Bicycle 20, 24 and 26 inches refer to the diameter of bicycle wheels in inches. Converted, they are 50.8cm, 60.96cm and 66.04cm respectively.
If you are 1.65 meters tall, you can consider buying 24-inch or 26-inch tires. If you are a novice and afraid of being too high, you can try 24-inch tires.
But the choice of tire diameter has nothing to do with the height factor, because the seat can be adjusted. If you are too afraid to step on it, you can lower the seat. The adjustment range of ordinary bicycles is about 15cm.
The part that has a lot to do with height should be the border part. The following is the appropriate height corresponding to the frame size:
14 inch-150- 160, 15 inch-155- 165.
16 inch-160- 170, 17 inch-165- 175.
18 inch-170- 180, 19 inch-175- 185.
20 inch-180- 190, 2 1 inch-185- 195.
Vehicle condition inspection
Normal riding does not require any technology, but it is the most important and basic item in bicycle maintenance. It is very important to check the condition of the bicycle before riding, and it is often forgotten. Therefore, before riding, remember to do the following checks:
Check the size of riding posture: if you are not riding your own car, remember to adjust the seat cushion to the appropriate height before riding.
Check the tightness of screws in each part: check whether the front and rear wheels are quick-released and the seat cushion lever is locked, check whether the handlebar is fixed and whether other screws are loose.
Check the tire: Check whether the tire pressure is sufficient. If not, pump it up to a suitable pressure, check whether there are cracks in the tire wall, whether the cut tire tread is too shallow, and replace the outer tire if necessary.
Check the brakes: try to pull the front and rear brakes and check whether the brakes can stop.
Check the front wrist: step on the front brake and shake your body back and forth. If there is a shaking gap, it means that the front wrist needs to be readjusted.
Check the transmission: after starting, try to change the front transmission and the rear transmission respectively, whether it can smoothly change to various speeds and whether there will be abnormal noise.
