The comfort and stability of Electric Tricycle are particularly important

Don't blindly think that the thick pipe of the brand Tricycle Motorcycle frame is good. The key to the quality of the frame is the thickness and material of the pipe. The pipes used in a good frame are generally of moderate thickness, but the thickness will be much thicker than the frame that looks thicker on the outside.

There are holes drilled at the bottom of a good frame, which is to facilitate the outflow of liquid during pickling and phosphating. The thickness of the pipe wall can also be seen through drilling. The inferior frame has not been pickled and phosphated, and has no holes, so it is easy to rust, and the ports are deliberately closed so that people cannot see the thickness of the pipe wall.
The quality of the frame is related to the safety, stability and life of the vehicle. Inferior frames are easy to break and cause safety accidents. So be careful.
Front fork sleeve shock absorption: You can judge the pros and cons by the appearance. The shock absorption of the high-quality front fork sleeve is hydraulic shock absorption, the inner tube is multi-level chrome-plated, and the surface is bright and smooth; the outer tube is finely polished aluminum tube. The mid-range front fork sleeve shock absorber is generally hydraulic shock absorber, but the chrome plating level is low, the appearance is poor, the color is dull and easy to rust, and the oil seal is easy to leak oil. Inferior quality is not worth mentioning, skipped here.
Rear leaf spring shock absorption: The number of leaf springs is five to six, and the width and thickness are moderate. The quality of shock absorption is particularly important for tricycle comfort and stability.
Details determine whether a product is a boutique, especially for Electric Tricycle with hundreds of parts. Screws use a lot of small parts, which can be distinguished from the color. The screws are silver and green, and the inferior ones are yellow and white. In addition, the front mud tiles, compartment locks, hinges, battery holders, pressure plates, seat plates, etc. must be carefully looked at.
Electric Tricycle are driven by electricity and have complex vehicle circuits. The wire harness core is thick and the layout design is reasonable. Inferior wire harness cores are hard and impure, easy to corrode and rust, insulating materials are prone to aging and cracking, and line failures are more likely to occur.
Before the battery is installed in the car, you can push the car back and forth. A good car is easy to push and has no noise, so that the car saves power during driving and prolongs the life of the motor battery. Inferior cars are heavy to push and accompanied by noise. When the car is running, it consumes electricity, and the motor is prone to heat, which shortens its life.
