bbshd

Hello. I am finally putting the bike together. Some constaints of all kinds arose but glad to still be here and wrapping this up. The bike has large 29x3 hoops. It is a very heavy custom frame as wellm I am running a 3 speed IGH but it has a small 14 tooth freewheel. Will I screw up the gearing...

Hey guys I don't think I can find where anyone has talked about this up here. I'm AJ here in West Virginia mountains. I am looking to make my bbshd stronger. I was looking at the high voltage kit the will run it to 4000w and I have heard it's a good company. Now what I need to know is what...

My Bafang BBSHD motor cuts off every couple blocks. Sometime when accelerating, sometime when coasting. It can happen under any condition. I have to turn display off then on for it to come back on. I have tried unplugging brake and speed sensors. Please help figure out what the problem is. Thank you

I started my ebike adventure around 2019 and after my initial purchase of a BBS02 I was so stoked. I immediately purchased a BBSHD with a 100mm BB to put on a fat tire bike. Little did I know that good candidates for this are hard to find. My experience with FAT is limited to a short ownership...

NEW install, hot battery, display lights, no movement in chain. first attempt and manuel very sparce. ??turn on battery switch, pedal and increase throttle?? do you have to be goiing a certain speed for the engine to assist?? thks

I have my BBSHD installed and I like it. I have not adjusted the software due to me being busy. I ride on pavement and gentle single track. I run on about 5/9 and the power use is about 400 watts. I will twist the throttle at times because it is there. I have not connected the odometer as of...

I just finished a 77 km railtrail ride on my BBSHD equipped fatbike. At the very end of the ride probably about 500 yards from the end point the 17.5AH rack mount battery ran out out of juice. When I got back home and charged the battery the display shows a stop sign shape with the ! sign in...

Hi, A little bit my usage of the BBSHD. I've used the motor daily for the last 4 years. I only use throttle. PAS is not properly disabled, but It doesn't work. I had everything set up at a bike shop now closed. The assist level were from 1 to 9 and were working fine. Approximate output of all...

I come to find out after-the-fact this is a common issue on BBSHD motors, maybe also the 03 units - the crank arm bolts can loosen and if you don't catch it on time, like it happened to me, the crank can come off. About a month ago my cranks started squeaking a lot. The bolts were a bit loose...

I am relatively new to the e-bike scene. I am not looking for high speed as 12-30 mph is more than fine for my needs. I am looking to upgrade to a 60v 60ah battery for my BBSHD. My ideal setup would be a generic shell and buying the cells by a 100 pc. at a time. The questions that I am...

Dunno if overheating is a common issue with the bbshd. Was taking it up a steep hill to a frien'ds house i often visit, which i have done plenty of times before with this bike and this time it was feeling underpowered, and it used 20% of the battery, about twice as much as it has before to...

I'll absolutely be doing a full build thread with tons of pictures here soon. But I'm not 100% sure about some parts, and I was hoping some more experienced riders might steer me in the right direction. Thanks in advance! Kinda Light vs Kinda Heavy? I don't want to go 40mph, but do I want range...

How common is PAS level delay for BBSHD (level 9 still being active at level one for few seconds)? Throttle also sometimes gets activated at PAS 0.

Hello all i have a sondors XS with 750 watt bafang hub motor and want to convert it to a 1000 watt bafang mid-drive. my question is since sondors put these (XS) out with the bafang motor and matched the brake cut offs to the tektro Auriga E-sub, would i simply be able to plug and play on the...

How to make BBSHD more responsive to the start and stop of pedal assist? I pedal and it takes a bit of time to engage,and once going and I stop pedaling it feels like an eternity before PA disengages. Does anyone know how I can achieve a more responsive PA time? Thanks

The small bolts which fix the support bracket to the motor have stripped the thread of the housings on the motor of my BBSHD. What is the best recommendation to fix this issue??

So the real high-end fully-built cargo e-bikes, such as the urban arrow, the extracycle bikes, yuba... all come with either the shimano or the bosch mid-drives. I have been told by every salesperson that they are "the best". Of course i can't help but notice these mid-drives are HALF, (perhaps...

Will a battery with the following specs work with the 1000w 52v Bafang BBSHD- I am scared that 60A constant discharge current is too much? Nominal Volt: 52V Rated Capacity: 40AH Max Constant Discharge Current: 60A Peak current: 120A

What issues, if any, will I encounter if I connect a 48v battery to a 52v BBSHD motor? I did not know there where two versions of the BBSHD motor. Greenergy’s order process did not provide/offer a choice. When I open the box it had a 52v sticker. And a 48v battery is on the way from a...

I am going to use this thread to document the mid-drive eBike conversion to my custom-built pedal-pushing Nashbar mtn bike. Truth be told, ‘custom‘ is used loosely here - other than the frame, I only needed a top-pull front derailleur to complete the ‘customization’ from the donor bike, an Ibex...
