Yunzhilun Micro-Power Bicycle Conversion Kit with Lithium Battery and Alloy Hub

Transform your standard 26-inch bicycle into an electric-assist vehicle with the Yunzhilun conversion kit. This system replaces your existing front or rear wheel with a specially engineered alloy hub containing a micro-power motor. The kit is designed for straightforward installation, providing pedal assistance to extend your range and reduce effort on hills or longer journeys. It includes a crucial lithium-ion battery pack, certified to CCC standards, which features an integrated protection board to manage safe charging and discharging. You have a choice between two battery generations—1.0 or 3.0—allowing you to select the power level that matches your typical riding needs. A matching 12.6V 5A charger with a plastic casing is supplied, available with either a EU or US plug type for global convenience.

Features and Construction

The core of this conversion is the Imotor 3.0 third-generation intelligent micro-power wheel, a hub motor built to fit a standard 26-inch bicycle frame. Its construction and components are chosen for integration with existing bike hardware.

Material and Build

The motor hub itself is manufactured from an alloy, a material choice that aims to balance strength for supporting the bicycle and rider with a manageable weight for the wheel assembly. The included 12.6V 5A charger features a shell made from plastic, making it lightweight and durable for transport and home use. The battery cells are of a lithium type, a common technology for e-bike systems due to its favourable energy density.

Size and Practical Fit

The primary dimensional specification for this kit is its compatibility with 26-inch wheels. This is a standard bicycle wheel size, but it is essential to verify your bike's current wheel diameter before purchase to ensure a correct fit. The kit is designed to replace one entire wheel, so the hub motor's spoke flange and axle dimensions are made to suit standard 26-inch rim builds.

Uses and Placement

This product is intended for the specific purpose of adding electric pedal assistance to a human-powered bicycle. It is suited for various riding scenarios where a bit of extra power is useful.

Event or Professional Use

For delivery riders or individuals who use a bicycle for work-related travel over moderate distances, this conversion can provide consistent assistance, potentially reducing fatigue. The electric assist can help maintain schedule adherence when carrying loads or facing headwinds, turning a standard bike into a more capable utility vehicle.

Everyday Home Use

For daily commuters or leisure cyclists, the kit makes longer errands, hilly routes, or journeys in warm weather more accessible and less strenuous. It can encourage more frequent bike use by lowering the perceived effort required, offering a practical alternative to driving for short to medium trips around town.

Benefits and Buying Value

The value of this conversion kit lies in its specific components and the functional upgrade it provides to an existing bicycle, avoiding the need to purchase a complete new electric bike.

Reuse and Low Maintenance

The system utilises your existing bicycle frame, handlebars, brakes, and gears, adding only the motorised wheel and battery. This approach can represent a cost-effective path to electrification. The hub motor design is generally sealed and requires minimal maintenance compared to more complex mid-drive systems, and the dedicated charger simplifies the power cycle.

Why Choose This Product

This kit offers a clear specification for 26-inch bikes, a choice of battery generation for different power needs, and includes all critical components—motor hub, battery, and charger. The inclusion of a battery with charge and discharge protection addresses a key safety consideration for lithium batteries. The option to select the appropriate electrical plug (EU or US) for the charger adds convenience for international users.
