Fix a note on the end of the rope that reads like this: "Please pull 500 ft until you get the power plug. Plug in. Thanks for supporting! Stryped". If you are back on power, you just go 1000 ft, use the momentum to tear the plug out and use up all the rest of inertia to go even further! When you come to a standstill, continue with slingshot. You can improve things, if you do have some long rubber band where one end is connected to your vehicle, the other end to the plug.

No need for a clutch or transmission, and the motor goes as fast as it wants to. Still would have to carry batteries, but it removes any potential for making the regular pedal drive excessively hard to pedal when off. |

I once fired up my combat control line plane with a screaming .40 with a
9-7 prop, layed it across the handlebar of my bike, gave a couple pedals to get rolling and rode around the block with that beast blowing castor oil in my face. Got up to decent speed on level ground but was slow off the mark. |

AH! But if you put the transformer (and wire) in a TRAILER then the bicycle will stay the same weight!!1 In fact, running with that logic, if the cyclist himself were to be seated in the trailer then the system would be even MORE efficient!!!! Of course! But the robotic controls and the associated processing equipment would surely outweigh the person pedaling the bike. NO NO NO!! You attach airfoils to the robotics to provide LIFT!! |

Only run the generator when you are not peddling so the power is free.

WHAT ?? there is a problem with that reasoning ??? ;-) Reverse the setup, power the coils, and you have a railgun. Actually, that could be the seed of an interesting idea. You would need to build some access bridges, but the technology is simple... Convert one HOV lane on a freeway to bicycles only and barricade it off from other traffic. One freeway lane could probably fit four bike lanes, two in each direction. Put four lines of your coils in the roadway, equip the bikes with a drop-down metal plate, magnet, or coil, and phase the energising of the road coils to power the bikes at 25 mph. Since the bikes would be forced into traveling at a constant rate of speed relative to each other, and have to center over the energised coils, accidents would be minimized and there would be no traffic jams caused by "slowpoke" drivers. Make a covered recumbant bike to keep the elements off the rider, and a lot of commuters would be interested. With stops and traffic, busses have an average speed that is often less than what this setup would allow. Freeways in most major cities get to gridlock during rush hours, making this type of transportation faster and cheaper. Pollution and noise is taken out of city centers and moved to more efficient (and possibly environmentally friendly) power plants. There is no physical connection or moving parts within the powering coils, so they should last as long as the roadway. The lighter bike frames cutting through the air at a slower speed than cars reduces energy use. The cost of building a bike with no onboard motor is less than building a car or motorcycle. Parking lots could double or triple capacity. |

There is an Ohlson & Rice bicycle motor listed on Ebay.
