I'll try to get a shot of the uppers tomorrow or Monday - it's up in a friend's garage a few miles from home atm - but here's the lowers. Somewhat strange how they adapted a motorcycle fork to mate up with a car wheel, but I guess that's to make it easy to carry a spare that can swap to any of...

It took a while for my trike to make it across the ocean, and it's taking another while to get it into road-worthy shape, but it's almost there. The forks on this thing are massive. 51mm tubes, and a 32mm axle! QSMotor axles are "only" 18mm, and I briefly considered mounting the motor with...

Hey, thanks! I never would have thought of dividing a large battery pack, usually I'm trying to do the opposite! And a factory EV battery is probably composed of matched cells, so maybe I could parallel the divided strings, assuming they're not already and there's not too many bad cells. The...

1 month update, I've paid for the GO-4 and have title in hand, just waiting for it to make it across the ocean. Looks like it'll be another month before I finally get my hands on it to take measurements on the forks. But, since batteries will likely be the most expensive component and January...

Yes, empty about 1500 pounds! I figure I'd want at least 3 kW to cruise through the neighbourhood at 10 MPH. With one of the big 8000W QS motors maybe I could even cruise through town at 20 MPH - and yes people actually drive that slow here. Hm, yes sourcing an ideal controller might be...

I do know more about programming than I do about electronics, but I'll have to do some more research into either. In the meantime, the cable-actuated electronic throttle combined with a generous LVC sounds like it'd be a quick way to have the right throttle working both. I was thinking two...

Right, I see that they do. It's just that all the dual-sided-axle motors they have seem to have the same tiny threaded axle, so if that's not strong enough they'd have to do something custom, if they even would. I'm aware of the holiday and in no rush :-) It'll probably be a few weeks before I...

Basic premise: Slap a hub motor on to the front a Westward Industries GO-4 Interceptor. My experience: Back in 2011 I built an e-bike out of a tandem with a 9C kit from ebikes.ca and four lead-acid batteries. I've also done a lot of mechanical, fibreglass, and brazing work on motorcycles; and...

Hi, I'm interested to see if a QS motor could be good for a utility trike. • Motorcycle-style front fork clamps on axle • 155/80-13 tire, or could do a wider tire with 12" rim • Ideally, 16 rpm/v for 60V battery, or 13.3 rpm/v for 72V battery • Front GAWR is 675 lbs. • 3000 W minimum, but the...

Oh, nothing that fancy, I just mean whether I've got the throttle on or not. My old e-bike's motor would get up to 45 at 48 volts, but if I was headed down a hill faster than that it became a drag. I just mean the windings, I'm running 58 volts, so I wouldn't want a motor designed to need 72...

Aloha, I've been wanting create a hybrid electric moped out of my Tomos for almost four years now. To do this with my bike, I need a hub motor that can accept a left-hand drive freewheel. I have been searching and searching but have not found anyone who makes one, just one youtube video of...
