Re: 1970 Vespa 50s electrification project

Awesome looking project! Love the welder and the workshop setup you got going on. Definitely have the skillset to make a successful conversion. It's cool what you did with that half of the stock chainstay/swingarm. That's gonna be a fabulous whip. I think I briefly had the same QS 4kW 10" V3 motor a...

Re: Need help figuring out a controller

It sounds to me like you're being artificially restricted by the controller, or else 48V is not enough to go very fast. You could replace the controller with something better, maybe from Kelly. Otherwise, figure out how to bypass the speed governor. On my original controller (similar looking to your...

Re: Advice on upgrading rear hub motor in Gigabyke E-scooter

So do you know what controller you have on the scoot? There's a chance it's strong enough, but you're right, move it to the bicycle and go higher power for the scoot if you can. Then you'd have a couple of cool whips by the end. Regarding your motor, that new one you linked is only 1500W. That's a b...

Re: Advice on upgrading rear hub motor in Gigabyke E-scooter

Do you know what the current and voltage limits are on your controller? It would be good to regard those in order to determine if you want to replace that part. Otherwise, you are constrained to those limits in choosing battery/motor. Regarding the motor, Voltron shows a good example of what you cou...

Re: Hub drive vs Chain drive

Yeah, it's for full-sized motorcycles. It's the latest and strongest mass-produced QS motor. It would be nuts on a scoot. You'd want to use something like a 180/55 tire on it, even though the default rim width is 114m (4.5"), but they'll customise it for you. Otherwise, no traction because the conta...

Re: Fazer Conversion Completed

Yikes, that's some bum luck man. I wonder what controller you're using exactly (e.g. KLS14401...). Did you overvolt the controller, e.g. run 108V on a 96V controller? I could see overcurrent being an issue too, as that happened to me before. I think it's good to dial a Kelly back down a bit, or else...

Re: Hoverboard & motorcycle hub motors MAXIMUM load?

Oh. So, you want to use hoverboard hubs on your one-wheel, and you're asking about max load on the QS as a separate project. Okay. So two projects. For the one-wheel using hoverboard motors, you may post the details of the motor. Diameter, wire gauge, wattage, voltage winding, width, anything else. ...

Re: Hoverboard & motorcycle hub motors MAXIMUM load?

The maximum load for the hoverboard motor depends on the exact motor in question. This is assuming the batteries and controller are not the bottleneck (though on a typical hoverboard, they are likely to be). The QS motor can move more weight than you'd ever need to move on a hoverboard. They are mea...

Seconding what these posters have already said. Don't waste your time trying to repurpose that kind of tech.

Controller and battery is exactly the same?

I'm sad because I think I killed my 8kW QS hub motor yesterday. See pics on my build thread here . I need a replacement that's more able to handle high power levels, like 20-40kW bursts (maybe as high as 50-60kW). Torn between chain-driven and hub motors now. I wonder what the best chain-driven moto...

Smeagol, your build is looking great. +1 for QS product quality. They're really cool guys. I used to have the same motor as you but I traded it up for a slightly larger, 72-120V 8kW version. I think they under-rate their product too since my 8kW motor is being run waaaaay past its redline. My only g...

Dude, good luck building an app for that. Although my bluetooth is working fine, I'd be interested in your results because I see a lot of potential.

You have a KEB... I have a KLS. They don't have bluetooth for KEB? That's unfortunate. It seems they also don't have an Android program.
