Find your inner peace with Retrospec’s Mantra. Ride happy.

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.

Flip-Flop Hub

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.


We handpick every component that goes on our bikes. From the tires to the saddle, we select the crème de la crème. Our bikes sport Kenda Kwest commuter tires for minimal resistance, double-wall super deep-V Star rims, and always reliable KMC Chains. Included with this fixed-gear bicycle are removable fixed-gear freestyle Velcro straps and integrated seat post.

We strongly suggest that you take your bike to a professional bicycle mechanic to be built and/or checked out to ensure that the cog and lockring are tightened, the brakes adjusted, and the wheels trued.
