750W mid drive Bafang Install and test on 29er MTB

[@frederickwoof5785]

I used the same kit with my conversion. Only mod I did was to put another rivnut in frame, to hold heavy battery secure. Plus two velcro straps.

Awesome video steve! You are very knowledgeable on ebikes and I’m glad we got to ride together

[@MarioGoatse]

Man you make this look so easy. I’m pretty handy myself, but I think I’ll buy a Giant Talon E+ first, then if I fall in love with e-bikes I’ll build my own with a fat mid-mount on it. Something with a lot more power than the 250w 50nm that comes on the Giant SyncDrive Core. Definitely looks doable to me though. Really appreciate this video. Cheers

[@ferguson8143]

I would atleast go with the 1000 watt mid drive with a 52 volt battery so you can them get the peal watts out of the motor which be 1500 to 1700 watts

[@rannaa1990]

I think this is the other way around, you build your own ebike because its cheaper. If you buy that Giant Talon E+ there is no need to build another ebike :).

[@Random-ed2xf]

​​@@rannaa1990Pretty much I have a older Iron Horse Warrior with a steel frame. Bike is heavy but can take more punishment being steel along with being built for down hill mountain biking. So I was thinking mid drive or MXUS makes geared 1000 and 1500w rear wheels. Both I can build for around $700 give or take including large capacity battery.

[@mikethomas6051]

​@@ferguson8143you get 1500w peak power using a 52v battery like i get from mine, using em3ev

[@denseljosephs9500]

Nice build thanks for the upload.

[@HB-yq8gy]

Nice I just got done converting the same motor on a Trek 4500 my BB fit perfect no spacers needed. My battery is weak kit came with 48 v -10ah on pedal assist 3 fast on flat but, for climbing assist 5 max is much better but battery drains fast. Should have gotten 52v 25ah or 52v 14ah battery. Still fun as hell I get about 18 miles riding 3 -5 pedal assist mostly flat ground graval. I did install gear & brakes sensors..

[@tomasgulas]

R therr options for pedal assist and throttle on all the kits?

[@ferguson8143]

​@@tomasgulasyes go with the 1000 watt mid drive with a 52 volt battery and a 30 Amp controller and with that you can have up to 9 level of pedal assist and or just throttle If you like and if you have a program cable you can also customize the motor and each setting to your desire

[@simonjohnhinton1938]

The great thing about the mid drive is that you can climb some insane gradients that other drives won't. Downside obviously it puts alot of strain on chain and freewheel so good idea to buy new when buying the kit. I have a 2015 Kona fire mountain 27.5" Mtb which I bought for peanuts and is in great condition and wondered if the 250w would be enough (uk legal) or should I give two fingers to the law and get a 750/1kw instead?

[@mikethomas6051]

Go for the bbshd, the uk law is backwards and given they want to get away from eu law which forced the uk to adhere to before brexit, i use bbshd, i run both 48v and 52v with 21ah and 20ah capacity, done 70 miles with power left. Hills are fine on the drive chain if you don't abuse it with bad gear selections and low pas settings, i live in south west and hills are plenty here and steep. A few tips, buy a good chain, kmc is good, 9 speed gearing is all your need and best for chain alignment, get a good derailleur like microshift advent, don't buy cheap gear cassettes, if you use qr wheels in the rear the axle cones wear down fast, get a cheap thru axle frame, buy hydraulic brakes and use a cut off sensor you can mod onto it, i use 4pot brakes front and back now with 203mm and 180mm rotors.

[@92redferrari]

Need to warn potential DIY fitters that pedals, crank bolts and using the crank puller and bottom bracket can all be very difficult to remove. I went to the big bike retailer here in UK to help remove cross threaded crank and bottom bracket. It was worth it after many hours of massive force needed to remove bike parts. This seems to stem from the original bike builders not putting enough grease on these parts in initial assembly.

[@yousuf3115]

With the addition of this mid motor, does it mean that the front gears have to be removed

[@mikethomas6051]

Yes, you will not need them.

Great video on the install I have the same one. I was wondering how you did the motor spacing mine hits the frame too thanks.

[@stevemania1]

Thanks! And it's super tight lol

[@ferguson8143]

Thats ok if you don't have any wires or cables running through there other wise you need to make you a spacer

[@Eagle47782]

Hey! do you remember the diameter of your bike's bottom bracket shell?

[@localbroadcast]

Hard to tell in the video, but does the mid drive motor setup that you're using here let you accelerate without the pedals moving, or do the pedals rotate whenever you use the motor to accelerate???

[@18andlikeit]

Good video thanks.. just wondering if a 42 or 46t chain ring will fit most any 68-73mm BB bike frame without hitting the chain stay and still having a good chain line?

[@stevemania1]

definitely a challenge, ive got literally mms of clearence on both sides, def install the motor first when you get a bike in case it doesnt fit!

[@18andlikeit]

@@stevemania1 kind of hard to do before you buy the bicycle!

[@stevemania1]

@@18andlikeit Just return it lol! if the motor doesnt fit put the BB and crank back on and take the bike back and try another :D

[@18andlikeit]

@@stevemania1 actually the more videos I look at its not the chain ring as much as it is the gear reduction housing of the motor that hits the chain stay more often, so you have to shim the motor out which then makes the chain ring stick out to far for a good chain line. Returning online bikes is a pain in the .. maybe I'll get one at a bike shop but they're always more expensive.

[@mart43]

@@18andlikeit did you get a bike already I am in the same boat as you. I am thinking about buying one second-hand (in good condition)

[@gregorydobson4307]

Got the same kit on my 29 hardtail. BIG TIP. Try not to change gear as your pedalling as the force of motor slams chain into next gear really hard and you end up wearing sprockets/chain in no time. Think you can buy a gear change sensor that cuts motor as your changing.

[@stevemania1]

I use the brake lever as a clutch when shifting to avoid this😁

[@1viiyy]

I’m trying to understand how these work, does the motor only go when you use the thumb throttle or will it work as soon as you start pedaling? And as soon as you stop pedaling does the motor cut out or does it keep going?

[@stevemania1]

motor goes via thumb throttle or cadence sensor noticing the crank turning in PAS mode. Cheers!

[@triciamcintyre4947]

Nice bike,I have a 250watt bafang mid drive,I have one chainring at the front a 11 gears at the back 42-11,how can I get an extra few mph at the top end, would I be better putting a 500 or 750 watt motor in or changing cassette or chainring,I am getting lots of different feedback, cheers 👍🚴🏴󠁧󠁢󠁳󠁣󠁴󠁿

[@stevemania1]

Definitely go the bigger motors gearing I've noticed only helps so much, need the extra power to get higher speeds once you get more wind resistance

[@triciamcintyre4947]

Cheers👍

[@mikethomas6051]

I use bbshd, which is rated at 1000w but you can get it at peak power 1500w, if i change the chainring to 46t, which bafang has as a standard for those kits, i get good flat speed but lose rpm going up hills, if i use a 36t chainring i get less flat speed but better climbing speed, I'm using lekkie bling ring 42t for best of both, overall there isn't a huge difference, that will come from using more powerful motors.

[@taedollarsign]

What's that lock you put around the battery in the highlight frame before the video starts?

[@wahkitng4505]

you got model and website you buy from

[@southernebiking]

Great job on the build. Rather than moving the whole motor over the chain ring touches the frame, you can drop a spacer between the motor and the chain ring. This avoids the problem of the crank arm getting close on the other side. As I said great build, I will sub and follow To see anymore. Thanks

[@d1d1ka29]

Can you make a video about the xt90 connector and maybe explain how you soldered it and waterproofed it ? Thank you Great video btw

[@mikethomas6051]

Xt90 is a better connection for 12g wires and motors using high amps, all you need to do add spade or bullet connectors, crimp them, then its optional if you want to solder, for waterproof you just use heat shrink wraps, you can add a frame bag to hide them in also.

Do mid drives go through gears like a car? Like you wouldn’t set off in top gear etc?

That's how you ride a bike with a E motor or without. A normal pedal bike you need to start in first gear. It will pull away the fastest and less wear and tear. Anything with gears you start with first gear.

@@lassydogpie5390 im upgrading my bike to a 750w mid drive. Its a 1x11. Mostly for commuting to work. The mrs struggles with power up hills she is fine on flats but needs some assistance up hills. Im gonna get her a 500w hub drive, i think a hub drive is much more user friendly for casual riders who perhaps dont have the power and strength and fitness aswell as knowledge on bike gearing. Im hoping she can just point and shoot her way along bike routes with me. She doesnt do the one track down hill stuff. Basically like u said, hub is less hassle for her riding experience, hopefully gives her enough push n helping hand to pick the pace up, cause it sucks when she says she wanna come riding and i end up riding walking pace while she is peddling her ass off but struggling 🤣😂
