Description
Product overview
The Ewheel QS-S4 36-72V (6 pin) display with index throttle is a control screen and throttle control unit designed to drive and monitor an electric mobility system. It enables essential information to be displayed and assistance/power to be managed from the driver's seat, with a direct grip thanks to the integrated index trigger.
User benefits
This display for electric bikes and soft mobility devices simplifies the management of daily commuting: quick reading of information on the screen, immediate access to controls, and modulation of acceleration via the index trigger for more intuitive control. It's a practical solution for replacing a faulty screen or upgrading a 6-pin compatible control station.
Technical specifications

Recommended uses
This QS-S4 display is recommended for replacement of a control screen or installation on a light electric vehicle requiring a 36-72V-compatible display with 6-pin connectors, and an index throttle. Suitable for configurations where you want to centralize display and control at the driver's station (handlebars), particularly on electric mobility-oriented set-ups.
Compatibility
Electrical compatibility: 36V to 72V systems.
Connector compatibility: only with harnesses/controllers using a compatible 6-pin connection.
To avoid connection errors, we recommend that you check the pinout correspondence with the exact type of connector on the controller/beam side before ordering.
Expert advice
Before installation, switch off the power supply and disconnect the battery. Check the nominal voltage of your battery (36V, 48V, 60V or 72V) and make sure that the 6-pin connector is strictly identical (format + pinout), as a similar connector may have different wiring for different controllers. When replacing, inspect the condition of the harness (oxidation, bent pins, play in the connector) to avoid false contacts. After installation, perform a stationary test (display, controls, acceleration) before riding, and secure the wiring to the handlebars to limit mechanical stress and improve assembly longevity.
