Hello everyone,

Recently I decided to go electric and convert my 125cc motorcycle into EAPC E-Bike, but after doing some research there are still questions I can’t find an answer to :cry:
I would really appreciate your help!

My biggest concern is if it will be possible to create “gears” in my e-bike that will restrict the output of the engine to 250W temporarily to obey the law on public roads and then switch it back to 3000W on private land?
If yes, which controller will allow that (QS Motor 3.5T 3000W 205)?
I’m talking about just switching it on the display, simply clicking for example gear 1 to have power limited to 250W and then go for gear 2 for unlimited power
Would 3000W motor struggle with such 250W restriction?
Is 2000W motor a better idea in such case?

Thank you all so much in advance
 
It doesn't seem very practical to convert a motorcycle to a bicycle. How would you attached the required pedals that have to be able to propel it? It would be a lot easier and cheaper to start with a used donor bicycle.

Hello everyone,

I’m about to order motor for my next project and I found a perfect one on http://www.qs-motor.com/ but as it is not an AliExpress or eBay I’m just a little bit more cautious with sending my money via PayPal.
Anyone here ever used that website? Is it legit?

I have for the last years ordered all my motors and controllers direct from QS Motor Ltd and never had any problems and always had answers fairly quickly.
However, I am not sure on the site you have found, it is slightly different to the actual site I use. This is qsmotor.com. Below is the contact I have always used:-

If you look at their "Contact Us" page, it shows their AliExpress page: https://qsmotor.aliexpress.com/store/109978
