Engineering Student Builds Flywheel Energy Recovery Into Bike

Max von Stein's flywheel bicycle is everywhere these days. The engineering student first demonstrated it at the Cooper Union year-end show. ArchPaper described it: Engineering student Maxwell von Stein applied the principles of a hybrid car to the bicycle to harness the kinetic energy typically lost when braking. With a variable transmission and a flywheel mounted to the bike's frame, von Stein's...
