The Surface 604 Colt can be more than just the best electric beach cruiser bike, it also serves as an excellent commuter vehicle, and dabbles as a mountain bike. Torque-sensing offers power for sporty moments, while built-in features like chain guard rear rack fenders front rear, LED lights and bell are great to have as a commuter. As you read and research more about this bike, you will see why some have it as the best electric bike for the beach.

Why We Like It – Surface 604 Colt

The Surface 604 Colt is comfortable, durable, and well-built with commuters in mind, features like rear LED lights front LED lights, and a rear rack, in addition to a great battery and 20mph top speed.

  • Speeds around at 20mph
  • Multiple features that favor commuters
  • Smart torque sensor matches your pedaling
  • A bit pricey

Durability & Build Quality

The Surface 604 Colt doesn’t hold back on durability and quality. SR Suntour NCX suspension can be added to the seat post. The tapered headtube frame type has internal cables to prevent damage, and it has a Satori UP2+ adjustable stem. And its suspension fork is an SR Suntour XCT 80mm travel, 9mm quick release axle.

It’s almost entirely made of 6061 aluminum alloy, which is very strong and lightweight. Dimensions do change depending on size; small medium has a slightly small seat tube of 444.5mm, while medium large is 495mm.

On that note, if you’d like more ebikes made of aluminum alloy, you’ll want to read our reviews of the Trek Verve, Schwinn Voyageur, and the Tomasar Power electric bike. Alternatively, if you want a model made from steel, then you’ll want to check out the NAKTO Spark e-bike.

Performance (Speed & Acceleration)

The Surface 604 Colt Electric Bikes are fast enough to commute back and forth. Looking from above, 20mph doesn’t sound like much, but remember: you aren’t pumping carbon dioxide into the air. The 500W hub motor has some juicy features such as torque sensing. It adds power to your pedaling, seamlessly, based on your pedaling. The Shimano Alivio 9-speed transmission offers a nice variety of speeds. The IZIP E3 is only a few miles ahead at 28mph. A more adventurous bike for the trails and hills can be found in the Speedrid folding ebike review.

Range & Battery

With the Surface 604 Colt’s Samsung lithium-ion battery, you can easily get 35 miles on a single charge. Drive modes like its pedal assist levels lessen and raise that number. The Juiced City Scrambler can go well over 40 miles on a single charge.

Safety Features

The Surface 604 Colt Electric Bike is designed to be safe, naturally, but it also incorporates rear and front headlights. There’s also a trigger power output limit based on the level of assist. You need to also look at the Surface 604 rook review for another commuting bike.


Is the Surface 604 Colt worth its $2000 asking price? Taking into consideration of our Colt Electric Bike review, we would say: absolutely. It’s a bit pricey, yes, but it’s offering most if not all the features commuters look for in an electric bike, like headlights, a rack area, and even USB for mobile charging. That’s way more than what the $2750 Raleigh Retroglide IE offers.

Surface 604 Colt Wrap Up

Despite its somewhat expensive pricing, the Surface 604 Colt is an amazing workhorse. It’s built, from the ground up, to dabble in sporty behavior with its torque sensing, but gives 100% of its attention to commuters. Traveling 20mph on a 35-mile-per-charge battery is nothing to scoff at.
