I found this mini velo bike on a Japanese page. This has got be the nuttiest thing ever, just crazy amounts of carbon. The first time you see a photo of this bike, you might be tempted to assume that the frame was adapted from a BMX bike or something because of the really tall steerer. However, I have seen several different designs all with this set-up, and the details of the frame suggest that the bike was intended solely for this application.
If you pan down their page, you see some other inexplicably bling equipment, like 20” carbon clincher rims and 3-spoke aero wheels.
