2023 Surface 604 Twist

Surface 604 Twist E-Bike Summary

The 2023 Surface 604 Twist is a compact, folding electric fat bike that packs a punch with its powerful motor and feature-rich design. This e-bike is perfect for those who want a versatile ride for both urban commutes and off-road adventures. The Twist boasts a Bafang motor rated between 500 to 750 watts with an impressive 80 Nm of torque, providing a zippy and thrilling ride experience. The smaller wheel diameter enhances the motor’s mechanical advantage, making acceleration and braking more efficient.

One standout feature is the 180 mm hydraulic disc brakes with motor inhibitors, ensuring powerful and reliable stopping power. The Tektro brake levers also activate a blinking mode for the rear light, adding an extra layer of safety during night rides. The bike is equipped with a sturdy rear rack that’s integrated into the frame, capable of carrying panniers, a trunk bag, or even a child seat.

Despite its small appearance, the Twist is a heavyweight, clocking in at 63.8 pounds. This weight can be somewhat mitigated by removing the 8-pound battery, making it easier to handle when folded. The bike’s design includes a non-telescoping but sturdier stem, and a flared seat tube for increased frame stiffness, which is essential for handling its heft.

The Twist rolls on 20 x 4-inch fat tires that can be adjusted for various terrains. Lowering the tire pressure allows for better traction on soft surfaces like sand or snow, while higher pressure offers a smoother ride on paved roads. The plastic fenders are lightweight and durable, adding to the bike’s practicality without significantly increasing its weight.

Upgrades from the 2022 model include a stiffer Samix hollow spindle and a more robust square tubing, enhancing overall stability. The bike features a SRAM X5 10-speed drivetrain, providing a wide range of gears for tackling different inclines and terrains. Additionally, the reflective sidewall stripes on the tires improve visibility, and the integrated lights, including a bright 120-lumen front light, enhance safety during night rides.

The Twist’s folding mechanism is well-designed, with support arms to stabilize the bike when folded. However, securing the folded bike with a towel or a rubber bungee is recommended to prevent paint chipping. The bike’s cable management is decent, with most cables routed internally, reducing clutter and potential snags.

The 48V 14Ah battery is easily removable and locks securely into place, ensuring it won’t accidentally fall out during rides. Charging the battery is convenient with a well-placed charge port. The Twist’s battery capacity allows for extended rides, and the charger is compact and lightweight, though it charges at a modest 2 amps.

Riding the Twist is a pleasure, thanks to its stable fat tires and responsive torque-sensing pedal assist. The bike also includes a throttle for an extra boost, particularly useful on challenging terrains. The color LCD display provides comprehensive ride data, including battery percentage, speed, and trip distance, and features a USB port for charging devices.

In summary, the Surface 604 Twist is a well-rounded folding fat bike that combines power, durability, and convenience, making it an excellent choice for a variety of riders and riding conditions.
