Spring Bike: Push Bike impulsed by the Separation of the Support Points

This innovative bicycle design eliminates pedals, instead allowing users to propel the bike forward by stretching their upper body against a resistance spring. The flexible frame enables separation between support points on the saddle and handlebars, which generates motion through a mechanical system. This concept offers various advantages over traditional bikes; it provides a more complete exercise by engaging the entire body, attracts young children as an intermediate step before pedal bikes, and is comfortable for elderly or physically challenged individuals due to its secure design and support of body weight. In urban settings, this bike is more comfortable for starting and stopping, as well as navigating stairs and ramps, thanks to the lack of pedals hindering movement. The handlebar can be narrower, further increasing compactness. An additional advantage is the ability to incorporate power-assisted drive systems by associating a torque sensor with the traction spring. This unique design concept could also be applied to KickScooters and Skateboards, making it an attractive alternative for various transportation needs.
