Electric locomotion apparatus comprising: a dynamically stabilized vehicle having two wheels; said vehicle comprising a bar to allow said vehicle to steer on the basis of its rotation; characterized in that it comprises first and second support means of an ergonomic seat that are fixed to said vehicle; said first means being connected to said bar, so that a user's body movements to the right or to the left correspond to torsions of said bar and consequently allow said vehicle to steer.

A human-propellable vehicle (1) is described which comprises a chassis (2), and a rear wheel assembly (5) mounted to a rear portion of the chassis. The rear wheel assembly comprises a double wishbone suspension assembly, each wishbone (14, 22) of the double wishbone suspension assembly being coupled to the chassis at first and second coupling points, the second coupling point for each wishbone being closer to the rear of the chassis, and closer to the longitudinal axis of the vehicle, than the first coupling point for that wishbone. By using a double wishbone set up at the rear of the bike it is possible to control weight transfer more efficiently. By providing a second coupling point for each wishbone which is closer to the rear of the chassis, and closer to the longitudinal axis of the vehicle, than the first coupling point for that wishbone, it is possible to utilise a setup without having to adopt a higher seating position and without having to increase the rear wheel track beyond an acceptable width.

An apparatus for a wheelchair caddy to be attached to a disabled rider adapted cycle or scooter that may include connectors connecting the caddy and cycle, a rear or double rear axle attached to the base of the caddy frame, a handle for the user to grip while pulling the wheelchair onto the caddy, a rod as an emergency brake, a ratcheting strap or straps and bungee cord for securing the wheelchair in the caddy, walled footwells for the securing the passengers feet, a secured foam rubber middle console, a fitted, padded back rest, thigh restraining straps, lower ribcage restraining straps and other features.
