It is difficult to offer help here, unless someone has the same controller. Perhaps it would help if you posted some photographs.

Is that company still trading? Maybe they could help you out for a circuit diagram or even offer a cheap replacement board? Controllers are fairly cheap to replace so it might not be worth repairing it unless you can't get a replacement of course..

Another possibility is to buy a cheap controller from ebay . I believe your bike has a brushed motor, as opposed to brushless. you can confirm this , as if it it is a brushed motor it will have only 2 wires entering the hub.

Mark, if you ring Frank Curran of Powabyke directly as suggested above, instead of just "the company", you may well find him more helpful.

Brown, Black, Black, Gold, Brown which is 10ohms 1%, it also measures 10ohms in-circuit and feeds the input to the 7812 voltage regulator.

You'll have to use a fairly powerful soldering iron as the board is double sided and there's a lot of copper which will suck the heat right out of the tip, a 15watt hobby iron isn't going to do the job.

If the bike doesn't go after you replace it, the first thing to check is that the voltage regulator is outputting 12volts (from left to right in my picture pin 1 is the input, pin 2 is ground, pin 3 is 12volts out).
