Summary

The Orange Four trail bike is celebrated for its dynamic and playful trail feel, thanks to its refined single pivot suspension and intuitive handling. It's lighter than some carbon bikes, with improvements in frame construction and suspension progression enhancing its ride quality and efficiency. While it excels in fun and capability, some note the absence of a bottle cage mount and issues with the dropper post.

Pros
  • Refined single pivot suspension

  • Lighter than some carbon bikes

  • Intuitive handling and playful trail feel

  • Improved frame construction and suspension progression

  • Top-quality components

Cons
  • No bottle cage mount

  • KS dropper post prone to sticking

  • Thinner material is inherently more flexible

Key Quotes
The intuitive interaction between pedal pressure stiffening the suspension and steepening the angles and conversely relaxing your drive and the bike, gives it a deliciously dynamic and infectiously playful trail feel.

Orange Four RS Review

Oct 2016 · Isac Paddock

The new Orange Four was released earlier this season upon the world, a shorter travel bike than the iconic Orange Five, it claims an amazingly capable feel from just 120 mm of travel. The generous choice of colours, revolutionised geometry and good old British manufacturing make it look viable on paper, but how would it […]
