1. The lightest portable electric wheelchair. This entire wheelchair is made of aluminum alloy for aviation use, and therefore, it is featured as light weight but high strength. Its standard bearer is 100KG, and the wheelchair weighs only 23KG (conventional electric wheelchairs weigh 40-150KG). 2. The smallest size portable electric wheelchair. It is foldable from front to rear, so its compact structure makes a maximum utilization of space (conventional electric wheelchairs are folded from left to right, so large and uneasy to carry around bulky). 3. The most energy efficient electric wheelchair. It is the first in the industry to use high-speed brushless DC motor, and the efficiency rate of its high speed torque motor can reach 80% (conventional electric wheelchairs are equipped with a brush motor, their efficiency is only 50% and the brush needs to be replaced every 2 years). 4. The longest service life. It is the first in the industry to use lithium battery, whose cycle life can reach up to 500 times or more (conventional electric wheelchairs use lead-acid battery whose cycle life is less than 200 times). 5. The lowest carbon-based electric wheelchair. It is the first in the industry to install solar panels in the electric wheelchair, and can be charged at any time during the day, which accomplishes the real zero carbon emissions. 6. The most beautiful and user-friendly electric wheelchair. It is specially designed for Chinese disabled persons according to human engineering mechanics. It is suitable for Chinese people's physical structure (the original design of conventional electric wheelchairs that comes from Europe or Japan is not suitable for the Chinese human structure, and some may even cause further damage). 7. The most convenient and practical electric wheelchair. The battery can be plug in and replaced fast and easily. The joystick, easily removable, can be controlled by both left and right hands. The storage bag is convenient and practical. Movable leg guards facilitate the activities. The anti-tilt structure shortens rotary radius, so suitable of indoor use. Movable handles can easily be operated (conventional wheelchairs are with fixed structure, cannot be adjusted or conveniently used). 8. The most secure and reliable electric wheelchair. Seat belts specially equipped for disabled persons, secure and adjustable handles, movable leg guards, anti-tilt structure, electronic brake + hand brake, warning light reflect poster, and 20 million times of fatigue impact test
