How To Gears On A Bike Work

How bike gears actually work.

How to gears on a bike work. The lowest gear ratio on the bike might be a front chain wheel with 22 teeth and a rear gear having 30 teeth. Instead a gearbox is integrated directly into the frame with the weight. How do gears work. You can think of gears as the same thing as speeds a bike with 18 gears is an 18 speed bike.

A bike with 30 or more gears is not an indication of a machine designed to break the land speed record any more than a bike with only a single gear assuming similar ratios. The gear shifters are attached to the derailleurs by gear cables or electric wires in these new fangled electronic systems. The idea behind multiple gears on a bicycle whether it s an older 10 speed bike or a modern mountain bike with 24 gears is to let you change the distance that the bike moves forward with each pedal stroke for example a normal bicycle has wheels that are 26 inches in diameter. Play around with the gears.

Part of the problem of a hub gear is that it adds weight at one end of the bike which can lead to unbalanced handling. First let s get our terms straight so we re on the same page. And when a bike has multiple gears two or three chain rings up next to your pedals and up to 11 cogs on your back wheel it makes. Consult your bike shop at the time of purchase on how yours work or simply jump on your bike make sure to pedal and push your shifters to get a sense of how they function.

In the mechanical sense derailleur gears work by the rider pulling or pushing the gear shifter which shortens or lengthens the relevant gear cable. Instead of touching directly and rotating in opposite directions each pair of gear wheels is connected by a flexible metal chain kept taught by a springy lever and gear shifting mechanism called a derailleur so they turn in the same. Cycling gearing can be confusing. This video simplifies all the terms and explains how your gears impact your riding.
