Electric bicycle conversion kits

A kit of parts for providing electric motive power to a front sprocket assembly of a regular bicycle, the kit comprising:

• an electric motive power unit having an external freewheeling sprocket drive assembly extending therefrom, said sprocket drive assembly configured for demountable engagement with a bicycle chain on the bicycle;
• a rechargeable battery and battery mount for providing electric power to the electric motive power unit, said rechargeable battery and battery mount provided with a key for locking and unlocking the rechargeable battery to and from the battery mount;
• a mount bracket for demountably engaging therein the electric motive power unit and for demountably engaging there onto the battery mount, said mount bracket configured for demountable engagement with a down tube element of the bicycle, said mount bracket configured to demountably engage to a top portion of the battery mount;
• a power cable in communication with an on/off switch and a demountable handlebar clamp, said power cable demountably engageable with the rechargeable battery and the battery mount;
• a quick-release throttle control assembly configured for demountable engagement with the bicycle's handlebar, said throttle control assembly provided with a microprocessor configured to monitor and process signals received from a wheel sensor and to modulate electrical motive power outputs from the electric motive power unit in response to changes in the signals received from the wheel sensor;
• and
• a communication cable configured for demountable engagement with the throttle control assembly, with the electric motive power unit, and with the wheel sensor,
• wherein the microprocessor provided for the throttle control assembly is additionally configured to monitor and process signals received from one or both of a gear ratio sensor and a cadence sensor, and to further modulate electrical motive power outputs from the electric motive power unit in response to changes in the signals received from the wheel sensor, the gear ratio sensor and/or the cadence sensor.
