Surface 604 Colt Summary

Surface 604 Colt, a versatile e-bike that blends the best of mountain biking heritage with urban convenience. The Colt is a step-through version of the Rook, designed for those who prefer a more approachable and slightly beefier ride. Weighing in at around 62 pounds (compared to the Rook’s 58 pounds), this bike is built for both comfort and performance, making it a great choice for a variety of riders.

The Colt comes in two frame sizes: medium-large and small-medium. It offers a higher standover height and a bit more stiffness, making it easier to lift and maneuver. If you’re taller, you’ll have no problem stepping over the frame. The bike features a built-in rear rack, perfect for those who tend to bonk their shins on trunk bags or other gear.

One of the standout features of the Colt is its color options—or lack thereof. Unlike the Rook, which comes in both black and white, the Colt is available only in black. This gives it a sleek, uniform appearance that’s complemented by reflective sidewalls on the tires and a high-mounted headlight for increased visibility.

Surface 604, a Canadian company, designed the Colt with a hybrid feel for around-town riding. It retains its mountain biking roots with a suspension fork that includes a lockout feature and preload adjustment. If you want to go the extra mile for comfort, you can swap the rigid seat post for a suspension seat post, although this will raise the minimum saddle height slightly.

The Colt’s saddle has been upgraded to a Selle Royal Essenza Plus, offering a plush, comfortable ride. The handlebars are ergonomic and longer than those found on typical mountain bikes, paired with an adjustable angle stem that allows for a more upright or aggressive riding position, depending on your preference.

The tires are 27.5″ x 2.4″, providing a smooth ride over bumps and obstacles with their lower attack angle and larger contact patch. These tires also feature puncture resistance, ensuring durability and reliability on various terrains. The bike’s hollow spindle and hydraulic disc brakes add to its performance, offering weight savings, stiffness, and excellent braking power.

The Colt’s drivetrain includes a Shimano Alivio 9-speed cassette, offering a range of gearing options for different riding conditions. The bike is powered by a Bafang geared hub motor with 500 to 750 watts of power and 45Nm of torque, making it both powerful and efficient. The motor is controlled by a TMM4 torque sensor, providing a more dynamic and responsive riding experience compared to cadence sensors.

The battery is another highlight, with two options available: a standard 672Wh battery and an upgraded 960Wh battery. Both options include a USB charging port, allowing you to charge your devices on the go. The battery is easy to remove and lock, ensuring convenience and security.

The Colt’s display is user-friendly, offering a range of settings and readouts, including battery percentage, speed, trip distance, and more. The bike also features walk mode, making it easier to maneuver in tight spaces or technical terrain.

In summary, the Surface 604 Colt is a robust, versatile e-bike that combines comfort, performance, and utility. Whether you’re commuting, running errands, or enjoying a leisurely ride, the Colt is equipped to handle it all with style and reliability. So, gear up and get ready to hit the road with the Colt!
