Multi-person tricycle

1. A multi-person tricycle comprising:

three operable wheels, including two front drive wheels, and one rear steering wheel;

two front wheel drive assemblies, each front wheel drive assembly including a respective one of the front drive wheels, a rear wheel steering assembly operably connected to a steering mechanism, the rear wheel steering assembly including the rear steering wheel; and

a frame assembly integrally connecting said front wheel drive assemblies and said rear wheel steering assembly to thereby form said multi-person tricycle; and

a lockable/unlockable pedal connection assembly comprising a lockable and unlockable crank arm linkage assembly;

wherein the multi-person tricycle is configurable in an unlocked configuration in which each front wheel drive assembly including an independent drive train assembly, and in which the multi-person tricycle is configured or designed to enable at least two front-facing riders to each perform at least one action selected from a group consisting of: independently exert his or her own pedaling force; independently vary his or her own pedaling force; independently exert his or her own pedaling cadence; and independently vary his or her own pedaling cadence; and

wherein the multi-person tricycle is configurable in a locked configuration in which each front wheel drive assembly is mechanically coupled to the other, and in which the multi-person tricycle is configured or designed to enable one or more riders to each provide pedal torque which is transferred to the two front wheel drive assemblies.

2. The tricycle of claim 1 wherein each front wheel drive assembly including a respective plurality of pedals.

3. The tricycle of claim 1 wherein the steering mechanism is independently operable by each rider of the multi-person tricycle.

4. The tricycle of claim 1 being configured or designed to enable two front-facing riders to sit side-by-side.

5. The tricycle of claim 1 wherein differences in the pedaling forces and/or pedaling cadences of each respective rider does not substantially affect a direction of travel of the multi-person tricycle.

6. The tricycle of claim 1 wherein the steering mechanism is controllable by either or both riders of the multi-person tricycle.

7. The tricycle of claim 1 , wherein

wherein the three operable wheels are each configured to contact a road or surface while one or more riders are operating the tricycle.

8. The tricycle of claim 1 :

wherein the front wheel drive assemblies and rear wheel steering assembly are each configured to be removably connectable to the frame assembly to thereby facilitate ease of disassembly and assembly of the multi-person tricycle.

9. The tricycle of claim 1 wherein the lockable/unlockable pedal connection assembly is configured to provide functionality for mechanically coupling together the two independent drive train assemblies in a manner which provides the ability for any single rider to simultaneously power two or more independent drive trains; and which provides the ability for the at least two simultaneous riders to separately and independently power the respective drive trains by means of a dynamically adjustable coupling and decoupling mechanism.

10. The tricycle of claim 1 wherein the pedal connection assembly includes:

a right crank arm coupled to the crank arm linkage assembly;

a left crank arm coupled to the crank arm linkage assembly; and

wherein the pedal connection assembly is configurable in an unblocked or decoupled configuration, thereby decoupling the left and right crank arms, and allowing the left and right crank arms to rotate independently from each other;

and wherein the pedal connection assembly is configurable in locked or coupled configuration, thereby locking the relative positions of the left and right crank arms, and preventing the left and right crank arms from rotating independently from each other.
