Overview: Surface 604 2020 Rook

The Surface 604 2020 Rook is an electric bike with an upright or upright relaxed body position suitable for neighborhood, urban, and commuting use. This electric bike belongs to the Throttle on Demand (Class 2) category, which means it can be powered by both pedal assist and a throttle. Priced at $1,999, the Surface 604 2020 Rook comes with a 1-year comprehensive warranty and a 3-year frame warranty. This electric bike is available in the United States and Canada and was released in 2020.

• The Surface 604 2020 Rook is a feature-rich and approachable step-through city bike available in two frame sizes and two colors, suitable for neighborhood and urban commuting.
• The bike comes standard with a rear rack, fenders, and Spanninga lights, providing convenience and safety.
• The rare combination of a torque sensor with a rear hub motor delivers a smooth and responsive riding experience, and the Suntour suspension fork, Selle Royale gel saddle, ergonomic grips, and upright relaxed riding position provide a high level of comfort.
• The Tektro Auriga hydraulic disc brakes with 180mm rotors and dual-piston calipers ensure solid stopping power, while the Shimano Alivio groupset provides a smooth shifting experience.
• The Surface 604 2020 Rook has a large dealer network in both the US and Canada for test rides and support down the road.
• However, there are a few drawbacks to note, such as the display being dim in direct sunlight, no puncture protection or reflective sidewall striping on the tires, the charge port being located next to the right crank arm, and no slap guard on the right chainstay, leaving the paint vulnerable to scratches when going over bumps.
