Best presentation of the critical fit issues I’ve ever seen.

This is the most detailed video I saw about fitment of these engine. GREAT GREAT work.

Very useful guide for me as I had a bit of trouble getting my head around what to consider in relation to fit. This made it a whole lot easier for me after watching so many other conversion videos. Much appreciated.

Very well put video. I knew these things but I will use your video to help others with problems on their mid drive builds.

This is by far, the BEST video I have seen explaining the considerations one must take if one is going for a Bafang motor. Thank you for posting!

An excellent video explaining the topic at hand. Thank you. You have become my "go to" channel for information on e-bike building info based on the fact that you explain things so well.

3D Models are so useful when explaining~! I've read a lot of this in guides before but Im a visual learner no doubt. Thanks again Capt as always!

Thanks for putting up this kind of data. It helps fill out some questions. Be Well.

The most perfect description of the issues, thanks for all the effort. You can see from the frame I used in my FS fatbike, I found one that would allow the motor to sit behind the BB..much better for dropping over rock edges. Though the frame has other issues :(

that helped me a lot and clering up some things thanks

Awsome explanation, I just received my BBSHD motor and installing it on a hardtail fat bike. I have been watching all of your videos, especially since you live only an hour away. You definitely have a big fan here, thanks for the help.

Excellent tutorial. Thank you!

This video is god tier, thanks

Thanks for your videos on bbshd, in my opinion best on youtube!

fantastic video, so many details you could only learn by trial and error given right here. Very useful information to keep in mind for my build, thanks!

Super helpful, thanks for putting it together!

Well explained and nicely done. Good job, mate!

Excellent tutorial bro. Thank you

It might be useful to 3D print a true to size shell of the BBHSD to mimic the unit with the various spacers so that people could trial fit it to their bike before making the big decision.

Oh the memories it brings back and me thinking I wanted a 13 sp rearend. At least i can climb every hill in town. I had to have a special wheel and a special order bolt through axle cause i wasn't about to try it with a drop out or any thing else that could fall apart.

Another great video. Thanks!

Thank you for this.Very informative 👌

Great info! I’ve been looking at full suspension frames for this motor.

This video is tremendous help! Thank-you.

This is highly informative.

Good info, well presented 👍👍

Excellent!!

Great content. Regarding chain line. I dont think you mentioned but a lot of people including my self also use a chainring that has an offset to allow a better alignment. But since this is new I dont think new chainrings with various offsets exist yet. It worked great on the older BBSHDs which I agree has been bullet proof so far with over a year and half of riding mostly on mountain bike trails.

great video... highly appreciate it. thanks

What an exelent informative video!

nice

I do not see a 120mm version of the Bafang M625 available as of yet. I would imagine the 100mm Bafang M625 would still have problems fitting to most modern Fat Bikes because of the chainstays. Also, the company (Eunorau) advertising the Bafang M625 motor states on Aliexpress that "Bafang M625 with CAN protocol, the motor is only compatible with BT F22.960. C battery". Seems like the new motor has very limited options.

I would like to have a bottom bracket drive utilizing a belt into a Rohloff drive on a disc brake wheel.

Very useful info, and mentions issues I've already thought of myself. I'm looking to build my first e-bike and need a bike to start. My main questions involve where the final chainring position will end up with the motor installed. I'm assuming the chainring should pretty much be where it was originally for a good chain-line. But the bikes I've looked at have chain stays that flare out really wide immediately from the crank area, making me wonder if a larger chainring will fit without hitting the chain stay. I know I could space the chainring out but then the chain line might be too far off. I wish there was a list of MTB bike brands that are the most suitable for these mid drive Befang installations. I wouldn't want to buy a bike to realize that I made the wrong choice for this.

Really useful information....I’m just about to purchase a kit for my surly pugsley fat bike and just assumed that as my bb she’ll measured 100mm I would need the 100mm kit..would you say the 120mm kit is required?...

love your models!!! did you make them on solidworks? did you share it somewhere?

Thank you Captain! But there were the same mounting problems with the old version of the BAFANG BBSHD. Does the new model cause more mounting problems?

Great video 👍 would you know if there’s clearance issues with a fixed ISCG mount?

I've been building, This will be my third e-bike and was going to be my final e-bike. I went and bought a carbon fiber Chinese knockoff gravel bike. It is fantastic! It looks awesome but it has that weird BB dip where it then meets at the rear fork parallel but I forgot what the dip is for or something for the chain so you can get to it easier or something. But like the bottom bracket has one side protrudes way lower than the other side. It's a weird looking angle. I didn't know that I got the upgrade kit. I got the high voltage upgrade kit bought a brand new bafang mid drive motor and it hits that little bump and it's carbon fiber so it's not like I can shave it down. Do you guys make some weird like it won't even align up straight with the bottom bracket hole at all. It's off by like a half inch and I'm debating about giving up and just going with a hub motor but then I can't use a hub motor because it's a thru axle and so I wouldn't even be able to get the hub motor on the frame if I wanted to without professional help. I guess I don't even know if you can take the axle off the motor and then put it back on and our own backyard anyway... Lol. On a side note, e-bike magazine or whatever the e-bike magazine had on the cover said it was the world's fastest aftermarket e-bike and it was on a heavy mountain bike frame and could go a top speed of 70 mph and like 0 to 60 in like 7 or 8seconds. Said it was the fastest street bike out there. The current bike I have now can go over 88 mph and 0 to 60 in like 4 seconds if I can control it without snapping the chain. With only 3000 watt mid drive motor .there was like 5,000 watt hub motor. They're hub motor weighed more than my whole bike put together . And it is completely carbon fiber except for the battery and motor. Everything else I mean everything else down to the carbon fiber. Spokes the rails that hold the seat are carbon fiber. Everything is carbon fiber. The whole bike weighs less than 35 lb and I mean it is futuristic to the max. It is a road bike. You never see people converting road bikes. I always thought that was weird because I want the fastest road bike. Haven't been like to drive a car since 2009 and when I keep up with cars and the bike lane next to them it is hilarious. Seen their expression because they can't seem to accelerate faster than me no matter how hard they try. Even the Ford mustang GTs are the only one that can almost accelerate faster than me. Am accelerating using pedal. Assist the whole time not the throttle. If I were to use the throttle it would be ridiculous. I would burn rubber on my 700c tires is kind of funny. I keep it in the lowest or the highest RPM gear and Mike acceleration is through the roof. But I want to make the fastest gravel bike in the world and I would feel much safer putting 38 mm to 45 millimeter mountain bike tires on Earth road. Bike frame would be epic and now I'm a little sad cuz a problem and I don't want to have to buy another carbon fiber gravel bike frame. I took it two months to get here from China

OMD !!! Your opening lines !!! HAhaahaha .... Doh!

Thanks for the video. You mentioned you had to use a120mm and spacers on your fat bike. I have a 2013 Salsa Mukluk bare frame with a 100mm bottom bracket. Do you think I should order the 120mm just to be safe? Thanks

Where did you find your CAD models of these bikes? Do you know of any for the Cannondale Prophet? Also, where did you get the model for the new BBHSD? I would like to model my bike (in SolidWorks 2018).

What are the weight differences between the hd & the m625? I heard it is made out of magnesium. Can you pull the same power out of a bbs02 w/ a asi800 compared to a hd? The reason being I've seen options for a belt drive on the o2 but not really for the hd...any thoughts? I'm really set in converting belt drive bike there is one person I've seen w/ a hd running a belt drive on the same bike...he had told me that his conversion was a custom machined front chainring adaptor...it seems a bit over done. I'm working w/ a 104bcd 42t front sprocket...i also got a gates 39t sprocket as well.

I am thinking about upgrading my controller to the Phase Runner. I was wondering what your experience doing this is like? Thank you.

Do you know of a supplier for an adapter when the bike has a larger diameter bottom bracket ie.41mm

Hello 👍 ,, you can change the pin (motor) that enters the frame of the bottom bracket,!? Let me explain,. I took the 100mm but, Pultroppo with the dissosamento chain crown house we are not there. He strains too much arrived at the 9 speed, from 10-11 goes hard and eats the iron. Since I have a 148×12 mtb wagon. No more margin even with picnic crown that I recovered 5mm .. Nothing! It doesn't work. So I would like to try on my old 26 rockrider 5.2 mtb.. Or at least frame that can mount this 100mm with normal mountain bike front wagon

do you know if a bbshd 100mm will fit ok on a 68mm bottom bracket with spacers?

Thanks for the helpful video. Can you confirm the dimension of British thread BB is 68 to 83mm not 68 to 73mm ? I have found the later dimension of 73mm max on a BBSHD supplier's website.

I don't understand. I just bought this blindly tonight and read some comment after the fact about having to buy their battery. I just bought a new 43ah 52v battery I don't want to go back to a 20ah battery. Can I use my own battery ?

This new generation of bafang motors are objectively fantastic but for the owners of the old models were left a bit in the lurch. I'm very confused as to what's going to be swappable between generations and exactly what the difference between the news models internally. Then also I saw a lack of 120mm models? And also programming these like the old ones seems harder. Confused.

What are the main differences in the old and new BBSHD?

You mention a link to downhill frames that work well with a BBSHD? I don't see it.

Would a bbhd fit a 2017 cannondale bad habit carbon 2?

I have regrettably come to the conclusion that my Giant Reign 27.5 2 might be a bad ebike conversion due to the sloped lower tube. I really love that bike, but think it would get a terrible ground clearance due to this.

My tsdz2 motor will not work without modification on 2 frames that have internal cable routing, at the bottom bracket the internal cables exit blocking the bottom bracket.

is there a reason I hardly ever see these motors attached to roadbike or gravel bike frames?

What do u use if u have a 86mm BB ??

LOL found out to my misfortune today it didn't fit my frame which was a 16"! Got a 19" Dawes bike Off gumtree on it's way tomorrow so should? Be ok

The M625 adds a huge (literally) additional issue of requiring the proprietary Bafang battery that comes in one, giant, ugly, form factor.

Hello! I have had issues with this motor coming loose after tightting it with the correct torque and additionally applying Loctite to the grey Locknut. Raised ridges are facing the bicycle and are bitting into the frame but after some time the motor comes loose. It's a very annoying problem I have that prevents me from enjoying an otherwise great kit! Any suggestions people?

I have the best DH frame for the motor is the mongoose boot’r
