I'm officially in love with my Mango fixed gear/single speed bike. I upgraded to the fancy 6-spoke wheels which are super strong and pleasantly comfortable (they've also had plenty of admirers!). Not the lightest bike, but I wanted something practical for the winter months that will also build my strength more than a geared bike. This bike feels like it can take whatever nature throws at it (still need to maintain it though!) I would have given five stars, but there was no reply to my emails and no updates on how long it would take to build and be delivered (mine took about two weeks, which is excellent). Hopefully, Mango can sort this out but that's the only criticism I have… and I'm already thinking about getting another one!
