Bit late to the party, but I've been charging about on a Mango bike for six months, and love it. It's a decent enough no frills entry level bike, and priced accordingly. I changed the wheel nuts front and rear as they round out pretty easily and put spd's on, but otherwise it's as supplied and will be carrying me on the Dunwich Dynamo and a few of the shorter Audaxes/Sportives this year. Each to their own of course, but I'm a happy chappy with mine.
