I am guessing that most MC riders are interested in performance and in particular, stick-to-the-road performance, because unlike a car, any loss of traction on a bike will usually crash you (and there are no airbags). My suggestion would be to look at what other (production) EV bikes have done to get good range, Zero Motorcycles comes to mind.

Like many, they depend on the roll-back of the rubber piston seals as their "spring" to pull back just a tiny bit. Then the calipers are supposed to be floating on pins, so that the slight runout of the rotor and play in the wheel bearing are enough to push the pads away from the rotor. It doesn't work. The o-ring pullback is too little, the pad is just loose between the piston and rotor (and tends to lay against the spinning rotor), and the floating pins always rust up and won't move. > On Tire LRR common car tires are bad but MC tires are 2x's worse I > found on my Streamliner MC low CG chassis !!

Bicycle tires are obviously very good. What is different about motorcycle tires. Is there some fundamental reason for the higher rolling resistance, or is it just that the manufacturers don't bother (and customers don't care)? -- A designer knows he has achieved perfection not when there is nothing left to add, but when there is nothing left to take away. -- Antoine de Saint Exupery -- Lee Hart's EV projects are at http://www.sunrise-ev.com/LeesEVs.htm _______________________________________________ UNSUBSCRIBE: http://www.evdl.org/help/index.html#usub http://lists.evdl.org/listinfo.cgi/ev-evdl.org For EV drag racing discussion, please use NEDRA (http://groups.yahoo.com/group/NEDRA) _______________________________________________ UNSUBSCRIBE: http://www.evdl.org/help/index.html#usub http://lists.evdl.org/listinfo.cgi/ev-evdl.org For EV drag racing discussion, please use NEDRA (http://groups.yahoo.com/group/NEDRA)
