Do bikes with disc brakes have quick release?

If you have rim brakes, you will have a quick release skewer. If you have disc brakes you will most likely have thru axle skewers. If you have a disc brake older than 2019, you may have a quick release skewer, but disc brake road bikes made today are generally thru axle.

Can you change a bike wheel to quick release?

What you want to do is turn your wheel into a quick-release wheel. In order to do this, you need to remove that solid, bolt-on axle and the parts on it, and replace them with a quick-release compatible axle and parts (called a quick-release axle set).

Why is quick release bad?

Incorrect quick-release use is dangerous because these mechanisms hold the wheels in place. The most common mistake is simply turning the lever like a wing nut until the wheel seems tight. Used this way the lever and wheel can loosen as you ride and can come off unexpectedly.

Are all disc brake bikes thru axle?

That means that thru-axles work well for disc brakes and is the main reason you’ll find them on the majority of disc-brake road bikes. At the front, road bike thru-axles are now pretty much standardised at 100mm long by 12mm wide (although some early thru-axle road bikes had 15mm diameter thru-axles).
