Abstract:
A continuously variable transmission (CVT) can be used in concert with an electric motor to facilitate power assistance to a rider in a bicycle. In some embodiments, the CVT and motor is mounted on the frame of the bicycle at a location forward of the rear wheel hub of the bicycle. In some embodiments, the CVT is mounted on and supported by members of the bicycle frame such that the CVT is coaxial with the crankshaft of the bicycle. The crankshaft is configured to drive elements of the CVT, which are configured to operationally drive the traction rings and the traction planets. In some embodiments, the motor is configured to drive elements of the CVT. In other embodiments, the motor is configured to drive the crankshaft. Inventive component and subassemblies for such a CVT are disclosed.
Abstract:
A bicycle configured for communication with other bicycles, a centralized server, client computing devices and third party servers allows the rider to be connected with friends, coaches/trainers, and third party vendors including vendors associated with lodging, food, and other conveniences, vendors associated with bike servicing, equipment, warranties, and other bike related products and services, and vendors associated with routes, areas or destinations. Information may be communicated in real time or stored in memory and communicated to servers, client devices, other riders, etc., at a later date. Information may be communicated to the bike controller for route planning, service scheduling, training purposes and the like. Information communicated to or from the bicycle may be performed as indicated by the rider or there may be predetermined rules or guidelines for what information is collected and to whom the information may be sent to or received from.
