A large, high-contrast computer for riders who want turning guidance and e-bike connectivity without a steep price or complicated interface.

Overview

The ROX 4.0 is built around an extra-large, high-contrast 2.4" transflective display designed to stay readable in every light condition, controlled with simple 3-button operation.

It's equipped with GPS and GLONASS positioning, turning guidance with U-turn alerts and Back to Start arrow navigation, a barometric altimeter, ambient light sensor, and e-bike connectivity that shows assist mode, battery status and range on compatible systems (current Shimano Steps, Brose, Panasonic, BMZ, Sachs and TQ motors). ANT+ and Bluetooth handle sensor pairing and syncing via the Sigma Ride app, and it's rated IPX7 for water resistance with up to 25 hours of battery life.

It suits riders who want an easy-to-read, straightforward computer with genuine navigation and e-bike support, at a genuinely accessible price point.

Why You'll Like It

Large, high-contrast display
Extra-large numbers and strong contrast keep the screen easy to read in bright sun or low light alike.

Turning guidance with U-turn alerts
Reliable navigation prompts with a clear alert when you're heading the wrong way, plus Back to Start arrow navigation.

E-bike ready
Connects to compatible e-bike systems to show assist mode, battery status and range directly on the display.

Simple 3-button operation
No touchscreen to manage, with an interface most riders pick up quickly.

Six adjustable training views
Individually configurable sport profiles and training pages, so the display matches how you actually ride.

Who Is It For?

The ROX 4.0 suits riders across Indian cities who want an easy-to-read, no-fuss computer with genuine turning guidance and e-bike compatibility, at a value price point.

It's also a good fit for e-bike riders specifically, since the assist mode and battery status display is a genuinely useful feature not every budget computer offers.

Good to Know

Turn-by-turn directions can occasionally lag slightly behind your position — the U-turn alert is the more dependable navigation cue if you've gone off track. Data syncs to the Sigma Ride app over Bluetooth after your ride, and the display stores up to 100 hours of ride history.
