Retrospec Mantra Fixed Gear/Single Speed Bike - SOLD BOXED (NOT BUILT)
The Mantra is our new and improved fixed-gear bike model. It is fully equipped to handle your city commute every day of the week. The hand-built, tig-welded steel frame has weatherproof sealed bearing hubs, all prerequisites for city riding. The sealed bearing hubs keep out dirt and moisture and thus require less maintenance over the lifetime of your bicycle. The frame and fork have bar spin clearance, horizontal dropouts, and no toe overlap.
This fixie comes standard with a flip-flop hub, which allows you to take back the control of your ride. Embrace your inner urban cyclists and choose how you cycle. With a simple flipping of the rear wheel, you can ride fixed-gear or single-speed with a freewheel. Riding a fixie is your choice to make.

General information about our shipping
I love this bike! It's amazing value for such a beautiful well built bike. The frame is lightweight for the material and price point; the welding and paint work is perfect. The option to ride single speed or fixie is great, and when riding single speed you've got both front and rear brakes included when it arrives so you immediately feel safe on the road. Little things really pleased me, such as the velcro straps for the pedals, which look the business and are also really effective on the flat pedals. I was annoyed I didn't have any tools with me when the bike arrived - but I didn't need to worry as everything was included in the box and I was out on the road in half an hour. I can't believe you can get such good quality for this kind of money.
