Kick start is a method of starting an internal combustion engine (usually that of a motorcycle) by pushing a ratcheting lever with one's foot. Kick start mechanisms were almost universally a part of motorcycle engines before the mid-1970s, and were phased out of production over the next twenty years or so as electric starters became standard equipment. There are still some motorcycles produced that have both kick and electric starters.
Many mopeds and scooters also carry both a kick start and an electric start, the former being useful in case the latter fails, as scooter and moped batteries tend to be smaller and, as a result, run down much faster than other forms of automotive batteries. Also, it is usually not possible to push start a moped or scooter with automatic transmission.
Larger motorcycles featured a manual compression release mechanism that made starting easier while modern units did this automatically through a cable attached to the kick start lever.
Today, dedicated off-road motorcycles and many ATVs use kick start systems due to the increased weight of electric starters. The majority of the inexpensive two-wheelers and sometimes three-wheelers in developing countries also use kick start levers.
The first kick start motorcycle was a British Scott Motorcycle two-stroke twin manufactured in 1910.[1]
Some scooters have kick starters with a tendency not to always work if not performed correctly. Some manufacturers have also included kick starters in their models only for a purpose of introducing apparent convenience for ignition, as opposed to offering a reliable alternative for an electric starter.[

the When ignition switch of the bike is pressed, it allows a small current to flow through the solenoid present in the starter circuit.
When current passes through coil of solenoid, it attracts an iron rod. The movement of the rod closes two heavy contacts, completing the circuit from the battery to the starter. The powerful starter motor starts rotating. Its shaft carries a small pinion which engages with a large gear ring around the rim of the engine flywheel.
The ignition switch has a return spring, so that as soon as you release the key it springs back and turns the starter switch off. The rod also has a return spring -when the ignition switch stops feeding current to the solenoid, the contacts open and the motor stops. The return springs are needed because the starter motor must not turn more than it has to in order to start the engine. The reason is partly that the starter uses a lot of electricity, which quickly runs down the battery. Also, if the engine starts and the starter motor stays engaged, the engine will spin the starter so fast that it may be badly damaged.The starter motor itself has a device, called a Bendix gear, which engages its pinion with the gear ring on the flywheel only while the starter is turning the engine. It disengages as soon as the engine picks up speed.
So, ultimately, the starter system producesrotation of flywheel, and hence rotation of crankshaft, and thus the reciprocating motion of piston starts. After suction of charge, the first compression and first power stroke will occur due to starter and thereafter the flywheel will do its job to continue the rotation of the crankshaft.
