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

Upgrading a conventional pedal bicycle to electric assist is simplified with the Yunzhilun micro-power conversion kit. Designed for 26-inch wheel bicycles, this kit provides the core components needed for conversion: an intelligent motorised wheel, a lithium battery pack, and a dedicated charger. The system is built around the iMotor 3.0, a third-generation micro-power wheel that replaces your existing front or rear hub. With CCC certification and built-in battery protection, the kit offers a foundation for creating a personal electric bike, allowing you to select the specific battery generation or charger that suits your initial setup needs.

Features and Construction

The Yunzhilun conversion kit's functionality stems from its integrated component design, where each part is specified for bicycle electrification. The kit is not a single universal item but is offered in distinct configurations, enabling you to purchase either the latest motor wheel with a battery, an older battery generation, or just the charger as a replacement or standalone item. This modular approach allows for tailored purchasing based on whether you are starting a new conversion or supplementing an existing setup.

Material and Build

The primary mechanical component is the iMotor 3.0 micro-power wheel, which features an alloy hub. This material choice aims to balance strength and weight for the rotating centre of the wheel. The accompanying lithium battery utilises 18650-type cells, a common format in rechargeable power packs known for its energy density. The external charger supplied with the kit has a housing made from plastic, providing the necessary electrical insulation and basic physical durability for the charging unit itself.

Size and Practical Fit

The key dimensional specification for this kit is its compatibility with 26-inch bicycle wheels. This measurement determines which bicycles it can be fitted to, requiring the existing bike to use this standard wheel size for a direct wheel swap installation. The motor is integrated into the wheel hub, so the overall wheel diameter remains 26 inches, ensuring it fits within standard bicycle frame forks and stays designed for that size.

Uses and Placement

This product is intended for the specific use case of converting a non-electric, pedal-powered bicycle into an electric-assisted bicycle. It is suited for cyclists looking to add motorised help for hills, longer commutes, or reducing physical exertion, without purchasing a complete new electric bike. The requirement for a 26-inch frame makes it suitable for many adult hybrid, mountain, or city bicycle models that use this common wheel size.

Event or Professional Use

For casual or commuter use, the conversion allows a familiar bicycle to gain electric assist, extending its range and utility for daily travel, shopping trips, or recreational rides where extra power is desired. The kit’s design as a wheel replacement means the conversion can be reversible or transferred to another suitable bike, offering flexibility. The inclusion of safety certifications like CCC and a battery protection board indicates a design intent for reliable personal transportation use.

Everyday Home Use

As a home project, the conversion kit enables a bicycle owner to create a custom electric bike. The need to select the correct charger plug type (EU or US) at purchase is a practical consideration for home charging, ensuring compatibility with domestic wall sockets. The standalone charger option also serves as a replacement or spare part for existing setups, supporting long-term maintenance of the electric system at home.

Benefits and Buying Value

The value of this kit lies in its targeted function of bicycle electrification using a hub motor system, which is often simpler to install than mid-drive conversions. It provides a defined set of compatible components—motor, battery, charger—that are designed to work together. The choice between 1.0 and 3.0 battery generations allows buyers to match the kit to their performance expectations or budget, while the charger plug choice accommodates international users.

Reuse and Low Maintenance

The system promotes the reuse of an existing 26-inch bicycle frame, extending the life and functionality of a current bike rather than requiring a whole new vehicle. The lithium battery technology is rechargeable, supporting repeated use cycles. The availability of the charger as a separate purchase item aids in long-term upkeep, as this accessory can be replaced independently if needed.

Why Choose This Product

This kit is a considered option for those seeking a specific conversion solution for a 26-inch bicycle. Its clear compatibility parameter (26-inch wheels) helps buyers determine fit. The stated inclusion of a battery protection board and CCC certification addresses fundamental safety and quality concerns for an electrical product. The option to choose between EU and US charger plugs adds practical convenience for the user, ensuring the kit is usable in different regions without needing an adapter.
