Its a
Tern Verge D9. For a folder, it's a not bad 13kgs with the mudguards and kick stand. So not too bad. It's a fair old nippy bugger which gets up to speed quick. The gears though are a little bit low for me. It's easy to ride through traffic but I cut off an inch each side of the handlebars and may even take off another inch making it much easier to filter. No effect on the handling. Great hydraulic disc brakes too.
Current model, Verge D9 is £1150 direct but no doubt can be picked up cheaper. There's one on the bay for £399. Which if has been looked after (it looks like it has been) is a bargain. Its a pretty much bombproof bike.
