The Surface 604 Colt 500W 48V suspension e-bike is designed for cruisers and commuters seeking comfort.

The Colt features a powerful 500w motor with a 48v battery and comes fully-loaded with every feature needed to make riding effortless including a suspension fork, adjustable stem, built-in rear rack, front and rear fenders, and LED lights.

You can achieve a top speed of 20 mph on this bike, reaching a distance of 45 miles on a single charge.

Why BUY This Electric Bike:

1.  Comfortable Cruiser Bike With Adjustable Stem

The Colt e-assist bicycles have been designed with comfort in mind.  We’ve 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.

2. Built-in Rear Rack

The heavy-duty built-in rear rack easily holds all types of pannier bags with a max load of 100 lbs (45kg)

3. Fenders and Chain guard

The Colt 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.

4. Suspension Fork

All roads are not created equal, and the Colt includes an SR Suntour XCT Suspension fork, absorbing even the bumpiest conditions for a smooth, easy ride.

5. Torque Sensor and Throttle on Demand

With a torque sensor and throttle on demand, the Colt 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.

6. Discrete Battery Placement with Power Bank

Unlike other electric assist bikes with bulky batteries taking up space on rear racks, the battery for the Colt 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.

7. LED Front and Rear Lights

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.
