Climb effortlessly with this lightweight cycling machine.  The Prevelo Zulu Three packs high performance mountain bike features into a package for small riders. Every component is the real deal and is carefully chosen to provide the best performance and fit for young riders ready to tear up the trails.

The Prevelo Zulu Three Bike features:

  1. Prevelo confidence inspiring low and narrow geometry. Prevelo geometry keeps the rider low, balanced and in control.
  2. Lightweight 6061 aluminum frame with custom formed tubing.
  3. Air fork with lockout. This is a real air fork. Lightweight. Adjustable. Effective at soaking up harsh terrain.
  4. Hydraulic disc brakes with special short reach levers for little hands.
  5. Quick release front and rear wheels for toolless wheel removal.
  6. Three piece crank with squared taper bottom cartridge bearing bottom bracket and ultra narrow Q factor.
  7. Custom made cranks. All Prevelo cranks are sized specifically for each model bike, down to the millimeter.
  8. Shimano ZEE 10-speed drivetrain. This 10-speed derailleur has a SHIMANO Shadow RD+ Short cage. Because kids’ bikes have small wheel diameters, rear derailleurs on kids’ bikes hang low and close to the ground. The Prevelo Zulu bikes use high performance short cage derailleurs to keep things high and away from the ground. The derailleur also features a clutch that can be turned on with the flip of a switch to eliminate derailleur bounce over hard terrain and reduce chain drops.
  9. Shimano SLX RAPIDFIRE Plus Shift Lever. Reliable silky smooth shifting and easy for small hands to operate.
  10. Replaceable derailleur hanger. If the derailleur takes a hard hit, the hanger can be replaced without repair to the frame.
  11. 11-34T wide span gearing gives riders plenty of range to spin up tough hills.
  12. 95% assembled. Just install the handlebar, seatpost, front wheel and pedals.
