I have read a lot of threads about making these things go faster etc... I think of these things too, but I have to remind myself that a motorised bicycle is a unique beast. Cool and special in it's unusual appearance and function. Anything we do to make it faster or last longer or pull more is simply an attempt to reinvent the motorcycle. It's been done! Honda, Kawasaki, Suzuki, BMW, Harley Davidson. They do it better than us. I understand some men just have to tinker and modify to see what they can accomplish. It's genetic. That's cool too. I revel in the unbelieving looks I get from people when I whiz by. I've got something people consider cool and almost no one else has. And I can trick it out with lots of inexpensive lights and blinkies, horns, bells, and whizbangers.... That rocks!!! But it's still a bicycle. A unique bicycle.
