Yeah you will have no thermal dramas single tracking it!liveforphysics said:I built it for riding single-track, and the power demands will be so much less off road it shouldn't have any thermal concerns. If it does have thermal drama off-road, FF and hubsinks should meaningfully help.
You may have to get creative to make the existing hubsinks fit due to the larger diameter but even FF alone should take care of it.
Even 10kw is too much most of the time on singletrack - as soon as you open the throttle you're instantly teleported towards the nearest tree at a rapid rate of knots and then hard on the brakes again. It's great fun to ride at the limit like that, but it's the limit of the trail, not the motor
Sketch and I rode some gnarly single track doing all the worst things you can to kill a hub motor - steep uphill climbs, switchbacks, low speeds, powering hard out of twisty turns dumping many kw straight into the windings at the motors least efficiency and with hubsinks and FF even mxus motors at 10+kw remained amazingly cool (we took IR temp readings at the top).
I really need to get the video uploaded because it's a great testimonial to what sort of punishment these motors can take with this cooling methods.
