Does Your Bum Hurt When You Ride Your Bike? Causes and Fixes Explained

If you’ve ever gone for a bike ride and ended up with a sore bum, you’re definitely not alone. Saddle discomfort is one of the most common complaints among cyclists, from beginners to experienced riders. The good news? It’s usually fixable.

Understanding why your bum hurts when you ride your bike is the first step toward a more comfortable experience.

Why Does Saddle Pain Happen?

Cycling places your body weight on a relatively small contact area—the saddle. If your setup or technique is off, pressure builds in the wrong places, leading to pain, numbness, or even chafing.

Common causes include:

Poor bike fit

Incorrect saddle choice

Lack of proper cycling gear

Riding posture issues

1. Incorrect Saddle Fit

Not all saddles are created equal. A saddle that’s too narrow or too wide can cause pressure on soft tissue instead of your sit bones.

Fix:

Measure your sit bone width

Choose a saddle designed for your riding style (road, gravel, commuting)

Test different shapes (flat vs curved)

2. Poor Bike Fit

Even the best saddle won’t help if your bike fit is wrong.

A saddle that’s too high or too low can:

Increase pressure on sensitive areas

Causes excessive movement and friction

Fix:

Adjust saddle height so your knee has a slight bend at the bottom of the pedal stroke.

Ensure the saddle is level (not tilted too far up or down)

3. Lack of Padded Shorts

Regular clothing isn’t designed for cycling.

Without padding, friction and pressure increase significantly.

Fix:

Invest in quality padded cycling shorts (chamois)

Avoid wearing underwear underneath

4. Riding Position and Technique

Sitting heavily on the saddle for long periods can increase discomfort.

Fix:

Shift positions occasionally

Stand on the pedals during longer rides

Engage your core to reduce pressure on the saddle

5. New Rider Adjustment Period

If you’re new to cycling, soreness is normal.

Your body needs time to adapt.

Fix:

Start with shorter rides

Gradually increase duration

Give your body time to adjust

Conclusion

Saddle pain doesn’t have to ruin your rides. With the right saddle, proper bike fit, and good riding habits, you can eliminate discomfort and enjoy cycling again.
