude!

Appreciate the video. It gives this old geezer knowledge of what to expect during a build and the tools needed.

You sir are the Bob Ross of e bikes, thank you for your guidance. 😊

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.

Dude! You just gave me the confidence to tackle this! Thanks

Thank you so much. Gonna do the mid conversion. Using this vid as instructions.

Just did a bbs02 on my hybrid bike, this was a most helpful tutorial! Because of you I had the necessary tools on hand and was able to enjoy my results quickly! My tip is that small diameter split-loom tubing is one's friend for cable management on these kits, makes it look a few percent less like a DIY project

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.

Much appreciated good sir. My life is changed forever.

Thank you so much for your invaluable information, highly appreciate it.

Great vid. Installed on a Roll Sport!

Excellent vid, you’ve inspired me to build a mid drive, cheers!

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.

Hey Johnny thanks for the help. My bike is now much more zoomy. Now I am doing finishing touches.

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 ;)

Its 3am, do you where the bike nerds are? Yep, you guessed it, watching your channel, lol. Johnny, great mid-drive install video. Thanx!

You are the only one spent time to explain the cable management

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.

dude! I bet this took so long to do! Thanks so much!

Great stuff!

My kit arrives on Monday!! can't wait. I have a wife and 3 kids but this will be lifes pinnacle !!!

Great guy,, down to earth, simple,, easy.. thanks

Thank you Johnny!

You're a legend and I owe you a beer. Thank you

Awesome and informative video, thanks!

Excellent guide. Had install done quicker than expected by referring to this video,

Ahhh!! No music - what joy!!! Thank you! My brain can focus 100% on demo. I really appreciate this tutorial and all the little details like brake lever positioning for ease of use, what can get jammed, etc. Saves a lot of bother for newbies like me. I want to convert a Trek Aluminum road bike (smaller for females) into an electric bike. It has nice gearing components I want to keep. The idea is to have full road bike functionality to get exercise but also to have the ability to commute fast to work on electric power when needed, and to do long bike rides with my small doggies in a trailer in back, run errands for shopping, etc. I have another road bike for hard core workouts but the electric one will be the workhorse. I will not do off roading, stick to paved roads, capable of climbing hilly roads in town, street bike wheels - no fat tires, no mountain bike. I need long range, light weight, fast speed to 25-30 mph, and reasonable cost. I want to DIY the install. I am very analytical and handy but not a bike expert and never done an electric install. If you can recommend something sleek with good engineering, I will buy it from you. I think from what I have read, Mid Drive beats the front hub or rear hub type of motors. Please do advise. I trust you. Complete newbie here.

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.

Just fitting a bafang mid drive, lots of advice on this video, thanks from n Wales UK

Great video, really well explained and thanks for sharing. Cheers 👍🏼

This was great, and you made it look completely doable. Bafang should pay you for this, nice work!

Never use torque wrench for undoing bolts! Other than that - great video. Expecting my motor/parts this week.

So many useful tips - this will be my go-to video when my motor kit arrives. Thanks!

I don't just watch this video. I study it. Nice work, John.

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!

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.

Great video thank you. I'm from UK and going to copy your step by steps on my Cube Aim pro hard tail.

Excellent video, thanks so much. I'm in the process of converting Schwinn Axum right now and it has been very helpful.

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.

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.

This video helped me prepare for neurosurgery because I have lots of zip ties and cable management is key. 👍

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’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!

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.

Great video, I'm buying a bafang very soon and this video helps a lot with installation.Thanks from the UK.

Great work! Thanks for sharing!

5:58 you should never use a torque wrench to break threads loose.

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?

Super inspiring video I'm gonna do it.thank you👍

JNO. Great information!

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.

I'm finding that , like origami, cable management is an art/science.

Excellent video Sir. Thank you.

Well done video! Excellent detail for a one man band!

Me speak good.. subbed 😎

I saw a tip from another video where they used a silver sharpie or paint pen to mark the brakes, shifters, and bar. Ensures they're reinstalled in the exact same location every time you maintenance the bike. I don't care enough to do that on mine but I thought it was a good idea.

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!

Very helpful video. Good work Johnny

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

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

Love it, the new chapter in your life xD Writing this, i have everything just fitting it now.

All the videos are great but this one is the best. Thanks!!

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.

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 ..

Thank you! I think I'm going to give it a try.

You're Awesome. Thank you for helping me to build my e-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.

Awesome video - got me through installing my e-bike kit on a Babboe City Cargo bike!😄

Thanks for the video.

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!

Great video. Helped with my install

Thank you, well done very helpful. Play through.

Get yourself some expandable sleeving black braided, the braided sleeving is great to run cables through, when you cut it melt the ends with a lighter to stop it fraying. Also I like to use a stainless steel jubilee on the top of the battery bracket, clamp the bracket to the bike. You need to pinch the jubilee and push it through the fastening slot, then slide a nail through and tighten it to the frame so you don't just have the bottom two screws holding it on. You can use black electrical tape to stop it scratching the bike frame. And lock tight on most important stuff as my big heavy feet tend to loosen the pedals, lol.

It's official. I'm going to be watching this video for the next week.
