How to Start a Moped

Mopeds are fun, environmentally-friendly ways to get around. They are motorized bicycles, having an engine but also telltale bike pedals. Still, they can be tricky to start, especially if yours is vintage or has been idle for a while. To start your moped, flip on the kill switch, squeeze the brakes, then hit the start button for a conventional start or peddle first for a moving start.

Put the key in the ignition. Turn it to the right until it clicks in place, signifying that the ignition has been engaged.
Since mopeds generate automatic movement, they have a kill switch to shut them down quickly. The kill switch is a colored switch near the handlebars. Find it and flip it to the on position, which is often represented as an open circle.^{[1]XResearch source}

Squeeze the brake levers. The brake levers are on the moped’s handlebars. The back brake is necessary to engage and is activated by the left lever. However, it’s easier to hold both until you are ready to drive.^{[2]XResearch source}
- The moped will move automatically when you start it, so if you don’t have the back brake engaged, you’ll pitch forward.
Continue holding the levers. Use your thumb to hit the start button. This will often be a red button near the right handlebar. Once you hear the motor start, you are free to release the brakes and drive.

Turning on a Vintage Moped

Put the key in the lock. Vintage brands such as Puch have more complicated starting processes. First, if the lock has been engaged, start unlocking the moped using the keylock right below the handlebars. Move the handlebar to the right. Put the key inside the lock.
- Be aware that different brands may require more or less steps to start.
First, turn the key to the right. When it is turned to the right, you should be able to push it in. Once you do that, turn the key back to the left until the moped is unlocked.
On a Puch Maxi, for example, you’ll find the fuel valve on the right side of the moped’s frame. This is a switch you must turn off when you park the moped. You may see the “on” and “off” labels on your moped. Pull the lever into the “on” position.
Look near the handlebars for the engine switch. On the Puch Maxi, it’s on the right side. Make sure the switch is flipped to the “run” position.
This only needs to be done if the engine is cold from disuse. Locate the carburetor. It’ll have a small black bar poking out of it. This is the choke, which you need to press and hold. While you do this, look downwards and find the small primer button on the carburetor. Press this too.
Hold the front brake, which is on the right side of the handlebars, so you keep the moped under control. Find the starting lever under the left handlebar. Keep the pedals level as you pull it.^{[3]XResearch source}
Continue holding the starting lever as you begin to pedal. The engine should start and you should be free to go. If it doesn’t start, you may need to try pedal-starting it.

Kickstarting a Moped

Pedal starting is useful for starting a struggling engine and moving from a stop. Get the key in place. Turn it to the right until it clicks to show that the ignition has been engaged. Do this before you start pedaling so you don’t have to fumble with the key.
Work the pedals like you would a bicycle. Release the kickstand and push forward to get a little momentum. Pedaling will be a little difficult because of the weight of the moped, but keep going until the starting process is complete.

Press the start button. Find the start button on your moped. It may be a red button near the right handlebar or a lever on the left handlebar. Some vehicles may also have a kickstart lever on one of the wheels that you can hit with your foot instead. Use this to start the motor.
- Since you’re already moving, don’t hit the brakes.
Locate the throttle. It is likely on the right handlebar. Lay your palm flat on the throttle, then gently turn it towards you. This opens the throttle as you move, allowing more air to enter the engine. Continue to twist the throttle to accelerate.^{[4]XResearch source}
With the motor started, the moped should be moving without you having to pedal. Adjust your body as the force of movement pulls you back. Stay straight with your eyes on the road as you let go of the starting lever or button if you haven’t yet.

Remove the spark plug. To check the ignition spark, find the plug on the engine. Make sure the kill switch near the moped’s handlebars is off before you do this. Try to start the moped. If the engine works, you should see a spark inside of it. Your finger would pop off if you held it over the hole.^{[5]XResearch source}
- If the spark plug looks dirty, try a new one.
- If the engine won’t start at all, you may need a new battery.

Check the gas. Open the fuel tank. If the gas has been sitting in there for at least a month, water will gather at the bottom of the tank. Unscrew the drain screw on the carburetor or undo the hose so that the water comes out. Catch any gas in a container.
- Use compressed air to blow debris out of the carburetor.
If you’re sure there’s a spark, gas infusion, and air moving through the moped, try pressing the choke. It’s the small black rod sticking out of the carburetor. Press it and try to start the engine. If it sounds like it is trying to start, open the throttle, which may be operated by turning the right handlebar towards you. Try starting the engine a few times while doing this.^{[6]XResearch source}
