"Smart-Hub" Display Module for TWINNER E-Bikes: Smart in the Fast Lane

The Twinner e-bike sets new standards—as does its customized 3.5-inch display. Fully integrated into the frame, the display functions not only as a touchscreen to control a wide range of features, but also as a rear-view camera. Full control is guaranteed in bright sunlight and heavy rain alike. Furthermore, to make assembly as straightforward as possible, an all-in-one turnkey solution was needed: display, embedded software, cabling, and housing.

That is why we developed the complete Smart Hub solution for TWINNER, tailored precisely to meet these demanding requirements.

The Customized Smart-Hub Solution for TWINNER

The desired applications and features require a TFT display integrated directly into the carbon monocoque handlebar. Our experts house the electronics in a durable plastic enclosure, reliably protecting them from dirt and moisture. In parallel, we are developing the smart embedded software—a technology that enables seamless control across the entire e-bike.Following intensive testing, the Smart Hub is delivered to the customer for further evaluations—some conducted under extreme conditions. The goal is simple: users must be able to operate the display in any weather, with or without gloves.Technical Display Data
