Now sold. Used but in working condition and recently tested. Bought for an electric motorbike conversion project that I’ve had a change of plan on, and so am now selling the Turnigy packs (16x - see separate listing at £150) together with this charger that I’d bought for charging the packs. Looking ...

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

The build has finally begun after collecting all the parts together. First off I got a battery box fabricated to hold the LIPO packs (16 packs, giving a 20s4p configuration). https://i.ibb.co/Gsd1C73/679-BE6-C5-9-E4-E-4-EE8-811-B-C5961-BB3066-E.jpg It’s a bit of tight fit but there’s sufficient spac...

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

Thanks for the info. I think I’m going to go 120/80 17 as this looks closest to the original Aprilia in terms of fitting in swingarm plus my QSMotor rim width is only 3.5” I am struggling a bit finding a local MC tyre shop who will fit for me given the fixed axle on the hub motor wheel.I can have a ...

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

Edit: I can also source a 120/80 tyre which I think will be closer still to the original Aprilia rear wheel/tyre.

Still be good to know what tyre you used here.

Many thanks

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

Hi Manny I’m just looking at getting a tyre fitted to my QSMotor 17” rear wheel/hub motor and I’ve discovered that 120/70 r17 tyres are really just spec’d for front fittment now only. This gives me an issue with insurance in the UK market if I fit this to a rear wheel. Can I ask - did you manage to ...

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

Motor and controller turned up at the end of last week. I must say I was very impressed with the whole experience dealing with QS Motor (Robert Chen) and the great packaging. Everything looks good quality as I took it out of the boxes. https://i.ibb.co/2yNvsSz/9-E863-BDF-0230-4510-BE26-D68-C876-EC07...

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

I’ve decided to build the Aprilia up first using some small LiPo packs that whilst they will only give me a small range it will be enough to get the bike up and running and the registration changes made. I can then also better see what the Amp draw is on the battery pack for the speeds I’m designing...

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

Thanks for the heads up on the Samsung 30Q cells - I’ve looked into these more and I can see how they aren’t great at holding charge if you zap them at much more than 2C. I’m really struggling here to find something that is relative safe (not Lipo), close to being reasonable cost (not Graphene) and ...

Re: CA V3 or V2.23 SA

Thanks for the feedback - I had the same comments back from Robert at QSMotor about 150A being a bit small so we’ve upgraded the order to the 200A version

Thanks for all the feedback I’ve received which I’ve taken onboard and changed my controller and also revised the batter pack spec.

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

Ok but can you help me understand what it is with the spec given the cells are 10c and it’s been tested at 60a continuous for 20mins without any sag? Also the BMS in the module is just for balancing on charging so I can use my own BMS or rely on the controller to limit voltage and display etc to mon...

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

I’ve gone back to look at the Valence Power u-Charge pack. These are LifePO4 cells with each module made up of 144 cells. I can source 2 modules that are 38.4v/30AH each which in series would give me 76.8v / 30AH. The vendor tells me that the cells are rated at 10C and they have run a 20 minute test...

Thanks for the pictures - yes I have to machine some plates anyway for fitting the motor to the Aprilia Swingarm. I’ve already sourced another swingarm that I will use off the bike to design the mounts. I will check with Robert at QSMotor if the mounts come with it but as you say they probably won’t...

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.

Hi I’m planning the build of an electric conversion of an Aprilia RS50 moped using a QS Motor 17” hub motor.

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...
