Craig Smith of Milwaukee, Wisconsin, made a snowplow that he can drive with a modified bicycle:
A lever pulls up or lets down the plow with a rope and pulley. Pulling the lever all the way back cantilevers the rope and pivot point so it locks in place. The plow blade is hinged with a bungee cord, so hitting a discrepancy in the road allows the blade to flop and give like a real plow. The bike can turn on a dime so raising the plow and returning up the adjacent path is quick and easy. I can do ‘reverse’ by pushing down on the front wheel with my foot to roll it backwards.Totally useless with larger snow falls, but the light ones make snow removal fun.

Rob Klinkey built this remote-controlled snowplow. Roboplow has a 50 inch blade, six powered wheels, and 660 amps of power. The blade can be pneumatically controlled in four directions. Lights and a mounted camera allow the Roboplow to be driven while out of sight and at night.
