SUVs ― mountain, fatbike, two-suspension;
sports ― road, track, cyclocross, cutting, for freestyle and trial;
for asphalt driving ― urban, hybrid, touring, folding.
According to the classification, the models are divided into women’s and children’s, trucks and trailers, tandems, unicycles, choppers and cruisers, electric bicycles.
Each of these types assumes design features corresponding to the functional purpose of the model. For example:
the tandem seat is designed for two people;
cruisers for long walks are equipped with a wide comfortable saddle;
mountain SUVs have a massive frame and wide tires with toothy treads;
the designs of women’s and children’s bicycles take into account the physiological characteristics of riders.
Proper gear shifting makes it easier and more comfortable to ride with less effort, and will also increase the service life of all elements of the bicycle transmission. We have prepared several rules and recommendations on how to switch speeds correctly on a bicycle:
– You can switch speeds only in motion, that is, while pedaling.
– For correct and smooth shifting when shifting gears, it is necessary to loosen the load on the pedals.
– Switching speeds should occur sequentially, there is no need to jump through several speeds at once.
– When climbing uphill, it is not necessary to throw a chain between the front stars, and between the rear stars is quite acceptable. If there is a hill ahead, it is better to switch the speed before you enter it.
– If extraneous sounds are heard after switching speeds, then the switching has not occurred and it is necessary to put the squeeze on the shifter lever.
The essence of switching speeds is in dragging the chain from one star to another. And various combinations of front and rear stars allow you to adjust the load of the cyclist. But first let’s turn to the transmission device of the bicycle.
The transmission is all the parts and components of a bicycle that provide energy transfer to the rotational movement of the rear wheel. The transmission consists of a carriage, a system of connecting rods, a chain, sprockets or a cassette (or ratchet), front and rear speed switches, as well as shifters (they are also sometimes referred to as manettes).
Switching speeds occurs through shifters, which are located on the steering wheel. With the shifter of the rear derailleur located on the steering wheel on the right, the chain is thrown between the rear stars, and with the help of the shifter of the front derailleur (it is on the left on the steering wheel) – between the front stars.
Most multi-speed bikes have three driving stars and six to eight driven stars. The front stars are counted from small to large, and the rear ones, on the contrary, from large to small.
