The ELIKBH E-Bike Rear Wheel Conversion Kit offers a compelling solution for cyclists looking to transition their traditional bicycles into electric-powered machines without compromising the integrity of their existing setup. Designed for adult riders, this 48V 250W brushless gear motor system combines practicality with performance, catering to urban commuters and leisure cyclists alike. Its focus on stability, safety, and adaptability makes it a noteworthy contender in the growing market of DIY e-bike conversion kits.
At the heart of the system lies the 48V 250W brushless gear motor, engineered to deliver smooth, efficient power delivery. The brushless design ensures minimal maintenance, reduced noise, and improved longevity compared to brushed alternatives. Users have noted the motor’s ability to handle varied terrain with ease, whether navigating city streets or tackling moderate inclines. One cyclist remarked on the motor’s “surprising torque” for a 250W unit, highlighting its capability to maintain consistent assistance even under load. The motor’s integration into a 20-inch rear wheel ensures compatibility with a range of bicycle frames, though potential buyers should verify their bike’s dropout width and brake system compatibility prior to installation.
The inclusion of a KT controller and 130X thumb throttle provides intuitive control over power delivery. Riders can choose between three distinct modes: pure pedal power (ride mode), pedal-assisted cycling (PAS mode), and full electric operation (throttle mode). This versatility appeals to cyclists who value flexibility—commuters, for instance, might prefer throttle mode for quick acceleration at traffic lights, while leisure riders could opt for PAS to extend their range on longer journeys. The KT-BZ-4(8) PAS sensor, which detects pedalling cadence, has been praised for its responsiveness, with one user noting that the assist “kicks in seamlessly, without jerky transitions.”
Installation is a key consideration for DIY conversion kits, and ELIKBH has streamlined the process. The pre-laced 20-inch rear wheel, built around a double-walled aluminium rim, arrives ready to install, eliminating the need for complex spoke tensioning. The manufacturer estimates a 1-2 hour installation time for a single person, though some users recommend allocating additional time for first-time installers to familiarise themselves with wiring connections. A common observation among users is the importance of carefully following the wiring diagram to avoid damaging components—a reminder that attention to detail pays dividends. Notably, the kit excludes a battery, requiring users to source a compatible 48V unit separately. This allows cyclists to select a battery capacity suited to their range requirements, though it does add an extra step to the conversion process.
Safety features include a power-off brake lever that cuts motor output when engaged, a critical function for maintaining control during sudden stops. The LCD3 meter provides real-time data on speed, battery level, and assist mode, though some users have suggested the display could benefit from improved visibility in direct sunlight. The inclusion of a five-speed cassette accommodates existing drivetrains, preserving gear flexibility for pedal-only riding.
In terms of performance, the 250W motor complies with UK regulations for electrically assisted pedal cycles (EAPCs), making it road-legal when limited to 15.5mph assistance. Riders seeking higher speeds would need to consider regional legislation before modification. The brushless motor’s efficiency shines in assist mode, where multiple PAS levels allow for fine-tuned energy consumption. One cyclist reported achieving 40 miles on a single charge using moderate assistance, though actual range will vary with battery capacity, terrain, and riding style.
User feedback frequently highlights the kit’s durability in wet conditions, with sealed connectors and a waterproof controller earning praise for reliability during typical British weather. The aluminium construction of the wheel and motor hub contributes to an overall weight of 8kg—a consideration for cyclists prioritising portability or those with lightweight frames.
While designed for city bikes with front suspension, the kit’s compatibility with various frame types depends on specific measurements. Prospective buyers should verify their bicycle’s rear axle spacing (common sizes include 135mm or 145mm for older frames) and ensure adequate clearance for the motor’s width. The absence of a torque sensor means assistance is based on cadence rather than pedalling force, which some riders may find less natural compared to higher-end systems.
The ELIKBH conversion kit succeeds in democratising e-bike technology, offering an accessible entry point for cyclists reluctant to abandon their trusted bicycles. Its balance of functionality and simplicity resonates with users who value practicality over cutting-edge features. As one convert succinctly put it: “It’s given my old hybrid a new lease on life—suddenly hills feel flat and headwinds don’t matter.”
For those contemplating electrification without compromising their bike’s character, this rear-wheel conversion kit presents a compelling proposition. Its adherence to regulatory standards, coupled with robust construction and user-friendly operation, positions it as a pragmatic choice in the DIY e-bike market.
