When you try to ride a bike with the pedals moving only backwards and not forward, the bike will not move forward. The pedals need to move in a forward motion in order for the bike to propel forward.
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.
A freewheel in the rear hub is designed to let the bicycle coast forward without the pedals going round and round. Because of the freewheel, pedaling backwards also disconnects the pedals from the hub.
To move forward on a bike, you should turn the pedals in a clockwise direction.
Pedals on a bicycle are attached to the crank arms and are used to transfer the rider's energy into forward motion. When the rider pushes down on the pedals, the crank arms rotate, which turns the chain and ultimately drives the rear wheel. Pedals allow the rider to propel the bicycle forward by applying force with their feet in a circular motion.
To propel a bike forward using the pedals, you push down on the pedal with your foot, applying force to turn the crankset. This motion transfers power to the chain, which then rotates the rear wheel, propelling the bike forward.
It's called pedalling.
Putting weight on the forward pedals puts tension on the chain, which rotates the rear wheel and pushes the bike forward.
Mechanical energy
There could be several reasons why your bike pedals won't move forward. Some common causes include a loose chain, a malfunctioning gear system, or a problem with the pedals themselves. It's best to have a professional bike mechanic inspect and repair your bike to determine the exact issue.
The drivetrain on a bike consists of the chain, gears, and pedals that work together to transfer power from the rider's legs to the wheels, propelling the bicycle forward. When the rider pedals, the chain moves along the gears, causing the wheels to turn and move the bike forward.
A bike uses energy to propel forward by converting the energy from the rider's pedaling into kinetic energy. When the rider pedals, the chain transfers the energy to the wheels, causing them to turn and move the bike forward. This process is powered by the rider's muscles and the force they exert on the pedals.
