Passion, Performance, and Delivered to your Doorstep

Headquartered in Vancouver, Canada, Surface 604 is passionate about electric bikes. They are on a mission to change people’s perceptions about what’s possible on an e-bike and to get more people riding more often.

Surface 604 e-bikes are designed in Canada by riders for riders. Their team has well over a century of road and mountain biking experience and has seen trends and gimmicks come and go. So when it comes time to spec our bikes, they go straight for a powerful motor and some of the biggest, most respected names in the industry – SRAM, FSA, Tektro, Kenda, Bafang and SR Suntour – and assemble a component sheet combining uncompromising performance with value.

Agile Urban Commuter

The Yunbike C1 has been specifically designed and built for the modern city cyclist. The aluminum frame and lithium ion battery mean that unlike its heavier counterparts, the C1 weighs just 35lbs; perfect for carrying in and out of the apartment and heading off to work.

Smart System with Mobile App

Through a built-in smart system that communicates directly with an app on your mobile device, tracking your speed, distance ridden, and battery life is at your fingertips. The handlebar display and throttle also contains a USB port that charges your mobile device as you pedal to your destination.

Removable Battery Pack with Power Bank

The removable battery includes a convenient USB power bank with enough energy for 22 individual device charges.

Discrete Battery Placement and Integrated LED Lighting System

The discrete placement of the battery at the rear keeps the design sleek and stylish, as well as providing a built-in rear light. Paired with a powerful front light, the integrated LED system means you’re set for riding into the night.

Classic and Step-Through Frame Designs in Funky Colors

The Yunbike C1 electric commuter bike is available in both classic and step-through frame designs built to appeal to any type of rider. The step-through bikes come in three colors: bright red, mint green and white with pink trim. The classic bikes are available in one color – metallic graphite.

Accessories – Racks and Fenders

For many of us, urban commuting means riding in inclement weather and carrying gear. We’ve designed custom aluminum racks and fenders allowing you to commute comfortably in all conditions.
