Note: The Furious Shadow typically ships as a Class 2 eBike, but its motor and controller configuration allow for significantly higher speeds when unrestricted. While some official specifications mention an 8-speed Shimano Acera derailleur, user reviews and other product pages consistently cite a 7-speed system. Brake rotor size is generally stated as 180mm, although some general Furious component lists mention 203mm floating rotors on other models. The manufacturer states "Instruction Manuals" and "Video Tutorials" are "Coming Soon!" on their website, which could impact initial assembly guidance.

Design & Ergonomics

The Furious Shadow boasts a distinctive scrambler or moped-style design, characterized by a heavy-duty and robust frame. It features eye-catching mag wheels and aggressive-looking 20" x 4" Kenda Krusade fat tires that are surprisingly quiet on pavement. The bike is equipped with a Mozo dual-crown front suspension fork and dual rear air suspension, contributing significantly to its comfortable ride. Ergonomically, the Shadow comes with new ergonomic high-rise handlebars that are adjustable for varied riding positions and are wide enough to easily add accessories. The seat is described as a custom, high, soft-padded design, enhancing comfort during rides.

However, a frequently noted characteristic is its substantial weight, typically between 105 and 106 pounds including the dual batteries. This weight can make it challenging to lift, for example, onto a bike rack, and can affect its agility for some riders. Despite its size, one reviewer noted that the seat height (32-33 inches) is accessible even for shorter riders, such as someone 5'4". While the manufacturer states that video tutorials are "Coming Soon!", general eBike assembly videos suggest that assembling components like the front wheel, handlebars, and pedals should be straightforward for most users.

Performance Review

Furious Shadow Motor Performance (Peak W & Torque)

The Furious Shadow is powered by a robust 60V 1000W rear hub motor, which is custom "Adrenalized Motors" according to the manufacturer. It features a 28 Amp controller, allowing the motor to peak at approximately 1600 Watts. This power translates into impressive performance; user tests consistently highlight the bike's raw acceleration and strong hill-climbing capabilities. On a typical test hill where 750W eBikes take 22-25 seconds, the Shadow completed it in 20 seconds or less, showcasing its superior power. On flat ground, the Shadow can reach speeds of 30-34 mph, and even up to 38-40 mph on slight downhill sections, demonstrating that it doesn't limit assistance at the typical 28 mph. There are no notable complaints of throttle lag, and the power delivery feels smooth and strong.

Battery Life & Real-World Range Test

A standout feature of the Furious Shadow is its dual battery system, comprising two 60V 15Ah Samsung batteries, yielding a substantial total capacity of 1800 Watt-hours. The manufacturer advertises an impressive range of 80 to 120 miles per cycle. However, real-world user testing, specifically a throttle-only range test, reported nearly 50 miles of usable power before the battery indicator went blank. Even after the indicator was empty, the bike maintained usable power for several more miles, reaching a total of 48-50 miles in a rigorous throttle-only test. This significant difference between advertised and observed range is a critical point for potential buyers, especially those planning long, unassisted rides. The bike comes with a 3A charger; however, specific charging times for the dual 1800Wh battery system are not explicitly detailed by the manufacturer.

Ride Quality & Handling

The Furious Shadow offers a remarkably comfortable ride, largely attributed to its full dual suspension system. The combination of a Mozo hydraulic front suspension fork and dual rear air shocks effectively absorbs bumps and imperfections, making for a plush experience on various terrains. The 20" x 4" Kenda Krusade fat tires, despite their aggressive tread, are reported to be surprisingly quiet on pavement.

In terms of handling, the bike's considerable weight (105-106 lbs) is a notable factor. While the robust frame contributes to stability, this weight can make the bike feel less agile and more challenging to maneuver, particularly at low speeds or when attempting to lift it. User feedback suggests that the Shadow is designed more for "the pure enjoyment of riding a small little electric vehicle" rather than for riders seeking a traditional pedaling workout. The torque assist sensor engages quickly upon initial pedal pressure but does not continuously monitor torque like a true torque sensor. This means riders might find themselves relying more on the throttle for consistent power.

Brakes

The Furious Shadow is equipped with Zoom hydraulic disc brakes, featuring 180mm vented rotors and a motor cut-off for enhanced safety. Users report that the brakes provide adequate stopping power and seem to work effectively for the bike's speed and weight. The two-finger grip levers are noted for their good design and metal finish.

Drivetrain

The mechanical drivetrain consists of a Shimano Acera 7-speed derailleur with an 11-32T freewheel and a 52T Prowheel alloy crankset. While the gearing is described as "pretty good," riders noted that their legs spin quite quickly when attempting to pedal above 30 mph. The bike utilizes a Level 1 Torque Assist System, which means the motor activates quickly with initial pedal pressure, providing a smooth engagement. However, it does not continually adjust power output based on sustained pressure like a true torque sensor. This reinforces the perception that the bike is primarily designed for powered riding, with pedaling serving more as an assist or for compliance with eBike regulations rather than a primary mode of propulsion for exercise.
