Gain was designed to enhance your ride, not dominate it. The Enough Power and Enough Energy concepts result in an exceptionally lightweight, sporty, and fun-to-ride bike – a machine that heeds the call of the open road. Gain embraces your sweat and hard work and works in unison with your efforts to tick off the miles. System interfaces are modern, integrated, and sleek. There are no bulky components to reduce the riding experience, and distractions have been minimized, so it’s just you, Gain, and the enjoyable hours ahead.

Mode Button
Save space on your handlebar for a GPS if you wish, or ride without clutter. Gain’s control center is an attractive and discreet button on the top tube. With the simple iWoc ONE interface you can power the system on or off, check motor assist level and view the remaining battery charge. Colored LED lighting puts all the information you need right at your fingertips.

A smartphone- and smartwatch-compatible app enables deeper control of the iWoc system used by Gain. Ride tracking, GPS route uploading, and other functions are available from your mobile device, making Gain an even more valuable tool.

C.A.N. Integration
Gain doesn’t require a multitude of wires, ports or accessories. The CAN (Controller Area Network) bus port provides a single interface for charging, system diagnosis, or attaching the external backup battery.

Internal Battery
The battery is one of the most noticeable components of an eBike system, so every step has been taken to find the lightest, smallest, and most discreet unit. Gain’s Enough Energy concept provides you enough battery power, not more. It eliminates the need for a bulky, high-output battery that needs to be removed from the bike.

Drive System
The heart of Gain, the rear hub motor is the key to Gain’s Enough Power concept. The sophisticated drive system provides enough smooth and reliable assistance at levels designed to enhance your ride, not dominate it. And since the motor is at the hub, you’ll experience drag-free pedaling when Gain is not providing a push.
