Going full roadie can be daunting, so Diamondback took the efficiency of a road bike platform and made a few tweaks to produce the Metric fitness bike. Based on 700c wheels, it rolls fast and efficient, yet incorporates a flatbar and upright riding position to increase comfort and stability for the average rider. Paired with a Shimano 3 x 8 speed drivetrain, alloy v-brakes, and integrated rack and fender mounts, the Metric will easily establish a place for itself in your life.


  • Upright, stable geometry establishes a fun and confidence inspiring ride experience
  • 700c wheels roll fast while 35c tires provides enough air volume to soak up unwanted road chatter
  • 3 x 8 speed drivetrain has a wide range of gear options for flat road or steep climbs 
  • Aluminum V-Brakes are consistent and predictable 
  • Integrated rack and fender mounts
