summary for those of us without youtube access?
Chap riding a bike down a big Russian street (kind of like Oxford Street?).
The bike he’s on can transform from being a chopper (long forks stretched out in front, saddle over towrads rear wheel, long chainstay horizontal to ground) to being a clownbike (bb way up high, long forks near vertical, long chainstay near vertical).
Basically, the rear wheel folds under the bike, lifting the saddle and the long front forks become tall front forks. All this done by a hydraulic ram looking thing that extends from the top of the seattube down the (very long!) chainstay.
