Description

Overview

The Viketory 29x2.4 rear wheel with an integrated 250W (42 Nm) ROKTAR/ZEPHIR motor is a motorized rear wheel designed to repair or motorize the drivetrain of an e-bike equipped with this type of motor. It combines the rear rim and hub motor into a single unit, simplifying replacement and restoring functional electric assistance.

Benefits for the User

This “rim + motor” assembly saves time during replacement by eliminating the need to separately source a compatible hub motor and install it onto an existing wheel. The rated torque of 42 Nm contributes to more effective assistance during acceleration and on challenging terrain, while maintaining a motor power of 250W suitable for e-bike use.

Technical Specifications

Rear wheel with a 29-inch rim, designed for a 2.4-inch tire. Integrated rear hub motor with 250W power, delivering 42 Nm of torque. This configuration corresponds to a complete rear motorized wheel designed for ROKTAR/ZEPHIR systems.

Recommended Uses

Ideal for replacing a damaged or worn-out motorized rear wheel as part of maintenance or repair work on an e-bike. Suitable for users looking for a complete solution (rear rim + motor) to restore electric assist and get back on the road with a ready-to-install kit.

Known Compatibilities

Compatible with motorizations/systems identified as ROKTAR/ZEPHIR, as specified in the product description.

Expert Advice

Before ordering, carefully verify that your bike is equipped with a ROKTAR/ZEPHIR system, and check that the wheel size (29") and tire width (2.4) match your current setup. When replacing a rear wheel with a hub motor, also inspect the condition of the wiring, connectors, and controller: a damaged connector or a pinched cable sheath can cause interruptions in pedal assist. After installation, perform a static test (with the wheel raised) followed by a gradual test ride on the road to verify that the assistance is working properly and that there is no friction.
