Not everything lasts forever and the wheel rim of your BMX bike, too, will need to be replaced when necessary. So, when is it necessary to replace the wheel rim of a BMX bike? Well, if you have been using the same wheels on the bike for a long period, you should understand that the rim is constantly compressed because of your weight. And, for every rotation the wheel takes, the spoke is loaded and unloaded, causing fatigue and wear on the wheel. Other aspects that contribute to the wear of the wheel include lateral loads. Lateral load simply means the load the rider transfers from one side of the bike to the other side when pedaling. When the rims are worn off, there is no other solution but to get them replaced.

You need not worry about replacing the wheel rim of your bike if you follow the simple steps below. The steps will also come in handy if you need to disassemble your bike and make it portable for transportation.
Removing Your Front Wheel Rim
- You should first proceed to release your rim brakes or cantilever brakes if you´ve got them. In order to that, you need to release the cable tension. If your bike boasts of a rim brake, you can release some cable tension by using a lever near the caliper.
- You can either use a mechanical repair stand or flip your bike over to release the wheels. This prevents the bike from falling off after the removal of the wheel. In order to remove the front wheel, you will generally require an adjustable wrench, ratchets, and socket sets. You can then loosen the nuts that are used to keep the wheel stable.
- If you have rim brakes, you should remove the front wheel slowly, making sure that the calipers are not dislodged.
Putting a New Front Wheel Rim
- You should place your new front wheel rim into the fork without dislodging your calipers. The nuts of the new front wheel rim should be backed off so that you can place your wheel rim into the fork. And, your washers too must always be up against the nut and not on the other side. You should avoid installing your new front wheel rims if the wheels don´t have washers.
- After placing the wheel, you should ensure that the wheel is aligned to the center of the fork. Then, you can proceed to tighten the nuts, bolts, and whatever necessary.
Removing Your Rear Wheel Rim
- In order to remove the rear wheel rim, you will generally require an adjustable wrench, ratchets, and socket sets. You can then loosen the nuts that are used to keep the wheel stable.
- You should then disengage the brakes in order for you to take the wheel off. Then, you should take your chains off; moving the pedals backwards will help you remove the chains easily. After the chains come off, you should be able to remove the rear wheel rim.
Putting a new Rear Wheel Rim
- You should place your new rear wheel rim into the fork and then put the chain onto the chain wheel. After doing so, you can then re-engage your brake and then proceed to put the chain back onto the freewheel. You can then tighten the chain.
- Make sure the wheel is aligned evenly with the body frame of the bike before you proceed to tighten the nuts. While tightening the nuts, you shouldn´t tighten the nut on one side of the bike all the way before proceeding to the next side as it is not good for your hub.
- After the rear wheel rim is firmly placed, you should then spin your wheel and ensure that the brake pads aren´t rubbing the rim or the rotor. And, if you see that your wheel is not spinning well, it could be because it is crooked in the fork´s dropouts. If that´s the case, you need to loosen the axle and fix the wheel before proceeding to tighten the axle again. Repeat this process until the wheel spins normally.
