Gear ratio effect on stopping/skidding

Yeah, I can definitely get on board with that!

Nice video, not much progression there really though - just imitating bmx in a really clunky ugly way (apart from all the whirly flatland stuff). There is a reason that dirt jump bikes and bmx's have tiny frames and super low saddles - having a big gate of a frame and a saddle right up your arse makes it next to impossible to hop properly or tweak in the air. Riding larger wheels and a bike with a longer wheel base means that transitions are nothing like as smooth and you have much less control as it's harder to shift your weight forwards/backwards. Just means that riding isn't as fluid.

I just see it as shooting yourself in the foot if you know what I mean - I can totally see the benefit of riding fixed in terms of what you were talking about generating pop and riding fakie - but thats a drivetrain issue, I'm really talking about the build of a bike and it's shape.

I'm all for people doing whatever they want on bikes however they want.. I just think it's a bit stupid to not pick the right tools for the job. I kind of just see it as a fashion thing.

Not really an issue, its fixed vs freewheel, you can do it on fixed and you can't on freewheel, with regards to the right tools for the job, most of those guys are on freestyle specific frame/fork bike setup's, which look nothing like traditional track bikes, they have more standover clearance, different geometry, and are heavily re-enforced and built with much tougher/bmx parts to take lots of abuse.
My bike is possibly one of the ugliest most unfashionable things you'll see on the roads, but its designed for a purpose, and it serves that well, some people ride bikes for fashion, some for fun, but I don't think you can deny that to reach a certain skill level, the level of practice required kinda goes beyond fashion.
Everyone has their own reasons, personally I couldn't care less how my bike looks, i'm gradually making it more and more bulletproof as the months go by, and its handling the abuse better and better as I upgrade parts, I ride my bike for fun no other reason, it makes me smile, and the good times I have with my mates just remind me of how fun it is, so I will continue to do so, as I have done for many years, until it either stops being fun, or I am no longer able to do so.
Oh and if you think its next to impossible to hop properly, clearly you haven't seen Tom and Ted ride, those guys can pop 2-3 ft+ hops on fixed easier than most peeps can on bmx, just because you can't do it...doesn't mean there aren't people out there that can :)
