i just got the rail 9.8XT for AU $11,799.00 . best investment i ever bought. too often people are trying to spend money to make more money, this is one of those things that's pure fun, the thing rides like a dream, all you have to do is pedal and the motor does pretty much the rest of the work. its 100% worth every cent..
can get a back pack which holds the spare battery centrally so it doesnt flop around as you carry it. This is the only way you can range extend these as far as i know
