I have made numerous bikes over the years but have not been fabricating for awhile. This summer in Japan I made my own Lawn Bike. I guess it is not a bike since it is a tricycle but it has about three inches of dirt and real live grass. The fence is to help keep the bad guys out. Because of the ninety degree bend in the chain line I used and extra free wheel to transfer the power from one chain to the rear dive chain.
It was hard to pedal because of the weight and it had to be watered daily and cut often. Too bad I had to leave it there when I returned to the states this fall. Never had a chance to barbecue on it as planned. I thought the forums might enjoy it.
