Micro Original Series

Just like the bikes that started it all - we took our Original Series and scaled it down for a smaller rider. That means smaller wheels and a smaller frame, but they'll ride just like their larger counterparts. 

Speed, style, and simplicity make these bikes the perfect storm of awesome whether you’re starting out, getting back into biking after a few years away, or just want to get a feel for riding fixed!

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.
