Intuitive Design and Exceptional Visibility
eTrimm's screen layout is designed with both usability and aesthetics in mind. The clear contrast and typography, which consider visual hierarchy, ensure optimal visibility even under strong sunlight. Additionally, the modular data fields, distinguished by color and size, are arranged on a consistent grid system, allowing users to intuitively learn the location of information. This systematic structure also makes the customization process of rearranging the screen as the user desires easy and convenient.

Intelligent light control

eTrimm's intelligent lighting control automatically selects the optimal light mode for your riding environment with a simple initial setup. When linked with the LightSKIN U1, you can experience even more extended smart features..
eTrimm Navigation


eTrimm Navigation syncs with your smartphone to provide real-time route guidance.
It also integrates route data into the e-bike's system to optimize riding functions like battery management and motor output. This navigation feature serves as the central hub for all smartphone connectivity.
eTrimm Safe Music Riding

Ride with Maximum Safety, and All the Fun
Statistics show that 20-30% of cyclists listen to music while riding, and this percentage is even higher among e-bike users. However, operating a smartphone directly is a leading cause of accidents. The eTrimm Safe Music Riding feature allows you to fully control key functions of your music app—such as play/pause, next/previous song, playlist scrolling, and repeat—with the eTrimm controller on your handlebar, so you never have to take your eyes off the road. This makes your ride safer and more enjoyable.

Walking & Power off

Smart while riding, Convenient when stopped
eTrimm combines 'Walking Mode' and 'Power Off' functions into a single screen. When you press and hold the top button, Walking Mode is activated, gently moving the bike at walking speed. The bottom button provides a 'One-Touch Power Off' feature, turning the power off with just a single press. This method is more intuitive than the common practice of pressing and holding for three or more seconds, allowing even first-time users to instantly shut down the system.

No matter which motor you chose, the user experience is always one.
eTrimm will continue to expand its compatibility with major motor manufacturers, including Shimano, Ananda, Bafang, and Mahle. This means that regardless of which motor system your company (the bicycle manufacturer) adopts, you can provide a consistent and unified user interface (UI) across your entire bicycle lineup. As a result, you can unify a fragmented user experience (UX) to strengthen your brand identity and establish a powerful foundation for increasing future brand value.
