11.Installation Method
Find the properposition on the bicycle handerbar ,fix the bike bell on the handle with the silicone strap. Choose the proper distance then fix the controller on the handle .
Inflate to the right amount. The deflated tire caused by insufficient inflation of the inner tube not only increases the resistance and makes cycling laborious, but also increases the friction area between the tire and the ground, causing the tire to accelerate wear and tear. Excessive inflation, coupled with the expansion of the air in the tire in the sun, will easily break the tire cord, which will shorten the service life. Therefore, the amount of air should be moderate, enough in cold weather and less in summer; less air in the front wheel and more air in the rear wheel.
Don’t overload. The side of each tire is marked with its maximum carrying capacity. For example, the maximum load capacity of ordinary tires is 100 kg, and the maximum load capacity of weighted tires is 150 kg. The weight of the folding bicycle and the weight of the car itself is divided by the front and rear tires. The front wheel bears 1/3 of the total weight and the rear wheel is 2/3. The load on the rear hanger is almost all pressed on the rear tire, and the overload is too heavy, which increases the friction between the tire and the ground, especially since the rubber thickness of the sidewall is much thinner than that of the tire crown (pattern), it is easy to become thinner under heavy load. A rip appeared and burst at the shoulder of the tire.
(4) Sliding treatment method of folding bicycle chain:
If the bicycle chain is used for a long time, the sliding teeth will appear. [Mountain Bike Special Issue] The daily maintenance and maintenance of the bicycle freewheel is caused by the wear of one end of the chain hole. If the following methods are used, the problem of sliding teeth can be solved.
Since the chain hole is subject to friction in four directions, as long as the joint is opened, the inner ring of the chain is turned into an outer ring, and the damaged side is not in direct contact with the large and small gears, so it will no longer slip.
