WARNINGS AND IMPORTANT INFORMATION
ATTENTION: Please read this manual carefully. It contains important safety information
WARNING: Extreme riding is a very dangerous sport it requires an amazing amount of skill. By engaging in this type of
activity, you are accepting the risk of possible injury or even death. Even the best bike will not help you land a clean trick if you
lack the skills. Even the best protective gear will not guarantee complete safety. Remember that in this kind of riding, you can
only trust your own abilities and you must accept the inherent risk. While riding you can reach significant speeds and there-
fore face significant hazards and risks. Inspect your bicycle and equipment carefully and be sure that it is in perfect condition
before each ride. If possible consult with area site personnel, expert riders and race officials on conditions and equipment
advisable. Always wear appropriate safety gear, including an approved full face helmet, full finger gloves, body armour, bright,
visible clothing that is not so loose that it can be tangled in the bicycle or objects at the side of the road or trail, shoes that will
stay on your feet and will grip the pedals (make sure that shoelaces cannot get into moving parts, and never ride barefoot or
in sandals. Always use protective eyewear, to protect against dirt, dust and bugs.
WARNING: Some of the service procedures require specialist tools and good mechanical skills. Therefore, to minimize the
risk of serious or even fatal accidents, maintenance and assembly work on your bike should be carried out by an authorized
bicycle workshop.
IMPORTANT NOTICE This manual is not intended as a comprehensive use, service, repair or maintenance manual. Please
consult your dealer for advice and your dealer may also be able to refer you to classes, clinics or books on bicycle use, ser-
vice, repair or maintenance.
WARNING: The frame box contains instructions for components made by third parties. You must study these carefully and
follow the directions before riding your bike. Make sure you read and follow the suspension setup and service instruction
manual provided by the manufacturer. If the instruction manual has not been provided, please contact your dealer or the
manufacturer.
WARNING: Failure to maintain, check and properly adjust the suspension system may cause suspension malfunction, in
result of which you may lose control and fall.
WARNING: Introducing changes in the suspension adjustment can alter the handling and braking characteristics of your
bicycle. It is forbidden to change the suspension adjustment unless you are thoroughly familiar with the suspension system
manufacturer’s instructions and recommendations you should always check for changes in the handling and braking char-
acteristics of the bicycle after the suspension has been adjusted by taking a careful test ride in a safe area.
WARNING: As with all mechanical components, the frame is subjected to wear and high stresses. Different materials and
components may react to wear or stress fatigue indifferent ways. If the design life of a component has been exceeded, it
may suddenly fail possibly causing injuries to rider. Any form of crack, scratches or change of colour in highly stressed areas
indicate that the life of the component has been reached and it should be replaced.

GENERAL RIDING INFORMATION
Riding a bicycle can be dangerous. You must keep this in mind and be cautious at all times.
See and be seen. Use lights and reflective clothing in low light conditions.
Always wear a helmet when riding. It can save your life.
Always conduct a pre-ride check (detailed information can be found further in this manual).
Never ride the bicycle if you observe any technical problems or have any doubts about the proper functioning of any ele-
ments in the bicycle.
Keep the bike clean and well maintained.
Carry a pump, spare inner tube, patch kit, and a basic toolkit- you may need this in the case of a flat tire of other common
mechanical problem that is usually easy to fix if you have the right tools. Ask your dealer for advice on this issue.
If your bicycle is equipped with gears, you can choose a gear combination that is most comfortable for the riding conditions.
Gears will allow you to maintain a constant rate of pedaling. Use lower gears forgoing uphill and higher gears forgoing down-
hill. Ease upon your pedaling pressure when you shift gears. Ask your dealer to give you more advice on this issue.
Be careful with the brakes - they can be powerful and if activated too aggressively, may cause a crash. You should spend
some time to get a better feel of the brakes on aside road or empty parking lot before the first ride. Avoid riding too fast,
especially downhill. It is easy to loose control of the bicycle and crash at high speeds, and also you will find it very difficult to
slow down especially if the hill is steep.
If your bike has been equipped with suspension, the increased speed you may develop will also increase the risk of injury. For
example, front of the bike may dive on the suspension fork while hard braking. You can easily lose control and fall if you are
not prepared for this. Please, learn how to operate your suspension system safely.
Thanks to the suspension the wheels can follow the terrain better, which improves control and comfort. This improved
capacity may provide opportunity for riding faster, but you should be careful not to mistake the enhanced capabilities of the
bicycle for your own riding skills. Improving skills takes time and practice.
Protect your bike from theft. Purchase a lock and never leave your bike unlocked while unattended, even if you are planning to
be away from it for just a few minutes.

INTRODUCTION
Thank you for choosing NS Bikes. We are passing into your hands a frame that has been a milestone in the development of
our company. We have worked on it passionately for well over 2 years, gone through countless prototypes, tested each one
by our team riders and reworked it untill everything got dialled.
Seeing satisfied customers is the biggest reward that we can get for this working hard. So we did everything in our power to
make this happen, but even then, a product that is not properly setup or maintained will be a disappointment. That is why it’s
so important that you acquaint yourself with this manual before your first ride.

We hope that you will be just as happy riding your new FUZZ as we are
FRAME CONCEPT & INFORMATION
The Fuzz is a true DH machine built to compete with the best in the pits, yet it is a modern do-it-all rig for any gravity assisted
riding. The bike has been thrashed by Sam Pilgrim at events like Rampage and proved itself in the real racing environment too,
taking podiums at major UCI events, piloted by the Polish DH star Slawek Lukasik. The frame has truly modern DH geometry - it’s
low, slack, and has a very short rear end with a roomy front triangle. The bar Horst link suspension has a significant amount of
rearward axle movement which helps to absorb square faced bumps. Unlike most other designs on the market (including virtual
pivot designs) it is immune to brake jack. There is also a fair amount of anti-squat built into the design to counter pedal-induced
bob. The shock, which is the most heavy part of the frame is tucked away near the BB to keep the centre of gravity as low as
possible.
For the coming season, the Fuzz frame has been redesigned to run on 27.5” wheels. We also increased the reach on this already
long frame.
Geometry: The frame has truly modern DH geometry - it’s low, slack, and has a very short rear end with a roomy front triangle.
Thanks to the adjustable dropouts you can setup the bike with a super tight rear end or you can fit the wheel in a more standard
position to suit the characteristics for any track and riding style. The short position results in one of the tightest rear ends on the
market. Thanks to this we could really open up the front end and benefit from massive stability and confidence improvements,
yet still keep the wheelbase (hence manoeuvrability) under control.

Suspension & kinematics the Fuzz has a clearly progressive leverage ratio curve. The first stage of the travel is very supple and
absorbs small and medium impacts. Towards the end of the travel, the frame becomes stiffer, and gives the rider a feeling of
support, which results in predictable launches off jump lips and other obstacles that require getting air to clear. It’s important to
note that the characteristics are different on the short and long setting with a noticeably softer and less progressive feel in the
long setting. The bar Horst link suspension has a significant amount of rearward axle movement which helps to absorb square
faced bumps. The system, unlike most other designs on the market (including virtual pivot designs) it is immune to brake jack
(i.e. the torque generated by the brakes will not cause the suspension to stiffen. There is also a fair amount of anti-squat built
into the design to counter pedal induced bob. The shock, which is the most heavy part of the frame is tucked away near the BB to
keep the centre of gravity as low as possible.
