Comparison of trifold folding bike of 20inch and 16inch.

In this report, I compare and contrast a 20 inch and a 16 inch 3 trifold folding mini-velo. In Asia, where patent-expired Brompton clone bicycles are very popular, it is possible to build a trifold folding bicycle with the same design as a Brompton by selecting the frame and basic parts, as well as various parts with specifications that are not available in the factory version, to complete a bike to your desired specifications. In addition, because Shimano parts can be used for the external transmission and sprockets, we obtained 20 inch and 16 inch models of the compactly foldable chromoly-framed Brompton Clone mini-velo bicycles and actually took them on a loop trip from Singapore to Japan. The 20 inch bike has 20 inch aluminum wheels, 10 speed Shimano external Tiagra wheels, and a chromoly frame with the same three-stage folding design as the Brompton. The 16 inch bike has 16 inch aluminum wheels, a Chinese 9-speed external derailer, a chromoly frame, and the same trifold folding design as the same as Brompton. Comparing the two bikes, I realized that the 20 inch and 16 inch bikes have different characteristics due to the difference in wheel size and wheel base length. The 20 inch wheel is more stable, easier to maintain cruising speed, and less tiring to ride for a long distance, with the 20 inch wheels, it is easy to maintain about 25 km/h in cruising. On the other hand, the 16 inch wheels are slightly more compact when folded than the 20 inch wheels, making them suitable for carrying transport with wheeled bag. They are suitable for leisurely pottering at speeds of 25 km/h or less. Both the 20 inch and 16 inch models have a highly rigid frame that does not flex or squeak, and they are folding bicycles that move forward when you step on them. Both are easy to ride, with a good match between the front chainring and rear sprocket, but depending on the application, the rear sprocket can easily be replaced to customize the gear ratio. These clone models can be replaced with pedals, tires, and other components for a better ride feeling. Since they are so well made, we have decided to assemble, sell, and ship them to Japan from May onward for foreign cyclists who want to use these bikes in Japan. #Folding #Chromoly frame #Maintenance #Trifold #Brompton #Brompton clone #20inch minivelo #16inch minivelo
