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.
