After lurking on this forum for a while, and armed with a list of options and accessories taken from all of the advice here, I turned up at a local folding bike retailer yesterday. I explained my intended usage - a couple of times a week 8.5 mile ride on roads and cyclepaths to a rural station with a couple of light gradients and then a short blast from train to office at the other end.
When I said '8 and a bit miles', the assistant sucked in air through his teeth and gave me the definite impression that a Brommie was not suitable for me. Undaunted though, I took an M6 out for a couple of spins, and could see what he meant - it didn't really have a top gear for the cruise out to the station, but it did seem to have plenty of low ones for the crawl back up the hill to my house in Stroud.
So, what do I do? He obviously had no interest in turning me off the idea, but was he right? Should I get a cheapo road bike and lock it up at the station? Would the higher gearing mod be appropriate? Or should my heart overrule my head an just say 'Dammit, I want one of those sexy little things and I'm going to have one regardless'?
I also had a look at all of the other folders (even an A-bike), and wasn't as attracted to any of the others. It was such a disappointment, and the Cyclescheme ends on Monday....
