Thanks for covering off the larger cable guide issue under the bottom bracket. So many others just gloss over challenges like that, leaving you to wonder what to do. I actually purchased a shorter one rather than cutting the old one and flipping it but that was a good idea! I just wanted to keep my old one just in case (chances are, I will never revert back anyway, but hey, you never know). Thanks for a great video!
Have no intention of installing this, but enjoyed watching this due to the excellent presentation, no unnecessary waffle, just clear straight talk. Well done. Learnt something too. 👍
Rev-becca, great video on installing the Bafang. I have watched all your Bafang videos and it gave me (a lady biker) the encouragement to install the bafang by myself on my bike. Your video are excellent showing all the steps needed for installation. I also watched other install videos made by other bike shops and they are not as good as yours. They skip some steps which I assume they consider too basic, but for folks like me who are not bike mechanics, I need to see how to remove the existing parts and then how to put on the new parts. I put the Bafang on myself using my husband's tools. The Bafang has made riding up hills a breeze and my overall rides more enjoyable. Thank you!! P.S. I replaced the stock Bafang ring with a Bling ring, have not had any problems with chain slipping, glad you suggested the upgrade.
It's pretty straightforward and fun! I have two Luna Banana BBSHD bikes, and I'm gonna convert a Trek my dad left in my garage with a 68 or 73mm Bafang middrive motor.
Thank you for the excellent tutorial, Rev-becca! Nobody ever mentions about the cable guide underneath the bottom bracket. This will affect a ton of modern bikes, including a Trek that I put a BBS03 on this weekend. But thanks to this video, I knew what to expect, and I did this same fix and it worked. Except on mine, the screw still stuck out about 3 mm too much even after modifying the cable guide, but it got me close enough to use a different fastener with a flatter head, and it worked.
Rev-Becca I followed your video almost word by word for my installation and it was great for a while. The little joint that stops the motor swinging around is useless, I used a big ass hose clip/jubilee clip to secure the motor to the frame so it didn't smash against it when the little joint failed. The base plate for the battery is very slim too, if you go on bumpy or offroad areas, you'll end up getting the 70%-0% power very soon. The battery disconnects from the connector momentarily, it causes a short that fucks up the battery terminals. Looked at battery and receiver and black everywhere like a little fire happened! The solution I found? Q-Tips/cotton buds. Wipe the battery connectors as clean as you can, then...reconnect the battery, go for a little spin. If it's all good, then get on to amazon or whoever your nearest supplier is and get a hose clip/jubilee clip that holds your battery and connector tight together, and clip them good to your frame and you'll be cruuuuuuising.
Good job mate 👍🏽 My guess is you didn't tighten the motor enough, nor secure the cables well. These days we use a chisel to hammer in the notches on the fixing plate, so it bites into the frame better. Then use a torque wrench with a specially made socket, to torque the lock ring up to 80nm. It's very rare to have any movement after that! 😁
@@Revbikes Cables were fine, motor maybe less so. Did a retighten everything at my 1500km service when I had time off work. I'd be very wary about over-tightening anything on an aluminium frame without the exact torque wrench though, last thing you want is to be cruising into work at 40kph, hit a bump, then your frame buckles and you have your back wheel wrapped around your neck before you know it 🤯 Off work over Xmas so another clean up is due, there's a noise that may be a sticking clutch in the freezing weather😫 Plus maybe a paint job, Giant must have had blind people picking their colours in 2012 when my frame was made😑
@@dubcindub15 tightening the lock ring will only cause the fixing plate to indent the frame more, it will not be damaged.. I would put serious money on that!
Rev-Becca- thanks so much for making your truly excellent videos. I just built my first e-bike, a Bafang BBS02B 750W on an Early 90s Nishiki MTB. It will make you proud. Have been riding my whole life and still a dedicated Roadie + Gravel Biker. My new e-bike is amazing thanks to your videos. Much appreciated.
The Nishiki Alien?I started mtbs in the 90s and that bike was one of the ones that caught my eye! Eventually bought an Alpinestars Almega DX as I couldn't find the Nishiki sold in Asia/Spore... :-)
Definitely one of the most helpful vidoes on installing a mid-drive unit. A lot of others don't explain the bit about the cable channels and the rear derailleur. Thanks
Watched your video a few months ago to install my Bafang mid-mount and found it to be very helpful. Just wanted to say thanks. By the way, as soon as I rode it, I completely understood your comment about people saying they might take the motor off as soon as they got in shape. I only went about 10 meters before I thought "I am never going to take this motor off"
Great video ! The first one that actually explains mounting the correct angular position of the motor - and explaining that it is for torque reasons. I have seen videos by other "professionals" who mount the motor at the lowest point .
73x65mm EBB on my Jones LWB steel frame gave me a run for my money. Ended up having a machine shop shave off the bottom tabs, weld the BB at the bottom and installing a Bushnell EBB. I now have a monster of a 750w ebike with H-bars, front and rear racks capable of sporting any pannier I like, and fantastic 2.35" tire handling.
Great video very informative especially as I am looking to get a Bafang mid drive, and this video has given me the encouragement try and do it myself Thank You from the UK 🇬🇧
Thank you Rev-Becca ! This is without doubt the best video on how to install a midmotor Bafang. I esspecially appreciate you pointing out potential issues with the gear cable guide touching the motor and also in using a rubber shim to stop the motor touching the rear gear cable. Excellent stuff. Bafang 750W, 48v 12.AH battery on a specialized crosstrail. Loads of fun
Using a Specialized Sport 2008/9 going to purchase 750 kit soon, just trying to decide best battery. Any help appreciated? Live in West Virginia, USA and it can be pretty hilly. State Reg’s say I can ride a Class 2 in any park or trail/road with no license or insurance, etc.
A nice pleasant voice for a change with good instruction. And thankfully no cheesy music. I wanted to see what held the Bafang motor from rotating and you covered it beautifully, thank you.
I was ready to buy a bafang mid-drive motor but this video made me opt out of it. If my bike has to get any mofdifications to put the motor (for those gear wires) then I am not going to do it. I thought those motor companies figured out that every normal bike has those wires right below the cranker so they somehow should have made the motors fit there without the need to make such modifications. Thanks for the video. It saved me from a ton of hustle.
I had exactly the same gear cable guide at the bottom, and made exactly the same modification. Now that I know this is the way it's done (probably the only way), I feel a lot more confident. Now to cable it up.
I got a Bewo but going to get a Bafang. 250W is max legal power in UK which is fast enough on a bicycle for me...22mph flat out. Pictures say a thousand words. Informative video.
Thank you for the info. I've heard some of this before but really didn't understand some of it until now. Must be in the way you presented it Good Job.
Ladies and Gents, by far the most difficult bit is to get the right tool for your bottom bracket; this is becuase there are a zillion so-called "standards" out there. Be aware also that some cheapo Chinese bottom bracket tools are correct for the job, but are so badly made they still don't fit(!) The second most difficult bit of the job is to get your tool to actually work, this is because bottom brackets are very often in *super* tight even when the bike is brand new. You will probably need to find a way of clamping your bottom bracket tool in place because, when you put serious turning pressure on it, it will want to "wring" out. Remember, remember remember, what she said here about which way the bottom bracket turns each side of the bike. You seriously do NOT want to make it tighter while you are trying to get it loose. Once you suss these bits of the job, the rest is generally a cinch. Thanks to the maker for the video.
Great video. Clear, concise, no time wasted. Excellent explanations and improvisations. There was nothing wrong with the music...volume was fine and its intent during ffwd was obvious. People just like complaining when there is nothing to complain about. Your shop is literally 500m from my street!!!
Great video, very helpful, and I liked the improvisation with the derailleur cable. Incidentally, the reason I have a repair stand is to remove the need for me to grovel on the floor with a screwdriver! Keep your videos coming :)
Thanks for the compliment Robert. Glad you have a stand if that's what you like. We of course have several too, but it wasn't working with possibility available clear background area for the vid. Also, at times, more force is required than a stand might stand 😉
Very informative. I just got my Bafang 750 watt motor and will be putting it on shortly. Rev-becca says..."Some people tell us they think they're going to take the motor off once their fitness has improved. Ha Ha Never seen it happen yet." I have to agree. I am sure mine will stay on!
Thanks so much. I have a Giant and I would have been lost without your guidance regarding the cable guides under the motor. I ran into that problem and didn't find the answer anywhere else.
Would you mind remaking every bicycle upgrade or repair video on UA-cam? You are a natural and a great roll model for half the population. Look forward to repairing half bikes I do now. Home improvement shows should have a bike improvement segment with you in it every show. Well done!
I noticed that whenever you apply torque to your tools, you pull. That is indeed the power direction for an excavator, but most techs, given the option, would use their body weight and lean into it. Not a push, but a controlled lean, using body mass versus muscle to apply force. Trying to decide on a type of conversion kit. This mid-drive takes a lot of work and changes the drive train. Thanks for the demo.
I own a Specialized Levo. Thinking what is better, buying an E-bike or installing a motor on a regular bike, I think the second solution makes more sense. The manufacturers of E-bikes "improve" and change their products every season and if you buy such a bike you might get stuck without the most important parts if something goes wrong. With DIY E-bikes such a problem is unlikely to happen. Thanks for the video.
thank you so much! I was avoiding mid drive motors like plague because i was afraid i wouldn't be able to mount it but i think its quite easy now. We'l see ordering one now=)
I followed this procedure very carefully and it went together very well and looks great. One thing I did was to shorten the powercable and join it inside the battery holder using a terminal block. Very tidy. Is there a video on setting and/or tuning the unit?
Thanks, in the middle of my install I just waiting on the bottom bracket tool and a front fork that I broke previously w a hub motor. Can't wait to ride
Well done instructional video, thanks for leaving out or speeding up the tedious bits. One thing I would like to know, why doesn't the kit come with some optional bits, rubber shims, wedges, etc. for the critical area between the motor and downtube? With my limited knowledge of elementary physics/mechanics I feel that the the torque applied to the frame requires more than a piece of hard rubber which will over time compress and become dislodged. Also, it would be prudent to check and possibly re-torque the motor lock ring after a short break-in period.
Thank you so much for your tutorial, its empowered me to try this out on my own. Very clear and one of the best tutorials I've seen so far regarding Bafang installation.
A little bit Belt & braces putting Threadlock on with a locking ring! Good job you used the blue (semi permanent) type. Nice job with good explanations.
Just a handy tip from a retired Aircraft Mechanic who still has all of his digits. When turning a nut or bolt, try to pull the wrench toward you rather than pushing it away from you, whenever possible, especially while removing said nut or bolt. This will save your knuckles, big time. You always have more control pulling a wrench toward you rather than pushing away from you
Love this Video, I close my ears to the Music, this is the Best youtube film made on the Information to install the Wonderful Befang Cycle Electric Motors. At last, I now can convert my Scott 930 Mountain Bike into a Touring Cycle and recapture my Youth. Well Done the Lady from Down Under.
Rev-becca instead of using a piece of rubber or plastic to prevent the motor from blocking the cabled I used a piece of moldable epoxy steel (you know ; the clay like). I made little ball from it an pushed it in between the two cooling ribs that could touch the frame if there was no cable. After that I pushed the motor up till the clay touched the frame and secured the motor. Because of the cooling ribs and the round form of the frame tubing it can't go anywhere.
Very good video: Not too fast, not boring. Congratulations! One question: Is the chain not too stressed with the added power of the motor? Wouldn't a hub gearbox be better? They use wider and therefore stronger chains.
The one question I have about these BB motors is what happens to my converted bike now that I've moved from a 3 ring chainset at the front to a single one? Haven't I just lost two rings and the corresponding gears? Will the chain now be too long? What happens to my existing gearing system? Thanks.
You may have lost some gears, but normally it would be the lower gears, used for very slow hill climbing if you didn't have a motor. If you choose a chainring between the largest and middle, that will be best, no need to shorten the chain. You will GAIN five levels of assist to every gear also. You really won't need so many gears once you have the assist 😁
Sorry, did I miss the part about the battery and controller? Maybe another video covers that? NTL, a great tutorial on mounting the mid-motor. Thank you.
I'm only watching this to get my cranks off ...Ha I make me laugh .. did enjoy great info helped a lot going to buy the 48v 1000w wish me luck... happy trail's
thanks Rev, I happen to have a Giant bike w a hub motor I've been using for the last 6 years and am finally gonna transfer over to a mid drive from Luna, this really helped.
Rebecca, thank you for this is a very good and informative video. Are Shimano Steps cranks compatible with the Bafang BBS bottom brackets? Is it better to change the chain to a one that is especially for e-bikes, for example KMC e9? To going up steep hills, like 22 % grade, is it wise to take a cassette 11-50 and a chainring 28, 30 or 32 teeth? Thanks for replying.
Hello, thank you for your video. I am wondering about the adaptability of this engine with my bike. I have a distance of 78mm and not 73mm of length of tube in which to insert the bottom bracket mark. Can you tell me if I have to take a 90mm bafang motor or if the 73mm will be fine? Thanks in advance, Jean-Louis
Two years anf now three mid drive 1kw later i just bought a 750w mid dtive. Between two motors i have done over 20,000 kms. I just did a full tear down of the two older motors and all i replaced was one pas disc. The ring magnet had broken. The gears look almost new.
Great video! Feel more confident to take the task on fitting the bafang! One question what bike do you recommend so I don’t have to modify the cable bracket?
Question. I just got my bottom bracket out and going to put the motor in. Notice you're putting the chainring on before installing the motor on the bike. I'm probably going to replace the chainring at some point. I just want to see how the 44 tooth from the factory performs. Should I pass on loctiting the motor installation or can the chainring be swapped at a later date without repeating the motor install? Thanks for a great video.
About time a video tutorial for Bafang mid drives came out...Good vid as well.I recall there were some out before but it was in Chinese so unless you knew Mandarin it was mostly guessing what points were talked about in those vids... ;-)
hi thanks for video explaining! it better and safer to install the shift gear back or front? I meant to avoid malfunctions waters and others? it work better back or front?
I have 2500 miles on a BBSHD and have found that several times over the life of my ebike that the motor loosens and begins to droop. There are brackets that can be bought but the best solution I've found is a small sailboat turnbuckle. If you search the web for "Bafang Sailboat Turnbuckle" you'll find the fix. These can be sourced all over the web for cheap. Other than that my ebike has been alot of fun and very useful.
What is your opinion of retrofit mid motors that drive the rear wheel by friction? I hope you know what I mean. Seems to me like there would be extra wear and tear on the tire. But I would like to hear your opinion.
I now have a 27-speed hybrid bike. and I have 3 gears with my pedal cranks. now I wonder if those 3 sprockets are replaced by 1 sprocket and whether that is a disadvantage or not? So do you actualy get fewer gears then before the installation? Sorry for my poor englisch
Are the bottom bracket insert the same on all bikes? How do you know if the mid motor kit will fit on your bike? I never hear anyone bring this up when converting regular bikes to e- bikes.
Hi! Question please, if I follow the instructions but I don't put the chain as usual, does the motor work when someone pedal? I mean I only need the crank and pedals moving with the assistence of motor. Strange question but it has to do with a therapy for Parkinson disease. Thanks
Nice detailed look at motor mounting . I just had a look at your rev website , and got down to the bit regarding e bike laws and followed the link to gov e bike laws in our nanny state/country . A bit of a joke really the way laws in this state are doped down to the absolute lowest possible denominator , i had a ride on my brothers 250 watt e bike some years ago and , it was pretty useless for a fairly big dude such as myself .
You might find that the motors have improved in their torque since then. And running through the gears like these ones do gives you more torque lower down. But yes, higher power ROCKS! ;P
Should they not provide a small channel to accommodate any cabling? Rather than shimming it out a little behind the motor? I have a "ready made" e-roadbike, but would be quite keen to get one of these kits for my regular MTB.
My 2020 Talon 2 has Rockshox, Alivio, hydraulic disc brakes I got slightly used last spring for $600! I want to keep the 36t for maximum hill climbing. This is not intended to be a commuter. If top speed is 25-28 that's fine. Hopefully the 2x9 with 11x36 cassette 22/36 crank is a good donor bike. What do you think?
I'd like to do this mod to my ACME by SPOT, Gates Belt drive system with an 11spd Alfine rear hub system. Where would I get the appropriate front belt drive sprocket for this motor install/modification?
I haven't seen a Gates used with the BaFang BBSXX yet. I can't because I have a full suspension tour bike with a Rohloff Speed-hub. A mid-drive to a suspended Rohloff with a belt drive would be perfect, clean, quiet, low maintenance, durable and pretty. photos.google.com/photo/AF1QipMW6VP2OgxQVnUTqzm2yFEF-p9xXklItcc7CU7E
Thanks for the video, it demonstrated well including the pitfalls. And this is where I come in.... I have generally fitted hub motors and I am now looking at a mid drive but having watched this I am wondering whether all bikes can have one fitted. I have a Raleigh Royal which is a fairly old bike will it fit to the crank ok?
Richard, the Bafang should fit any bike with a 68mm Bottom Bracket. I installed it on my older bike with no problem of it fitting. If you do have the larger 73mm bracket there is a kit for the larger BB too. I used Becca's videos and my install went well because she gives you heads up on what issues could come up, especially regarding the cables running along the bottom bracket. I did have to make a small shim like she suggested to keep the motor from binding the rear brake and rear derailer cables. Good luck on your install!
Great, I couldn't hear it, but there is enough info to get me very interested. How much does a set cost in Australian dollars? Also I have the old style crank, is there a model that suits my trike.
Hi, if I have a Alfine 8 speed internal rear hub with a belt drive, can you get a front chainring for it, that will bolt onto your mid drive moto? If not, why not ? Cheers and good video.
I'm a bit surprised that up until now, there's no frame manufacturer that makes a bafang mid drive specific frame that you can buy and install the motor later on if you wish.
You can install it on almost any bike.. that's the point! Or, check out frames designed for the integrated bafang motors, an example is the Smart Motion HyperSonic
I have a question concerning the single sprocket. Why cannot there be two sprockets and reuse the derailleur? Could a slumpf drive (probably mispelled as I'm not taking time to look it up) be used? thank you for your patience. bf
@@Revbikes I want the extra gears because I don't always use electric assist. Do you know of any reason another sprocket could not be added to the front, or even a third sprocket like the trike came with before the assist was added? Thank you, bf
I was wondering how these bolt on motors were installed. Thx. Good information. I assume the bottom brackets on bicycles are a standard size? I have a terrific 1992 Miyata Triplecross that I'd like to convert. Can I expect any fundamental size/thread incompatibility issues or are the brackets all the same?

This is an easy video to watch, Rev-becca is a likeable person and I am on track to instal one of these mid drive motors.
Nice video. The motor bracket washer/spacers and the cable guide and the rubber spacer were particularly applicable to my Trek 300 Navigator.
Thanks so much. I have a Giant and I would have been lost without your guidance regarding the cable guides under the motor. I ran into that problem and didn't find the answer anywhere else.
Gracias , pronto estaré contactando a UD en rev-Bikes.
Extraordinaria explicación del montaje del motor Bafang.
Would you mind remaking every bicycle upgrade or repair video on UA-cam? You are a natural and a great roll model for half the population. Look forward to repairing half bikes I do now. Home improvement shows should have a bike improvement segment with you in it every show. Well done!
I get it. LOL "Roll model." Cause it's about bicycles & showing how to roll faster/better.
Why only a role model for HALF the population?? lol
This is the first time i saw someone smart enough to just open the derailer instead of breaking the chain.
Excellent video. Thanks for the very clear and focused camera shots
Awesome video, answered so many questions regarding cable routing etc. Thank you 👍
I noticed that whenever you apply torque to your tools, you pull. That is indeed the power direction for an excavator, but most techs, given the option, would use their body weight and lean into it. Not a push, but a controlled lean, using body mass versus muscle to apply force.
Trying to decide on a type of conversion kit. This mid-drive takes a lot of work and changes the drive train. Thanks for the demo.
I own a Specialized Levo. Thinking what is better, buying an E-bike or installing a motor on a regular bike, I think the second solution makes more sense.
The manufacturers of E-bikes "improve" and change their products every season and if you buy such a bike you might get stuck without the most important parts if something goes wrong.
With DIY E-bikes such a problem is unlikely to happen.
Thanks for the video.
thank you so much! I was avoiding mid drive motors like plague because i was afraid i wouldn't be able to mount it but i think its quite easy now. We'l see ordering one now=)
Mid drive is superior in every way, check comparison videos
Thanks for sharing this information. I have been thinking about building my own Bafang conversion, but you made it look simple.
I followed this procedure very carefully and it went together very well and looks great. One thing I did was to shorten the powercable and join it inside the battery holder using a terminal block. Very tidy. Is there a video on setting and/or tuning the unit?
Getting your cranks off sounds like a wild night.
Awesome tutorial!
The best instruction video for mid motors on UA-cam. Thank you
Thanks, in the middle of my install I just waiting on the bottom bracket tool and a front fork that I broke previously w a hub motor. Can't wait to ride
Must be a lightweight bike. Guess where it will break next.
Well done instructional video, thanks for leaving out or speeding up the tedious bits. One thing I would like to know, why doesn't the kit come with some optional bits, rubber shims, wedges, etc. for the critical area between the motor and downtube? With my limited knowledge of elementary physics/mechanics I feel that the the torque applied to the frame requires more than a piece of hard rubber which will over time compress and become dislodged. Also, it would be prudent to check and possibly re-torque the motor lock ring after a short break-in period.
thanks, good video, learned a lot. no junk, not stressful to watch, i liked the sweet voice and good looks of Revbecca!
Made this upgrade to m Fuji Absolute and now commute to work on my ebike instead of my former train/bike commute. Totally worth it.
Thank you great instruction especially the way the threads go on the bolts to take off and to put on the parts
Thank you so much for your tutorial, its empowered me to try this out on my own. Very clear and one of the best tutorials I've seen so far regarding Bafang installation.
A little bit Belt & braces putting Threadlock on with a locking ring!
Good job you used the blue (semi permanent) type.
Nice job with good explanations.
Just a handy tip from a retired Aircraft Mechanic who still has all of his digits. When turning a nut or bolt, try to pull the wrench toward you rather than pushing it away from you, whenever possible, especially while removing said nut or bolt. This will save your knuckles, big time. You always have more control pulling a wrench toward you rather than pushing away from you
Love this Video, I close my ears to the Music, this is the Best youtube film made on the Information to install the Wonderful Befang Cycle Electric Motors. At last, I now can convert my Scott 930 Mountain Bike into a Touring Cycle and recapture my Youth. Well Done the Lady from Down Under.
Rev-becca instead of using a piece of rubber or plastic to prevent the motor from blocking the cabled I used a piece of moldable epoxy steel (you know ; the clay like). I made little ball from it an pushed it in between the two cooling ribs that could touch the frame if there was no cable. After that I pushed the motor up till the clay touched the frame and secured the motor. Because of the cooling ribs and the round form of the frame tubing it can't go anywhere.
Great video. REV Ebikes are an awesome company. Would highly recommend them to all!
Very good video: Not too fast, not boring. Congratulations! One question: Is the chain not too stressed with the added power of the motor? Wouldn't a hub gearbox be better? They use wider and therefore stronger chains.
I'm about to build a mid-drive e-bike and this video appears on my watch list. Nice! And thank you!
Many thanks for this, Rev-becca. Excellent and much appreciated. Kaete
Well explained video, thank you.
Will this fit a BB92 press fit bottom bracket or would I need an adapter?
You'll need an adaptor
The one question I have about these BB motors is what happens to my converted bike now that I've moved from a 3 ring chainset at the front to a single one? Haven't I just lost two rings and the corresponding gears? Will the chain now be too long? What happens to my existing gearing system? Thanks.
You may have lost some gears, but normally it would be the lower gears, used for very slow hill climbing if you didn't have a motor. If you choose a chainring between the largest and middle, that will be best, no need to shorten the chain. You will GAIN five levels of assist to every gear also. You really won't need so many gears once you have the assist 😁
Great video, very informative but greatly reduce the music volume!
@CrazyFish Never thought a human being could possibly enjoy this horridly generic non-copyright music, yet here you are...
I just got my kit in the mail today. Looking forward to installing it. Thanks for the video. Looks simple. Hopefully it will be.
Took me all day because I'm an idiot!
Excellent video. Informative, professional and concise. Great work.
would this work on a chainless/driveshaft bicycle ? Sonoma 28" Women's 3-Speed D-Drive Bicycle, thank you.
Nope. I don't think so.
Sorry, did I miss the part about the battery and controller? Maybe another video covers that? NTL, a great tutorial on mounting the mid-motor. Thank you.
Yes, other videos cover that.
Thanks! My first install worked; credit to you.
I'm only watching this to get my cranks off ...Ha I make me laugh .. did enjoy great info helped a lot going to buy the 48v 1000w wish me luck... happy trail's
how much
@@edwlinbarragan1389 hi went for the 750w 48v about $850:00 very happy with it
Is nice includes battery an charger?
@@edwlinbarragan1389 no $1300:00 all up
1300 wow i think is good for 2 years
thanks Rev, I happen to have a Giant bike w a hub motor I've been using for the last 6 years and am finally gonna transfer over to a mid drive from Luna, this really helped.
Rebecca, thank you for this is a very good and informative video.
Are Shimano Steps cranks compatible with the Bafang BBS bottom brackets?
Is it better to change the chain to a one that is especially for e-bikes, for example KMC e9?
To going up steep hills, like 22 % grade, is it wise to take a cassette 11-50 and a chainring 28, 30 or 32 teeth?
Thanks for replying.
Hello, thank you for your video. I am wondering about the adaptability of this engine with my bike. I have a distance of 78mm and not 73mm of length of tube in which to insert the bottom bracket mark. Can you tell me if I have to take a 90mm bafang motor or if the 73mm will be fine? Thanks in advance, Jean-Louis
Two years anf now three mid drive 1kw later i just bought a 750w mid dtive. Between two motors i have done over 20,000 kms. I just did a full tear down of the two older motors and all i replaced was one pas disc. The ring magnet had broken. The gears look almost new.
Great video! Feel more confident to take the task on fitting the bafang! One question what bike do you recommend so I don’t have to modify the cable bracket?
Question. I just got my bottom bracket out and going to put the motor in. Notice you're putting the chainring on before installing the motor on the bike. I'm probably going to replace the chainring at some point. I just want to see how the 44 tooth from the factory performs. Should I pass on loctiting the motor installation or can the chainring be swapped at a later date without repeating the motor install? Thanks for a great video.
Just need to take the crank off to remove the chainring. Can be done with the motor in 👍🏼
I am thinking of getting one of these motors and your video is very helpful, thanks for sharing it.
About time a video tutorial for Bafang mid drives came out...Good vid as well.I recall there were some out before but it was in Chinese so unless you knew Mandarin it was mostly guessing what points were talked about in those vids... ;-)
hi thanks for video explaining! it better and safer to install the shift gear back or front? I meant to avoid malfunctions waters and others? it work better back or front?
Excellent thanks! If this young man can do it everyone can! He really made it look easy
Hi, Well explained! Can the original pedal cranks be used as usually smarter than the supplied version? thanks.
Only if they are made to suit a square tapered axle, and the right side crank doesn't have a chainring attached to it.
I have 2500 miles on a BBSHD and have found that several times over the life of my ebike that the motor loosens and begins to droop. There are brackets that can be bought but the best solution I've found is a small sailboat turnbuckle. If you search the web for "Bafang Sailboat Turnbuckle" you'll find the fix. These can be sourced all over the web for cheap. Other than that my ebike has been alot of fun and very useful.
You saved my life. I fell asleep in the bath listening to a lovely relaxing voice then omg what is that. Sincere thanks.
baahhaahhhahahaaa
Great and well produced video that will save me a ton of time, many thanks!
What is your opinion of retrofit mid motors that drive the rear wheel by friction? I hope you know what I mean. Seems to me like there would be extra wear and tear on the tire. But I would like to hear your opinion.
Wonder why everyone in the shop is working on their knees? The beauty of a stand is to STAND up... :-)
Great point. It's mainly because of the white background we were trying to use for the vid, and the framing of the camera.
I have that same bike stand, and I would guess that because it doesn't get quite as tight as a ParkTool stand is a contributing factor as well.
Great video! I feel much more confident that I can do an installation.
I now have a 27-speed hybrid bike. and I have 3 gears with my pedal cranks.
now I wonder if those 3 sprockets are replaced by 1 sprocket and whether that is a disadvantage or not?
So do you actualy get fewer gears then before the installation?
Sorry for my poor englisch
Are the bottom bracket insert the same on all bikes? How do you know if the mid motor kit will fit on your bike? I never hear anyone bring this up when converting regular bikes to e- bikes.
Hi! Question please, if I follow the instructions but I don't put the chain as usual, does the motor work when someone pedal? I mean I only need the crank and pedals moving with the assistence of motor. Strange question but it has to do with a therapy for Parkinson disease. Thanks
Nice detailed look at motor mounting .
I just had a look at your rev website , and got down to the bit regarding e bike laws and followed the link to gov e bike laws in our nanny state/country .
A bit of a joke really the way laws in this state are doped down to the absolute lowest possible denominator , i had a ride on my brothers 250 watt e bike some years ago and , it was pretty useless for a fairly big dude such as myself .
You might find that the motors have improved in their torque since then. And running through the gears like these ones do gives you more torque lower down. But yes, higher power ROCKS! ;P
Have you come across a bottom bracket the hole a bit larger diameter ( not length) than the Bafang motor shaft Thanks Ron
I have a pedal bike with an ALUMINUM frame. Is such a frame strong enough to carry a Bafang mid-mount motor ?
I was thinking of getting a stand so that I didn't have to kneel, is that one not adjustable?
It is adjustable, just was trying to frame the vid within the white background we had available :)
Hello, I have a 2004 GIANT TCR with Shimano Ultegra components. Which model Bafang mid-mount motor would work?
Should they not provide a small channel to accommodate any cabling? Rather than shimming it out a little behind the motor? I have a "ready made" e-roadbike, but would be quite keen to get one of these kits for my regular MTB.
My 2020 Talon 2 has Rockshox, Alivio, hydraulic disc brakes I got slightly used last spring for $600! I want to keep the 36t for maximum hill climbing. This is not intended to be a commuter. If top speed is 25-28 that's fine. Hopefully the 2x9 with 11x36 cassette 22/36 crank is a good donor bike. What do you think?
The music destroyed my ears thanks !
:D
I'd like to do this mod to my ACME by SPOT, Gates Belt drive system with an 11spd Alfine rear hub system. Where would I get the appropriate front belt drive sprocket for this motor install/modification?
I haven't seen a Gates used with the BaFang BBSXX yet. I can't because I have a full suspension tour bike with a Rohloff Speed-hub. A mid-drive to a suspended Rohloff with a belt drive would be perfect, clean, quiet, low maintenance, durable and pretty.

What does that tool look like used to take out the pedal axle from the chain side? That's a very specific use tool. Does it come with the motor???
Thanks for the video, it demonstrated well including the pitfalls. And this is where I come in.... I have generally fitted hub motors and I am now looking at a mid drive but having watched this I am wondering whether all bikes can have one fitted. I have a Raleigh Royal which is a fairly old bike will it fit to the crank ok?
Richard, the Bafang should fit any bike with a 68mm Bottom Bracket. I installed it on my older bike with no problem of it fitting. If you do have the larger 73mm bracket there is a kit for the larger BB too. I used Becca's videos and my install went well because she gives you heads up on what issues could come up, especially regarding the cables running along the bottom bracket. I did have to make a small shim like she suggested to keep the motor from binding the rear brake and rear derailer cables. Good luck on your install!
Great, I couldn't hear it, but there is enough info to get me very interested. How much does a set cost in Australian dollars? Also I have the old style crank, is there a model that suits my trike.
Hi, if I have a Alfine 8 speed internal rear hub with a belt drive, can you get a front chainring for it, that will bolt onto your mid drive moto? If not, why not ? Cheers and good video.
Rev Becca where do you get that flat tool for the lock rings? Thank you!
I got a complete tool kit with every tool you need to work on a bike for just under $30 (usd ) on ebay
It's made by Luna Cycles in the USA - lunacycle.com
I'm a bit surprised that up until now, there's no frame manufacturer that makes a bafang mid drive specific frame that you can buy and install the motor later on if you wish.
You can install it on almost any bike.. that's the point! Or, check out frames designed for the integrated bafang motors, an example is the Smart Motion HyperSonic
I have a question concerning the single sprocket. Why cannot there be two sprockets and reuse the derailleur?
Could a slumpf drive (probably mispelled as I'm not taking time to look it up) be used?
thank you for your patience.
bf
The front sprocket becomes the drive sprocket, so it's not practical to have 2. You won't need that many gears anyway with the motor.
@@Revbikes I want the extra gears because I don't always use electric assist. Do you know of any reason another sprocket could not be added to the front, or even a third sprocket like the trike came with before the assist was added?
Thank you,
bf
very good,ta much,im planing to do this on my scott,hope the bottom bracket is the right size.Thanks much.eoin
I was wondering how these bolt on motors were installed. Thx. Good information.
I assume the bottom brackets on bicycles are a standard size? I have a terrific 1992 Miyata Triplecross that I'd like to convert. Can I expect any fundamental size/thread incompatibility issues or are the brackets all the same?
She mentions about 90% are the Same. 68mm measured across width. But not all. Consult your supplier. Measure your BB.
