Re: QSMOTOR,0.5-12kW Electric Hub Motor & Mid Drive Motor Manufacture China

Hello, my 205 50H V3 looks like it moves around on the sprocket side. When I speed up the motor with no load, it vibrates like its out of balance. Ive removed the covers to check that the bearings are seated and to see if I could fix it by reinstalling the covers bit its never fixed. Its possible t...

That three wheeler and that motor with those small wheels - it will be crazy to the point of not being driveable :wink:
Sounds just like my cup of tea, that thing, that amount of power sounds about right for anything. :D

Re: QSMOTOR,0.5-12kW Electric Hub Motor & Mid Drive Motor Manufacture China

To bad the wires comes out in the back, right at the feet on a motorcycle. To the side would be so much better, it can be at the edge next to the backplate. I agree, maybe not a cable routing that will ensure longevity and reliability? Would be a very sad day if bikes hit the ground while boondocki...

Re: QSMOTOR,0.5-12kW Electric Hub Motor & Mid Drive Motor Manufacture China

Very nice. That 180 must be an amazing motor. I've think I got a candidate for a possible controller fo rthe 180. But its summer, and the email response time are a bit slow. I think in a week or two I will know if that controller will work. If the engineers need any more motor data to see if they be...

Re: Nucular electronics - complete kit for ev! [beta]

My question is does it retain all of my existing settings, so I don't have to worry about wheel off the ground as well as writing down all my settings to duplicate? When I did it last time, it wiped the settings. You can export the current settings to the memory card first. Then import them after y...

But I don't think that will happen any day soon. I am for sure not sinking north of 10 000$ like the ready one ships for tod...

Re: KTM 200 exc goes electric

Regarding the rear sprocket, could you make it a two piece? Where the center part is hi grade aluminum and is mounted on the hub, and the steel outer part of the sprocket - the part with the teeth bolts onto the inner part? I remember the first big brake kits that where available for hi powered cars...

Re: SilentEnduro conversions

Not really sure what you are asking but I will try to answer my best. Both the 205 and the 138 can perform much more the the rated 3000 w. The 205 is often seen as a hub motor but it can be used as a mid engine too. One bike that uses a hub motor in a mid motor setup is the Vortex from Vector ebike....

Orlov got his hands on a nice looking e-moto a few weeks ago.. https://www.youtube.com/watch?v=_mhMqbLZ8zM seems like a very fair review.

Re: Sur-Ron - New Mid drive Bike

KTM E-XC is heavy at 245lbs. I have a Zero FX but like the Sur-Ron much better on tight single track trails because of the light weight, power isn't everything. And I've had KTM's, 360 2 stroke and 640 ADV. Better suspension and more power than the FX but electric wins for me. A new entry is the Ub...

Re: Denzel 72v 4-spd Gearbox Build 125cc Dual Sport

its just very odd how reduced the performance was when it reached its thermal limit, almost like the magnets had no energy left in them
That could very well be the case, maybe motor got too hot and the magnets got de-magnetized?
