Yunzhilun bicycle electric conversion kit with 18650 lithium battery and alloy hub motor for 26-inch bikes

Features and Construction

Material and Build
The battery utilises 18650 lithium cells, a format commonly used in electric vehicles, housed in a protective casing with integrated charge and discharge protection circuitry. This provides multiple safety layers during operation. The motor features an alloy hub construction that maintains strength while keeping weight manageable for bicycle applications. The charger housing uses plastic materials for electrical insulation and impact resistance.Size and Practical Fit
This kit is designed specifically for 26-inch bicycle wheels, a common size for adult bicycles. The components are engineered to integrate with standard bicycle frames without requiring extensive modification. The hub motor replaces your existing bicycle wheel hub, maintaining the original wheel diameter while adding electric assistance capability.Uses and Placement

Event or Professional Use
For delivery services, campus transportation, or recreational touring, this conversion provides pedal assistance that reduces rider fatigue on longer journeys. The 18650 lithium battery technology offers energy density suitable for moderate-distance travel between charges. The system maintains bicycle handling characteristics while adding electric power when needed.Everyday Home Use
For commuting, shopping trips, or family outings, this conversion extends your bicycle's practical range without requiring a complete new vehicle purchase. The system integrates with your existing bicycle, preserving your familiar riding position and storage requirements. Charging occurs via the included 12.6V5A charger with your choice of electrical outlet configuration.Benefits and Buying Value

Reuse and Low Maintenance
The conversion allows continued use of your existing bicycle frame, components, and accessories while adding electric assistance. The lithium battery technology requires only periodic charging rather than complex maintenance, and the hub motor design integrates simply with your bicycle's existing wheel. The system doesn't require specialist tools beyond standard bicycle maintenance equipment for installation.Why Choose This Product
This kit provides electric bicycle capability without replacing your entire bicycle. The 26-inch wheel compatibility covers many adult bicycle models, and the choice between battery generations lets you select the appropriate power level. The inclusion of both battery and charger in the package means you receive a complete working system rather than sourcing components separately.
