#2132: Bisawcle

Today’s invention is a way to provide almost any old bicycle with two-wheel drive.

Both the front and rear wheel would be fitted with a drive sprocket on the end of each axle and the ordinary chain removed.

A couple of chainsaws would be clamped to the frame and forks as shown, so that the above sprockets engaged with the distal wheel on each saw.

Throttle cables would run from both machines to the handlerbars, where the rider could learn to maintain some control as the bike traversed even slippery and uneven terrain.
