Upgrade Description:
[Charger]
Enhanced Safety: Multiple intelligent protection systems have been added, including overcharge protection (automatically shuts off when fully charged), overtemperature protection (suspends charging when the temperature is abnormal), short-circuit protection, and reverse polarity protection, significantly reducing safety hazards during charging.
Durability Improvement: The outer shell is made of high-temperature-resistant, flame-retardant ABS material, offering improved drop and scratch resistance. The charging port is gold-plated to reduce oxidation during insertion and removal, ensuring a more stable connection and extending the overall lifespan of the charger.
[Battery]
Overcharge protection (automatically shuts off when the voltage exceeds the threshold) and over-discharge protection (triggers a low-battery warning when the charge level drops below 20%).
Physical Protection Improvement: The outer shell is made of a flame-retardant ABS+PC composite material, with temperature resistance increased to over 120°C and drop resistance increased by 50%. Insulating thermally conductive gel is filled between the battery cells to prevent short circuits and accelerate heat dissipation, preventing thermal runaway caused by high-temperature accumulation.
Extended service life and increased cycle count.

[Upgraded Front Axle and Screws]
Improved corrosion resistance prevents rust and seizure even in rainy and muddy conditions, ensuring smooth disassembly and maintenance. High-strength standards withstand greater radial impact forces (such as the transient stress of sudden braking and bumpy roads), reducing the risk of front wheel loosening due to screw deformation and breakage, and fundamentally ensuring structural stability during riding.

Utilizing a precision thread rolling process, the thread profile is more uniform, improving fit with the front wheel hub and frame connection holes by 30%, making it less susceptible to loosening due to vibration after installation.

Two new stainless steel wrenches enhance maintenance convenience and adaptability.

Specialized adaptability: The two wrenches correspond to the external hexagonal size of the screws, eliminating the need for users to search for additional tools. Whether performing daily inspections, changing tires, or adjusting the front wheel position, these tools are quick and easy to use, making them particularly suitable for non-professional users.

Upgraded durability: The wrenches are made of one-piece stainless steel with a hardness of HRC35-40. They are more resistant to bending and wear than ordinary carbon steel wrenches, resisting deformation and rusting over time. They can be used with the vehicle for extended periods, eliminating maintenance interruptions caused by tool damage.
