NS Bikes Metropolis 3 Green – 26" Dirt Jump Bike
The NS Bikes Metropolis 3 Green is a dedicated 26-inch dirt jump bike built for riders who want a simple, durable, and responsive platform for jumps, pump tracks, skateparks, and street riding. It combines a 4130 chromoly/Hi-Ten steel frame, 100mm suspension fork, compact dirt-jump geometry, and a straightforward single-speed drivetrain.
The Metropolis 3 sits at the accessible end of NS Bikes' dirt-jump range, but its geometry is derived from the company's higher-level Decade/Majesty platforms. The result is a bike designed around control, maneuverability, and confidence rather than unnecessary complexity.

Built for Dirt Jumping
The Metropolis 3 is designed around the demands of dirt jumping. Its compact geometry helps make the bike quick to move through takeoffs, manuals, jumps, and transitions, while the relatively short 381mm chainstay contributes to a playful and maneuverable feel.
NS Bikes bases the Metropolis geometry on its Decade/Majesty family of dirt bikes, giving the more affordable Metropolis 3 a geometry philosophy developed around aggressive jumping and park riding.
Chromoly / Hi-Ten Frame
At the heart of the bike is an NS Bikes 4130 chromoly / Hi-Ten frame with a tapered integrated head tube. The frame is double-butted in the front area to reinforce the head-tube section while maintaining the slim steel-tube appearance associated with the Metropolis range.
The one-size frame has a 405mm reach, 381mm chainstay, and 1028mm wheelbase, creating a compact platform suited to airborne riding and quick handling.
100mm RST Dirt Suspension Fork
The RST Dirt T fork provides 100mm of travel, giving the front end additional support when approaching jumps and absorbing impacts from landings.
The fork uses a 9mm axle and 1-1/8-inch steerer according to the official 2024 specification.
Simple Single-Speed Drivetrain
The Metropolis 3 avoids unnecessary gears and derailleurs in favor of a compact single-speed setup.
The drivetrain features:
Salt by WTP tubular chromoly crankset
25T chainring
Salt by WTP Spanish bottom bracket
PYC-510H single-speed chain
10T rear driver
NS Bikes 135 × 10mm single-speed rear hub
This arrangement keeps the drivetrain clean and straightforward, making it particularly appropriate for dirt jumps, pump tracks, and skateparks.
Braking System
The bike uses a combination of front V-braking and rear disc braking.
At the rear, the Tektro MD-M280 Aries 160mm disc brake provides controlled braking for slowing down before transitions and managing speed after jumps. The front uses an Alhonga V-brake, keeping the overall setup simple and easy to maintain.
26-Inch Wheels and Kenda Tires
The Metropolis 3 rolls on 26-inch wheels, with a Jalco DBX rim at the front and an NS Fundamental rim at the rear. Both are 32-hole designs.
Kenda Small Block 8 26 × 2.1-inch tires provide the contact with the ground. Their relatively compact profile suits the bike's dirt-jump focus and keeps the handling responsive.
Dirt-Jump Cockpit
The cockpit is made up of NS Bikes components selected for the bike's intended riding style:
NS Chemical 25.4 stem
NS Lick 740mm handlebar
NS Hold Fast Unlocked grips
Octane One fat seatpost and saddle combination
NS Nylon pedals
The 740mm handlebar and compact stem help provide a direct, controllable feel when maneuvering the bike through jumps and tricks.

Why Choose the NS Bikes Metropolis 3?
The Metropolis 3 Green focuses on the essentials of dirt-jump riding. Its chromoly-based frame, 100mm suspension fork, compact geometry, single-speed drivetrain, and 26-inch wheels create a bike that is easy to understand and purpose-built for jumping.
For riders who want a dedicated dirt bike without the added complexity of multiple gears or trail-oriented equipment, the Metropolis 3 offers a straightforward platform for learning tricks, improving jump technique, and enjoying pump tracks and parks.
Model-year note: Metropolis 3 specifications have changed over the years. For example, the 2021 model used a similar 4130 chromoly/Hi-Ten frame and 100mm RST fork but had a Tektro MD-M300 rear brake, while the 2024 specification uses the Tektro MD-M280 Aries rear brake.
