Aprilia RS50 with 4kW QS-motor 17" rim

[swiftyds]

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

my intended top speed is 80kmh but i think it will be a bit faster.

Hi Manny

May I ask what the dropout is in real life, with nuts, disc, spacers etc ? I think about a 4kw qs273 in my rear wheel ...

hi csc,

The measurements in this pdf are correct iirc.
hope this helps, if you need a specific measurement let me know
