Abstract
Abstract A tricycle is provided with a battery-powered drive motor as well as pedal-operated drive means so connected that either of the drive means may be used alone or may be used in combination to supplement each other. Both drive means supply power to the rear axle and the rear wheels are mounted so as to rotate at different speeds when the tricycle is being turned.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
235 words
A cycle including a frame; first wheel means; means defining a first rotational axis for said first wheel means; said first axis being mounted to said frame at one end thereof for relative pivotal motion about a generally vertical axis; second wheel means; means defining a second rotational axis for said second wheel means; said second axis being mounted to said frame in fixed position relative thereto and disposed at the other end thereof; pedal means rotatably mounted on said frame for supplying foot power to rotate said second wheel means; a battery and an electric motor on said frame for providing additional power to rotate said second wheel means; control means selectively operable to control energization of said motor by said battery; means connecting said pedal means and said motor to said second means to selectively power the latter at any given time from the combination of said pedal means and said moTor, or from either of them while the other remains inactive; said second wheel means including first and second wheels mounted for rotation at different speeds while said cycle is turning; said means defining said second rotational axis including a split axle comprising first and second independently rotatable axially aligned sections; said pedal means operatively connected to said first section to supply power to said first wheel; said motor operatively connected to said second section to supply power to said second wheel.
Claim 2
Dependent Claim
235 words
A cycle including a frame; first wheel means; means defining a first rotational axis for said first wheel means; said first axis being mounted to said frame at one end thereof for relative pivotal motion about a generally vertical axis; second wheel means; means defining a second rotational axis for said second wheel means; said second axis being mounted to said frame in fixed position relative thereto and disposed at the other end thereof; pedal means rotatably mounted on said frame for supplying foot power to rotate said second wheel means; a battery and an electric motor on said frame for providing additional power to rotate said second wheel means; control means selectively operable to control energization of said motor by said battery; means connecting said pedal means and said motor to said second means to selectively power the latter at any given time from the combination of said pedal means and said moTor, or from either of them while the other remains inactive; said second wheel means including first and second wheels mounted for rotation at different speeds while said cycle is turning; said means defining said second rotational axis including a split axle comprising first and second independently rotatable axially aligned sections; said pedal means operatively connected to said first section to supply power to said first wheel; said motor operatively connected to said second section to supply power to said second wheel.
Claim 3
Dependent Claim
27 words
A cycle as set forth in claim 1, in which there is an overrunning clutch connecting said pedal means to said first section of said split axle.
Claim 4
Dependent Claim
35 words
A cycle as set forth in claim 1, in which there is a seat mounted to said frame in front of said second rotational axis; both said battery and said motor positioned behind said seat.
Claim 5
Dependent Claim
24 words
A cycle as set forth in claim 3, in which said first wheel means comprises a single wheel positioned in front of said seat.
