https://electricbikereview.com/surface-604/2018-rook/ The Surface 604 Rook is a relatively affordable, well-supported, feature packed electric bike with plastic fenders, a chain cover, integrated LED Lights, and an adjustable suspension fork. With shorter reach and an adjustable-angle stem, this ebike feels pretty upright and relaxed, the gel saddle and basic ergonomic grips provide a lot of comfort, along with the fatter tires. Available in two frame sizes and two beautiful color schemes (satin white or black), pedal assist feels smooth and natural because it uses a torque sensor, satisfying trigger throttle, hydraulic disc brakes with motor inhibitors. The tires are pretty basic (no puncture protection or reflective stripes), the plastic fenders are durable but rattle more than steel or aluminum, sturdy rack with pannier rods and bungee loop, great kickstand, optional suspension seat post.
