Description

 Introducing the Surface 604 Big Sky, a cruiser electric bike that blends style, performance, and affordability. With its matte gray finish accented by bold orange and blue details, this bike stands out on any ride. The Big Sky boasts a rigid aluminum alloy frame and a comfortable high step design with swept-back handlebars, making this model ideal for riders who appreciate a larger and more spacious frame than the comparable Sunny Day model.

Equipped with a powerful 500W nominal, 750W peak hub motor, this Class 2 e-bike can be unlocked for Class 3 speeds. The torque-sensing pedal assist ensures a natural and responsive riding experience, seamlessly amplifying your efforts. The trigger throttle, coupled with a Shimano 9-speed drivetrain, provides versatility for various terrains.

Navigating urban environments is a breeze with Tektro hydraulic disc brakes featuring motor inhibitors for instant power cutoff, enhancing safety. The bike's weight is thoughtfully distributed for optimal handling and stability, aided by 27.5x2.4-inch high-volume tires that add comfort and efficiency, smoothing over cracks and bumps.

The Big Sky comes standard with a plush saddle, an ergonomic riding position, and reflective sidewall stripes on the tires for added visibility. The battery, available in multiple capacities, is easily removable for charging or storage, with a handy USB port on top for your devices.

With thoughtful design elements like pre-wired lighting, fender mounts, and a rear rack option, the Big Sky is versatile for commuting or leisure rides. Surface 604's commitment to quality is evident in the construction, and the bike comes with a comprehensive one-year warranty and three years on the frame.

Explore your surroundings effortlessly with the Surface 604 Big Sky – a cruiser e-bike that redefines the joy of cycling.
