Abstract

An electric tricycle with a tricycle frame, at least two pedals, and an electric motor. The tricycle frame has a steering assembly with handlebars and a front wheel and a rear wheel assembly with two rear wheels mounted on a rear axle. The pedals are rotatably coupled to the rear wheel assembly. The pedals have an engaged configuration where the pedals are engaged with the rear axle and a disengaged configuration where the pedals are disengaged from the rear axles. The electric motor is mounted on the rear wheel assembly and is electrically coupled to a battery. The electric motor is configured to engage with the rear axle when the pedals are in the disengaged configuration. The electric motor may have a forward clutch to rotate the rear axle in a first direction and a reverse clutch to rotate the rear axle in a second direction opposite the first direction.

a tricycle frame having a front end coupled to a steering assembly, the steering assembly having handlebars and only one front wheel, and a rear end coupled to a rear wheel assembly, the rear wheel assembly having two rear wheels mounted on a rear axle;
at least two pedals rotatably coupled to the rear wheel assembly, the at least two pedals having an engaged configuration wherein the at least two pedals are engaged with the rear axle and configured to move in a reciprocating motion and rotate the rear axle in a first direction, and a disengaged configuration wherein each of the at least two pedals is disengaged from the rear axle, fixed in relation to the tricycle frame, and aligned with another of the at least two pedals;
and
an electric motor mounted on the rear wheel assembly, electrically coupled to a battery, and configured to engage with the rear axle when the at least two pedals are in the disengaged configuration, the electric motor having a forward clutch configured to rotate the rear axle in the first direction and a reverse clutch configured to rotate the rear axle in a second direction opposite the first direction, wherein the reverse clutch has a plurality of sprags wrapped with a continuous spring, wherein the continuous spring biases the plurality of sprags to a retracted position and when the reverse clutch is engaged, the plurality of sprags is in an extended position wherein each sprag of the plurality of sprags is positioned radially outward from the retracted position.
