How to Replace the Parts of Your Pocket Bike

Posted by Kenneth Poon on

Pocket bikes, whether they are gas powered mini bikes or electric ones, are constructed for racing competitions and should be used on special racing tracks and designated driving areas. It is also highly recommended that before you start hitting the road, you should understand how to use the minimoto and of course, practice safe driving at all times. Adults and youth alike can ride a pocket bike. However, it's recommended that youth only over the age of 13 year should drive a pocket bike due to it's speed and handling. it is important that a responsible adult person is supervising if youth are riding.




Pocket bike's are typically shipped in cardboard or wooden crates. In most cases minimal assembly is required. The brake levers, as well as the folded handlebars, are in the packaged too. After taking everything in the box, you need to setup the handlebars into a position that will suit you and make you feel more comfortable when driving. The maximum pulled brake lever position should not touch the handle grip.

Just before you start using it, you also need to fill the fuel tank with fuel. The fuel is a gas and oil mixture. If you fail to use the proper ratio of the oil mixture, it might cause engine damage to your brand new gas pocket bikes.

Just before starting, it is highly recommended to always follow all the instructions about the break-in period for your engine's reliability and long life. Your minipocketrocket’s break-in period will be complete after your bike was able to consume five full fuel tanks. Before the break-in period, you should be using either petrol 91 or 92 octane fuel mixed iwht synthetic oil at the ratio of 25:1. Afterwards, 49cc mini pocket bikes will run at a ratio of 50:1. Do not forget to mix the gas and the oil completely.

During your bike's break-in period, do not run the engine at maximum RPM. Do not allow the bike's engine to overheat as well. 




Replacing the front brake pads of your power wheels


Before you can replace the front brake pads of the bike, you need to losen the nut of the fine front brake adjustment. 


Removing and Replacing the Front Wheel


Before you will be able to remove and dismantle the front wheel of your bike, it is important to remove the front brake pads from the front brake. Removing the front brake pads from the front brake will allow you to move the brake caliper from the wheel and for you to draw out both the tire and the wheel. You can easily pull down the wheel from the forks after. Just be very careful in removing the wheel from the left side spacer or else, the washer will easily fall out.

While assembling everything, put the space washer between the brake caliper mount place and the brake rotor. Return all the nuts and bolts that you remove before performing a basic brake adjusting. This is the important part: Double check everything!


Removing and Replacing the Rear Wheel


Remove the car wheel axel nut. Loosen the nut located in the rear caliper anchor plate as well as the two-wheel adjustor plate nuts. Move the wheel forward and carefully remove the chain. For your safety, keep the rear wheel from falling out while you are removing the axel. 

Make sure to slide the brake rotor into the caliper between the pads. Hold the wheel in place and fit it into the wheel spacers in proper order.

You need to insert the space washer between the caliper plate and the brake rotor. Adjust the chain tension and tighten the axel nut after placing the axel spacers between the caliper plate and the brake rotor. Before checking the break operation, the most important part is to check everything first.




When your bike's tire is flat, you need to replace it right away to avoid accidents, especially if it is motorcycle for kids. For you to do it, you need to remove the wheel from the pocket bike first.


If you will be replacing the front wheel, you need to unbolt the brake disk while for the rear wheel, you need to unbolt the brake disk and the sprocket, remove the valve system, and deflate the tire. Carefully place the wheel on a hard and flat surface then press the tire bead from the wheel rim up to the middle relief of the center rim. Your tire is now ready to be removed from the rim and you can now replace it with a brand new and working one.




Dismantling the air filter is very easy. You just need to unscrew the bolt beneath it then ease the holder out. Afterwards, put down the suction chamber.

After doing these steps, you will have access to the filter. You may take off the filter by using a screw driver. Clean and lubricate it with engine oil before reassembling.

To mount the air filter again, you just need to follow these steps in reverse sequence.




If you're not using your pocket bike for extended periods of time, especially during winter, you still need to maintain it and take a few safety measures. Before you store it, make sure that you:

  • Remove the petrol from the fuel tank.
  • The storage space where you will be placing the pocket bike should be a smooth and dry place.
  • Protect the pocket bike from dust by covering it with large and thick sturdy plastic. 
  • Remove the spark plug, clean it thoroughly, then put some drops of fuel with oil into the cylinder. For the oil to be distributed, pull the starter rope two to three times. Screw the spark plug afterwards.
