The SICHENSH 350W Electric Bike Conversion Kit presents a compelling proposition for cyclists seeking to electrify their existing bicycles. Designed as a front hub motor system, this kit integrates a brushless gear series motor, an LCD display, and a five-speed adjustable gear system, all tailored to enhance the riding experience while maintaining a focus on practicality and performance. Its compatibility with 20” wheels makes it particularly suited to hybrid or commuter-style bicycles, offering a streamlined transition from traditional pedal power to electric assistance.
Key Specifications and Build Quality
Central to the kit’s appeal is its 350W brushless gear hub motor, engineered to deliver a no-load speed of up to 28 km/h and a loaded speed of 24 km/h. Operating at 36V with a 300 rpm output, the motor balances power and efficiency, achieving over 82% energy conversion efficiency according to the manufacturer. This ensures minimal energy waste, a critical factor for riders prioritising battery longevity. The motor’s construction combines aluminium, iron, copper, and magnet steel, materials chosen for their durability and lightweight properties. Users have highlighted the robustness of the hub assembly, noting its resilience to daily wear, particularly in urban environments where potholes and uneven surfaces are common.
The inclusion of an LCD display adds a layer of sophistication, providing real-time data on speed, mileage, battery status, and selected assistance level. Riders appreciate the clarity of the display, which remains readable in direct sunlight—a frequent grievance with cheaper alternatives. The five-speed adjustable assistance system allows for fine-tuned control over motor input, catering to varied terrains and rider preferences. Cyclists transitioning from manual bikes often commend the intuitive nature of the gear adjustments, which integrate seamlessly with existing drivetrains.
Performance and Usability
One of the standout features noted by users is the motor’s near-silent operation. Unlike some direct-drive hub motors that produce a noticeable hum, the brushless gear design minimises noise, making it ideal for riders who value a quiet, unobtrusive ride. This characteristic has been particularly praised by commuters navigating busy city streets, where auditory awareness of surroundings remains crucial.
The kit’s installation process, while requiring moderate mechanical aptitude, is described as straightforward for those familiar with bicycle maintenance. The front hub configuration simplifies alignment compared to rear hub systems, though some users recommend professional assistance for securing electrical connections to ensure waterproofing and reliability. Once installed, the system’s plug-and-play functionality allows riders to switch between electric and manual modes effortlessly—a feature appreciated by those who still enjoy traditional cycling but require assistance for longer journeys or steep inclines.
Riders frequently highlight the motor’s responsiveness. The immediate torque delivery from a standstill eliminates the lag associated with lower-tier conversion kits, providing a smooth acceleration curve that feels natural rather than jarring. This responsiveness is further enhanced by the LCD’s fault detection system, which alerts users to issues such as overheating or connectivity problems, preemptively addressing potential malfunctions.
User Feedback and Practical Insights
Feedback from cyclists who have adopted this kit underscores its versatility. Commuters emphasise its reliability over daily distances of 15–20 miles, with battery consumption varying predictably based on assistance levels. One rider noted that the system’s efficiency allowed them to complete a week’s worth of short urban trips without recharging, though this naturally depends on individual usage patterns.
The five-speed adjustment feature receives consistent acclaim. Riders utilising hilly routes appreciate the ability to dial up assistance for climbs while reducing input on descents, optimising battery usage. The granular control also benefits those who prefer a subtle boost rather than full motor reliance, preserving the physical aspect of cycling while easing fatigue.
Durability in wet conditions is another frequently cited advantage. The motor and wiring harness are reportedly well-sealed against rain and splashes, though submersion is discouraged. This resilience extends to the display unit, which remains functional even in heavy drizzle—a critical factor in the UK’s unpredictable climate.
Considerations and Limitations
While overwhelmingly positive, some users note that the 20” wheel compatibility may limit the kit’s applicability to certain bike frames. Cyclists with larger or non-standard wheel sizes must verify fitment before purchase. Additionally, the absence of an integrated battery in the kit means riders must source a compatible 36V battery separately, which could add to initial setup complexity.
A minority of users observed that the motor’s power output, while sufficient for moderate terrain, may struggle on exceptionally steep gradients unless paired with pedal input. This aligns with the kit’s design philosophy as an assistance system rather than a full-throttle replacement for human effort.
Conclusion
The SICHENSH 350W Electric Bike Conversion Kit emerges as a robust, user-friendly solution for electrifying conventional bicycles. Its blend of silent operation, responsive motor performance, and intuitive controls positions it as a strong contender in the conversion kit market. The integration of a comprehensive LCD display and five-speed adjustability caters to both novice and experienced riders, offering flexibility across diverse riding scenarios. While not without minor limitations, its emphasis on durability, efficiency, and ease of use makes it a worthwhile investment for cyclists seeking to extend their riding capabilities without sacrificing the essence of traditional biking.
