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!
