[0002] An electric bicycle primarily consists of a frame, battery, motor, and electronic control system (controller). The frame is the supporting structure of the entire e-bike, upon which all other components are mounted. The motor provides propulsion, while the electronic control system manages the entire vehicle's circuitry. The battery, used to store electrical energy and power all electronic devices and the motor, is a critical component essential to the operation of an e-bike.

[0003] Frames are typically constructed of high-strength steel or aluminum alloy, materials that provide sufficient strength and durability. Frame design must consider not only structural stability but also battery installation and mounting. The integration of the battery and frame directly impacts the performance and safety of the vehicle. As a core component of an e-bike, the battery must be securely and reliably fixed to the frame.

[0004] The battery is usually installed behind the seat tube of the electric bicycle frame, but this installation method usually reduces the free space available on the electric bicycle frame, causing most of the weight of the entire vehicle to be distributed on the rear side. In addition, the installation method is not simple enough and requires the provision of a handle, a battery lock, etc. Utility Model Content
