Some guys at my high school made one and bought it out each fundraiser, pay $1 and try ride it 10 metres, win $100. No one ever did it in my 5 years there.

seen these before the handlebars are reversed! lol

Did this at university many years back. It doesn't need geared reversed steering to make a virtually URB (unridable bicycle). Tampering with front-end geometry will do.
haha, as a kid I crushed unto a parked car trying to ride my bike with my arms crossed.

It can be done. It is just most cyclists don't understand the engineering dynamics involved.
The rules of a bicycle are. 1. You balance the bike with the steering. 2. Steer the bicycle with your weight.
Explanation. 1. As you are riding along and you start falling to the left, you steer to the left. This puts the tyre/road contact point under your centre of gravity and you stop falling. Fall to the right, turn right.
2. To steer the bike you lean in the direction you want to turn and then use the steering to balance the bike at rate of turn you want.
To ride the URB you need to focus but just think "fall left turn right" "Fall right turn left". You steer as normal by leaning the way you want to turn.

Yeah interesting.

Otherwise known as countersteering.

Brilliant ideas and video. I would've like to see him ride the URB just after the normal bike to show he could do both - if he could do both!

My understanding of counter steering is to quickly initiate a fall to one direction to initiate a turn rather than balance the bike.

Note that riding a tricycle is completely different. You balance the trike with your weight and turn the trike with the handbars. Adult tricycles (and motorcycles) are tricky for the uninitiated who think they will be a piece of cake.

There's a really easy trick to riding a bike like that. Cross your arms. Right hand on left grip and left hand on right grip.
Nothing complicated about it at all.

No 2 is not quite correct. You initially steer in the opposite direction you wish to turn and then as the bike and rider falls over you then "countersteer" in the direction you wish to turn. (See # 10, Trog's on the nail).

oddly enough the video showed people doing that and still unable to do so!

The guys at The Gypsy Fair used to have one for people to try out, funny as to watch. I think there was a prize if you managed it.

People who say it is easy have no idea. If you wanted to countersteer this you could first have to countersteer the countersteer. Also science does NOT know yet how exactly we are able to ride a bike, there are formulas, but they only ever work in some situations, so it is still a mystery.

that's why sidecars are such weird creatures to ride/drive.
My interpretation of the terminology is "countersteer" is to turn in the opposite direction to desired turn and "steer" to turn in the desired direction.
