Performance at a Glance

Key specifications that define the Y16 riding experience.

Intelligent Rear Hub Motor

Precision-engineered for seamless power delivery across diverse urban environments.

At the heart of the Y16 lies a high-performance rear hub motor that redefines what a city e-bike can accomplish. With a peak output of 1,000W and a rated continuous power of 750W, this brushless DC motor provides the ideal balance of torque and efficiency. Whether you’re accelerating from a standstill at a traffic light or climbing a moderate incline, the motor responds with smooth, predictable power that inspires confidence on every ride.

The rear hub configuration centralizes mass low and toward the back of the bike, enhancing traction on the rear wheel — especially beneficial when paired with the 4.0-inch fat tires. Riders can expect brisk acceleration that makes merging into city traffic feel effortless, while the motor’s quiet operation preserves the peace of early-morning commutes and late-evening rides alike. Advanced thermal management within the motor housing helps maintain consistent performance even during extended use, and the sealed construction resists moisture and dust ingress, contributing to long-term reliability.

48V 15Ah Lithium Battery System

High-density energy storage with rapid charging for maximum uptime.

Powering the Y16 is a 48-volt, 15 amp-hour lithium battery with a total energy capacity of 720 watt-hours. This premium battery pack utilizes advanced lithium-ion cell technology to deliver consistent voltage output throughout the discharge cycle, meaning you’ll experience strong performance from the first mile to the last. Under typical riding conditions with a mix of pedal assist and throttle use, riders can expect a range exceeding 37 miles (60+ km) on a single charge — more than enough for most daily commutes, errand runs, or leisurely weekend explorations.

One of the standout features of the Y16 battery system is its rapid charging capability. With a full recharge achieved in under 3 hours, the bike spends less time tethered to an outlet and more time on the road. This fast-charge performance is ideal for office commuters who can top up during the workday, or for riders planning back-to-back outings without lengthy downtime. The battery housing is seamlessly integrated into the bike’s frame design, maintaining clean aesthetics while protecting the cells from environmental exposure. A sophisticated Battery Management System (BMS) continuously monitors voltage, temperature, and current to safeguard against overcharging, overheating, and short circuits.

Hiten Steel Frame & Urban Design

A foundation of strength, comfort, and timeless city-bike aesthetics.

The Y16 is built around a robust Hiten steel frame — a material renowned in the cycling world for its exceptional strength-to-weight ratio and natural vibration-damping properties. Unlike aluminum frames that can transmit road buzz directly to the rider, Hiten steel absorbs micro-vibrations from uneven pavement, contributing to a noticeably smoother and more comfortable ride over long distances. The frame geometry is carefully calculated to provide an upright, relaxed riding posture that reduces strain on the back and shoulders, making the Y16 an ideal companion for daily commuting, casual cruising, and everything in between.

With a maximum payload capacity of 265 lbs (120 kg), the Y16 accommodates a wide spectrum of riders and cargo configurations. The sturdy frame construction, reinforced weld points, and heavy-duty components work in concert to ensure structural integrity under load. Additionally, the bike offers customizable logo options, allowing riders, fleets, or businesses to personalize their Y16 with branding or unique design accents — a thoughtful feature for corporate campuses, rental operators, or anyone seeking a distinctive look.

16-Inch Wheels & 4.0-Inch Fat Tires

Uncompromising traction, stability, and versatility across changing terrain.

The Y16 rides on 16-inch wheels wrapped in 4.0-inch wide fat tires — a combination that delivers an expansive contact patch for superior grip on pavement, gravel, packed dirt, and even light sand or snow. These oversized tires act as natural shock absorbers, cushioning the ride over potholes, curbs, and uneven surfaces without the complexity of a suspension system. The increased air volume allows for lower tire pressures, which further enhances comfort and traction while reducing the risk of pinch flats.

Whether navigating rain-slicked city streets or venturing onto a gravel pathway through a park, the fat tire footprint inspires confidence. The aggressive tread pattern is optimized for urban use — providing efficient rolling on hard surfaces while retaining enough bite for loose conditions. This versatility makes the Y16 a true all-terrain city bike, equally at home on a bike lane as it is on a recreational trail.

Disc Brake System

Precision stopping power engineered for all-weather reliability.

Safety is paramount in urban riding, and the Y16 delivers with a front and rear disc brake system that provides consistent, powerful stopping performance in both dry and wet conditions. Unlike traditional rim brakes that can lose effectiveness when rims are wet or muddy, disc brakes maintain their bite regardless of weather, giving you dependable control when you need it most. The disc rotor design dissipates heat efficiently during prolonged braking, reducing fade on long descents or during stop-and-go city traffic.

The braking feel is progressive and intuitive — light lever pressure yields gentle speed modulation, while a firmer squeeze brings the bike to a swift, controlled stop. This predictable response is especially valuable in urban environments where sudden stops may be necessary. Combined with the fat tires’ ample grip, the disc brake system forms a comprehensive safety package that keeps you in command of every ride.

7-Speed Gear System

Adaptable gearing for flat sprints, rolling hills, and everything between.

The Y16 is equipped with a 7-speed drivetrain that puts the right gear ratio at your fingertips. On flat city streets, shift into higher gears to maintain efficient cruising speed with the motor’s assistance. When the terrain rises, drop into lower gears to optimize torque and preserve battery range. This mechanical gear range complements the electric motor beautifully, allowing you to fine-tune your pedaling effort to match conditions, fitness level, and desired workout intensity.

The shift action is crisp and reliable, with clearly indexed positions that let you change gears confidently without looking down. Whether you’re accelerating from a stop on an incline or spinning comfortably along a riverside path, the 7-speed system ensures you always have an appropriate gear ready. This level of control also contributes to extended range, as efficient pedaling in the optimal gear reduces unnecessary drain on the battery.

The Urban Riding Experience

How the Y16 transforms everyday journeys into something extraordinary.

From the moment you swing a leg over the Y16, the bike communicates a sense of solidity and readiness. The upright seating position provides excellent visibility in traffic — you sit high enough to see over most sedans, giving you a commanding view of the road ahead. The wide handlebars offer leverage for precise steering inputs, while the broad saddle and ergonomic grips minimize pressure points during extended rides. This is a bike that feels equally at home on a 2-mile coffee run as it does on a 20-mile weekend exploration.

Acceleration is smooth and linear — the rear hub motor delivers power in a progressive manner that never feels abrupt or unsettling. As speed builds, the fat tires hum quietly beneath you, their substantial air volume absorbing surface imperfections that would rattle a lesser bike. In urban stop-and-go conditions, the responsive disc brakes and instant motor engagement make navigating traffic feel intuitive rather than stressful. The 7-speed gear range ensures you can always find a comfortable cadence, whether climbing a bridge approach or cruising a flat boulevard. Taken together, the Y16 delivers a riding experience that is engaging, confidence-inspiring, and genuinely enjoyable.
