After the Shanghai International Bicycle Exhibition, several questions were repeatedly raised by visitors to the Lofandi booth. This FAQ summarizes two of the most common technical questions in a more formal format for OEM customers and e-bike brands.

Q1: What Is The Service Life Of The Product?

The source material states that the combination of internal gear hub and belt drive uses a fully enclosed structure, is designed for low maintenance, and can reach a service life of 30,000 km under specified conditions. It also states that the service life can be more than three times that of an external derailleur system.

For public website use, this type of claim should be connected to the corresponding test method, product model and operating conditions. In general, the technical logic is clear: a sealed internal shifting structure reduces exposure to dust, mud, rain and impact compared with exposed derailleur systems.

The internal gear and belt-drive combination also supports smoother shifting, a cleaner drivetrain and less oil contamination. It can help reduce chain drop risk and avoid oil stains on clothing, improving everyday user convenience.

Q2: Is Automatic Shifting Smooth? Will There Be A Noticeable Interruption?

The source material explains that compared with some products that need to cut power during shifting, creating an obvious interruption, Lofandi's shifting system is designed to deliver a smoother and more natural shift feel.

E05 and R900, respectively an electronic intelligent 5-speed internal gear hub and a hub motor electronic 3-speed internal gearbox system, use electronic shifting technology. Through electronic control and motor-driven execution, they support fast, precise and stable gear changes, helping the power connection feel more natural and continuous.

Fast Electronic Response

By moving away from traditional mechanical cable constraints, electronic signal transmission helps reduce delay and supports quicker shifting response. Any public claim such as millisecond-level response should be supported by approved test data before publication.

Accurate Gear Positioning

Each shift is controlled electronically, helping the gear position switch accurately. This can reduce the inaccuracy that may occur in traditional shifting systems due to cable stretch, wear or adjustment drift.

OEM Note

For OEM projects, the final shifting feel depends on product model, motor platform, controller matching, communication protocol, wheel size, load, riding scenario and calibration strategy. Vehicle drawings and electrical interface information should be confirmed before sampling.
