Hi

Thanks for the reply ive attached this picture. Hopefully it will be ok to do the conversion too. Just ordered a 20 spine socket and tool for the bb. Hopefully it will come off ok. I've never done anything on a bike bar put air in tyres.

Kind regards

You won't be disappointed with either the BBS01 or BBS02. Just thought I'd point you to a thread which may be useful to you:

The Bafang installation tool is especially useful.

The bbs will fit ok, the bigger the battery ah the longer the range, make a cardboard template of the frame triangle check size for fitting against the battery case style you choose the higher watt bbs02 motors need higher ah [ i learnt the hard way purchased to bigger battery to fit in the frame]

Thanks to everyone for posting up. If i get bored of the 250w bbs01 is it easy to derestrict or upgrade? Thanks for tip on the battery!!!.

Yes limit is adjusted via the display or by the laptop cable as you are into cars think remap
A decent battery can be almost the same price as the kit or a cheap Chinese no name option choose 15 or17 ah now they have got cheaper if you want longer range or 12- 13 ah if you want to save weight
But most of all its cell quality or brand that affects cost but most of all enjoy your build

Thanks Peter for the information i understand ive seen the usb leads for the motor. What sort of speeds will a 250w obtain on a flat road? 36v battery? Will enjoy the build. Love a project.
