Bicycle wheel hub motor conversion kit for electric mountain bike refit, 3rd generation intelligent micro-power Imotor 3.0, alloy hub, available in black for AU and EU style specifications.
Imotor 3.0 Intelligent Micro-Power Wheel Hub for Converting Bicycles to Electric Mountain Bikes

Upgrading a conventional bicycle to an electric mountain bike can be a cost-effective alternative to buying a complete new e-bike. This conversion kit provides a core component for that project: the Imotor 3.0, a third generation intelligent micro-power system built into a wheel hub. The kit supplies one complete wheel with an integrated motor, designed for refitting onto a suitable bicycle frame. Finished in black and offered in configurations for both Australian (AU) and European (EU) style specifications, this hub motor allows cyclists to add electric pedal assistance. It is important for buyers to understand this is a technical component requiring installation, and compatibility with the recipient bicycle should be verified prior to purchase.
Features and Construction

The product is a self-contained conversion unit centred on its integrated motor technology and wheel assembly. Its design simplifies the electric bike conversion process by providing a major component as a single, pre-assembled item.
Material and Build
The hub of the wheel is constructed from alloy, a material frequently chosen for bicycle components due to its favourable strength-to-weight ratio. This construction houses the third generation Imotor 3.0 micro-power system. The intelligence referenced in the name suggests the motor includes some form of integrated control system, likely for managing power output, though specific details on its smart functions are not provided in the source material. The entire motor unit is contained within the hub, presenting a relatively streamlined aesthetic.
Size and Practical Fit
The product is listed as ‘Type: 0’, which typically denotes a specific wheel size or motor configuration standard within the manufacturer's range. Buyers must confirm this ‘Type 0’ specification matches the requirements of their bicycle frame, particularly the dropout spacing and wheel diameter. The kit is supplied as one complete wheel, meaning the tyre, tube, and rim are included, making it a direct replacement for an existing bicycle wheel. The availability in both AU and EU styles indicates there are regional variations, possibly relating to voltage, power output limits, connector types, or regulatory compliance, which should be checked against local laws.
Uses and Placement

This hub motor is designed for a specific retrofit application, transforming human-powered bicycles into electric-assist vehicles. Its suitability extends primarily to mountain bike frames but may work on other rigid-framed bicycles with compatible geometry.
Event or Professional Use
For bicycle mechanics, workshops, or rental businesses, this conversion kit offers a way to electrify existing fleet bikes or offer upgrade services to customers. The pre-built wheel assembly can streamline the installation process compared to kits that require lacing a motor into a separate rim. The dual AU/EU specification availability allows professionals to source the correct version for their market, ensuring compliance with local electric bicycle regulations, which often govern maximum speed and motor power.
Everyday Home Use
For the enthusiast or commuter, this kit enables the creation of a custom electric mountain bike. It is ideal for someone who already owns a suitable, good-quality mountain bike frame and wishes to add motorised assistance for tackling hills, extending range, or reducing fatigue on longer rides. The conversion preserves the feel and fit of the original bicycle while adding functionality. The user must be prepared for the technical task of installation, which involves fitting the wheel, connecting electrical cables to a battery and controller (not included), and potentially installing a throttle or pedal assist sensor.
Benefits and Buying Value

The value proposition lies in upgrading an existing asset rather than replacing it entirely, and in the specific features of this third-generation motor system. It represents a focused investment in the propulsion component of an e-bike build.
Reuse and Low Maintenance
A key benefit is the extension of a bicycle's useful life through electrification. The hub motor design is generally known for its simplicity and reliability, with fewer moving external parts than mid-drive systems. The sealed nature of the hub unit can contribute to lower maintenance, protecting the internal motor components from dirt and moisture—a practical advantage for mountain biking. As a complete wheel, it also eliminates the need for specialised wheel-building tools or skills.
Why Choose This Product
This kit is distinguished by its stated third-generation ‘intelligent micro-power’ Imotor system, which implies refinements over earlier versions, potentially in efficiency, control responsiveness, or power management. The clear option for AU or EU styles provides flexibility for international buyers or those in regions with differing e-bike laws. Choosing a complete wheel hub conversion can be a more straightforward path to an electric bike for those with mechanical aptitude, as opposed to sourcing a motor, wheel, and other parts separately. The alloy hub construction offers a balance of durability and weight expected in this product category.
