The Diamond backs are the previous years KHE bikes as Kuwa says.
A few issues with them, but the main one being the geometry - they are like scooters. Far too low standover and far too steep front end - great for ramp rats, but not for the older rider.
Also those bushing BB's are chronically bad, always too stiff and wear really quickly so the crank is forever wobbly. We see them often on the KHE's in here, and because there isn't a ridge inside the BB you cannot replace them with a standard bearing. But KHE are now producing a replacement bearing set for them consisting of a cup (like on a US BB) and a set of small bearings (which in turn brings strength problems)...but does highlight that there is an issue with the bushing type.
Agreed, some of the parts are good on it, but all that glitters is not gold.
