Abstract
A transportation device is disclosed. One aspect includes a rear assembly that further includes a rear frame, and a first rear wheel and a second rear wheel mounted to the rear frame. The rear assembly may also include a first electric motor and a second electric motor mechanically connected to the first rear wheel and the second rear wheel respectively, and an electrical power source comprising a battery, configured to power the first electric motor and the second electric motor. The transportation device may also include a front assembly that includes a saddle and a front wheel connected to the saddle via a wheel hub and a fork. An aspect includes an elastomeric torsional element connecting the front assembly and the rear assembly.
Claims24
A transportation device comprising:
- a rear assembly including:
- a rear frame;
- a first rear wheel and a second rear wheel mounted to the rear frame;
- a first electric motor and a second electric motor mechanically connected to the first rear wheel and the second rear wheel respectively, wherein the first electric motor and the second electric motor are configured to provide electrical assistance to a user of the transportation device;
- and
- an electrical power source comprising a battery, configured to power the first electric motor and the second electric motor;
- and
- a front assembly comprising:
- a saddle configured to support the user;
- a front wheel connected to the saddle via a wheel hub and a fork;
- and
- an elastomeric torsional element connecting the front assembly and the rear assembly, wherein the elastomeric torsional element is configured to permit a range of motion of the front assembly relative to the rear assembly, about a longitudinal axis referenced to the transportation device, and wherein the range of motion is constrained by a combination of one or more mechanical stops at the end of the range of motion, and an elastic force exerted by the elastomeric torsional element against the range of motion when the front assembly is moved away from a neutral position.
A transportation device comprising:
- a rear assembly including:
- a rear frame;
- a first rear wheel and a second rear wheel mounted to the rear frame;
- a first electric motor and a second electric motor mechanically connected to the first rear wheel and the second rear wheel respectively, wherein the first electric motor and the second electric motor are configured to provide electrical assistance to a user of the transportation device;
- and
- an electrical power source comprising a battery, configured to power the first electric motor and the second electric motor;
- and
- a front assembly mechanically connected to the rear assembly, the front assembly comprising:
- a saddle configured to support the user;
- a front wheel connected to the saddle via a wheel hub and a fork;
- and
- a pedal assembly configured to transfer mechanical inputs from the user to the front wheel, to propel the transportation device, wherein the pedal assembly is offset to a rearward position referenced to the wheel hub.
