Review on Stainless Raspberry Chassis Platform by KOOKYE by Brandon Plowden

Anyone who designed street bikes has to either go back to school or find another job. They contain metal roller bearings, but the wheel is then secured to the chassis with a plastic shaft, and if overtightened, the shaft will bulge out, forcing the shaft into contact with the wheel. It's easy to tighten (it's plastic), but You must tighten it well or it will turn off. If the plastic shaft is sticking out, the wheel won't spin for some reason!
