What are the current free bicycles and electric tyres? What's the price like? If you have a web site, you can send it to me and add it in detail.
There are 4 kinds of bicycle tyres1. pneumatic tires2. solid tires3. polyurethane tire4. pneumatic free hollow tire
3. when the temperature is poor, the tires become soft, the supporting force and elasticity decrease, and they are easy to come out. At low temperature, the tires become hard4 very good, high temperature 70 degrees to 70 degrees below zero, can be used normallyWear resistance1 General2 poor3 general4, very good, continuous operation of 3000 kilometers, generally no obvious wear, good wear resistanceAging resistance1 generally long-term use of the tire surface, easy to crack2 general3 difference, long-term use of tire harden, until the loss of elasticity, easy to be piercing sharp objects
From elastic comparison1, very good use of compressed air to produce elasticity, excellent elasticity2 difference3 general4, good rebound rate, good rebound performanceWeather resistance1 generally easy to burst at high temperatures, low temperature, air pressure is less likely2 generally, at low temperatures, tires become stiffer and less resilient
