Nathan Womack is a serious bike rider, serious enough that he wanted to ride at a
training pace on rides with his girlfriend. The trouble was that his
preferred pace for training for triathalons was about 20 mph, and his
girlfriend’s pace is more like 15 mph. He had the bright idea of making a
wheel that would give him some resistance in his rides, so that his speed would
equal his girlfriends speed, yet give him the training he wanted.
His solution developed into a bike product called the SlowWheel. The SlowWheel is a replacement rear wheel for a bicycle that allows the rider to increase the resistance of the wheel (in order to slow the rider down). Using the SlowWheel, Nathan and his girlfriend are able to ride together, and both get a workout! The wheel can also be set to no resistance at all, for maximum speed.
Additionally, Nathan looks to have a children's model out (for children under 5) that will go on a small bike with training wheels to help "slow" the child down as they learn to ride a bike. This will help in coordination as well as be an incredible safety device (as the children will not be able to get going so fast they get out of control).
