Thanks for the offer Mike, but I think I'm OK now. I did some further testing but actually connected connector 2 to the bike motor (previously I just measured the voltage with a multimeter). In fact the motor speed WAS controllable by the throttle, not just all or nothing as I had thought. I...

Well, here is what I have found... Connecting the battery, shorting the two blue "lock" wires and connecting the throttle, I get an output on the yellow and blue motor wires when the throttle is twisted. However, it's all or nothing - 0V or full battery voltage 38V and nothing in between. I...

Hi d8veh - thanks for the quick reply and advice. I'll see how I get on... Cheers John

Hi All I have purchased a replacement controller for my wife's 36V brushed motor Powabyke. The photo in ebay showed a distinctive controller model number for which I easily found a manual online. Unfortunately the controller that arrived, while labelled as 36V 500W (what I want) is a rather...

Hi d8veh - thanks for the quick response. I didn't realize you can run a brushed motor from a brushless controller - but if I did that (with a new throttle) without a pedal crank sensor, would I be risking it becoming illegal as there is no speed sensor on the bike as far as I can see..? One...

Hi Spanos, thanks for your reply. I have just posted the problem in the Technical & FAQ forum. At least, this is the problem with her most recently purchased bike. I can't remember what is wrong with the older one - that will have to be a project for the future - or I might end up using one or...

Hi All My wife's fairly ancient Powabyke Shopper developed a fault whereby the motor came on full speed as soon as the ignition was switched on. I tracked this down to a blown MOSFET in the controller. The controller has 3 large transistors of which one has blown - it is type Y20100DN (marked...

Hi I am John from Brighton, UK. I have joined the forum to hopefully get some advice for a problem with my wife's Powabyke Shopper. In fact she has two of them, both bought cheap second hand and neither works properly. Actually I'm hoping she might bite the bullet and buy a decent electric...
