Yunzhilun 26-Inch Bicycle Electric Conversion Kit with Alloy Hub Motor and Lithium Battery

Upgrade your standard pedal bicycle to an electric-assist model with the Yunzhilun micro-power conversion system. Designed for 26-inch wheels, this kit centres on a dedicated alloy hub motor that replaces your existing bicycle hub, providing a integrated power source. The system is powered by your choice of 18650 lithium battery pack, available as either a 1.0 generation or an updated 3.0 generation unit, both managed by an onboard protection circuit. Your purchase includes a matching 12.6V5A charger with a plastic housing, and you can select the appropriate electrical outlet plug—either EU or US standard—for your location. With CCC product certification, this kit offers a structured path to electrifying your bicycle, focusing on core mechanical and electrical compatibility.

Features and Construction

The conversion kit is built around several key hardware components designed for bicycle integration and electrical safety. The selection options allow you to tailor the system to your specific battery preference and geographical power outlet requirements.

Material and Build

The primary driving component is the Imotor 3.0, described as a third-generation intelligent micro-power wheel. Its construction uses an alloy hub, making it a sturdy focal point for the conversion that replaces the standard hub in a bicycle wheel. The included charger features a shell made from plastic, providing a lightweight and practical housing for the electrical components. The power source itself utilises 18650 format lithium battery cells, a common type found in many rechargeable devices, housed within either the 1.0 or 3.0 generation battery pack.

Size and Practical Fit

The stated applicable size for this conversion kit is 26 inches, which refers to the wheel diameter of the bicycle it is designed to fit. This measurement is crucial for ensuring the alloy hub motor is compatible with your bicycle's frame and existing wheel rim. The kit does not provide additional dimensional data for the battery packs or charger, so verification of storage space on your bicycle frame for the selected battery unit is recommended. The hub motor integration is intended for standard 26-inch bicycle wheel builds.

Uses and Placement

This product is designed for a single, clear purpose: converting a human-powered bicycle into an electric-assisted one. The application is straightforward but requires matching the kit components to your bicycle's specifications and your local electrical infrastructure.

Event or Professional Use

For delivery riders, tour guides, or anyone using a bicycle for work over moderate distances, adding electric assistance can reduce physical fatigue and potentially increase range or carrying capacity. The 26-inch size targets a very common bicycle format used in many urban and utility contexts. The CCC certification indicates a level of regulatory compliance for the electrical components, which can be a relevant factor for commercial or frequent use where equipment standards are important.

Everyday Home Use

For the casual cyclist, this conversion kit offers a way to make hill climbs easier, extend the range of leisure rides, or simply add a boost for commuting without switching to a completely new vehicle. The option to choose between battery generations (1.0 or 3.0) allows you to select based on anticipated performance or possibly cost, though specific differences are not detailed in the source. Selecting the correct charger plug (EU or US) ensures convenient home charging without the need for a travel adapter.

Benefits and Buying Value

The value proposition lies in converting an existing bicycle rather than purchasing a complete new electric bike, which can be a more economical and sustainable choice. The kit provides the essential electrical and mechanical components needed for this transformation.

Reuse and Low Maintenance

By converting your current 26-inch bicycle, you extend its useful life and avoid the full cost and resource use of a new electric bicycle. The system includes a charge and discharge protection board, which is a fundamental safety feature for lithium batteries that helps manage their lifecycle. The alloy construction of the hub motor suggests a focus on durability for a core moving part. General care involves using the supplied charger correctly and following standard lithium battery handling practices, such as storing in moderate temperatures.

Why Choose This Product

This kit offers a specific solution for a 26-inch bicycle conversion with clear component choices. The inclusion of CCC certification and a protection board addresses basic safety and compliance concerns for the electrical system. The ability to select your battery generation and charger plug type provides a degree of customisation to match your needs and location. It is a practical option for those who have a suitable bicycle and wish to add electric assist with a defined set of components.
