Glows in the Dark

Be seen, be safe. And never be forgotten.


Get ready to take your night riding to a whole new level. After months of experimentation, we've perfected the GLOW, our newest line. The name says it all, it actually glows. The paint is solar-activated, so just give your bike an hour of daytime sun for an hour plus of night-time fun. Whether you're a night owl, a raver, or just want to trip out your friends, this is the bike for you.

Full Original Fixed Gear Bike Specifications

The best warranty in the business

We believe in our bikes and we believe you should be able to enjoy riding without sweating the small stuff - that’s why we’ve got your back! With a lifetime warranty on frames and a 1-year warranty on components, you can ride confidently with the knowledge that we’ve got you covered.

To activate your warranty, professional assembly is required.

Fixed Gear or Freewheel?

We chose a flip-flop rear hub to give you the flexibility to ride fixed or freewheel. Riding fixed gives you an unmatched feeling of connectedness to the bike, the road, and helps you perfect your pedal-stroke. Riding freewheel gives you the ability to coast and cruise, just like the single-speed you grew up on! No matter which you choose to ride, the standard front brake guarantees you can stop either way.

We love happy customers!

If you’re not happy, we’re not happy, and if we’re not happy, why are we doing this? We want you to love your bike and your Pure Fix experience as much as we love you!

Stay visible

Visibility is important. Style is essential. Whether you’re trying to be seen or be seen, the Glow Series will light up your rides and get you exactly where you want to be. An hour of charging in the light gives you an hour of glowing in the streets. Be seen, be safe, and liven up your ride!

Sizing Chart

This is a rough guideline and we recommend everyone get fitted at their local bike shop. For a quick guesstimate measure your inseam to the floor and select the size with a standover height about 1"-2" shorter than your inseam. Or, you know, go visit your local bike shop! You can also shop by size.
