Gas Bicycle

Is a small rear sprocket take more gas to drive same speed? its harder to pedal a bicycle gear

If the most difficult to turn the wheel it wouldent take more gas? On a bike higher gear (smaller rear sprockets) takes more effort to pedal.

Ah ... Box gasoline consumption does not equal. Charge is equal to the consumption of gasoline. If you're really great gears (ie, small rear sprocket), your fuel economy suffer in stop and go traffic because you will need a greater load on the engine to get the bike moving. However, these same reports that more will your engine to operate at a lower level when the speed dependent. Whether you use more gas or less gas at high speeds is entirely dependent on the amount of stop and go vs. regular road driving you do.

It will depend on the bike and also how small a gear you mentioned.
One thing certain is that the acceleration performance is reduced.
At highway speeds, if the bike has the power to maintain some speed, engine speed will be lower so there will be a slight reduction in fuel consumption. If the bike can not sustain that speed you're going to have to retreat, which takes you back to somewhere near the original ratio of overall transmission. The general rule is that the rider + bike needs some power to travel at the speed of the engine and some require a certain power to turn some RPM. If you can reduce the speed without loss of speed, you win.

The bicycle must have sufficient power to muscle speed and once at speed it would take less engine power to keep the tire rolling. Some stunters do to give the bike more torque to the rear wheel to make it easier to get the front tire on the ground. Good luck and ride safely.
