Does anybody else have this problem?
My maximum current on mode 1 is 17% (of 30 amps) which is roughly 5 amps.
This means I should be peaking at around 250 watts. However, my BMS app shows I’m drawing over 9 amps, and over 500 watts.
Why is this happening? Is this normal for mid drives?
Everything feels tight. That green “nut” (not sure what that’s called) is as tight as it gets
Can anyone recommend a chainring and cassette for flat ground commuting on a 29 in rim bike with the 750w midrive kit?
I'm trying to strike a balance between chain line and reasonable gearing.
I figure it's not best to have a tiny cog on the rear as your max speed as it would wear out very quickly
Hey everyone,
I recently picked up this pedal go-kart/project cart and I’m thinking about converting it to electric using 2x Bafang mid-drive motors, one driving each axle.
I’m mainly wondering:
Has anyone here mounted a Bafang mid-drive on something other than a bicycle, like a go-kart or cargo project?
Which motor worked best for torque and low-speed use?
Any issues with chain alignment, gearing, or overheating?
I’d love to hear from anyone who has tried something similar—or if you think this is a terrible idea.
Thanks!
Anybody know the total diameter of a 36t lekkie chainring the varstrom 42t that came with my bbso2 kit won’t clear the frame
Does anybody here use the Daniel Nilsson tuning software on their BBSHD?
Can you please share your tune (screenshot or file)? I'm really having a hard time getting it to ride the way I want.
Speed limits and power per assist level aren't being respected, not sure what I'm doing wrong.
It’s been a few years since I’ve built my bike, now my buddy wants one and Im double checking components before starting his. Is bafang still the go to for mid drive?
I am planning a custom build for a emtb and have some questions.
The frame is a Light Carbon LCE28 that fits the Bafang m620. I was quoted $1033 USD shipped for unpainted. Seemed a bit high? I was expecting 700$ or so.
Is the 620 the best, current and most powerful mid drive motor available? I haven’t seen the 630 for sale anywhere, and I hear that it isn’t reliable. Is that true ? Or should I be looking for that motor instead? Would it still fit that frame? Should I be looking for UART or Canbus for the 620/630 motor? I know UART can be programmed more easily, but canbus is newer? I don’t need to tinker too much with programming but I’d like to unlock the top speed and maybe adjust power assist levels. What are good prices for these motors and where can they be found? I would be shipping to California.
Thanks for any help.
Hello every one
I am thinking about going from TSDZ2 to BBSHD. The main reason being the reliability. The TSDZ2 being reliable enough, I did not get any of all the ones I've use to go further than 15 000km (9 200 miles). And the BBSHD look like something that last very long.
The question I am asking is : how is the BBSHD at "low speed". I will not use it over 25 kph so I need to now how it will behave at these speed. Is the motor smooth or does it stutter for being "not enough stressed". Is it comfortable to use at these speeds ?
If you have used torque based motor and cadence based motor, I would be glad to ear from you about the differences.
PS : I know the TSDZ and BBS are not alike in term of type of assistance, the TSDZ being a torque sensing base motor and the BBS a cadence based motor. But I am at a time where I just want a motor that will not break, and that I don't need to think about for years.
The spot where you can see a dark circle is where the other water bottle hole is. The position of the battery mount is perfect right now for the battery fit, but the holes don’t match. If I were to mount it like this only one frame hole would be able to mount. What should I do? I’ve tried making a hole in the battery mount, but stopped because I didn’t think it’s a good idea before asking people. Any suggestions?
The large markings on the bottom side of the case indicate it's a 250 watt, but the smaller markings at the top of the case indicate it's 750 watt?!
Does bafang just use the same outer shell which has already been factory stamped with the 250w model numbers and then just put in a 48 volt controller and the guys for the 750w??
Has anyone come across this before?
Hi guys, Looking for a little help, My bbs02 has started acting strange, when I'm riding the motor cuts out after a few turns of the pedals, the display stays on with no error codes, I need to turn the display off and on to get it running again and the same thing happens.
Hi all,
What model is this and how old is it?
Any maintenance needed?
Thanks
I've been using my BBSHD for 2 years now and recently read about the "karl's special sauce" tuning profile. I then downloaded the correct .el file and the bafang config tool. I have a UART programming cable from golden motors. Plugged everything in, connected to the right port, clicked READ in the config tool, imported the profile, clicked WRITE on all 3 tabs and then closed the software. Now I have read somewhere that I should have clicked WRITE FLASH instead.. Anyways I then powered on my bike and was faced with the 30H error code on the display. I had my original profiles backed up so I tried replugging the bbshd to my PC again so I could revert everything but it is now unable to connect properly using the config tool. The READ and WRITE options are grayed out and the software doesn't seem to recognize that my bbshd is plugged in. I've tried rebooting my computer, reinstalling the software, unplugging my battery for 30mins, checking every connection in case there was a bent pin and a couple more things but no results. What are my options here? Do I need a new controller? Would buying perhaps an Eggrider V2 fix this issue? I'm entirely clueless and AI is really not proving to be helpful for this..
