4 Reasons Your Rear Bike Wheel Wobbles Side To Side.

If you’ve ever taken your bike out for a spin and noticed that your rear bike wheel wobbles from side to side, you’re not alone. This is a common issue that can be caused by a number of different factors. Here are four of the most common reasons why your rear bike wheel may be wobbling:

1. Incorrectly tightened spokes: If your spokes are too loose or too tight, it can cause your wheel to become unbalanced and start wobbling. Make sure to check that all of your spokes are properly tightened before heading out for a ride.

2. Worn-out bearings: Another common cause of rear wheel wobble is worn-out bearings.

Over time, bearings can wear down and loosen, which will cause the wheel to become less stable. If you suspect that your bearings may be the problem, take them to a bike shop to have them checked out and replaced if necessary.

3. Bent axle: A bent axle is another potential cause of rear wheel instability.

If you hit a pothole or bump into something while riding, it’s possible to slightly bend your axle without realizing it. This can lead to an uneven distribution of weight on the wheel, causing it to wobble from side to side. Inspect your axle regularly for any signs of damage or bends.

4 . Tire pressure: Believe it or not, even something as simple as tire pressure can affect the stability of your rear wheel.

If your rear bike wheel is wobbling side to side, there are a few possible causes. First, check to see if the quick release skewer is tight. If it’s loose, tighten it until the wheel is secure.

Next, check the hubs to see if they’re properly aligned. If they’re out of alignment, you’ll need to adjust them. Finally, check the spokes to see if any are loose or broken.

If so, replace them with new ones. If you’ve checked all of these things and your rear wheel still wobbles, it’s likely that the frame is bent or damaged in some way. This is something that can only be fixed by a professional bike mechanic.

Side to Side Play in Rear Wheel

Side to side play in a rear wheel can be caused by several things. Most often, it is due to worn bearings or bushings. It can also be caused by a bent axle or frame, or by the wheel itself being out of true.

If you suspect that your rear wheel has side to side play, the first thing you should do is check the bearings. If they are worn, they will need to be replaced. You can usually tell if bearings are worn by feeling for roughness when you spin the wheel.

Another way to check is to remove the axle nut and washer on one side of the hub, and then try to move the axle back and forth. If there is any play, the bearings are worn and need to be replaced. If the bearings check out OK, then it’s time to check the bushings.

To do this, remove the entire rear wheel from the bike and hold it in your hand with the brake rotor facing up. Grab onto either end of an spoke and try to wiggle the rim from side to side. If there is any movement at all, then one or more of your bushings is worn out and needs replacing.

In some cases, side to side play in a rear wheel can be caused by a bent axle or frame. This is usually easy enough to spot visually – just take a close look at your axle or frame tubes and look for any bends or kinks. If you see anything that looks even slightly off-kilter, then chances are good that this is what’s causing your problem (although it could also just be an optical illusion created by something else entirely).

The only way to know for sure is to take your bike into a shop and have them check it out – don’t try straightening it yourself unless you’re absolutely confident in your ability (and even then I’d recommend against it!). Finally, sometimes a rear wheel can become “out of true” – meaning that its spokes are no longer evenly tensioned around the rim so that it doesn’t spin perfectly smoothly anymore. This usually happens as a result of hitting hard objects while riding (like potholes), but can also happen simply from regular use over time as well as from poor initial spoke tensioning when building up wheelsets from scratch (I’m guilty of this myself!).

What Causes a Rear Bike Wheel to Wobble?

Bike wheels are designed to be strong and stable, but sometimes a rear bike wheel can start to wobble. There are several potential causes of this problem, including: 1. Loose spokes: If one or more of the spokes on your rear wheel is loose, it can cause the wheel to become unbalanced and start to wobble.

You’ll need to tighten any loose spokes as soon as possible. 2. Worn-out bearings: The bearings in your rear wheel help keep it spinning smoothly. If they become worn out, they can cause the wheel to start wobbling.

You may need to replace your bearings if they’re worn out. 3. Bent axle: If your rear axle is bent, it can also cause your wheel to wobble. This is usually caused by an impact (such as hitting a pothole), and you’ll need to get your axle straightened or replaced if it’s bent.

How Do You Fix a Wobbly Bike Wheel?

Assuming you’re talking about a wheel that’s come loose from the axle: First, check to make sure that the axle is tight in the frame. If it’s loose, tighten it up with a wrench.

Next, take a look at the spokes. If any of them are loose, tighten them up with a spoke wrench. You may need to adjust some of the other spokes to get everything nice and tight.

If your wheel is still wobbly after doing this, it’s possible that your rim is damaged and needs to be replaced.

Why is My Wheel Wobbling Mtb?

One of the most common questions we get asked here at MTB HQ is ‘Why is my wheel wobbling?’ We feel your pain, a wobbly wheel is not only annoying but can be dangerous too. Here are some tips on how to stop your wheel from wobbling and get back to shredding those trails! First things first, check that your bike is properly set up.

This includes checking that the wheels are securely attached, the brakes are working properly and that the suspension isn’t loose. If everything looks good there then it’s time to take a closer look at the wheels themselves. If you have disc brakes then it’s worth checking that the rotor isn’t warped or bent as this can cause a wobbly wheel.

You should also check that the hub bearings aren’t loose as this can also cause problems. If you have rim brakes then make sure that the pads aren’t rubbing on the rims and that the rims themselves aren’t damaged or out of true. Once you’ve ruled out all of these potential causes it could be that your spokes are simply loose.

This is easily fixed by tightening them up with a spoke key but if they keep coming loose then it might be worth getting new spokes fitted. Hopefully these tips will help you fix your wobbly wheel problem but if not then please feel free to get in touch with us here at MTB HQ and we’ll do our best to help!

How to Fix a Loose Wheel Bearing on a Bike


If your rear bike wheel is wobbling from side to side, it could be due to one of four reasons. First, your wheel may not be properly attached to the frame. Second, your spokes could be loose.

Third, your hub could be loose. Finally, your tire could be low on air. By checking each of these things, you can narrow down the cause of the problem and fix it accordingly.
