    To set a land speed record with the bike they now need to find £7,500 for admin costs. That's rather a lot really! But then so is the approx 1,000 man hours put in to reach this stage.

    That is so strange looking. I would be afraid of it breaking. Are there weight limits, meaning could my 300lb neighbor ride one you think?

    There are limits to riders on most bikes. If you look into suspension units on bikes, they normally cover riders 12.5-13.5 stones (14lbs per stone) then you have to use greater 'weight' springs in them (or pump more air in) and the limit is approximately to cover a 15.5 stone rider. (medium - firm - extra firm)

    Tires alone are rated to carry a certain amount of weight. If you look at the side of a tire you'll see the max psi rating for inflation, and know that the heavier a rider, the higher the psi you need to pump in to carry that rider and have the tire work the same. Obviously if you are so heavy that you need more psi than the tire is rated for then you begin to see the problem.

    Wow. You bring up points I had not thought of. Like in horse racing, the weight of the rider can make all the difference.

    A 500 lb man really couldn't ride a bike unless it was specially made.

    Cool, thanks!

    as a very keen rider and non car owner, this can only be a good thing for us all and incurige more people to cycle

    I would love to live in a town where I could ride a bike everywhere but where I live I am not afforded that luxury.

    no, not a luxury if it's an hour bike ride! I was picturing Jessica Fletcher's character in Murder She Wrote =)
