Hi Tibo, not much to update on yet.
Between the rain and my weird landlady (how the hell does she do it? she vanishes without notice for 4 days to Morroco or maybe just down the street and then turns up at at 12:15am within 2 minutes of ... well, it's not an appropriate subject for this forum) all I've done so far is collect the bike, give it a test ride and buy a saddle. It's bigger than I expected, just about my size but I have to drop forward over the frame when I come to a stop instead of just putting my foot down - I think that's common with cruisers.

It seems cheaply made, the struts holding the mudguards are tin and the chainguard is much the same - the one on my old Raleigh Chiltern is more solid. The bearings on the forks (or headset or whatever it's called) are probably cheap, they're some far-east asian/china make. But the frame, forks and wheels seem okay and there's not much to go wrong with a single gear bike. The seller had to fix the hub brake (he paid for it - £35) but I don't know if that was normal wear and tear or because it was a bad bike.
I'm not too happy trying to ride uphill, OMG it's hard work without low gearing! But I suppose that's par for the course with single speed cruisers.
I don't think the bike is good enough to spend much money on (the saddle I can swap to another bike later) but it does look good, in fact it looks very good so overall it was worth buying.
