They're not light, but at least they're tough as old boots...

We've all seen BMXers leaping about in amazing ways on their purpose-built 20-inch-wheeled bikes, but how would they go on something rather heavier and more ponderous? Pretty damn well if this video of Tyrone Williams on a New York Citibike is anything to go by.

Citi Bike's are New York's equivalent of London's Boris Bikes. Launched in May, it was greeted with general approval ands, this being the US, a lawsuit about property values. Wall Street Journal editorial board member Dorothy Rabinowitz called the programme  'dreadful' and accused Mayor Michael Bloomberg of running a 'totalitarian' city government that was 'begriming' the city's best neighbourhoods, as well as trotting out just about every other anti-bike cliché in history.


Our official grumpy Northerner, John has been riding bikes for over 30 years since discovering as an uncoordinated teen that a sport could be fun if it didn't require you to catch a ball or get in the way of a hulking prop forward.

Road touring was followed by mountain biking and a career racing in the mud that was as brief as it was unsuccessful.

Somewhere along the line came the discovery that he could string a few words together, followed by the even more remarkable discovery that people were mug enough to pay for this rather than expecting him to do an honest day's work. He's pretty certain he's worked for even more bike publications than Mat Brett.

The inevitable 30-something MAMIL transition saw him shift to skinny tyres and these days he lives in Cambridge where the lack of hills is more than made up for by the headwinds.
