I posted an earlier deal for these but it got largely overlooked. It's not cheap but it is a fantastic deal and I couldn't get near it anywhere else. Was worth my while driving 100+ miles to collect in Swansea but they will post. I'd like to think another HUKD member might benefit before they've all gone.
If you know anything about folders you'll know Dahon (US brand) is the biggest and most respected in the business.This model has a RRP of around £600 and most places sell them for £400 and up. This dealer bought a job lot of the 2009 model and is selling the remainder at two for £600 (or £350 for one).
Alloy frame (under 12kg) and 7 speed Shimano hub gears (no troublesome deraillers) did it for me. Not quite as compact as a Brompton if you want to take it on public transport every day but much more rideable with 20" wheels and great for putting in the back of the car.
There are cheaper Dahon models (and much more expensive ones) but I reckon at this price this is the best value out there.
No dealer site but this is their phone number: 01792 464640.
