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. With 24" wheels designed around kids, the metric 24 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 1 x 8 speed drivetrain and alloy v-brakes, the Metric 24 will easily establish a place for itself in your child's life.


  • Upright, stable geometry establishes a fun and confidence inspiring ride experience
  • 24" wheels roll fast while 1.75" tires provides enough air volume to soak up unwanted road chatter
  • Aluminum V-Brakes are consistent and predictable 
  • Simplistic 1 x 8 speed drivetrain is easy to use
