Motivation through the chain-driven electric flywheel, and also installed at the rear axis expansion hub brakes, hub brakes and hold the brake hub, also installed on the tricycle has hydraulic brakes. Equipped with a front fork assembly in the hydraulic shock absorbers, rear axle equipped with spring damping structure column. Makes this a smooth operation of electric power tricycle, traveling comfort, climbing ability, and transportation safety. The utility model tricycle production technology is not complex, has produced three normal transport up to 600 days (during the day and transport, evening charge), did not find fault, because the use of designated outside the motor for the power transfer through short-chain-driven electric flywheel to reduce load , climb the slope when human help of electricity, the power to help human.
