So why does Sarah feel so comfortable on this bicycle so far above the ground? Well the net and the five point harness really help but there is no way for the bike to tip over or fall off that wire! Hanging beneath the bicycle is a 350 pound counter weight which keeps the bike right side up.
Even with the weight of Sarah combined with the bicycle, the counterweight weighs much more and will always be pulling the bike back into the upright position even if Sarah were to get very brave and rock the bike back and forth!
So why is the net there? Two reasons: It makes people feel better and shoes can still fall off or get dropped and those don't feel great when they land on someone standing on the main floor!
MOSI's High Wire Bike is the longest High Wire Bike ride in a US museum with a 98 foot long cable and is truly science in motion!
