NS Bikes Releases the Define AL 170

Apr 2021 · NS Bikes

We selfishly made the Define 170 for the riding we most enjoy. It is perfect for big jumps and severe terrain, and it is happy on the uphills, too. It is the most aggressive bike in the Define range, but one that is still fun to ride everywhere. Enduro, freeride, bike park ripper, call it what you like – at NS, a company of riders, we have fallen in love with this beast.

[R]eviewed // NS Bikes Define 150

Sep 2020 · September 2, 2020

To begin with, was there ever really any doubt from the brand who originally put themselves on the map for creating  amazing dirt jump hardtails that their latest enduro rig wasn’t going to be one of the most playful bikes of 2020?  That’s pretty much it in a ‘nutshell’ really!

NS Define 150 AL review

May 2020 · Robin Weaver

The Define 150 AL is packed full of promise and has great geometry. It’s not quite as comfy as some and the spec does fall a little short in places

Highs
  • Great geometry

  • Confident feel to the rear suspension

  • Functional spec that’ll do the job

Lows
  • Niggling issues with some elements of the spec

  • Not the comfiest ride on really rough descents
