Yeah... It's funny...
This $2700 "kit" is just like any other yet is 3x's the price.
Its a 36v lipo pack of only 10ah. (if that bike falls on the ground the batts may explode)

Their $2000 "kit" at least integrates the battery into the rear wheel hub.

There's an ass for every seat, and this kit is for those who want to say, "look at me! I have $2700 to waste on something I could have bought ANYWHERE else for 1/3 the price!"
