The Upgraded Bosch Kiox 400C: A Smarter, Sleeker Future for E-Bike Displays

The world of e-mountain biking is evolving fast, and Bosch continues to lead the charge with smart, intuitive tech. Their newest display upgrade — the Bosch Kiox 400C — is a major step forward in both design and functionality.
Built for riders who want durability, real-time data, and a clean cockpit, the Kiox 400C blends high-end engineering with modern usability.

In this post, we break down what’s new, what it improves, and why e-MTB riders are upgrading fast.

1. A Totally New Integration: Built Into Your Bike

Unlike traditional handlebar-mounted displays, the Kiox 400C sits integrated directly into the bike’s top tube.
This provides massive advantages:

• Zero handlebar clutter

• Lower risk of damage during crashes or tight trail navigating

• A premium, minimalist aesthetic

• Better protection against dirt, mud, and branches

For riders tackling rugged terrain, this change alone is worth the upgrade.

2. Brighter, Clearer, Smarter: The New 2.0” High-Visibility Screen

Bosch equipped the Kiox 400C with a super-bright 2-inch color display, boasting up to 1,000 nits of brightness — ideal for harsh sunlight or forest shade.

Highlights include:

• Auto-brightness via built-in light sensor

• High-contrast visuals for quick glances

• A dynamic layout that adjusts to show your most relevant ride data

• Glove-friendly touchscreen buttons

Whether you're checking speed, battery status, or navigation cues, everything stays crisp and easy to read.

3. Smart Power & USB-C Charging On The Go

One of the most requested features in modern e-bike displays? Charging output.

The Kiox 400C includes a USB-C port, letting you power:

• Smartphones

• Helmet or bar lights

• GPS trackers

• Action cameras

Since it draws power directly from your main e-bike battery, there’s no separate charging needed for the display itself.

4. Smarter Navigation With the Bosch Flow App

Through the Bosch eBike Flow app, riders can customise the screen with up to 30 different layout combinations, pulling in:

• Turn-by-turn navigation

• Elevation profiles

• Cadence and power output

• Ride analytics

• Fitness summaries

Launch a route in the app and the 400C takes over — giving you clean, clear, simplified directions so you keep your eyes on the trail.

Fully Compatible With Bosch’s Mini Remote

Although the 400C features built-in controls, many riders pair it with the Bosch Mini Remote for:

• Bar-mounted control

• Hands-on adjustments while riding

• Quick mode switching

• Better ergonomics for technical trail riding

The combination of the top-tube display + remote is one of the cleanest cockpits in the eMTB world.

6. Built for Real-World Trail Abuse

Bosch designed the Kiox 400C specifically for eMTB riders, so durability was a top priority:

• IP55 dust/water protection

• Impact-resistant glass

• Recessed mounting for frame-level protection

• Rugged construction for rock strikes and crashes

7. Part of Bosch’s Bigger Performance Upgrade

The Kiox 400C wasn’t released in isolation — it pairs perfectly with Bosch’s latest motor firmware improvements, including:

• Up to 100 Nm of torque

• Up to 400% support in eMTB mode

• New “eMTB+” setting for aggressive trail power

• Improved responsiveness and pedal feel

Together, they create one of the most capable e-MTB ecosystems available today.

8. Compatibility Notes You Should Know

Before ordering, check:

• Your frame must support the top-tube cut-out design

• Not compatible with older Bosch LED Remotes or some Purion units

• Not suitable for speed-pedelec (45 km/h) models
