Bicycle use low alloy steel pipe manufacturing

In order to reduce the pipe weight, increase strength, higher-end bikes with low alloy steel pipe manufacturing . In order to reduce the resistance of fast-moving , and some bike also features a streamlined steel . Spoke is generally equal diameter , in order to reduce the gravity , and made ​​both ends of a large middle small adjustable spokes , as well as to reduce the air resistance will be made ​​of flat spokes streamlined
1 , tire : soft edges of tires and tire two kinds of hard edges . Soft side tires wider cross-section , can all be wrapped around the tube , a relatively large area that can fit a variety of roads . Hard-edged tires , light weight, small size suitable for the ground Folding bicycle running on a flat road , with little resistance , the advantages of traveling light . The tread pattern is designed to increase the friction with the ground . Mountain bike tire width particularly wide , deep tread also accommodate off-road mountain with .
2 , the step parts : the left and right foot support member mounted on the axis of the crank member, the power level is converted to a rotational force of the apparatus , when riding a bicycle , the pedal force is transmitted to the first pedal member , and the pin pedal crank shaft , the central axis , the chain flywheel, rotate the rear wheel , so that the bicycle forward. Therefore, the structure and size of the pedal part is appropriate , will directly affect the rider's position is appropriate to put the foot , bicycle drive can proceed smoothly .
 Foot : can be divided into integral Cargo bike and modular foot pedal . No matter what style of foot pedal surface must have to be safe and reliable, has a non-slip performance , you can use a rubber , plastic or metal materials . Pedal must be flexible rotation .
3 , fork components:
Turn the handlebar and fork , you can change the direction of the front wheels , has played a guiding role of the bicycle. In addition, you can also play the role of controlling a bicycle traveling .
