Any idea what kind of cells are in the Battery? What the Battery Warranty will be? What will be the cost of a replacement Battery? I believe 20mph will sell well, not so sure about 15mph in the USA. I just read a review of this “kit” that will be integrated into the Electra Townie, but light on specifics about the motor and battery/controller. Says they will be available Feb 2013 with some models already “seeded”. I hope it’s a huge success because ordering from China takes forever and it’s not a viable option if something goes wrong. But Batteries life span and cost will make or break it in the USA. I rode one of the first Chrysler E-bikes about a decade ago and it was a heavy slow dog of a bike with about an 8 mile range. So all that Chrysler proved was they couldn’t produce a ready for market e-bike. Hope this one gets the industry moving in the US. Now if someone would just bring to market a nicely constructed/engineered mid drive system for all bikes so that torque and weight distribution were less of a problem.

I like being the engine, but I think the majority of humans prefer whatever assistance they can get. I think the line ought to be drawn on speed – energy = velocity squared – so a bike limited in speed could use any power and be no more dangerous to cyclists than any other bike. Of course you’ll get a cottage industry turning 10 mph wussery into little crotch rockettes.

I’ve run a wisper (a UK electric/pedelec) for a few years now. I live at the top of a huge hill, and I can bike to work any day there isn’t a good frost. I’ve lost over 30kg, and never ever felt better. I’m exactly the target market you describe. 10ah seems a bit low. Its not about power or going faster, but further.
