Sunkyong Bicycle Mower
This thing seemed like a good idea to Hammacher-Schlemmer back in 1985. The mail-order company known for esoteric and extravagant gadgets (anyone looking for gold-plated barbeque tongs or a personal submarine?) offered the SK Mower to lawn enthusiasts who were tired of breathing gas fumes as they mowed.
A pedal-powered lawn mower has been the dream of garage mechanics for a hundred years now. Usually the idea would take the form of a reel-style push mower bolted to the front of a Schwinn Stingray. The Sunkyong corporation decided to put some engineering into this idea and came up with the SK Mower.
The cycle mower is ideal for homeowners with a ten foot by twenty foot perfectly flat yard. No, I take that back. It isn’t ideal for anyone. Wet Seattle grass stops this bike in its tracks. The gear ratio is so small that it would take Lance Armstrong four hours to mow a putting green.

They found that the 3.8 inch gear ratio meant for a long day of mowing, as national team rider Thurlow Rogers spent the better part of a weekend trying to mow the Cyclist Magazine office lawn.
