When it comes to holding your bike up without a stand, there are a few options to consider.
One of the simplest ways to hold your bike up is to lean it against a wall, tree, or other solid object. This can be a convenient and stable way to park your bike, but it's important to make sure that the surface you're leaning your bike against is clean and free of obstacles that could damage your bike.
Another option is to use a bike rack. Bike racks come in a variety of designs, and they can be a convenient and stable way to park your bike. Some bike racks are designed to be attached to a wall or other solid object, while others are designed to be freestanding.
You can also use a bike lock to keep your bike upright. A bike lock can be used to secure your bike to a solid object, such as a lamp post or a tree, and it can be used to keep your bike upright while you take a break.
Finally, you can use a bike stand. Bike stands come in a variety of designs and can be a convenient and stable way to park your bike, but they can be more expensive than other options.
When it comes to why kickstands are on the left, it is because traditionally, the left side of the bike is the non-drive side. This means that the left side of the bike does not have any moving parts and is less likely to get damaged when a kickstand is in use. Additionally, having the kickstand on the left side allows the rider to easily access the kickstand with their left foot, making it easier to use.
In conclusion, there are several ways to hold your bike up without a stand, such as leaning it against a wall, tree, or other solid object, using a bike rack, using a bike lock, and using a bike stand. Kickstands are traditionally on the left side of the bike because the left side of the bike is the non-drive side and it is less likely to get damaged when a kickstand is in use, it also allows the rider to easily access the kickstand with their left foot. It is important to remember that the safety and stability of the bike should always be considered when parking it.
