From: Initial development of skill with a reversed bicycle and a case series of experienced riders

Skilled performance of experienced riders riding the reversed bicycle in Experiment 2. (A) Examples of handlebar oscillations for an Experienced rider riding both reversed and normal bicycles (reversed: last trial of Day 1; normal: last trial of Day 2). (B) Power spectra of handlebar oscillations. All four Experienced riders (E1-4) show lower power in all frequencies than the Fast Learners (10Ss). REV reversed bicycle, NORM normal bicycle.
