Therefore, it is important to be vigilant so as not to come across an mountain bike in poor condition.

The frame, a crucial part of the mountain bike

The frame is the part that supports all the peripheral elements of the ATV. To ensure your safety, it is important to check its good condition before buying a used mountain bike. If the frame is defective, it may cause the other parts of the bike to fail and possibly cause accidents. The frame is also subject to various mechanical stresses. Therefore, if it is not strong enough, it could not withstand shocks, vibrations, jumps, and even the weight of the rider. When inspecting the frame of a mountain bike, it is important to check :

The condition of the paint: if it is well maintained, it means that the owner has taken good care of his bike. If there are stickers added here and there, beware as these stickers can hide cracks in the frame.

The state of the welds: if you notice a crack in the welds, you should be careful as this means that the frame is weakened.

The existence of carbon fibre breaks on composite frames.

The fork, which must be checked on a second-hand bike

When inspecting a used bike, it is important to carefully inspect the fork. It is advisable to avoid models with cracks and deformations in the forks. If the MTB has a hydraulic fork, check for oil leaks: oil traces are often found on the fork sleeves. To check the condition of the fork, push the fork in deeply and then release it all at once, the tubes should come up easily, without jerking or snapping. You should also not see any drops of oil on the spinnaker seals.

Checking the headset

If it works properly, you should not feel any resistance when you turn the fork. To check whether the headset is working properly, put the bike in an upright position by pressing the rear wheel. Then turn the handlebars from right to left, if you do not feel any resistance it means that everything is fine. To complete the test, place the bike on both wheels, lock the front brake and make sharp back and forth movements. The movement must be smooth both on the brakes and on the fork.

Buying a second-hand bike: check the transmissions

On a bicycle in good condition, chainrings and sprockets must not have broken, sharp or bent teeth. There must also be no play between the chain and the chainring. When you pull on the cranks, the crankset must turn freely, without making any noise or marking.

Check the condition of the wheels on cheap mountain bikes.

The wheels are characteristic of ATVs. Before buying, it is important to check that the wheels are perfectly inflated and that they are free of impact or repair marks. If the wheels are of inferior quality, braking will be impaired and you will be unable to straighten the tires. Also check that there are no defective nuts or spokes that could make disassembly impossible in the future. When it comes to cheap ATVs, pay attention to the details. Check that the hubs are in good condition, i.e., they do not have any track markings, etc.

Rear Shock for full-suspension models

If the ATV is an all-suspended ATV, check that the rear shock absorber is impeccable. To do this, get on the bike and weigh your whole body while jumping on the bike. The shock absorber should slide freely, without making any noise.
