This video illustrates a serious design flaw on the Wired Freedom e bike. It is a quality control issue that was obviously missed, but more importantly, the design of the linkage leaves much to be desired and should have been designed with more robust components. The bike flexes at the linkage points such that the bike feels as though it is made of rubber. The linkage arms are only 8 mm thick and can be seen to actually flex as well. They should be at least double the thickness for such a large bike. There are gaps between the linkage arms and the frame and bushings. The fasteners are as tight as can be, so there is no tightening the fasteners up to close those gaps.
The rubbery sensation can be felt during low-speed maneuvers, but not as noticeable unless one is aware of it. But the rubbery feel is felt very much more at higher speed maneuvers. Walking alongside the bike and taking both wheels over a standard height curb one after the other makes it really noticeable. The bike then feels like very chintzy and wobbles noticeably.
The rear end of the bike can be made to shake almost as though cracking a whip.
There is significant side to side movement that can easily be observed.
By holding the front brake lever on and pushing and pulling on the rear rack from side to side clearly shows significant lateral movement in the entire linkage from the rear shock absorber to the rear swing arm pivot point, and the linkage arms themselves do flex.
