It's called pedalling.
Your feet are normally on the pedals.
Mechanical energy
Tricycle?
A freewheel will let the wheel roll forward w/o the pedals moving, but will pull on the pedals when the wheel is rolled backwards. A freecoaster hub can be rolled backwards w/o pulling on the pedals.
A free-coaster is a bike, or rather a special type of rear hub, that allows the bike to roll both backwards and forwards w/o the pedals moving. Most bikes can roll forward(=coast) w/o the pedals moving, but with a regular freewheel hub the pedals will begin to spin if you push the bike backwards. A freecoaster OTOH can roll backards w/o the pedals moving as well. Real important if you want to do trick riding that involves going backwards and pretty pointless otherwise.
The wheels against the ground, the axles against the wheels, the chain against the axles, the pedals against the chain, and your feet against the pedals.
No. The rider straddled the bike and kicked himsel forward with the feet on the ground.
The earliest forms of bicycles did not have pedals, they were pushed along by the feet of the seated person.
why did dinosaurs walk the planet, because they couldnt get their feet on the bicycle pedals
Basically, it's a pedal-driven paddle boat- the driver rotates a pair of pedals with their feet like bicycle pedals, which are linked by a connecting rod to one or two paddle wheels located between, or either side of, the pedals. This has the effect of powering the boat through the water.
You can connect any pedals of any brand. Its best if you seperate single pedals away from multi pedals.
It is not recommended, your feet can slip off the pedals and you can get hurt.
