The Yechiry Electric Brushless Motor Kit presents itself as a compelling option for cycling enthusiasts and DIY builders seeking to electrify their bicycles, tricycles, or light motorcycles. Designed with practicality and performance in mind, this 12V 120W motor kit combines essential features that cater to both novice and experienced users looking to embark on custom electric vehicle projects. Its specifications and design choices reflect a focus on efficiency, durability, and ease of integration—qualities that resonate well within the cycling community.
At the core of this kit lies a 12V 120W brushless motor, engineered to deliver reliable power for urban commuting or leisurely rides. The motor’s permanent magnet DC design is a standout feature, offering improved energy utilisation compared to traditional brushed alternatives. This efficiency not only extends battery life but also ensures smoother acceleration, a characteristic that users have highlighted as beneficial for stop-start city traffic. The 120W output strikes a balance between performance and practicality, providing sufficient torque for moderate inclines without overwhelming the electrical system. While it may not cater to high-speed racing or heavy cargo loads, this power range is well-suited for lightweight builds, aligning with the needs of cyclists prioritising energy conservation over raw speed.
Constructed from high-grade aluminium alloy, the motor’s housing exemplifies robust engineering. Aluminium’s natural corrosion resistance and structural integrity make it ideal for outdoor use, particularly in the UK’s variable climate. Enthusiasts have appreciated the material’s lightweight properties, which contribute to overall vehicle agility. Complementing this is the use of all-copper windings within the motor, a detail that underscores longevity. Copper’s superior conductivity and heat resistance mitigate energy loss and reduce the risk of overheating during prolonged use—a critical factor for riders tackling longer commutes. The inclusion of an air-cooling system further enhances thermal management, ensuring consistent performance even during extended rides.
Installation simplicity emerges as a recurring theme in user feedback. The kit’s comprehensive nature, which includes a 25H 76-link chain and a 25H 3-hole 47-tooth crank set, eliminates the need for sourcing compatible components separately. The chain’s durability and precise tooth engagement have been praised for minimising slippage, a common frustration in DIY conversions. The crank set’s design facilitates straightforward alignment with bicycle frames, reducing installation time. While some technical knowledge is required for optimal setup, the overall process is described as manageable for those with basic mechanical skills. The motor’s compact dimensions and lightweight profile further simplify integration, particularly for builders working with limited frame space.
Performance characteristics such as low noise operation and smooth power delivery are frequently cited advantages. The brushless design inherently reduces mechanical friction, resulting in quieter performance compared to brushed counterparts—a feature appreciated by riders who value a near-silent ride through urban or rural settings. Users have noted the motor’s ability to maintain consistent speeds on flat terrain, with responsive throttle input ensuring intuitive control. The absence of cogging, a common issue in lower-quality motors, contributes to this seamless experience, making it suitable for riders who prioritise ride quality over outright power.
Versatility is another key strength. Though marketed primarily for bicycles, the motor’s 12V configuration and adaptable mounting system make it viable for tricycles and lightweight motorcycles. This flexibility has attracted attention from hobbyists experimenting with unconventional builds, such as cargo trikes or compact urban runabouts. The motor’s compatibility with standard bicycle chains and sprockets allows for easy gear ratio adjustments, enabling users to fine-tune their setup for specific use cases—whether optimising for hill-climbing capability or maximising top speed on flat stretches.
Durability testing in real-world conditions has yielded positive observations. The aluminium housing’s resistance to road debris and moisture aligns well with the UK’s damp riding environment. Riders have reported reliable performance across seasons, with no noticeable degradation in power output or efficiency after months of regular use. The sealed bearing system and corrosion-resistant fasteners contribute to this resilience, reducing maintenance requirements. However, some users recommend periodic lubrication of the chain and routine checks on electrical connections to ensure long-term reliability—a practice consistent with any electric conversion kit.
Comparative analysis against similar offerings in the market reveals distinct advantages in weight-to-power ratio and component quality. While higher-wattage motors exist for performance-oriented builds, this kit’s 120W output provides adequate thrust for everyday use without necessitating bulky battery packs. The all-copper windings and precision-machined gears position it above entry-level models that often compromise on internal components. For recreational cyclists and commuters seeking a balanced blend of efficiency and practicality, these attributes make a compelling case.
In practical application, the motor excels in urban environments where its modest power output aligns with legal restrictions on electrically assisted bicycles in many regions. The smooth power delivery proves advantageous in crowded streets, allowing for precise speed modulation. Weekend riders have found it particularly suitable for converting traditional bicycles into hybrid models, preserving the bike’s original handling characteristics while adding electric assistance for longer journeys. The kit’s adaptability to various wheel sizes and frame geometries further broadens its appeal, accommodating everything from folding bikes to vintage road frames.
Environmental considerations also come into play. The motor’s energy-efficient design complements the growing trend towards sustainable urban mobility. By enabling the conversion of existing bicycles rather than requiring entirely new electric models, it supports circular economy principles—a point increasingly valued by eco-conscious riders. The longevity of its copper and aluminium components reduces waste, aligning with broader environmental goals within the cycling community.
User feedback consistently highlights the satisfaction derived from the DIY aspect of the kit. The sense of accomplishment in creating a personalised electric vehicle, coupled with the motor’s reliable performance, forms a recurring narrative. Enthusiasts appreciate the clarity of installation guidelines and the logical layout of components, which reduce trial-and-error during assembly. For those new to electric conversions, the learning curve is described as manageable, with online communities and resources providing additional support where needed.
In conclusion, the Yechiry Electric Brushless Motor Kit stands as a thoughtfully engineered solution for electric bicycle conversions, blending essential performance metrics with user-friendly design. Its emphasis on durable materials, energy efficiency, and adaptable installation caters to a broad spectrum of DIY projects. While not without limitations in extreme performance scenarios, it fulfils its intended purpose as a reliable, accessible option for everyday electrification needs. For cyclists seeking to venture into custom electric builds without compromising on quality or practicality, this kit offers a balanced foundation.
