That is the rear disk wheel of a track bike, painted in the WWII era bomber style.
A full shot of the bomber bike, painted to look like the old school bomber, with some weathering and combat damage.
The most sporty exercise bike on the planet!
Ok, we actually have bikes made of bamboo, but here is a bike painted to look, very realistically, like bamboo. Amazing work here.
Note how the original frame has been customized and the stock decals are used as background for the new icicle treatment.
