The Surface 604 Shred e-bike, priced at $2,599 USD, offers a versatile riding experience reminiscent of an SUV, suitable for both urban and trail environments. With its two available frame sizes, the Shred is designed to accommodate a variety of riders, providing comfort and control through its upright geometry and adjustable handlebars. The bike is powered by a Bafang 500-watt planetary geared hub motor, renowned for its smooth and quiet operation. Unlike many e-bikes that use cadence sensors, the Shred features a torque-sensing pedal-assist system, which delivers a more natural and responsive ride, encouraging active pedaling.

Safety and control are paramount on the Shred, thanks to its hydraulic disc brakes with motor inhibitors, ensuring the motor cuts off immediately when braking. The bike is equipped with boost hub spacing and thicker spokes, enhancing durability and stability on rough terrains. The inclusion of plus-sized 27.5″ x 2.8″ tires provides excellent traction and comfort, especially important for a hardtail bike lacking rear suspension.

The Shred’s stock configuration includes a steel SR Suntour spring fork, offering basic adjustability with lockout and preload features. However, riders seeking enhanced performance can opt for the Wren inverted air fork, a $799 upgrade that offers customizable air pressure settings and improved suspension dynamics. Both forks boast 110mm of travel, suitable for cross-country riding.

Utility is a standout feature of the Shred. It comes with pre-installed rear rack bosses and wiring for an optional commuter package, which includes a rack and integrated lights powered by the main battery. The e-bike also includes a built-in headlight, adding to its practicality for daily use.

The drivetrain comprises a narrow-wide 38T chainring and a 9-speed Shimano Alivio cassette, providing reliable and efficient power transmission. Despite the lack of a chain slap guard, the satin black frame with glossy branding maintains a sleek and professional appearance. The bike also features quick disconnects for the motor and torque sensor cables, facilitating easy maintenance.

Surface 604 offers a high-capacity 20 Ah battery as an optional upgrade, extending range and usability for long rides. The battery, weighing 10 pounds, includes a USB charging port for added convenience. Riders can also invest in a four-amp charger to speed up charging times.

The Shred’s cockpit is equipped with adjustable-reach brake levers, a trigger throttle, and a user-friendly color display that offers detailed metrics, including speed, power output, and battery percentage. The display also allows riders to adjust assist levels and access advanced settings, including speed limit customization and unit preferences.

Overall, the Surface 604 Shred e-bike blends practicality with performance, catering to both commuters and adventure seekers. Its thoughtful design and optional upgrades make it a versatile choice for those who want a reliable and stylish electric bike.
