Key Specifications

• Battery and Range

  The Kavaki e-bike is powered by a high-capacity 48V lithium-ion battery, engineered for long-lasting performance and reliability. This detachable battery can be conveniently charged using a standard household outlet, making it easy to recharge at home, work, or on the go. With an average range of 40–60 miles (65–95 km) per full charge—depending on terrain, rider weight, and pedal assist level—the battery provides ample power for extended commutes, weekend tours, or trail exploration.

  The intelligent battery management system (BMS) protects against overcharging, deep discharge, and temperature extremes, helping preserve battery health. Riders can expect 500+ charge cycles with proper care, ensuring years of dependable use.

• Motor Power

  Equipped with a 250W rear or mid-drive motor, the Kavaki e-bike delivers efficient, responsive power that enhances pedaling effort without overwhelming the rider. This motor provides sufficient torque (typically 40–60 Nm) to conquer inclines up to 15% grade and maintain consistent speeds of 15–20 mph (25–32 km/h), depending on local e-bike regulations.

  The motor integrates seamlessly with the pedal-assist system (PAS), offering multiple assist levels (usually 3–5 modes) to customize your ride experience. Whether you're cruising on flat roads or tackling steep trails, the 250W motor balances energy efficiency with reliable performance, extending battery life while reducing rider fatigue.

• Tire Size

  One of the standout features of the Kavaki e-fat bike is its oversized 4-inch wide tires, typically available in 20"x4.0", 26"x4.0", or 27.5"x4.0" configurations. These fat tires provide exceptional traction, shock absorption, and flotation on soft or unstable surfaces such as sand, snow, mud, and gravel.

  Running at lower pressures (typically 10–15 PSI), the tires increase ground contact area, improving stability and control. They also reduce rolling resistance on rough terrain, resulting in a smoother, more comfortable ride. The robust tread patterns are designed for all-weather grip, making the bike suitable for year-round use in varied climates.

• Braking System

  Safety is prioritized with a high-performance braking system. Most Kavaki models come equipped with hydraulic disc brakes, while some variants feature mechanical disc brakes. Hydraulic systems offer superior modulation, consistent stopping power, and reduced maintenance compared to rim brakes.

  Large 180mm or 203mm rotors ensure rapid heat dissipation during prolonged descents, minimizing brake fade. The brakes perform reliably in wet, muddy, or snowy conditions, giving riders confidence during high-speed rides or technical trail sections. Many models also include motor cutoff sensors that disengage the motor when braking, enhancing control and safety.

• Weight Capacity

  The Kavaki e-fat bike is built with a reinforced aluminum alloy frame designed to support a maximum rider weight of approximately 300–330 lbs (136–150 kg), depending on the specific model. This robust construction ensures structural integrity, stability, and long-term durability, even under heavy loads or aggressive riding conditions.

  Exceeding the recommended weight limit can lead to accelerated wear on components such as the suspension, wheels, and drivetrain, and may void the warranty. Always consult the manufacturer’s manual for exact specifications and load guidelines to ensure safe and optimal performance.

Maintenance Tips

• Regular Battery Care

  To maximize battery lifespan and performance, avoid letting the charge drop below 20%. Fully discharging the battery regularly can degrade its internal cells over time. Ideally, recharge after each ride, even if not fully depleted.

  Store the battery in a cool, dry place (ideally between 50°F–77°F / 10°C–25°C). Avoid leaving it in direct sunlight, hot vehicles, or freezing conditions. If storing long-term, keep the charge level around 50–60% and check monthly. Use only the original charger to prevent damage and ensure compatibility.

• Tire Inspection

  Fat tires require regular inspection due to their size and exposure to rough terrain. Check tire pressure weekly using a reliable gauge—underinflation increases rolling resistance and risk of pinch flats, while overinflation reduces traction and comfort.

  Inspect tread for cuts, embedded thorns, or sidewall cracks. Remove debris like stones or glass from the treads. Rotate tires every 500–1,000 miles to promote even wear. Consider carrying a portable pump or CO₂ inflator for field repairs.

• Frame Care

  After each ride—especially in wet, muddy, or salty conditions—rinse the frame with clean water and mild detergent. Use a soft brush to remove dirt from hard-to-reach areas like the chainstay, bottom bracket, and motor housing.

  Avoid high-pressure washers, which can force water into bearings, electrical connections, and suspension components. Dry the bike thoroughly after cleaning. Periodically inspect for scratches, rust spots, or cracks, particularly around welds and mounting points. Touch up paint chips to prevent corrosion.

• Brake Maintenance

  Check brake pads monthly for wear; replace them when pad thickness drops below 2mm. Inspect rotors for warping, scoring, or oil contamination. Clean rotors with isopropyl alcohol and a lint-free cloth—never touch the surface with bare hands.

  Ensure brake levers have firm feel and adequate travel. If hydraulic brakes feel spongy, they may need bleeding. For mechanical systems, check cable tension and housing condition. Properly maintained brakes ensure reliable stopping power in all conditions.

• Gear Lubrication

  A well-lubricated drivetrain improves efficiency, reduces wear, and prevents rust. Clean the chain, cassette, and derailleur with a degreaser every 100–200 miles, then apply a high-quality, water-resistant lubricant.

  Wipe off excess lube to prevent dirt buildup. In dusty or off-road environments, consider using wax-based or dry lube to minimize grime accumulation. Re-lubricate more frequently in harsh conditions. Regular maintenance extends component life and ensures smooth shifting.

Expert Tip: Create a monthly maintenance checklist: inspect tires, test brakes, clean and lube the chain, check battery terminals, and tighten bolts (especially stem, handlebars, and wheel axles). A few minutes of routine care can prevent costly repairs and keep your Kavaki e-bike running like new for years.

Additional Recommendations

• Keep the owner’s manual and warranty information in a safe place for reference.
• Have your e-bike professionally serviced at least once a year, including motor diagnostics and firmware updates (if applicable).
• Use a bike cover or garage storage to protect against weather and UV damage.
• Monitor firmware updates from Kavaki for improved motor control or battery management.
• Register your e-bike with the manufacturer to receive support, recall notices, and service alerts.
