Kommon Aluminum-Magnesium Alloy Compact Foldable Electric Bike

Sale price $899.70 Regular price $1,499.00

High-performance Frame
Aluminum-magnesium alloy frame with high rigidity and good shock-absorbing.

One-piece Mold Technology
The utility model is characterized that the front fork tube is integrally formed with the cross beam, the standing fork is integrally formed with the flat fork. The post tube, flat fork, and the seat tube are each connected. The firmware is connected together in order to solve the problem of low strength of the welded frame and cracks in the welded area, it can help improve the rigidity of the frame folding bicycle locking device.

The connecting rods 1 and 2 are tightly connected by the use of a rotatable eccentric shaft to move the tension bar. The purpose is to prevent from loosening of the locking device, an L-shaped rotating member is used to lock the tumbler.

This folding lock solves the problem of failure or even loosening of conventional locks due to wear. Its life time is even longer than that of a bicycle. The tightening force required during operation is small, and the folding position can be firmly locked without any effort, greatly improving safety performance.
