I am using BAT-SAFE box when charging my ebike battery (Li-ion Panasonic 36V/15.6 Ah) in garage. Problem is that in winter there are cold days when outside temperature is below 14 degrees and garage is not well insulated - How to warm up battery in BAT-SAFE box in order to get at least 50F ? We...
When I set invalid parameter in the bafang tool and I will save it - whole 'profile' is not saved into controller but original setting of controller is somehow lost (e.g. changing max amps from 20A to 19A is not possible, only 18A is possible to save). I had to start from beginning (to set again...
Thanks for info. I agree that for 10% grade hub motor is fine when pedaling, but in my case have 3 sections of 13%-17% grade each 0.2mi long (path through forest) where hub motor couldn't not work properly even with my assistance (too low rpms)... That's why I favor mid drive motor currently.
Hi, I programmed my BBS01B motor from 18Amp to 20Amp max (using 36v battery).
I use motor purely in PAS mode (full assistance mode most of the time) and I am alwyas trying to pedal hard between 40-70rpm, depends on terrain.
Do you think I could damage gears or something else in motor in the...
Regarding torque sensing - it's nice to have it but practically when pedalling uphill it feels very 'natural' even without it :D
What do you think about reliability of such setup - BBS01 250w rated motor on 36v/20amp ? What will break first - nylon gear ?
I run mid drive motor BBS01 250w on 36V / 20Amp max so peak power is ~720w. As I am living also in EU I am happy that there's 250w sticker = legal motor. I use max assistance mode (720w) in steep 15% hill + I am actively pedaling as hard I can to maintain 10-12km/h speed. Total weight of me+bike...
it's precisely machined and bottom bracket is fine. Main difference is that stabilizer bar does not 'bite' to the side of bottom bracket. I will try to put more torque on M33 nut.
Also I will have to mount motor somehow to downtube (e.g. steel hose clamps - large diameter) - currently there is...
Hi,
I noticed that my bbs01 motor is not fixed enough by stabilizer bar (https://california-ebike.com/shop/bsb-1-bafang-stabilizer-bar-bbs0102-bbshd). It's slightly moving (+-1mm ~ 0.04inch) inside of low bottom bracket (picture below). In my opinion that M33 axle nut is really tight ~ 50-60nm...
I as understood optimal cadence for BBS01 250w is around 70 RPM. Let's say I will maintain cadence around 70-90 RPM in long steep section (e.g. 15% on 0.2mile) - in that moment I need maximal power from my mid drive motor. I do not want to use throttle (illegal in my country) only PAS. My...
Hi,
I installed BBS01B 350w mid drive kit today, my 29" frame is a bit wide - it would be great to have chain ring with better offset (currently I have 'default' chain ring 46t installed - it has about 9mm (0.35 inch) offset. I am not able to use two largest wheels on 10sp cassette (11/36) in...
I would need chaing ring with improved off-set and I seems that this site no longer works ? (I cannot register there) :

any other ideas where to get 42t chain ring with better offset for BBS01B ?
Quick update :
I borrowed 250w bike yesterday (bafang BBS01 250w) and it really shaves off 50min of traveling time as I originally planned (with active pedaling). I had problems only in steeper sections >7% where my speed was sometimes under 7mph (10km/h) with active pedaling (~140 heart rate)...
