That looked like an awesome ride ... what great scenery and what a great bike! Now you just need to duct tape a boom box on top of your battery box, hit the streets, and start blasting Judas Priest's "Breakin' the Law!" :twisted: Be sure to post the video here, this time WITH audio! :lol...

Miles, Just fantasizing here. You've probably figured out, I don't have the technical expertise, yet? to pull something like this off. You're right about the freewheel for the motor. Gotta have 2 or downhill coasting could really mess things up. Would you put the 2nd freewheel in between...

Miles, Your points are well taken. I like the shaft drive/Nuvinci concept for several reasons. The first primarily comes from my experience with admittedly less than high end chain bikes (Giant Iguana). The shifting on the bike was often a pain, particularly with upshifting. Sometimes it...

Ok ... here's my idea (more of a combination of ideas already in production). Forgive me if I'm a little loose with the terminology. Obviously, I'm leaving out specific controller, battery, and motor selection/specs. 1. Optibike style frame, motor location and internal batteries. 2...

Xyster, Unfortunately, I think you're right. I didn't realize the provisions being cited were CPRC. What's amusing to me is that bicycles that don't meet 750W, 20mph limitations are considered "hazardous substances."

I'm wondering if a state's enforcement of a law such as the Florida law that's been presented would be considered invalid due to a conflict with federal law and thus being in violation of the supremacy clause of the U.S. Constitution. Such a challenge would be further strengthened if it were...

As everyone has pointed out, the 20mph and 750w restrictions really make no sense. Why 20mph motor assisted power when people can get their bikes to 30+ without a motor? There's no limitation on the capability of a car/motorcycle's motor as far as how powerful they are or how fast they are...

Anybody try one of these? $325 or these? $225 http://www.zzipper.com/Products/prod_upright.php

First time poster here. This topic really grabbed me, since battery size, weight, cost, and durability seems to be the biggest limiting factor in e-bike performance. Here's a press release on the "32 Series Automotive Class Lithium Ionâ„¢ Cells" that was mentioned earlier. A123...
