Description
Product Overview
The Skeri ET04 is a purpose‑built electric tricycle that merges high‑performance engineering with practical urban design. At its heart lies a robust 500W front motor capable of delivering a peak output of 1000W, giving riders confident acceleration on hills, tight city corners, and mixed‑terrain paths. Power is supplied by a 48V 13Ah lithium‑ion battery, a removable pack rated at 624 Wh, which translates to an impressive 50‑mile range under typical mixed‑use conditions. The battery is UL‑certified, quick‑swap, and positioned low in the frame to maintain a low centre of gravity, enhancing stability and handling.
The chassis is constructed from high‑strength aluminum alloy, offering a lightweight yet durable skeleton that folds neatly for storage. When folded, the tricycle measures just 72 × 36 × 12 inches, making it suitable for apartment living, car trunks, or public transport. The 20‑inch by 1.95‑inch all‑terrain tires are mounted on a rigid suspension system, providing a smooth ride over potholes, gravel, and light off‑road surfaces while keeping the overall weight manageable. Hydraulic disc brakes on both the front and rear wheels deliver reliable stopping power in wet or dry conditions, and the rear differential system allows each rear wheel to rotate independently, ensuring smooth cornering and reduced tire wear.
Additional features include a sturdy steel basket for cargo, a low‑step frame for easy mounting, and a user‑friendly control panel that offers five pedal‑assist (PAS) levels plus three throttle‑only modes. The ET04 complies with relevant safety standards and comes with a two‑year manufacturer warranty covering the motor, battery, and frame. All components are engineered for low maintenance, and the tricycle arrives partially assembled, requiring only a few minutes of final setup.

Usage
The Skeri ET04 is designed for a wide range of everyday scenarios. Urban commuters will appreciate the ability to zip through traffic, bypass parking constraints, and arrive at work or school with a fresh, sweat‑free experience. The removable battery means you can charge the pack indoors, at work, or at a café, while the tricycle itself can be folded and stored under a desk or in a closet. For weekend explorers, the 20‑inch all‑terrain tires and robust motor provide confidence on park trails, boardwalks, and light off‑road routes, allowing you to cover longer distances without fatigue.
Families and grocery shoppers benefit from the integrated basket, which can hold groceries, a small pet carrier, or other daily essentials. The low‑step frame and stable three‑wheel layout make mounting and dismounting effortless for riders of all ages, including those with limited mobility. The tricycle’s quiet electric drive is ideal for residential neighborhoods, campuses, and indoor facilities where noise restrictions apply. Whether you are navigating crowded city sidewalks, cruising along a suburban bike lane, or enjoying a leisurely ride through a park, the ET04 adapts to your pace and terrain, delivering a comfortable and reliable experience.

FAQ
What is the charging time for the battery?
The 48V 13Ah battery typically reaches a full charge in 4 to 6 hours when using the supplied charger. Charging time may vary slightly based on ambient temperature and the remaining charge level.
Can the battery be replaced with a higher‑capacity pack?
Yes, the ET04 is designed with a modular battery compartment that accepts compatible higher‑capacity packs from Skeri. Upgrading to a larger pack can extend range, but it may affect overall weight and handling.
Is the tricycle suitable for riders over 6 feet tall?
The medium frame size is optimized for riders up to approximately 6 feet tall. Taller riders may find the seat height comfortable, but the overall geometry is best suited for the adult size range specified in the product details.
How does the rear differential improve riding stability?
The rear differential allows each rear wheel to rotate independently, which reduces tire scrubbing during turns and provides smoother handling on uneven surfaces. This technology enhances traction and reduces wear on the tires.
What maintenance is required for the hydraulic disc brakes?
Hydraulic disc brakes require minimal maintenance. Periodic inspection of brake pads for wear, cleaning the rotors with a non‑abrasive cleaner, and checking fluid levels annually will keep the system performing optimally.
