Bike info

Awesome ride quality of steel tubes and classic slim look - this is the bike to go for if you love cromoly. The Metropolis has all the features of a modern pro-level dirt bike, with geometry and parts that have been chosen by our top riders. You can take it straight out of the box and head to Mellowpark to practice your 360 nosedives, or even go for a big backflip at a Crankworx event. If you are not planning to go so far, hit the streets and practice some off-the-bank tailwhips. The bike is ready for this kind of stuff because it has all the features of a modern pro-level dirt bike. We have years of experience in building dirt bikes and believe that this is one of the best out there.

Hey, we are NS Bikes. Nuff said. Dirt bikes are our heritage. This is what we grew up with, this is what put our company on the map. Take any of these bikes out of the box, hit the trails and rip like there's no tomorrow. We have a whole range of aluminium and steel hardtails for any pocket, plus a unique full suspension bike for the biggest jumps.



”There aren’t many companies, whose entire product range is designed around getting rad, ripping corners and boosting jumps. The Polish brand have gained their reputation by building heavy-hitting, well speced and reasonably priced bikes.”  - MBUK
