Re: QSMotor 4000W V3 17” Hub Motor Aprilia RS50 Conversion

I’ve asked them to come back to me on the higher A/phase rated version - It’s probably overkill for what I need right now but no harm future proofing the build if I can Thanks for the quick response and your other comments so far Can you do me a favour when you have time - could you post up a couple...

Re: QSMotor 4000W V3 17” Hub Motor Aprilia RS50 Conversion

I’ve looked again at the controller and made a change to my order - I’ve gone for Kelly KLS7245H which includes Bluetooth support and is also sinusoidal so should be a bit smoother on take off. I understand it’s been used with the 17” QSMotor 4kw hub motor before and should wire up easily enough.

Re: QSMotor 4000W V3 17” Hub Motor Aprilia RS50 Conversion

Thanks for the link to the battery - looks like a nice pack and it seems to be holding up well for you. I’ve looked again at the other Forum member who fitted the QS Motor 4kw hub into the same Aprilia RS50 frame and swingarm - they cut a slot in the rear of the swingarm that widened it enough to ta...

Valence Power u-Charge P30-36C

Hi I’m planning the build of an electric conversion of an Aprilia RS50 moped using a QS Motor 17” hub motor. I’ve been offered a couple of these 36v 30AH Lifepo4 packs, which I would be running in series to give me 72v 30AH. I need to be able to run at 60A continuous for periods of acceleration, and...

Re: QSMotor 4000W V3 17” Hub Motor Aprilia RS50 Conversion

Although the motor is rated at 4KW it peaks at just under 8KW and others who’ve used this even in 16 and 17” motorcycle rims are claiming decent acceleration if the battery pack can output enough As for take off, and top speed in excess of 80 kmh. I’ve managed to find a battery pack that would consi...

Re: QSMotor 4000W V3 17” Hub Motor Aprilia RS50 Conversion

Many thanks for the responses and apologies for over posting the same post! I don’t know how I managed to get the diameter for the hub/tyre combo wrong - basic error there, particularly as I’ve got the donor bike in front of me and can clearly see it’s 23inches+! I’d missed the other post using the ...

QS Motor 17” 4Kw Hub Motor

Hi I’ve been toying with the idea of converting an Aprilia RS50 for years and have finally sourced the donor bike. It’s in really good condition but I’m happy to have a go at converting to electric and then putting it back to gas later if it doesn’t turn out as expected. I know I need to cut the rea...

Re: Aprilia RS50 with 4kW QS-motor 17" rim

I’m looking at starting similar build with 4000w QS motor. I know yours is still work in progress but Can I ask what max speed you intend to get with your battery/controller combo?

Thanks

Re: My Electric Motorbike

I've been looking at importing one of these Chinese electric motorcycles into the UK. Can you tell me what the model is of yours?
