    Chainless Transmission

    anyone have any thoughts on the pros and cons of a chainless bicycle. This site has a bolt on chainless transmission that works with a Shimano Nexus 7 speed hub. It appears in the animation that it will be dificult to remove the rear wheel when this transmission id in place. http://www.sussex.com.tw/index.html

    Nothing is more efficient than a chain drive.
    Belt drive is closest, but still saps energy that could be going to drive the rear wheel. And a human can only put out 1/3 horsepower at best, so every loss is a big one.

    Actually, direct drive is more efficient.

    You're right about changing a rear flat. I had a customer bring a shaft drive in for that reason. I replaced the tube with a thorn proof and installed a Tuffy liner. However, he was charged $15 labor instead of the usual $6.
    Bikes use brakes to stop.

    If your bike has breaks, don't ride it.

    Wikipedia has a fairly balanced article on the subject:
