Yunzhilun 26-inch Bicycle Conversion Kit Electric Motor Wheel Alloy Hub with Lithium Battery 18650 12.6V5A Charger EU or US Plug Micro-Power Electric Bicycle Conversion
Yunzhilun 26-Inch Bicycle to Electric Bike Conversion Kit with Alloy Hub Motor

Upgrading a standard pedal bicycle to offer electric assistance is made straightforward with the Yunzhilun micro-power conversion kit. Designed specifically for 26-inch bicycle frames, this kit provides the core electrical components needed to add a motorised drive system. The central element is an alloy hub motor wheel that replaces the bicycle's existing front or rear wheel, integrating the motor directly into the hub for a clean installation. The system is powered by a rechargeable 18650 lithium battery, which comes with an integrated protection board to manage charging and discharging cycles. Completing the kit is a dedicated 12.6V5A charger, housed in a plastic shell and available with your choice of an EU or US electrical plug, making it suitable for use in different regions. This conversion approach offers a modular way to gain electric pedal assist without purchasing a complete new electric bicycle.
Features and Construction

The Yunzhilun kit is built around key components that work together to provide electric assistance. The construction focuses on integrating the motor into the bicycle's existing structure and ensuring safe electrical operation through managed battery systems.
Material and Build
The primary mechanical component is the motor wheel, which features an alloy hub. This material choice aims to provide a sturdy housing for the internal motor mechanism while contributing to the overall weight of the wheel assembly. The electrical system centres on a lithium battery of the 18650 type, a common cell format known for its rechargeable properties. This battery is not just a simple power source; it incorporates a charge and discharge protection board. This board acts as a safety controller, helping to prevent issues like overcharging or excessive discharge, which can affect battery lifespan and safety. The accompanying charger has an outer casing made from plastic, providing insulation and a lightweight shell for the internal electronics.
Size and Practical Fit
The entire conversion kit is designed for compatibility with bicycles that use 26-inch wheels. This is a standard wheel size found on many mountain bikes and hybrid bicycles, making the kit applicable to a wide range of existing cycles. The 'Applicable size: 26 inches' specification is crucial, as it defines the frame and fork clearance required for the new motorised wheel to fit correctly. The hub motor is built into a wheel of this diameter, so it directly replaces the bicycle's original 26-inch wheel. Buyers should verify their bicycle's current wheel size matches this specification before purchase to ensure a proper physical fit for the motor wheel installation.
Uses and Placement

This product transforms a manual bicycle into an electrically assisted one, expanding its utility for various riding scenarios. The installation integrates the motor into the bicycle's drivetrain, providing help where it's most effective.
Event or Professional Use
For delivery riders, community safety patrols, or anyone who uses a bicycle extensively for work-related travel, adding electric assistance can reduce physical strain over long shifts or hilly routes. The conversion kit allows a standard work bicycle to be upgraded to an e-bike, potentially increasing the range and speed achievable per trip without the upfront cost of a proprietary electric bicycle. The system's inclusion of battery protection helps manage power use during repetitive daily charging cycles, which is relevant for professional or frequent use. The choice between a Generation 1.0 or 3.0 battery may offer different levels of intelligent power management suited to demanding routines.
Everyday Home Use
For everyday commuters, leisure cyclists, or those living in areas with inclines, this kit can make cycling more accessible and less strenuous. It enables riders to travel further with less effort, tackle headwinds or slopes more easily, and arrive at their destination less fatigued. Converting an existing bicycle that is already comfortable and familiar can be more cost-effective than buying a new e-bike. The kit's design, with the motor hidden in the wheel hub, maintains a relatively standard bicycle appearance. The availability of chargers with both EU and US plugs adds convenience for households with different socket standards or for individuals who may travel with their converted bicycle.
Benefits and Buying Value

The value of this conversion kit lies in its specific component set and the flexibility it offers compared to a complete new electric bicycle. It provides a targeted upgrade path based on verifiable specifications.
Reuse and Low Maintenance
A significant advantage is the ability to reuse a bicycle you already own and are familiar with. There's no need to adapt to a completely new bike's geometry or handling. The system's maintenance revolves primarily around the electrical components: charging the lithium battery and ensuring connections are secure. The mechanical side involves standard bicycle wheel maintenance, such as checking tyre pressure and ensuring the wheel is properly secured in the dropouts. The protection board within the battery is designed to help maintain battery health over repeated charge cycles, which is a key factor in the long-term usability of any electric assist system.
Why Choose This Product
This Yunzhilun kit stands out for its clear specification for 26-inch bicycles and its inclusion of a battery with integrated protection circuitry. The option to select between battery generations (1.0 or 3.0) and charger plug types (EU or US) allows buyers to tailor the kit to their specific needs and location. The use of an alloy hub for the motor wheel suggests a focus on durable construction for the rotating assembly. The product provides a defined set of components—motor wheel, battery, charger—with stated parameters like voltage and amp rating for the charger. This factual approach allows for an informed purchase decision based on compatibility with an existing 26-inch bicycle and the provided electrical specifications.
