Surface 604 Quad E-Bike: Summary

Welcome to the world of the Surface 604 Quad, an electrifying ride that promises a unique blend of style, strength, and versatility. Inspired by the iconic 1980s quadangle bicycles, the Quad’s frame design features an eye-catching crisscross pattern that enhances its visual appeal while maintaining the bike’s structural integrity. This distinctive frame keeps the stand-over height lower compared to traditional step-through models, offering a stylish yet stiff ride that distinguishes itself from the more conventional step-through or midstep designs.

Surface 604 has ingeniously reimagined their successful Shred model to birth the Quad. Both models share a lot of components, proving that they hit the nail on the head with the Shred. The Quad is all about style and function, adorned in brushed aluminum alloy with glossy branding highlights that subtly scream sophistication. While a slap guard is missing, the robust design minimizes the visibility of chain grease, and a simple clear tape can easily resolve any potential nicking issues.

With two frame sizes, medium-large and small-medium, the Quad caters to a variety of riders. At 5’9″ and 135 pounds, the reviewer finds the medium-large a comfortable fit. Priced at $2,599 with a standard 672-watt-hour battery pack, and $2,999 for the 960-watt-hour upgrade, the Quad offers options based on how far you want to travel or your weight. For added convenience, the bike includes bottle cage bosses and attachment points for a rear rack, making it possible to carry essentials or even a child seat for the ultimate family adventure.

The Quad is built for both trail enthusiasts and urban commuters, equipped with Maxxis Rekon tires that boast a 27.5 x 2.8 size for superior traction and stability. These plus-size tires, along with a 17 to 35 psi range, provide a cushioned, float-like ride that’s a joy on various terrains. While the tires enhance the ride, they aren’t reflective like some Surface 604 models, adding to the Quad’s clean, brushed aluminum look.

A 100mm travel suspension fork with 15mm thru-axle ensures a sturdy setup, perfect for off-road adventures. The Quad’s motor, a Bafang 500-watt, 750-watt peak planetary geared hub, offers 65 Nm of torque. Its torque sensor provides a dynamic, responsive ride, making it a true trail contender that can hold its own alongside mid-drive motors.

For those looking for versatility, the Quad can transform from a Class 2 e-bike with throttle to a Class 1 bike by removing the throttle, making it trail-legal. This flexibility is matched with a drivetrain featuring a 38-tooth chainring and an 11-36 tooth cassette, ensuring a smooth ride no matter the terrain.

As a Canadian product, the Quad boasts water-resistant components, making it well-suited for wet climates. The lightweight hollow spindle and narrow-wide chainring keep the ride smooth and reliable. With a weight of approximately 57.5 pounds, the bike balances strength and maneuverability, although it leans slightly heavier compared to similar models.

Surface 604’s dedication to quality extends to the Quad’s safety features, including 180mm disc brakes and motor inhibitors in the brake levers, ensuring safe stopping power. The thoughtful design choices continue with an adjustable display for easy visibility, dual USB charging ports, and the ability to charge devices directly from the bike’s battery.

While the Quad is a robust, direct-to-consumer product, buyers should be prepared for minor assembly upon arrival. This minor inconvenience is a small price to pay for the Quad’s affordability and impressive feature set. Surface 604 also offers extensive support, with forums for direct feedback from other users.

In summary, the Surface 604 Quad is more than just an e-bike; it’s a blend of nostalgia and modern engineering, offering a versatile ride that’s as at home on city streets as it is on rugged trails. With its stylish design, thoughtful features, and robust build, the Quad promises to deliver both fun and functionality, ensuring every ride is an adventure.
