The Foundation of Control.

The Spherical Bearing Seat and kingpin assembly experience some of the highest loads anywhere on THE ONE. Proper torque values and threadlocker application are essential for maintaining steering precision, chassis integrity, and long-term reliability.

Assembly Best Practices

Whenever critical hardware is serviced, remove old threadlocker residue completely, apply fresh Loctite 243, tighten to the specified torque, and allow approximately 24 hours for curing before riding.

Proper bolt preload creates the clamping force that allows the entire steering assembly to function as a single rigid structure. Maintaining this preload is critical for steering consistency and durability under high loads.

Routine Inspection

• Verify critical fasteners periodically using a calibrated torque wrench.
• Inspect threaded interfaces whenever hardware is removed.
• Replace damaged or worn fasteners immediately.
• If a fastener repeatedly loses torque, inspect all related components before continuing to ride.

Performance Components Are Consumables.

Just as race cars, mountain bikes, and motocross machines require periodic servicing, THE ONE benefits from a comprehensive chassis inspection every 1,000 km (620 miles) of aggressive riding.

Bushings, Pivot Cups, Gearbox Buffers, and other damping components are intentionally designed to absorb energy and protect structural components. Regular inspection helps preserve ride quality, steering precision, and overall system longevity.

Recommended 1,000 km Inspection Checklist

• Inspect bushings for deformation, cracking, or excessive compression.
• Inspect Pivot Cups for wear and steering play.
• Inspect Spherical Bearings for smooth movement and proper fitment.
• Inspect Spherical Bearing Seats and kingpin threads for wear.
• Inspect critical hardware for corrosion or damage.
• Inspect Gearbox Buffers for excessive wear.

Fastener Replacement Recommendation

During major chassis servicing, Linnpower recommends replacing critical Spherical Bearing Seat and kingpin fasteners with fresh YFS 12.9-grade hardware. This helps maintain optimal clamping force and long-term reliability under repeated high-load use.

Built to Last. Designed to Be Serviced.

THE ONE's gear drive system was developed for high power output and long service life. Like all precision mechanical systems, routine maintenance is key to achieving maximum durability.

Gearbox Lubrication

Gearbox grease naturally degrades over time. Riders who accumulate high mileage should periodically inspect gearbox condition and replenish lubricant as needed.

• Inspect drivetrain noise after approximately 3,000 km.
• Add 5–6 grams of gearbox grease approximately every 5,000 km.
• Use only high-quality gearbox-specific grease.

Hub Bearing Inspection

At approximately 5,000 km, inspect wheel bearings for excessive play, rough rotation, clicking, or grinding noises.

Replacement specification: 16100-2RS

Motor Maintenance

Electric motors naturally attract fine metallic particles and road debris. Periodically cleaning the motor ventilation openings with compressed air helps maintain cooling efficiency and long-term reliability.

Major Gearbox Service

Following significant water exposure, contamination, or extremely high mileage, a complete gearbox service may be beneficial.

• Clean all contaminated grease from the gearbox housing.
• Inspect bearings, seals, and O-rings.
• Inspect gears for abnormal wear patterns.
• Reassemble using fresh grease and threadlocker.
• Torque all fasteners to specification.

Inspect Beyond the Point of Impact.

Any significant crash, collision, curb strike, or abnormal impact should be followed by a comprehensive inspection of the entire board.

Impact energy can travel throughout the chassis, suspension, drivetrain, and deck structure. Components far away from the visible impact point may still experience stress, deformation, or hidden damage.

Particular attention should be given to:

• Truck assemblies
• Spherical Bearing Seats
• Kingpins and structural fasteners
• Motor mounts
• Gearbox housings
• Deck mounting points
• Battery enclosure hardware

If the condition of a load-bearing component cannot be confidently verified, discontinue riding until a full inspection has been completed.
