https://electricbikereview.com/surface-604/rook/ The Surface 604 Rook Review is an approachable step-through that comes in two frame sizes and two colors! This hybrid electric bike offers fenders, deluxe rear rack, integrated lights, and two battery options for long range. Relaxed handlebar, adjustable angle stem, high volume 27.5" tires, and ergonomic touch points offer comfort. Unique combination of torque sensing pedal assist with trigger throttle that overrides for added power. Settings menu provides adjustable top speed, adjustable assist levels, and adjustable brightness. Two integrated USB charging ports (one on the display and one on the battery pack) to maintain portable electronics. Excellent stopping power thanks to Tektro Auriga hydraulic disc brakes with large 180mm rotors and motor inhibitors and brake blinking activation. Mid-level derailleur and nine-speed cassette provides plenty of options for urban riding. Excellent safety features including bright headlight with side windows that is mounted up high on the stem, and reflective tires. The battery charge port is next to the left crank arm which could make it vulnerable. No slap guard on the right chain stay, pedal assist can activate unexpectedly if the chain is bouncing excessively. Limited 11-32 tooth cassette vs. 34 or 42 on some comparable models. Price has risen a bit in recent years, the optional battery upgrade sticks out on the left side a bit vs. being symmetrical.
