Fit a 2-stroke frame-mounted engine and a Ped-Power Sprocket to a popular mountain, road or hybrid style bicycle and you have transformed it into the ultimate all-purpose go-anywhere heavy duty power-assisted bicycle, which we'll call a Ped-Power Bike
Check out these features:
- Pedal power / freewheeling bicycle
- Pedal start engine / motorized bicycle
- Popular mountain, road or hybrid bicycles can be suitable host bicycle frames
- Pedal gears remain fully operable and independent of engine power transmission
- Unmodified commonly available bicycle wheels & hub
The ultimate all-purpose utility bicycle
Light enough to be used as a conventional bicycle, you can ride a Ped-Power Bike as a bicycle anywhere you can take a bicycle. As a bicycle, it weighs about 10 to 12 kilograms more than a conventional bicycle and you can live with that. Generally, that weight penalty makes little difference except for pedalling up hills.
You keep your full range of bicycle pedal gears. This means that you can pedal around just about anywhere including steep hills, pedestrian areas and bicycle paths.
As a motorized bike, it exhibits exactly the same features as a pedal-start Happy Time bike which is great for hills and long distance.
The Ped-Power Bike works best in conjunction with a good quality, well-maintained modern pedal derailleur transmission system.
Uses & Applications
The Ped-Power Bike comes into its own where a few difficult parts of your daily cycling routine would otherwise prevent you from being an everyday pedal cyclist. Here are some common everyday examples:
- Your home is a 20 kilometre highway ride from your workplace. This sort of distance would be beyond the limit of everyday endurance for most people, but not with a Ped-Power Bike. Pedal half the distance and you've had your daily quota of exercise. Its that simple.
- You live some distance up a mountain. Pedalling uphill is strenuous exercise, but on a Ped-Power Bike it becomes easy. There may be a few downhill sections as well, but who cares? You don't need to disengage the motor if you don't want to.
- You have a long downhill descent. On a Ped-Power Bike, disengage the motor and you can pedal downhill as fast as you can and save motor wear and fuel.
- How far can you ride your bike in 30 minutes? Maybe 10km? On a Ped-Power Bike you can double the distance and ride 20 kms.
Street-legal off-road/on-road motorized bicycle (Australia)?
The Ped-Power transmission system completely disengages the motor from the wheel. So, if you are pedaling along the street with the engine switched off and completely disengaged, where does it stand in legal terms?
I don't know, but it would be interesting to have it tested in court.
