I love that you included all the hiccups in the process, this aligns with all my bike and auto projects. These kits are not guaranteed to fit every bike right out of the box and some left brained thinking is required. Thank you for this!

[@92redferrari]

Totally agree. 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.

[@ShareHobby]

Good Job!!👍 Im glad I bought someone else’s hard labor, trial and error DIY Bafang 500watt Mid-drive 29” Hyper Walmart conversion for $400. Seller did a good build and cable management. I simply don’t have your patience and skill to do a DIY mid-drive right.😅

[@Alex-nk6nf]

This really give me a very clear guidelines for turn a bike to good E-bike

[@mikethomas6051]

Few tips, don't stress yourself when building, do research on frame against what battery you want to use, check what sort of motor power you want, bafang do mid drives from 240watts to 1000watts at 48v, if you go for a power build bbshd use a strong frame and good enduro type wheels and strong brakes, once you remove any existing bottom bracket it's fairly straightforward, the connection of wires are very simple.

[@Ponyo3816]

[@bobsoft]

Awesome. Those Bafang motors are great. That tool in the kit is for removing the tapered crank arms. That was a lot of customizing!

[@RustBeltAuto]

Ooh. I thought they put that tool, and a light in the kit, to make you believe that everything is in that kit you would ever need, and want, for the job, in order to make a sale, while the instructions in the kit requires an imagination.

You had nothing but trouble with this install, fortunatley for you, you were knowledgeable enough to get through the hurdles… one question my brake cable is between the frame & the motor & it’s stopping my rear brake from working any suggestions?

[@RustBeltAuto]

Either it is pinched, or the bend is too sharp.

[@RitchieCaron]

I looooove my Bafang Rockhopper. You might prefer the 7 speed cassette with thicker chain when that one wears out at about 1500 km.

[@RustBeltAuto]

Sounds like a good idea, thanks!

[@magzire]

Great tips in this, I don't bother with the shifter or brake sensor. Just do a gentle half cycle on flat or down, or cycle a bit faster when shifting, so the motor isn't under load. When shifting uphill you need to click to zero, not a big deal.

[@mikethomas6051]

Thing about bafang, they are direct drive motors and only one model has torque sensor so you are not going to pedal enough to not put load on it, the torque alone is enough to cause damage on chain and cassette, the only way to do a shift effectively is to stop peddling with the cut off and let the motor travel through because the motor doesn't stop right away after you stop peddling for a few seconds, only in the programming can you stop this. I have three bbshd ebike builds, i was destroying my cassette and chains if i didn't use a cut off and pause peddling between shifts.

[@mikethomas6051]

Btw peddling harder doesn't stop load, it only adds to it surely.

I have my throttle on the left side. It's not bad at all.. theres just more room it makes sense. Also, the shift sensor isn't needed. I shift with the throttle applied but very little. There's no issue. I climb hills , so cutting the motor while climbing doesn't work for me.

[@JILISI_EBIKE]

[@RustBeltAuto]

now this, this is epic

[@MumfordJim]

Display is generally on the left side. Throttle can go on either side.

[@RustBeltAuto]

Ya. It's all a matter of opinion.

[@MumfordJim]

@@RustBeltAuto. Quick response. Usually it is put on the left because you have gotten rid of your front derailleur freeing up your left hand for changing power levels. Also if you want a better chain line you should get a Lekkie chainring to improve your chain line. Lekkie Onenut is nice to secure the motor.

[@RustBeltAuto]

@@MumfordJim the chain line will remain the same. It is as close to the chainstay as I can get it, and 2 less teeth will not be substantial enough to make a difference. Also, if you have been riding motorcycles, and wheelers as long as I have, putting a throttle on the left would just feel as wrong as driving on the left side of the road.

[@davelier9572]

Good video. I believe they sell a 73mm version of the Bafang, that is what you needed instead of the 68mm version. Also, you could have flipped the speed sensor the other direction so that the wire flows a little better.

[@RustBeltAuto]

The same motors are listed as 68-73mm. They are "universal". Unfortunately, I could not find a press in shell in 68mm, so I made up the 5mm difference with aluminum tape.

[@mikethomas6051]

No, there is no 73mm motor, i own 3 bbshd models, its 68mm but they will fit 73mm bb

[@roncooke2188]

Maybe because i am left handed it seems fine to me, although on my own ebikes i have throttle on the right also

[@AndreVr_r]

[@RustBeltAuto]

The display, and battery ya. I got the cheapest display, and take the battery with me.

[@markkus1134]

Nice I built a 29”r with a BBSHD you need a Lekkie 42 tooth with the offset works great it will correct your chain offset with the rear cassette with 160 NM of torque my bike rips

[@RustBeltAuto]

I looked into that, and figured especially for the price, it will not make much of a difference, and would rather just loose a gear. That sprocket will probably still hit my chainstay if I do not shim it out as well.

[@rawfromnowhere]

Fill the gearhousing with grease, and you'll get a much quieter experience. They put grease there from the factory, but it's not enough.

[@RustBeltAuto]

Grease? There is a lot of plastic in there. Can you be more specific as to what type of grease you intend to use? Furthermore, I don't think it will get quieter over the humming of those studded tires.

[@heraldreichel1971]

@@RustBeltAuto Most people recommend Mobilgrease 28 for the secondary (drive side) gearing in the BBSHD and BBS02 motors. I don't think it makes a lot of difference for the noise, but it's supposed to prevent damage in the case of water ingress. I also run studded tires in winter, they are extremely loud and I certainly can't hear the motor over that noise, with grease or without. ;-)

[@RustBeltAuto]

@@heraldreichel1971 thanks!

[@yurakryvets]

I also installed this engine for myself, but after using it for a year, I can say for sure that there will be problems with the chain and cassette, so I recommend installing Alfine 8 with a reinforced chain, I also recommend ordering a 500c display. 4000km +, ok

[@RustBeltAuto]

Sounds expensive. What happened to the cassette? I can imagine the chain being a problem. It's really thin.

[@yurakryvets]

@@RustBeltAuto I have an aggressive driving style. I like to ride hills or go fast, the main problem was always that the chain broke And of course the cassette wore out (or the Diore XT gear shifter bent) when I installed a planetary gear shifter (Alfine 8) everything became normal But the problems with the chain appeared again now I put one SRAM speed chain and it holds up quite well, also the chain tensioner must be taken into account, all this combined now withstands extreme loads. I am happy with my bike, I have accelerated my bike to 80 km/h and climbed big mountains and nothing has broken, I think such things should have a lot of strength reserve. My English is not native, sorry for mistakes) I will also add that it is not so expensive, but the Alpine 8 costs about $250-300 and the chain is $30, but this modification will withstand this engine

[@RustBeltAuto]

@@yurakryvets thank you!

[@heraldreichel1971]

If you want to use the largest cog in the rear, you might want to think about a chain guide. The are low cost (~20 $) and should prevent the chain from coming off the (front) chain ring. They were originally designed to prevent chain slap on single chain ring acoustic bikes, but work ok on ebikes when the chainline is off.

[@RustBeltAuto]

I think my chain will last longer if I don't use it.

[@heraldreichel1971]

​@@RustBeltAuto That's very likely. A chain guide will force a sideways bend on your chain, but it's very little. I've never even had a master link pop off, and they would be the first to go. However, your chain angle might be more steep. If you ever wished you had that highest tooth count gear, it could be useful, otherwise forget I mentioned it.

[@ibewillow]

Good video for someone wanting to fit these. They arent compatible with 12 speed cassettes because the chain is too narrow for the front sprocket, i think thats your jumping issue and why you cant use the lowest gear.

[@RustBeltAuto]

I did notice that some of the aftermarket sprockets look to have deeper teeth. Someday I may space out the cassette, and use less sprockets for a wider chain. Someone said I should do that.

[@Tomas-ml9nv]

How many speed cassette should I look for if I'm buying a buy to put on a bbshd?

[@ibewillow]

@@Tomas-ml9nv 11 or less.

[@RustBeltAuto]

@@Tomas-ml9nv don't much matter really. I only use like 7 of them mostly. The three smallest ones just burn up my battery, and goes the same speed, unless I pedal. Maybe because it's only 36v. The biggest gear on this can really crawl up steep hills. So I suppose it depends on the size of the sprockets more than anything. Less sprockets on your cassette will let you use a beefier chain too.

this is almost great but 25:27 why you don’t find some adaptor that includes it this kit at 2:40 and 0:39

[@RustBeltAuto]

There is nothing more to adapt. I could remove a gear, and use a spacer, but the result would be the same. The front sprocket is the smallest one with an offset that comes with the kit. I could spend money on one that is 2 teeth smaller, but it would be offset in the same location. It is as close to the chainstay as i can get it. The chain will also last longer if the chainline is straight.
