Range depends on batteries.
Since this bike is using lithium polymer it can go farther with less weight than any nicd or nimh bike with the same setup.
Decently priced 20AH lipoly packs are not too far off.
Before I purchase or make a production Ebike it needs to go 20mph+, have good low end, be brushless, silent, use lipolys, charge in an hour and not cost a rediculous amount of money.
Going through the gear is mandatory if it is proven even the best hubs or outrunner setups can't beat the efficiency or if hubs don't freewheel without the magnets cogging and slowing you down etc...
