I'm shocked that video has only been viewed 1,300 times over 4 months. One of my mind numbingly boring videos about nothing whatsoever has quite irrationally, been viewed 18,129 times during the same time period. Weird.
Yes, we've chatted about that before. I uploaded destructions.
"250W" is stamped clearly under Bafang BBS01B motors.
You really should do it - it does seem folks who find hill ascension difficult, have bought the wrong conversion kit combination or motor type, or haven't configured firmware properly. I was quite content with my legal 250W manufacturer rated 36V BBS01B 20" wheeled Dahon conversion's hill climbing and bicycle trailer hauling capabiliy with the controller limit at 15A, but it's even better at 18A. Faster uphill at 18A, but it conquered any hill with only 15A anyway. Even with your heavier bodyweight and larger wheels, I'm sure you'd find 36V X 20A = legal 720W pedal assist with "Keep current" in firmware at 100% satisfactory. Most batteries seem ok discharging 15A continously, but it might first be a good idea to post details about your battery and BMS before increasing the amperage limit of your controller to 20A, for the battery experts to peruse.
If the DaFT make "500W" legal, I'd need to abandon folding bikes for the 500W BBS02B and a legal 1200W, to prevent my bike suddenly featuring a permanent fold, but quite honestly for me and my motor, manufacturer rated and stamped "250W" is more than enough.
