Of all the ideas I've had for inventions this is the one that I'd like to have most right now. There are similar designs/concepts out there right now (though not widely for sale) but they all have one problem; they speed governed to a limit of 25mph so that you don't need a motorcycle license to operate one. Well that's just dum. You can go faster than 25mph on a regular bike in many situations. What is the point of having an electric motor added if it doesn't go any faster? Exactly there is none - so - here is my bike.
Speed: minimum able to do highway travel (meaning 85mph) and power sufficient for mountain riding.
Electric generators: 1 A regenerative braking system. 2 In-wheel generators (that operate whenever the wheels are in motion coasting or otherwise). 3 Solar generator (not much required just to power on board electronics). 4 Pedal generators (self explanatory). 5 Drive motor (when not in drive mode acts as an additional generator). 6 Plug in ( enables a recharge from your house power grid or equivalent).
Power storage: Fuel cell/battery/?? (rechargeable light-weight-ish)
Range: Unlimited as long as you can keep pedalling; the battery (or whatever) should be able to provide a range of 50-70 miles un-assisted by pedalling.
Drive modes: Electric drive or Pedal only
Pedal only mode:This is fairly simple you pedal just like any bike and the generators charge the battery.
Electric drive mode: There is a little more to this (though its not complicated/difficult) First, obviously the drive motor provides the propulsion (vs. your pedalling). A hand throttle would control acceleration/deceleration; when released to the neutral position an automatic cruise control would kick in maintaining the current speed. As long as you kept pedalling that is; because your pedalling is the 'go' command to the drive motor. If you were to quite pedalling the drive motor would quit driving the bike as switch to recovering energy; it would resume driving when you resumed pedalling (though it would maintain the speed you were traveling at when you resumed pedalling).
A flick of the throttle to decelerate (and back to neutral) would also switch the drive motor to recovery mode. Thereby allowing you to coast and decelerate while continuing to pedal. Accelerating the throttle will reengage the drive motor. Any activation of the brakes disengages the drive motor.
