● Single-cylinder, four-stroke, air-cooled, electric starting engine.

● The lightweight design (crankshaft, piston, piston ring) reduces friction and vibration and improves dynamic performance.

● LONCIN special mute technology, through the material and structure system improvement, effectively reduce the heat deformation of the valve structure and the engine noise.

● Using piston back cooling technology, forced lubrication and cooling piston and piston ring, reduce engine heat load.

● Cylinder offset technology: reduce the side pressure of the piston on the cylinder wall, reduce friction loss, and reduce fuel consumption.

● Using valve rotation technology, the valve and door line are seamlessly sealed to ensure that the engine performance does not degrade.

● The built-in reverse gear structure simplifies the vehicle layout.

● Optimize the transmission ratio of each gear to improve the starting and acceleration performance of the vehicle.

● Optimize the transmission mechanism for smoother and easier shifting.

● Optimized inlet and exhaust ports for fuller combustion.
