Bosch Gen 5 Performance Line CX Upgrade: More Power, Smarter Control, and the Sleek New Kiox 400C Display

Big news in the world of e-bikes: the highly anticipated Bosch Gen 5 Performance Line CX motor upgrade has arrived — and it’s a true game-changer.

Whether you're conquering steep climbs or tackling technical trails, this latest update delivers unmatched power and performance. Now available at Cookson Cycles in Bury, Greater Manchester, this upgrade is set to redefine electric mountain biking.

Unleash Peak Performance: 100Nm Torque and 750W Output

The upgraded Bosch Performance Line CX Gen 5 (BDU384Y) motor now delivers:

100Nm of torque (up from 85Nm)
750W peak power output (up from 600W)
400% maximum assistance (up from 360%)

This performance boost means more torque for tough climbs, faster acceleration, and greater responsiveness on the trail. Perfect for demanding terrain, aggressive riding, or anyone who simply wants more out of their e-bike.

Even better, the upgrade is completely free and delivered via an over-the-air update through the Bosch Flow App, starting July 2025. Riders can also fine-tune torque, power, and assistance levels directly from the app.

Meet the Bosch Kiox 400C Display – Sleek, Smart, Integrated

Have you noticed a large cutout on the top tube of the latest Trek Rail and Haibike Hybe models? That’s for the all-new Kiox 400C display — Bosch’s most integrated and advanced e-bike screen yet.

Designed to sit flush in the top tube, the Kiox 400C creates a clean, modern cockpit and delivers real-time ride data with impressive clarity.

Key Features of the Kiox 400C Display:

Dynamic Display: Automatically highlights relevant data such as elevation during climbs or speed on descents
Customizable Interface: Adjust display settings to show exactly what you want
Automatic Brightness Adjustment: Ensures perfect visibility in all light conditions
USB-C Charging Port: Charge your phone, GoPro, or bike lights while you ride
Dual Control Options: Navigate via top tube buttons or an optional handlebar-mounted Mini Remote

The Kiox 400C will also be available as a standalone upgrade. Pricing and availability to be confirmed.

eMTB+ Mode: Adaptive Power Based on Terrain and Rider Input

Bosch has also introduced eMTB+ mode, offering adaptive support that adjusts in real-time to your pedaling input and terrain. With up to 400% motor assistance, it’s ideal for climbing steep trails or navigating technical sections with maximum control and efficiency.
