ok, who has some real power running thru a friction system ?
what are the percieved limits and pitfalls ?
yes, you know what i'm thinking - HEHEHE

My 43cc with velocity stack and manifold spacer was pretty pimped. Besides the operating pitfalls (i,e wet road) it worked great when dialed in. But the system required constant tweaking. Drive roller to tire gap, tweaking the drive roller PTO so the drive wheels would not lose power by spinning on the shaft, ect. An then there';s the dynamic of the tire being ground down and reshaped so the handling properties of the bike are constantly changing. And not for the better.
I differ with the statement that friction drive is "simple and light weight". Hogwash. GEBE is simple and light weight. I grin every time I look at my back tire which has seen 1000+ miles and it has the tread remaining of a friction drive that has gone 70- miles. I had to do a bit of engineering for my pimped motor to work with the GEBE drive ring but those efforts were minimal compared to the near constant thinking /wrenching on the friction to keep it at peak performance.
