Brought home a non working ebike today, got a sweet heart deal. first thing hot wired the hub motor (2 wire) and it ran fine.
Then started chasing problems and found the key on/off switch was faulty, Has two large red wires, so jumped them & rode the bike around the block.
Also has two smaller wires, any clues as to their purpose? When I replace the key switch, what should I do with them, cannot see where they are connected in the switch.
Plan on using the bike as a passenger (grand kids) & freighter would like to get more power. Do not want more speed, there is lots, so am thinking that raising the voltage would not give me much more power & would scare the pants off me for speed, but I can build any size pack using leaf modules, could install an overide circuit to bypass the controller to deliver max current.
Am becoming addicted to this site, constantly learning here, thanks in advance,
Tony.

So, with a bit of mucking around have got the bike working the way it was intended (I think).
The throttle only works if you are not pedaling. If you pedal, you have to release the throttle then the bike automatically tries to help you, so once on level ground you can quit pedalling and ride free.
Found out that it is a brushed motor (old school) and the controller is a 250 watt 8 amp device, if I buy a new 500 watt controller that will help a lot I think. My fear is not knowing how to tell which wires to connect where. Any suggestions would be welcome.

I know this is for a brushless motor but pedal assist should be close to the same. The two thin wires are for the brakes they cut power to the motor when you brake.

Thanks Floyd, the small red wire was connected to the orange wire and the blue wire went into the key lock, left the blue wire hanging in air bike worked fine, so took a chance and connected the blue wire to the other larger red wire, now the headlight is on if the battery is in its cradle. <laughs>.
Would like more power, and would like the transition into and out of PAS to be quicker and smoother. Paid $150 cad for the bike (owner wanted to get the money out of the new sealed LA batteries, and already have had my moneys worth. Old bike in very good condition.

From my 'little bit' of fooling with controllers / motors - it could also be a 'horn'?
Good call, but think the small red wire is the horn, will swap the 'blue light special' wire to the cold side of the start connection and put a switch on it.
