one could, but we don't drop anybody so you'd actually have to pedal your bike backwards. I'll allow half an hour for Tesco, which gives an average of a tad over 10mph - perhaps as much as 11mph. That sounds like not very much, but we have to get out of London, go up Bury Hill and take in some sights - and that's before we get to punctures.Sounds lovely... but for the word SUPERSPEEDY. Not really sure what this means on the ground compared with normal. Guess one could just come along and try not to get dropped eh?
