It's usually not a problem. They're threaded (the left has a reverse thread) so that normal pedalling action tightens them down as you go. Lube the threads, install with moderate torque and you should be good to go.

Cranks can, and do come loose occasionally. The cranks being aluminum and the axle being steel usually means that the cranks gets badly damaged unless you get it fixed immediately, as it's pretty close to impossible to get a damaged crank properly seated again. To avoid this, grease all the parts and reassemble with the correct (high) torque.

BeauDepends a bit on what kind of axle you've got. If it's a nutted axle(as opposed to a q/r axle) it's usually enough just to tighten the axle nuts a bit harder. You might want to make sure that all the paint is removed from the contact surface of the dropout first. You can check that the locknuts on the axle are serrated/knurled on the side that face the locknut, and you can also get axle nuts that are serrated/knurled too. If that doesn't help then you'll have to get some chain tensioners.
Do note that a chain only has to be tight enough not to slap around too much, you don't want to tension it like a string.

Why is it important to adjust a bike chain that is too loose?
It is important to adjust a loose bike chain because it can cause the chain to slip off the gears, leading to potential accidents and damage to the bike. A loose chain can also affect the bike's performance and efficiency.
Why is it important to fix a loose bike chain promptly to prevent damage to the bike?
It is important to fix a loose bike chain promptly to prevent damage to the bike because a loose chain can cause the chain to slip off the gears, leading to potential damage to the bike's drivetrain components and affecting the bike's performance.
Why does the bike chain become loose when not pedaling?
The bike chain becomes loose when not pedaling because the tension in the chain is maintained by the force applied when pedaling. When you stop pedaling, there is no longer tension in the chain, causing it to become loose.
What is the purpose of a bike chain tensioner and how does it help maintain the proper tension in the bike chain?
A bike chain tensioner is a device that helps maintain the proper tension in the bike chain. It is used to prevent the chain from becoming loose or falling off the gears while riding. The tensioner works by adjusting the position of the rear derailleur, which in turn keeps the chain at the correct tension for smooth and efficient pedaling.
How can I fix a loose bike chain?
To fix a loose bike chain, you can adjust the tension by loosening the rear wheel and pulling it back to tighten the chain. Make sure the chain is properly aligned with the gears and then tighten the rear wheel back in place. Check the chain tension by lifting the bike and spinning the pedals to ensure it is not too tight or too loose.
How can I effectively address the issue of a bike chain that keeps falling off?
To effectively address the issue of a bike chain that keeps falling off, you can try the following steps: Check the chain tension: Make sure the chain is not too loose or too tight. Inspect the chain and sprockets for wear: Replace any worn-out parts. Clean and lubricate the chain regularly: This helps prevent it from slipping off. Ensure the chain is properly aligned: Adjust the derailleur if necessary. Consider replacing the chain if it is old or damaged. By following these steps, you can help prevent your bike chain from falling off frequently.
What causes a bike chain to slip while riding?
A bike chain can slip while riding due to issues such as a worn chain, misaligned gears, or a loose chain tension.
How can I fix a loose chain on a bike?
To fix a loose chain on a bike, you can adjust the tension by either loosening the rear wheel and pulling it back to tighten the chain, or by using a chain tool to remove links and shorten the chain. Make sure the chain is properly aligned and lubricated before riding.
Can you help me fix my chain that keeps coming off my bike?
To fix a bike chain that keeps coming off, you may need to adjust the tension or alignment of the chain. Check if the chain is properly lubricated and if the gears are shifting smoothly. If the problem persists, consider taking your bike to a professional for further inspection and repair.
Why is it important to regularly check and tighten a bike chain when it becomes loose?
Regularly checking and tightening a bike chain is important to ensure smooth and efficient cycling. A loose chain can slip off the gears, causing the bike to malfunction and potentially leading to accidents. Tightening the chain helps maintain proper tension and prevents wear and tear on the bike's components.
What are the benefits of using a chain guard on a bicycle?
A chain guard on a bicycle helps to protect the rider's clothing from getting caught in the chain and getting dirty or torn. It also helps to prevent the chain from getting rusted or damaged, which can improve the overall performance and longevity of the bike. Additionally, a chain guard can enhance the safety of the rider by reducing the risk of accidents caused by loose clothing getting caught in the chain.
Why is my bike chain loose and how can I tighten it?
Your bike chain may be loose due to wear and tear or improper installation. To tighten it, you can adjust the tension by moving the rear wheel back in the dropouts or using a chain tensioner tool. Be sure to check the chain for wear and replace it if necessary.
