How do you start 150 minibike without a key?

To start a 150 minibike without a key, you can bypass the ignition switch by locating the ignition wires. Carefully strip the insulation from the two wires that connect to the ignition and twist them together to create a circuit. However, this method may not be legal and can lead to damage or theft, so it’s advisable to seek a replacement key or consult a professional. Always prioritize safety and legality when dealing with vehicles.
