This document is an owner's manual for Nukeproof multi-speed bicycles, providing essential information for safe operation, maintenance, and fit. It emphasizes that cycling involves inherent risks of injury and damage, and riders assume responsibility for these risks by choosing to ride. The manual aims to guide users on proper use and maintenance to mitigate these risks.

The manual begins with a general warning about the risks of cycling and advises users to read the entire manual before their first ride. It also includes a special note for parents, highlighting their responsibility for ensuring their child's bicycle is properly fitted, in good repair, and that both parent and child understand safe operation and applicable laws. A crucial warning for children is to always wear an approved bicycle helmet when riding, but to remove it when not cycling, as wearing it during other activities can be dangerous.

The "Before You Ride" section covers critical pre-ride checks. It stresses the importance of proper bike fit, including standover height, saddle position, and handlebar height and angle. Users are advised to ensure their bike is the correct size, as an ill-fitting bike can lead to loss of control and falls. Saddle height and position are detailed, with instructions on how to check and adjust them for optimal performance and comfort. The manual warns that an improperly adjusted saddle can cause discomfort or injury. Handlebar height and angle adjustments are also covered, with a caution against exceeding maximum spacer height, which could damage the fork's steerer tube. Control lever positions and brake reach adjustments are explained to ensure comfortable and effective braking.

A "Mechanical Safety Check" is recommended before every ride. This includes checking the correct inflation and condition of tires and wheels, ensuring wheels are true, and verifying proper brake operation. The manual highlights that Nukeproof bikes are equipped with powerful disc brake systems, noting that power improves with use as pads and discs bed in. It also emphasizes checking quick releases for secure clamping and ensuring handlebars and saddle are aligned and securely tightened. Loose or damaged handlebar grips are identified as a hazard that can lead to loss of control. The rear derailleur hanger should also be checked for tightness, straightness, and damage.

The "First Ride" section advises riders to familiarize themselves with the bike's controls and performance in a controlled environment. It provides guidance on practicing braking and gear shifting, emphasizing the importance of progressive brake modulation to avoid wheel lock-up and falls. Riders are warned against shifting gears while pedaling backward, as this can jam the chain and damage the bicycle.

The "Safety" section delves into various aspects of riding safety. It reminds riders to comply with local laws, wear an approved helmet, and perform the mechanical safety check before each ride. Riders are advised to be familiar with their bike's controls, keep body parts away from moving components, and wear appropriate clothing and protective eyewear. The manual discourages jumping with the bike due to the stress it places on components and the increased risk of damage and injury. It also covers riding safety in general, emphasizing sharing the road, riding defensively, and being aware of potential hazards. Specific advice is given for wet weather riding, highlighting reduced traction and braking power, and night riding, which requires additional precautions like lights and reflective clothing.

For electric bikes (E-Bikes), a dedicated section outlines differences from pedal-operated bicycles, such as increased weight and altered handling characteristics. It stresses that E-Bikes require qualified mechanics for electrical system maintenance and warns against modifying the motor, which can void warranties and violate laws. Battery safety is a key focus, with detailed instructions on handling, charging, and transport to prevent overheating, bursting, or ignition.

The "Technical" section provides instructions for initial assembly, particularly for mail-order bikes, and lists necessary tools. It strongly recommends that an Authorized Nukeproof Dealer perform assembly and fitting due to the complexity and precision required. Wheel installation, including quick-release and through-axle systems, is explained with warnings about incorrect adjustment leading to serious injury. Brake controls and operation are detailed, emphasizing the importance of proper adjustment and familiarization with braking performance in different conditions. Gear shifting mechanisms are described, along with advice on how to shift effectively and choose appropriate gears. Pedal installation and the concept of "toe overlap" are also covered, with warnings about potential hazards. The section concludes with information on tire types, inflation, and maximum tire width, stressing the importance of correct tire pressure and avoiding over-inflation.

The "Service" section outlines recommended service intervals and maintenance tasks. It distinguishes between tasks that can be performed by the owner and those requiring a qualified mechanic. The manual emphasizes the importance of a "break-in period" for new bikes, during which cables and spokes may stretch and require readjustment. Regular checks after long or hard rides, or every 10-20 hours of riding, are recommended, including inspecting for loose headsets, wheel damage, and worn brake pads. The manual also provides guidance on what to do if the bike sustains an impact, advising a thorough check by an Authorized Nukeproof Dealer due to the risk of premature component fatigue. Finally, it discusses replacement parts, stressing the importance of selecting suitable, genuine parts and having them properly installed to maintain the bike's safety and performance characteristics.
