Abstract
Abstract A bicycle powered by electrical solenoids, one of which is linked by cable to each foot pedal of the conventional chain drive. Manually operated switches mounted on the bicycle handles control the operation of the solenoids. The solenoids are powered by a battery which may be charged by an alternator-generator when the bicycle is coasting or going down hill. The bicycle may be propelled by normal foot action on the pedals with the solenoids supplying additional power, as required.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
84 words
A bicycle which may be electrically propelled or operated in conventional fashion comprising a bicycle equipped with a foot pedal drive mechanism together with an electrical solenoid powered system, SAID SOLENOID POWERED SYSTEM INCORPORATING A SOLENOID FIXED TO THE BICYCLE FRAME, THE ARMATURE OF WHICH IS ATTACHED BY TENSION MEANS TO A FOOT PEDAL, SAID SOLENOID BEING ELECTRICALLY CONNECTED BY A MANUALLY OPERATED SWITCH TO A BATTERY, SUCH THAT CLOSING OF SAID SWITCH ENERGIZES THE SOLENOID TO EXERT PROPULSION FORCE ON SAID FOOT PEDAL.
