Reduce your carbon footprint and increase your “I am a dork” factor by jumping on the latest clean & green trend: Lawnmower Bicycles. Back in my day, you had to push one of these things around with your hands. Now you can hook your Brill Razorcut Mower to the back of your Lamborghini Forza Mountain Bike and get the same choppy, uneven looking lawn in a fraction of the time. The main thing I remember about manual mowers was the way they would randomly seize up when you had some good momentum going and slam to a stop with the exact amount of force required to break your wrists. Who knows what the effect would be at 15 mph. Probably multiple contusions and lacerations to the hands and face. To avoid all these potential injuries, you might try one of these innovative devices instead.
