Push bike (http://www.youtube.com/watch?v=mYIKfEU8yl8) - ridden by helmet wearer

Out and about (http://www.youtube.com/watch?v=UbJ1sseQVbY) around town.

the helmet holds the anti-gravity mechanism. A backwards wheelie on the front wheel?? a vertical hop up eight steps, then a spinning hop up eight steps?

out of this world

That insolent fellow is having too much fun.

Pretty cool.

It looks to me like:

1. In some tricks he does not use any sort of clips to attach his feet to the pedals, but in others it looks like they would "facilitate" the tricks (not that any of those tricks look easy).

2. In some tricks, the rear wheel is not fixed, but in others it must be fixed because he is still able to pedal backwards. Different bikes for different tricks.

Today, I rode my bike to work. In the rain. I arrived in one piece and dry (Thank you, Gore Tex!). That's a good enough trick for me.:p

Took a look at them again. The rear wheel is obviously not fixed, and his feet are not clipped in. He is just gripping the pedals with his toes, somehow, so he can lift the back wheel.

I'm puzzled by this - I suspect either a clutch or some tricky mechanism which gives a "slippy" drive in reverse - anyone know the real answer?

check out the e-vent jackets,,better than Goretex for breathability.

Thanks, Lee. I just use the same general purpose rain gear I use for canoeing, camping, and walking the dogs.

That might account for it, or he may just have a different rear wheel to swap in and out, depending on his mood.

That, and years and years and years of practice.

Loved the running repairs in this one.

double sided hub, freewheel on one side, fixed on the other, flip the wheel over, but I think he's simply letting the freewheel rotate the pedals backwards as he's coasting backwards downhill(it's hard to see on the picture but it's downhill) with the front wheel in the air. It's like a magic trick in that the mind is making a connection that isn't there. The backwards turning freewheel will drive the pedals, it's going forward that it doesn't. He's controlling the backwards roll with resistance,not driving it.

You can see when he's done with the trick and coasting forward the pedals aren't moving and the bike is moving forward,,ie. it's got a freewheel cog on there.
