mountain trike

I'm selling my Trek 4500 mountain bike (14" frame) as I've hardly used it in recent years. It has Rockshox front suspension, Deore rear deraileur and Alivio front deraileur. It is in very good condition, low mileage and has always been stored under cover. Photos can be found here...

Shopping in Tesco's at the weekend I noticed a guy wheeling around on one of these: A seriously heavy-duty looking bit of kit, and not something I'd seen before, so I stopped and asked him about it. He was very friendly and explained it was a Mountain Trike...
