Surface 604 Twist Review

Jun 2022

Price: $2399.00 | Model Year: 2022 | A folding fat tire electric bike with very approachable step-thru frame. Adjustable seat and handlebar height improve fit though it only comes in one size. Three colors including black, grey, and pink! Color LCD, powerful motor, clean wires and decals, quality 9-speed SRAM X5 drivetrain.

Observations
  • A folding fat tire electric bike with very approachable step-thru frame. Adjustable seat and handlebar height improve fit though it only comes in one size. Three colors including black, grey, and pink! Color LCD, powerful motor, clean wires and decals, quality 9-speed SRAM X5 drivetrain.

  • Good weight distribution of motor and battery pack, low and even across the frame. Ideal battery location, easy to access for removal and charging. Good lock and charge port positioning, high up on both sides of the main tube. Optional fast charger, trunk bag, pannier bags, suspension seat post, and more.

  • Free shipping and availability through 90+ dealers. Powerful hydraulic disc brakes with motor inhibitor and brake light blinking mode. High visibility reflective tires, premium integrated lights with side-cutout, and USB charging at the display. Torque sensing pedal assist is responsive and natural, trigger throttle overrides assist.

  • Kickstand mount is fairly close to left crank arm and could get kicked while pedaling. Torque sensor may surge or activate unintentionally on rough terrain. Weighs 59lbs due to large motor, fenders, lights, and integrated rack. No mechanism to keep the bike folded and no derailleur guard.
