Aipas AMP Electric Dirt Bike - S1-BK

The Aipas S1 AMP is a 4000W electric dirt bike for adults who want serious off-road power, fast acceleration, and full-suspension control. With 255 Nm of torque, a 50 mph top speed, and a 60V 28Ah removable battery, the S1 AMP is built for dirt tracks, trails, gravel, steep climbs, and open outdoor riding.

Unlike a standard commuter ebike, the S1 AMP is designed around dirt-bike-style performance. Its mid-drive motor, full suspension system, hydraulic braking setup, high-output lighting, and compact dirt-bike-style frame make it a stronger fit for adult riders who want high torque, responsive control, and more off-road capability.

4000W Power for Off-Road Riding

At the core of the S1 AMP is a 4000W mid-drive motor designed for strong acceleration and high-torque riding. With up to 255 Nm of torque and a max 70° gradient rating, this electric dirt bike gives adult riders the power needed for steep climbs, loose terrain, and demanding off-road routes.

This setup makes the S1 AMP better suited for trails, dirt tracks, gravel paths, open outdoor areas, and private off-road routes than for ordinary city commuting.

60V 28Ah Battery for Longer Outdoor Sessions

The removable 60V 28Ah lithium battery provides up to 60 miles of electric-only range on a single charge. It supports longer trail sessions, outdoor riding, and extended off-road use while allowing easier charging at home or on the go.

For adult riders who want an electric dirt bike with both high output and practical range, this battery setup helps balance power, distance, and riding flexibility.

Three Riding Modes for Different Terrain

The S1 AMP includes three power modes so riders can adjust output based on terrain and riding style.

Maintenance Tips

• Battery care (60V 28Ah removable): Charge after each ride, avoid full deep discharge, and store at ~50% charge for long breaks. Keep battery dry and away from heat or freezing temperatures.
• Tire pressure (14”/12” dirt setup): Check before every ride. Maintain proper PSI for terrain (lower for trails, higher for hard ground) to improve traction and reduce flats.
• Chain & drivetrain: Clean and lubricate every 100–150 km or after mud/wet riding. This protects the 420 chain system and ensures smooth power transfer.
• Brake system (hydraulic discs): Inspect pads regularly and replace when worn. Bleed brakes if lever feels soft to maintain strong stopping power at high speeds.
• Suspension maintenance: Check dual-crown front fork and rear shock for leaks or stiffness. Clean stanchions after off-road use to preserve damping performance.
• Bolt & frame checks: Tighten axle, stem, and suspension bolts every 2–3 weeks due to high vibration from off-road riding.
• Electrical system: Keep controller, display, and wiring clean and dry. Inspect connectors for looseness or corrosion monthly.
• Cooling & usage habits: Avoid long full-throttle climbs in extreme heat to prevent motor/controller overheating.
• Cleaning routine: Use low-pressure water or damp cloth only. Avoid pressure washing near motor, battery housing, and electronics.
• Storage: Store indoors or under cover. Remove battery if storing long-term to extend lifespan.
