Alright, let’s take a closer look at the Surface 604 Rook.
The Surface 604 Rook is a well equipped step-thru eCommuter bike with impressive features and components for the price of $1,999.
The Rook frame has a step-thru design to make getting on and off the bike easier compared to throwing your leg over the top tube of a traditional triangle frame design.
The lowest point of the step-thru area is about 19″ above the ground.
6061 aluminum hydroformed tubing is used to shape the frame to create features like the step-thru area and integrate the battery in the downtube.
There are 2 frame sizes offered:
S/M with a 17.5″ frame for riders in height: 5′-2″ to 5′-7″
M/L with a 19.5″ frame for riders in height: 5′-8″ to 6′-6″
In addition to the Black/White color in this testing there is also a White frame color option.
Here is a closer look at the headtube area with the connection of the top and down tubes.
There is substantial weld area for a sold looking connection at this high stress area of the frame.
The top tube has a trapezoidal look to it and the down tube is somewhat square with a rounded lower profile.
These tube shapes add a bit of functional style to the Rook’s look with the battery integrated into the downtube.
There is internal cable routing through underside of the downtube for cable protection and a clean look.
Here is a closer look at the weld details of the seat tube, seat stays, and rear rack attachment points.
Also in this view is the seat post quick release for quick adjustments of the seat height.
There are 2 battery options available for the Rook. The stock battery is a 48V 10.4ah (500Wh) lithium with Samsung 18650 cells.
There is an upgrade option for an extended range battery that is a 48V 14ah (672WH) and it uses the same Samsung 18650 cells. This upgrade adds $200 to the $1,999 base price. This is the battery being used in this testing & review.
The downtube location of the battery is ideal for the balance and handling of the bike because it is low and centered. It also has a clean look that blends in well with the overall look of the bike.
The Surface 604 ebikes are designed in Canada.
A highlight of the Rook frame is the rear rack that is welded to the frame for a sturdy cargo carrier.
The main structure has large aluminum tubing while the smaller tubes are built for the attachment of bags and panniers.
Not only does the welded connection give extra strength and rigidity to the rack but it also is zero maintenance in use, with no bolts to work loose.
Here is a closer look at the smaller tubing to accommodate a range of baskets, bags, and pannier attachments.
A feature highlight for a bike in this price range is the Samox crankset with a 42 tooth chainring. It features a hollow axle design for lower weight.
The full coverage chain guard is a nice stock accessory for keeping your pant legs clean and out of the chainring.
The Wellgo pedals have a wide aluminum platform and a rubber edge for extra grip. There are reflectors on both ends of the pedals.
A Shimano Alivio derailleur shifts through the 9 speed cogset that has a 11 tooth to 34 tooth range.
Providing the pedal assist and throttle up to 20 mph is the 500 watt (750 watt peak power) Bafang geared rear hub motor. The Rook is a Class 2 electric bike.
In this view you can see that the motor is fairly compact in size and blends in well with the size of the cogset and disc brake rotor.
This is the left side view of the Bafang motor with the 180mm rear disc brake rotor and Tektro Auriga hydraulic disc brake caliper.
A feature highlight of all Surface 604 eBikes is that they use a torque sensor system for the pedal assist.
The Axendo LED headlight is powered by the eBike battery so you don’t have to worry about separate batteries for the light.
The rear LED light is also powered by the main battery and is attached to the rear of the rack.
Full coverage plastic fenders are found front and rear.
Here is a look at the rear fender and the rear rack.
Rounding out the stock accessory package is the kickstand that is bolted to the left side of the frame. The length is adjustable so that you can adjust the tilt of the bike when it is parked.

Review Note: Each company pays a fee for a review on Electric Bike Report because of the considerable amount of time that it takes to provide an in-depth review of each eBike. A lot of time is spent on the full range test with distance & elevation profile, the wide variety of detailed pictures, in-depth video, and the write up with the specifications, ride characteristics, pros, cons, and overall thoughts. The reviews on Electric Bike Report are focused on providing you with a detailed “virtual” look at each eBike to help you determine if it is the eBike for you.
