Product Overview

The Vivi ACE01 Electric Bike for Adults is a high-performance e-bike designed for riders who demand power, comfort, and versatility on all types of terrain. Built with a robust aluminum alloy frame and featuring a 1500W peak motor, this fat tire electric mountain bike delivers exceptional speed and torque to conquer hills, sandy trails, snowy paths, and rocky mountain routes with confidence. Ideal for daily commutes, weekend adventures, or off-road exploration, the ACE01 combines advanced technology with user-friendly features to enhance every ride.

Key Features

• Powerful 1500W Peak Motor: Equipped with a high-speed rated 750W motor capable of delivering 1500W peak power and 90Nm of torque, this electric bike accelerates smoothly and handles steep inclines effortlessly. It reaches a top speed of 25 mph, making it suitable for both urban commuting and rugged trail riding.
• Removable 48V 15Ah Battery: The e-bike includes a long-lasting lithium-ion battery using premium 21700 cells that provide a range of 40–60 miles per full charge. The battery can be charged on or off the frame for added convenience, and it fully charges in just 4–6 hours using the included 3A charger.
• Torque Sensor Technology: Unlike standard cadence sensors, the integrated torque sensor detects pedal force and adjusts motor assistance proportionally. This results in a more natural, responsive ride—more power when climbing, less when descending or cruising—improving efficiency, control, and overall safety.
• All-Terrain Fat Tires: Featuring 26″ x 4.0″ wide, wear-resistant tires, the ACE01 offers superior grip and stability across sand, snow, gravel, mud, and paved roads. The large contact patch ensures reliable traction even in loose or slippery conditions.
• Premium Braking & Suspension: Dual hydraulic disc brakes deliver strong, reliable stopping power with minimal effort, while the adjustable front suspension fork absorbs shocks and enhances comfort on rough terrain.
• Seven-Speed Gear System: A professional-grade transmission allows precise gear adjustments to match varying terrain and riding conditions, ensuring optimal performance whether you’re pedaling uphill or speeding downhill.
• Five Riding Modes: Choose from five distinct modes: pure electric (throttle-only), pedal-assist (with five levels), traditional bicycle, cruise control, and walking assist. This flexibility makes the bike adaptable to different needs and environments.
• Adjustable Design & High Weight Capacity: The seat height is highly adjustable to fit riders between 5’3″ and 6’5″, and the sturdy frame supports users up to 330 lbs, offering broad compatibility and durability.
• LCD Display Screen: An easy-to-read digital interface shows real-time data including current speed, total mileage, selected pedal assist level, and remaining battery percentage, helping you monitor your journey at a glance.
• Easy Assembly & Reliable Support: The bike arrives 85% pre-assembled, allowing most customers to complete setup quickly using the provided instructions. It comes with a one-year warranty covering the motor, battery, and controller for peace of mind.

Important Notes

The electric bike ships 85% assembled and requires basic assembly before first use—follow the included manual for safe setup. A one-year warranty covers defects in the motor, battery, and controller components. Always inspect brakes and tire pressure before each ride. The battery must be stored in a cool, dry place when not in use and should only be charged with the provided 3A charger. While the bike is certified to UL 2849 (electric bicycles) and UL 2271 (lithium batteries), proper handling and maintenance are essential to ensure longevity and safe operation. Riders should always wear appropriate protective gear during use.
