I bought a bike from Chris (don't know his username on this), and rode back from Deptford to Bayswater, where I'm stationed, taking delightful wrongturns the whole way through. Gee, isn't London Bridge etc. fun?! It wasn't half as bad as I thought it would be, it was okay, even if there were a few teething problems (down to me more than the great bike Chris sold me). First ride was about 19.47 km (according to Endomondo) or 12 miles, ish, in about an hour and 20. Not bad for getting lost, dealing with London traffic, etc, etc. All I'll say, is god bless Google Maps (I stopped to use it, didn't use it while cycling. Did see one birk on a Boris bike texting and cycling down a main road).
