Front wheel drive bikes offer better traction and stability, especially in wet or slippery conditions. They also provide a more efficient power transfer from the pedals to the wheels, making them easier to ride uphill. Additionally, front wheel drive bikes tend to be lighter and more maneuverable than rear wheel drive bikes.
With a chain drive the driven wheel will always rotate in the same direction as the drive wheel, but in a gear drive the direction of rotation will change between drive wheel and driven wheel.
Motor bikes work by using a small motor and chain to drive the rear wheel. This allows for a light weight, yet powerful mode of transportation.
A gear drive uses gears to drive the camshaft vs a belt or timing chain. Some bikes use a shaft drive vs a chain that is often confused with a gear dive.
Not all bikes have "gear". Straddle bikes and direct drive bikes - with cranks directly attached to a wheel axle - don't have gears.
"Belt drive" refers to the type of final drive from the gearbox to the rear wheel. Traditionally, bikes have a chain & sprockets. More recently, some manufacturers have replaced the chain with a belt on some models. The belt works in exactly the same way as the chain, and some say that belts are harder wearing than chains. (They are certainly less likely to develope tight-spots).
Because if you have the pedals stuck to the wheel axle, and no gearing inbetween, the only way to get some useful speed out of the bike is to have a really large wheel.Because before the chain drive and gearing was invented, bikes were direct drive - meaning that the drive wheel spun at the same rate as the pedals. The only way to get some speed out of the bike then was to make the drive wheel really big.Once the chain drive made it easy to add a gearing ratio wheels could be built with equally sized wheels and a better rider position.
Gates Carbon Drive bikes offer advantages over traditional chain-driven bikes in terms of durability, cleanliness, and low maintenance. The carbon belt drive system requires less maintenance, lasts longer, and does not require lubrication like traditional chains. This results in a cleaner and quieter riding experience with less hassle and upkeep.
Because before the invention of the chain drive, the driven wheel would only turn as fast as the pedals turned. and the only way to get some decent speed was then to make the drive wheel as big as possible
A 2003 sportster has a chain drive for the promary, firm the engine to the transmission, and a belt drive final drive. The final drive is from the transmission to the rear wheel.
Some innovative alternatives to traditional chain-driven bicycles include electric bikes, belt-driven bikes, shaft-driven bikes, and friction drive bikes. These alternatives offer different benefits such as reduced maintenance, smoother rides, and increased efficiency.
the chain in the transfer case will only turn when engaged into 4 high or 4 low. the chain is only there to operate the front wheels. with a busted chain all you will have is two wheel drive but you have the ability to use the low range as normal, you not have 4 wheel drive. i have modified transfer cases to do do just that and installed them in what i call "ghetto sleds".
