Yunzhilun 26-Inch Bicycle Conversion Kit: Micro-Power System with Alloy Hub Motor

This Yunzhilun conversion kit provides a method to add electric micro-power assistance to a standard 26-inch bicycle. The system centres on a hub-mounted motor and a removable lithium battery pack, allowing you to retrofit pedal power with electric assist. It includes a 12.6V5A charger to replenish the battery and is certified to CCC standards, with built-in protection for charge and discharge cycles. The kit is designed for straightforward installation onto compatible bike frames, offering a practical upgrade path without requiring a complete new electric vehicle.

Features and Construction

The kit’s primary mechanical component is the Imotor 3.0, a third-generation intelligent micro-power wheel. Its construction and compatibility are key to its function, focusing on durable materials and a specific fit.

Material and Build

The motor unit features an alloy hub, providing a robust mounting point within the bicycle’s wheel. This material choice offers a balance of strength and weight for the rotating assembly. The included 12.6V5A charger has a housing made from plastic, which encloses the electrical components necessary for safely charging the lithium battery. The battery pack itself utilises the common 18650 lithium cell format, integrated with a protection board that manages both charging and discharging processes.

Size and Practical Fit

The entire conversion system is designed specifically for bicycles with 26-inch wheels. This stated size is crucial for compatibility, as the motor hub must replace the existing front or rear hub on a bike of this wheel diameter. The physical dimensions of the battery pack are tailored to mount on a standard bicycle frame, though exact measurements for the battery case are not specified in the source material. The system’s fit is defined by this wheel size parameter above all.

Uses and Placement

This product transforms a manual bicycle into an electrically assisted one, suitable for various riding scenarios where less pedalling effort is desired. Its application is defined by the kit's components and the rider's needs.

Event or Professional Use

For delivery riders or commuters covering regular routes on a 26-inch bike, this conversion can reduce fatigue over distance by providing consistent pedal assist. The micro-power system helps maintain a higher average speed with less physical output, which can be valuable for time-sensitive journeys. The removable battery allows for swapping charged packs to extend range, a practical consideration for professional use where downtime for charging must be minimised.

Everyday Home Use

For casual cyclists or those navigating hilly areas, the kit makes a 26-inch bicycle more accessible and enjoyable for leisure rides or running errands. The electric assist can help riders of varying fitness levels travel together more easily. Having the charger with a choice of EU or US plugs means it can be used in different regions, adding convenience for users at home or while travelling with their converted bicycle.

Benefits and Buying Value

The value of this conversion kit lies in upgrading an existing bicycle rather than purchasing a new electric model. It focuses on reuse, specified performance, and practical maintenance.

Reuse and Low Maintenance

The core benefit is extending the life and utility of a current 26-inch bicycle. Instead of buying a completely new electric bike, this kit reuses the frame, brakes, and most components. The system itself requires minimal routine maintenance beyond ensuring electrical connections are secure and keeping the battery charged. The protection board within the battery manages cell safety, reducing the need for user intervention in battery management.

Why Choose This Product

This kit is a suitable choice for someone with a compatible 26-inch bike seeking a defined electric assist system. Its advantages include the specified third-generation alloy hub motor for direct drive, the inclusion of a CCC-certified battery and charger, and the option for regional plugs. It provides a clear, component-based solution for conversion, with all necessary core parts included, allowing for a focused upgrade to micro-power cycling.
