Hello, I’m looking for a bit of advice. I recently bought a B’TWIN OXYLANE 500E electric folding bike second hand. It’s in good condition and operates as it should but the controls are very limited, so I thought I’d try modify it and bought a new controller with display along with a couple of accessories/adaptors. To be honest I’m rather a novice at this sort of thing – I’ve converted a few bikes using kits but never had to cut wires and try to get everything to match up correctly. However, numerous YouTube videos and online resources have got me so far.
I quickly realised that Decathlon have (of course) decided to use a number of non-standard plugs and connectors that I’ve found nowhere else online, so I have had to do a bit of improvising. As it stands, the brake motor cut off sensors and the throttle are working, but the pedal assist is not. I think I have connected the latter correctly as the bike’s PAS sensor is receiving power (blinking red LED on turning pedals) and I’m working on the assumption that the one out of three wires which has a voltage change when the pedals are turned carries the signal. I have tried the other wire combinations in an attempt to rule them out.
However, the thing is the throttle only works when the phase wires ALONE are connected. When the hall sensors are connected, the motor does not move. I admit that, as the wire colours of the motor cable were the same as those on the controller, I took the chance that everything would match up but that clearly isn’t the case. I’m pretty confident the phase wires are correctly matched as the motor does move, plus they are considerably thicker than the hall wires.
My question is, should the PAS work regardless of whether the halls are connected? Or would it rely on them in some way? I thought the PAS sensor was more or less a simple switch. Obviously I plan to correct the hall wiring but I thought it would be useful to find out first if the two issues could be related. Any advice gratefully received! Many thanks
