While the kit comes with many essential accessories, users will need to purchase the battery separately, which could add to the cost. The weight of the kit at 6 kg may also be a consideration for those looking to maintain a lightweight bike, particularly in steep terrains. The product is manufactured in China, which could lead to longer shipping times if you're located in a different region.

It provides three riding modes—full electric, pedal assist, and push assist—which offers flexibility depending on your riding needs, whether for longer commutes or exercise purposes. The motor is efficient and can reach speeds of up to 38-40 KMH, which is quite impressive for an e-bike conversion kit, and it includes essential safety features such as brake levers that cut off the motor power when applied. One of its significant strengths is the completeness of the package, which includes all necessary components and optional extras like a battery and LCD display.

Additionally, the global service centers in the US, EU, CA, and AU provide a safety net in terms of after-sales support and warranty services. However, at 19.84 pounds, it's relatively heavy, which might affect the handling of the bike, especially for those not used to electric bikes. Also, the battery and LCD display being optional means additional costs may be incurred if these are desired. Given its power and features, this kit is well-suited for intermediate users who seek a comprehensive and efficient solution for converting their bike to electric.

Installation is user-friendly, as the kit includes all necessary components such as the wheel hub motor, controller, display, throttle, brake levers, pedal-assist system, torque arm, and cable ties. However, the battery and tire are not included, which means you will need to purchase those separately. A notable drawback is the weight of the kit, which is approximately 15.8 pounds, possibly making the bike heavier and less agile.

The kit also comes with a 1-year warranty for the motor and battery, and a 3-month warranty for other components, which may not be sufficient for some users.
