Why some electric tricycles are so cheap than your imagine?
Why some electric tricycles are so cheap?
Survery from producer , dealer , parts factory will tell you the secrect.

Part |
Good electric vehicles |
Other electric vehicles |
|
Frame |
The national standard steel . This steel has smooth surface, thick wall, big strength ,won't rust | The steel does not meet the national standard, hot-rolled tubes, surface roughness, easy to rust, it is very thin, low-intensity, easy to break, lighter than brand 5kgs or more |
|
Motor |
Brand new motor,moderate Carbon content, low power consumption,save energy | Refurbished motor, demagnetization serious,high power consumption, big consumer of electricity,even heat and led to the cars can't run far |
|
Shell |
Material is ABS, which process is difficult and high strength to resist crash. Low coefficient of thermal expansion and contraction | Material is acrylic , cost is only 30% ABS, high coefficient of thermal expansion and contraction, the joint easy to crack, the cost is only about 40% of the good tricycle |
|
Charger |
Electronic components, circuit boards, fans all adopts high-quality parts, stable and durable performance | Using inferior refurbished components, no fan, electronic components poor stability, not durable, unstable parameters, cost about 1.5USD, only 30% of the brand charger |
|
Battery |
Battery from famous manufacturers | Refurbished batteries, battery run fast |
|
Controller |
Real materials,working stable, electric vehicle is powerful, good sealing | Noise, the cooling effect is not good, easy to make into water, pressure limit is weak, causing the battery perishable |
|
Welding |
Robot welding, weld poit is smooth, weld uniform solid, strong stability, security | Manual welding, uneven weld, not solid, easy to break, there are security risks |
|
Paint |
Paint thickness more than 50um | Paint thickness of about 15um |
|
Spray painting |
high-grade polyester paint and and advanced spraying, water-Fast | Common mixed paint,easy to fade when outdoor use |
|
Hubs |
Real aluminum materials, strength enough | None of aluminum, low-intensity, easy to fracture |
|
Brake |
Good brake,comes from brand manufacture,good braking effect | Inferior brakes, brake pads do not wear-resisting, long braking distance, poor braking effect |
