The NBPOWER 135mm dropouts e-Bike kit is a powerful option for those looking to convert their standard bicycle into a high-speed e-bike. With a motor power of 3000 watts and compatibility with a voltage range of 48V-72V, it promises robust performance and can achieve impressive speeds up to 100 km/h. This makes it an attractive choice for users seeking high-speed capabilities.

The kit includes a sine wave controller, which tends to offer smoother acceleration compared to traditional controllers, enhancing the riding experience. The TFT UKC1 Color display provides clear and easy-to-read information, further adding to user convenience. The kit is compatible with 26-inch wheels and requires a rear fork distance of 135mm, which is standard for many bicycles.

Installation might pose a challenge for beginners due to the technical nature of the assembly and the single-speed freewheel setup, which limits gear options. The required assembly suggests that this kit is best suited for those with intermediate skills or willingness to seek professional help. At 11 kilograms, the weight is something to consider if bike weight is a priority. While it provides significant power, the kit does not include a battery, meaning users will need to purchase one separately that matches the voltage specifications. This kit is ideal for adult users focused on high-speed and powerful performance, but may not be suitable for those seeking a more leisurely conversion or those with limited technical expertise.

The BAFANG Mid Drive Kit offers a versatile solution for converting traditional bicycles into electric bikes.

With its capability to reach speeds up to 45 KMH, it can significantly enhance your cycling experience whether you prefer throttle control, pedal assistance, or standard cycling modes.

Its compatibility is a major advantage, fitting a wide range of bicycles with bottom brackets from 68mm to 120mm, as long as they are disc or V-brake equipped and chain-driven. However, the installation might be a bit challenging for some as the 73mm screws are not included, and the battery must be purchased separately. The inclusion of essential tools like a wrench and crank removal tool, along with the availability of detailed manuals and online videos, does help ease the assembly process.

The kit also provides comprehensive add-ons like a brake lever, chainwheel, and optional LCD display, giving users the flexibility to tailor their e-bike to their preferences.
