A wheel with a self-contained drive mechanism is provided to propel (or assist in propulsion of) bicycles, tricycles, and similar vehicles. The wheel preferably takes the form of a detachable wheel which is readily received within the dropouts of a bicycle frame or fork to be attached therein by a standard quick-release mechanism. Thus, the wheel may be added to (or removed from) preexisting standard bicycles and the like.

What is claimed is: 1. A wheel propulsion assembly for a bicycle having a steering column including a handlebar descending to a front fork, said fork having a pair of opposing legs, each leg having a lower dropout for receiving a wheel axle therein, said wheel propulsion assembly comprising: a. a wheel having a self-contained drive mechanism radially disposed within said wheel, said wheel further having a central wheel axle with wheel axle ends protruding from opposite sides of said wheel, said wheel axle ends being insertable within said lower dropouts of said fork legs for removable engagement therein; b. a restraining member affixed to said wheel axle between said fork legs, said restraining member: (1) extending from said wheel to an engagement end distant from said wheel axle and outside said wheel diameter, (2) being sized and configured such that when said wheel is situated between said fork legs with its wheel axle ends within said lower dropouts, the restraining member extends upwardly from said wheel to engage said handlebar at its engagement end; (3) said engagement end bears a pair of opposing stops, said stops defining a vertically open handlebar insertion slot therebetween, whereby said handlebar of said bicycle can be inserted within said insertion slot between said stops; c. a motor anchored to said restraining member, wherein said motor drives said wheel, wherein said wheel propulsion assembly is removably installable within said front fork of said bicycle by inserting said wheel axle ends within said lower dropouts of said fork legs and engaging said engagement end of said restraining member to said handlebar. 2. The wheel propulsion assembly of claim 1 wherein said stops are respaceable to allow adjustment of the sizing of said handlebar insertion slot. 3. The wheel propulsion assembly of claim 1 wherein said stops are arrayed in a row oriented at least substantially perpendicular to said wheel axle. 4. The wheel propulsion assembly of claim 1 wherein said engagement end of said restraining member bears three or more spaced stops arrayed to rest about opposing sides of said steering column. 5. The wheel propulsion assembly of claim 1 wherein said restraining member includes a pair of legs translatably affixed to each other, whereby the location of said engagement end may be adjusted with respect to said wheel axle. 6. The wheel propulsion assembly of claim 1 wherein said wheel axle ends bear quick-release couplings actuatable by hand to rapidly engage and disengage said fork legs at said lower dropouts. 7. The wheel propulsion assembly of claim 1 further comprising a throttle control on said restraining member adjacent its engagement end, said throttle control being in communication with said motor to adjust said motor's output. 8. The wheel propulsion assembly of claim 1 further comprising a display on said restraining member adjacent its engagement end, said display being in communication with one or more sensors receiving measurements from said motor or said wheel. 9. The wheel propulsion assembly of claim 1 further comprising a motor support bearing said motor, said motor support being anchored to said wheel axle and said restraining member. 10. The wheel propulsion assembly of claim 1 wherein said wheel is driven by frictional engagement with one or more rollers which engage said wheel. 11. The wheel propulsion assembly of claim 1 wherein said wheel is driven by engagement with one or more gears which engage said wheel. 12. The wheel propulsion assembly of 1 further comprising: a. a drive train transmitting rotational energy from said motor to said wheel, said drive train including one or more gears interposed between said motor and said wheel; b. a freewheel clutch situated in said drive train between said motor and said wheel, wherein (1) rotational energy is transmitted from said motor to said wheel as said motor is operating, and (2) rotational energy is not transmitted from said wheel to said motor while said motor is not operating. 13. The wheel propulsion assembly of claim 1 further comprising a roller: a. said roller being driven by said motor, said roller being frictionally engageable with said wheel; and b. said roller being orbitally anchored with respect to said restraining member, whereby said roller travels in an orbital path about said restraining member to move: (1) into contact with said wheel to frictionally engage and drive said wheel, and (2) away from said wheel into a disengaged state wherein it does not drive said wheel. 14. The wheel propulsion assembly of claim 13 wherein said roller is elastically urged about said restraining member into contact with said wheel to frictionally engage and drive said wheel. 15. The wheel propulsion assembly of claim 13 wherein said roller is borne on an arm which is a. pivotally affixed, and b. elastically biased with respect to said restraining member, with said arm being rotatable to move said roller into engagement with said wheel. 16. The wheel propulsion assembly of claim 13 further comprising a drive train interposed between said motor and said roller, wherein said drive train transfers rotational energy from said motor to said roller. 17. The wheel propulsion device of claim 1 further comprising an energy storage means for providing energy to said motor, said energy storage means being mounted on said wheel propulsion device at a fixed location relative to said lower dropouts when said wheel propulsion device has said axle ends removably connected within said lower dropouts. 18. The wheel propulsion device of claim 17 wherein the center of gravity of said energy storage means is below said lower dropouts.
