Every model features a fully integrated 630 Wh battery housed inside the downtube, optimizing weight distribution for a more stable and natural ride.

The system is complemented by the XPro bottle-style battery.

Total Capacity:
630 Wh + 180 Wh (XPro Dual Discharge) = 810 Wh

Estimated Range:
150 km + 40 km (XPro Dual Discharge) = 190 km

INTEGRATED DISPLAY

A fully integrated top tube display provides all essential ride information at a glance, including speed, assistance mode, battery range, power output, cadence, rider torque and ANT+ connectivity.

iBUTTONS

The iButtons allow instant assistance mode changes directly from the handlebar. Because they are wired directly to the battery, they provide immediate response with zero delay. A clean, reliable system that keeps your focus on the ride.

AERO DESIGN & KAMM TAIL TUBE PROFILES

The new iRS1 delivers the perfect combination of power, range, lightweight construction and aerodynamic performance in a package designed for maximum efficiency and enhanced comfort over long distances.

The Kamm Tail tube profiles make the iRS1 a bike engineered for maximum aerodynamic efficiency. Their design optimizes airflow and reduces drag, making the most of every watt for consistent, efficient performance.
