Overview

The e-B-9 NH Mk II is the electric evolution of the original B-9 NH Urban Stealth. The Mk II develops the original B-9 NH concept into a lightweight electric bicycle while retaining its distinctive geometry, minimal appearance and riding character.

Electric assistance is provided by the Zehus HALOS all-in-one rear hub system, allowing the original frame and its clean visual identity to remain essentially unchanged.

The first completed e-B-9 NH Mk II is based on the camouflage B-9 NH bicycle.

Electric Integration

The Zehus HALOS system integrates the motor, battery and control electronics within the rear hub, eliminating the need for an external battery or conventional frame-mounted drive unit.

Its compact architecture fits naturally with the original B-9 NH concept, retaining the clean carbon frame, Gates Carbon Drive and minimalist appearance.

The Mk II realises an electric version of the B-9 NH that had already been considered during the earlier development of the project.
