1ć Battery type and capacity
Type: Lead acid batteries are heavy but low-cost, lithium batteries are lightweight but expensive, suitable for frequent charging scenarios.
Capacity: Voltage (48V/60V/72V) and capacity (Ah) jointly determine the endurance. For example, a 48V24Ah lead-acid battery has a range of about 60-80km, while a lithium battery has a longer range with the same capacity.
2ć Motor and controller
The motor power (commonly 350W-1200W) affects power and climbing ability. For urban commuting, choose 350W-600W, while for mountainous areas or load requirements, choose 800W or more.
The controller needs to be matched with a motor, and priority should be given to models with overload protection and good heat dissipation.
3ć Braking system
The combination of front disc brake and rear drum brake balances braking efficiency and cost, and dual disc brake is recommended for high-speed models.
4ć Tires and shock absorbers
Vacuum tires have better explosion resistance than regular tires, and the depth of tire tread affects grip. It is important to pay attention when riding in rainy weather.
Hydraulic shock absorption provides better comfort than spring shock absorption and is suitable for bumpy roads.
5ć Intelligent functions (optional)
GPS positioning, APP control, NFC unlocking, etc. enhance convenience, but may increase the cost of purchasing a car.
