Details

The Mantra is one of Retrospec’s most popular models for riders that want a great fixed-gear or single-speed bike. Riders love it because it’s durable, versatile, and affordable. Oh, and it looks darn good, too.

The Mantra is both a single-speed and a fixed-gear bike. It comes set up as a single speed, but thanks to the flip-flop rear hub it can be easily changed into a fixed-gear bike.

While Retrospec sells similar models, the Mantra is their premium version that goes above and beyond in order to provide you with a high-quality ride that you’ll soon be obsessed with. This bike is so fun and stylish that you’ll be itching to take it out for a spin as often as you can.

Take a look at some of the great features you’ll get with the Mantra.

With only 1 speed, the Mantra is virtually maintenance free. Just make sure your tires have air and you’re good to go!

The sealed cartridge bearing hubs will protect your bike against the elements and require less maintenance so your bike lives a long, happy life.

The dual braking system provides plenty of controlled stopping power when you need it for a safe, stress-free ride.

Fast-rolling, durable 700 x 28c tires give you plenty of traction without slowing you down so you’re able to dart around the city rain or shine.

For the serious commuters out there, the Mantra has mounts for a rear rack and two water bottle cages for extra storage capacity.

Navigating tight city spaces can be difficult with wider handlebars, so the Mantra comes stocked with a narrower 520mm bar that makes getting around in traffic (or in your apartment) much easier.

Whether this is your first single-speed / fixed-gear bike or you’re a seasoned rider who appreciates a great value, you’ll be impressed with the Mantra and it’ll become a fun part of your daily routine.

flip fop rear hub

The flip flop rear hub has a fixed gear cog on one side and a single speed cog on the freewheel side. This allows riders to easily change their bike from a single speed to a fixed gear bike and vice versa.

Retrospec mantra comes with rear rack mounts and internal cable routing

When was the last time you saw a bike at this price with internal cable routing? Interna; routing helps keep the cables safe and secured while also adding to the clean look of this frame.

There's also mounts for a rear rack if you want to carry more gear on your commute. There's even fender mounts for all-weather commuting.
