The elastic bicycle allows the user to press a button that winds up stong elastic so that when the user presses another button it releases the elastic and moves the bicycle quickly forwards... This allows the user to quickly get away when traffic lights turn green!

       What powers the winding?
—pocmloc, Mar 24 2011
   

       The button powers it, of course. Like the light switch powers the light.

       Perhaps a small internal combustion engine ?

       Why never external combutions?
—rcarty, Mar 24 2011
   

       Actually forget the buttons! there should be a wind up handle that is used to wind up the elastic.
—AndyH, Mar 24 2011
   

       (+) I would suggest using braking resistance to wind the elastic. The button would just release the stored energy allowing you to use it on an uphill slope or anywhere else.   

       what [fries] said. (+)

       // external combutions //   

       Because combuting is now illegal in many jurisdictions, the special breed of orchid required is increasingly rare, swans are a protected species, and it's impossible to get the stains out.

       //forget the buttons!//   

       Perhaps the button could power the wind up handle.

       oooh I know ... why not make this a hybrid. When you use your brake, elastic gets wound up (and slows you down). When you press this magic button, the elastic force is released .... [+] ... I want one, please!

       They did this on Scrapheap Challenge a few years back. One bike had a large flywheel, the other had a load of bungee elastic on a winch. The flywheel one was infinitely better. (Apart from perhaps cornering, but this was a drag race.)

       In East Fenglia, cyclists circumvent this thinking by just not stopping at lights. That's a Cambridge education for you.

       I had to pay a fine for failure to stop last year, and now I learn I should have actually recieved a degree from Cambridge.

       Where they may or may not have touched on the whole " i before e " issue.   

       I've been racking my brains and the halfbakery search field for a bicycle idea I could swear I saw here previously, but I'm unable to locate it.   

       I'm going to post it and find out what happens.
—normzone, Mar 24 2011
   

       Read your post, and I linked to the archived idea in question.
—rcarty, Mar 24 2011
   

       There should be a distinct spelling to differentiate "Read" from "Read".
—MaxwellBuchanan, Mar 24 2011
   

       There is. If you can't see it, you've probably got a browser problem. Lipid's nice, but it chokes on extended-unicode.
