Hi
For my sins I have bought a Dawes Swift mid motor e-bike. It is in some disrepair missing the battery, and the controller was hanging loosely out of its box at the end of the battery jack-in assembly. It did come with some spare parts, a controller, a motor and an LCD unit all of unknown condition.
Before I dive in and invest in a battery, I want to try and check out some of the fitted/spare parts. Unfortunately Dawes ceased to produce this bike early this year, and despite polite responses to emails, it is obvious they have little or no information on the electrics on the bike (I think they have gone back to selling just ordinary bikes). I have emailed DAPU but they do not respond to emails - I even tried translating one into their language using an internet translator, but still no response. It would appear from their website that they are now producing a newer version of this motor and the controller (perhaps they threw out all the old information!!).
Anyway I am trying to identify the wiring out of the controller and the wiring going into the motor.
There are two black covered cables going into the motor, one contains the three phase wires and Hall sensing wires which is fine, but I would like to know what the other one has in it (eight wires inside).
The wiring on the controller I can identify is as follows:
Red and Black power in
Black cable from Motor containing phase and hall wiring.
Red, white and Black cable from the gear sensor
Black and red cable from pickup on rear wheel (speed?)
Red, Black, Green Blue and yellow - LCD and switch on handlebars
Two Blue and red connectors - lights?
Unknown
Black cable from motor containing 8 wires
Two connectors which were not wired out - one with Black, brown, grey, black and red - one with red, black and blue.
It would be great to have a schematic diagram but conversations with a few bike shops would seem to indicate they don't get any!!
Photos attached. Any assistance would be appreciated
thanks
