Re: Toughbox Torque

1. the only reason a bike system won't go in reverse is because the chain tensioner will only take up slack in one direction, and there is a one-way bearing on the input shaft to prevent loss of chain tension. The active chain tensioner is basically required because the sprocket size changes depending on gear. If you tensioned the chain in both directions, you could remove the one-way bearings and not worry about loss of tension in the chain.

2. Do you need 21 gears? I don't think so. We built a 4-speed in 2004, and we didn't really need more then 3 gears. It was automatic, and it hardly spent much time in 2nd before shifting to 3rd.

3. Have you heard of a CVT (Continuously Variable Transmission) and it's cousin, the Thunderchickens CCT (Crazy Chicken Transmission)?
