Health hack - ride around town on the cheapest possible bike

My brand new commuter bike! Last night, after two years use and while giving Helen a backy thru Soho to the theatre my last one finally collapsed under the weight, literally! After salvaging the lock and saddle it's onto a new one. I like a challenge! You will never get fit commuting on a road bike in Lycra - Try one of these. A zone 1-2 tube pass costs £125 per month. This bike will pay for itself after 15 days use - the last one cost me £1 a week! that's mad.

PS Love that on its own site the bike can still only muster 3.4/5 - this is going to be like breaking in a wild horse.
