Abstract
A combination pedal and motor powered bicycle "moped" having a chain tension sensor attached to the throttle so that the rider can control the power output of the motor by the degree of force he exerts in pedalling.
Claims12
A vehicle having at least one traction wheel and foot peddling exercise means connectable to said wheel comprising:
- motor operated power means providing motive power for said vehicle;
- control means for variably controlling the effective motive power output of said motor operated power means to drive said vehicle at variable speed;
- said foot pedalling exercise means including a pair of pedals operable by the application of pumping force thereto by the vehicle operator;
- drive means for connecting said exercise means said traction wheel to apply as motive power thereto independently of said motor operated power means, the pumping force exerted by the operator on said exercise means;
- force sensing means for sensing the pumping force applied by the operator to said pedals independently of the pumping speed thereof;
- and
- connecting means for connecting said force sensing means to actuate said control means to vary the effective motive power output from said motor operated power means responsive to varying operator pumping force applied to said pedals for driving said vehicle at varying speed while said exercise means and said traction wheel are connected by said drive means.

A vehicle having at least one traction wheel and operator exercise apparatus connected thereto, comprising:
- motor operated power means providing motive power for said vehicle;
- control means for controlling the effective power output of said motor operated power means;
- manual actuating means for said control means;
- foot pedalling exercise means including chain and sprocket means for application of vehicle operator applied force thereto;
- drive means for connecting said exercise means to said traction wheel to apply directly as motive power thereto the pumping force exerted by the operator on said exercise means;
- force sensing means for sensing the tension of said chain for said manually operable exercise means;
- and
- selection means for selective operation of said control means by said force sensing means in an exercise mode;
- said force sensing means in said exercise mode sensing the tension of said chain and being connected to said control means for varying the power output from said motor operated power means responsive to varying operator force applied to said foot pedal exercise means while said pumping force is simultaneously applied directly to said traction wheel.
