Cycling doesn't take only 3 or 5 minutes, even using it as a transport, comfort for riding is still important, therefore, choosing a suitable cycle for yourself is essential. A good cycle is basically comfortable and is able to transfer your body energy to motive power. A good cycle doesn't require high prices. Therefore, before purchasing, one should study what is suitable.
Selecting the frame
Most of the sizes of the mountain bikes in Taiwan are 14, 16, 17, and 18 inches. The touring bikes can be divided into 16 sizes by the length of seat stay, from 47 to 62cm (one size with one centimeter different). To calculate it, time the distance from the crotch to the ground by 0.65.
Mountain Bikes
Size | Suitable Height |
---|---|
14 | under 155cm |
16 | 155cm~170cm |
18 | over 170cm |
20 | over 180cm |
Touring Bikes
Valid length of seat stay | Suitable Height |
---|---|
50 | under 163cm |
51 | 163cm~168cm |
52 | 168cm~173cm |
54 | 173cm~177cm |
55 | 178cm~181cm |
56 | 181cm~185cm |
58 | over 185cm |
It is recommended that: nearest size > smaller size > larger size. Choosing the wrong size is not going to ruin your life, but it will give you sore muscles. Therefore, pay attention when you choose so you won't regret on your purchase.
Materials of the Frame
The frame is the soul of a cycle. A good frame should have light weight, strong solid, and high rigidity.
Aluminium Alloy
Aluminium alloy fram provides lightweight, sensitivity, and high rigidity. However it also transfers every vibration from the ground the the comfort is slightly reduced.
Carbon Fiber
The carbon fiber frame provides elasticity, riding stability, continuity for long-distanced travailing, and great comfort.
Titanium Alloy
The characteristics of the titanium alloy is similar to the combination of aluminum alloy and carbon fiber. It provides the elasticity of carbon fiber and the lightweight and rigidity of aluminum alloy. However, there benefits require higher prices than other materials.
Alloy Steel
Steel is the traditional material for cycle frames. The modern alloy steel provides great results on rigidity, elasticity, transmission, and stability. However, the only disadvantage is that steel is heavier than other materials.
