NS Bikes Define AL 170 is a big-hitting aluminium enduro bike with 180mm front and 170mm rear travelMullet wheels mix a 29in front and 27.5in rear.
Modern geometry and sizing. Excellent suspension components and tyres. Recessed cabling looks sleek but without the hassle of proper internal routing.
Rides like a shorter-travel bike.

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.
