3d printed it, didn't want a rear hub motor as I wouldn't have anywhere to put the speed controller etc.

The crank on the orange one is a shimano that I stripped and polished myself, the powdercoating on the black one cost £40, and I got it done at Spraytech in Bishops Stortford. The £40 is just for the powdercoating, so I had to give them a ready to go frame that was totally stripped of paint in every crevice. Yes the tyres are bigger on the orange one but may switch those round at some point with the electric one.

Finally made the bike rideable, the only thing that isn't brand new is the frame which I stripped bare and had powdercoated. It rides really nice, but have ordered a different chainwheel as I can't get into the biggest gears on the cassette the way it is at the moment. I actually have two of these bikes now, one electric and one normal, I've tried to set them up so they are the same except for the motor, which included lots of measuring to the floor and the handlebars etc.

Yeah I don't intend on doing anything to it, I just thought the light came on with the bike, but I must be mistaken.

Well mine is off until the magnet passes once, then its constantly lit until the motor is powered off. It all works fine though.

The red led on the speed sensor doesn't come on when I turn the display on, it only comes on when you pedal and then it stays on, it is displaying my speed correctly without any glitching etc. Is it supposed to come on as soon as you turn the bike on? BBS02B Bafang motor. thanks

3d print worked out well but need to shave a bit off to fit my frame, will update with pics soon, worked out how it fits aswell, clever design

A friend is going to print this for me

Re attached it but feel like a knob for cutting it in the first place, this hasn't helped y OCD, also lost more length on the cable doing this as the heat shrink was shrinking as I was soldering so had to start again.

I was thinking of just wiring the controller straight into the battery with no connector involved at all, wish i had thought of that before cutting it but there ya go, I can't uncut it now. I was just trying to make it neat, but theres a load of other long wires that I can't cut anyway so don't really know why I did it. I have the capacity to make the cable coming from the battery as long as i want it to. Its a shame that the power cable is potted in the controller, otherwise I'd just resolder it there. Also i doubt this bike will see any water unless it starts raining whilst I'm out and I plan for that not to happen.

Hi, Stupidly I cut the power cable coming off the BBS02B, its 6 inches long now, I know I shouldn't of cut it but its done now, so all I can do is try my best to fix it, can I simply re solder it back together and use heat shrink with adhesive lining to make it longer again? I'm good with a soldering iron, i've spent the last 20 years tinkering with old R/C cars. thanks

Took some pics last night

P.S, the bike isn't finished yet, I still need to base coat and lacquer the frame, its an old GT Aggressor 2, 26" wheels. I had a 250w bafang on it in 2019, took it off, sold it and I'm now doing it again. Totally don't remember anything about what values to use on the penoff program though.
