The Rook’s e-assist bicycles have been designed with comfort in mind. Surface 604 have combined the power of a 500w+ motor with a light, versatile frame to create a bike that is well-equipped for riders looking for some extra momentum to get them around quickly and easily. The bike features an adjustable stem that can be fine-tuned on the fly for individual riding styles without the need for tools.

The heavy-duty built-in rear rack easily holds all types of pannier bags with a max load of 100 lbs (45 kg). The Rook is built for the year-round commuter, and comes direct from the factory with front and rear fenders and a chain guard, keeping water, mud and grease off clothes and ensuring riders arrive fresh and mess-free.

All roads are not created equal, and the Rook includes a SR Suntour XCT Suspension fork, absorbing even the bumpiest conditions for a smooth, easy ride. With a torque sensor and throttle on demand, the Rook is great for those travelling longer distances, on a variety of grades, and needing a little extra stamina to make it to work while still be able to enjoy the ride.

Unlike other electric assist bikes with bulky batteries taking up space on rear racks, the battery for the Rook placed discreetly in the down tube, also assisting with better weight distribution. As an added bonus, the battery also features a USB plug for charging mobile devices on the go.

The powerful front and rear LED lights that feed off the main battery mean never having to worry about charging or replacing batteries at the end of a long day. SURFACE 604’s line of ‘ROOK’ is available available in 2 sizes: S/M (17.5″), M/L (19″) frame in 2 colors: grey or white.

E-Bikes are street legal, just like bicycles, and do not require driver’s license, insurance or registration. Best of all, E-Bikes do not require gas either! Just charge it and go!
