Human muscles are developed for walking and not for circular pedalling. As a result, cyclists experience a “dead spot” of about ±15 degrees around the top and bottom of the pedal path. Several products such as ovoid chain rings that were marketed in the 90s tried to address this problem with poor success or bad side-effects. E-HUB solves this problem once and for all with a unique patented spring mechanism in the hub that overcomes the dead spots while allowing the cyclist to keep her/his usual rhythm.
