Thanks for the info, however I'm much more interested in how much time and distance I can tweek out of an ebike rather than speed. The time and distance being complemented by my peddling. I found a LBS yesterday that has a trek fx+ for demo purposes but it was not charged. They asked that I stop back by and I will. I may not get the Trek FX+ but I do expect to either build or buy one with a similar setup sometime. I though as a comparison I would also test ride a non motorized top of the line Trek FX. Maybe the switch from my current bike, a 6 year old entry level ($500) fitness bike to a top of the line ($2000) is what I really hunger for. I might even put ebike idea on the shelf for a while and treat it as a project. I've sorta grown bored with building computers, OS, and networks.

again thanks for everyone's input
