Bike info

The Metropolis 3 is the most affordable bike in the range and could be your first proper dirt bike. Rest assured, the nice price doesn’t mean you will be losing out on any fun - this is one hell of an exhilarating ride. The 2021 edition gets a strong cromoly frame that’s double-butted upfront to reinforce it where most needed, namely the headtube area. Like its siblings, the geometry is based on the high-end Decade used by the whole NS Bikes freeride team. The tapered headtube will let you upgrade the fork when the time comes.  
Cromoly / hi-ten frame
RST Dirt 100m fork
Salt by WTP crankset
Sealed bearing hubs, 10t driver
NS Bikes aftermarket cockpit
Alhonga V-brakes

If you love the timeless, unique quality of cromoly then look no further and check out the bikes in the ever-popular Metropolis range. Steel tubes and a svelte aesthetic work with geometry developed by the best riders in the world. For 2021 the bikes in the range have been upgraded and now feature new frames in all the models, with tapered head tubes and refined geometry based on the award-winning NS decade frames.



”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
