This past weekend I purchased the bike from a local bike shop. I decided to buy the Specialized RockHopper Sport 29er (
one model up from the base RockHopper) because this bike has hydraulic brakes. I figure hydraulic brakes should preform better over mechanical brakes when braking from high speeds.
I estimate that I should have the bike completely built and functional in about 2 weeks. Once complete I'll be riding it 70 miles a day (35 miles each way to work). I plan to use a combination of pedal assist and motor only. I would like to be able to maintain an average speed of 25-30mph on the flats. I will do some testing on watt usage as soon as I finish building the bike.
