All those who love to ride a bike to work always hope that somehow the gravity lowers and they can ease their legs a little bit. While gravity won’t lower in any case, industrial designers Hoyoung Lee, Youngwoo Park and Jungmin Park have come to the rescue. They have designed a concept bike that literally levitates to reduce friction.



By using the impetus of the bicycle, power is generated and magnetism brings the rear of the bike up until the gear is in the center of the back wheel, connected only by the power of the magnets. As the speed increases, kinetic energy takes over and the rear of bike starts to climb upwards, which decreases wind resistance and absorbs the impact from stones and bumps.
