Answer:
Unless you get something caught in the wheel, spokes usually snap because of (metal) fatigue rather than overload. Fatigue is something that can set in when a part sees a load that comes and goes over and over again. And that's what happen to every spoke in a bicycle wheel every time it passes between the hub and the ground.
The way to avoid this is to have the spokes decently tight. With tighter spokes, the (proportional) change in tension that happens when the spokes pass between hub and ground gets smaller, which keeps fatigue from setting in. For front wheels and single-speed and internally geared hubs it's usually not a problem. But bikes with external gears can't use the same spoke tension left and righ on the rear wheels, which make them particularly prone to fatigue.
Trouble is, if your spokes were under tensioned from the start, then they've all collected fatigue, so once they start popping, they'll keep popping. No fix for it apart from replacing them all, or getting a new wheel, making sure it's properly tensioned before you start riding it.
Sometimes, if your bike gets exposed to certain chemicals, it can cause embrittlement. And sometimes you do get a bad batch of spokes, but poor tension is the far most usual culprit.
If they're snapping at the spoke hole at the hub, maybe the problem is there.
J-bend spokes needs to have as much as possible of the bent section supported by the hub flange. If the bent section of the spoke is longer than usual, or if the hub flange is thinner than usual, the bent section won't be properly supported. It'll flex and fail.
Hubs are typically drilled with counter-sunk holes to accomodate the spoke head. If the wheel was built with the spokes all one hole off, the heads would pop off from the sharp edge of the spoke hole in the hub flange.
This is true with many rims too. Spoke holes are often staggered to be closer to the hub flange the spoke is coming from. If the spokes are one hole off, the odd angle of the spoke nipple can introduce stress and break the spoke.

What should I do if I have broken spokes on my bike?
If you have broken spokes on your bike, it is best to take it to a bike shop for repair. Riding with broken spokes can cause further damage to your wheel and potentially lead to a dangerous situation. It is important to have a professional assess the damage and replace the broken spokes to ensure the safety and functionality of your bike.
What should I do if my bicycle has busted spokes?
If your bicycle has busted spokes, you should take it to a bike repair shop to have the spokes replaced. Riding a bike with busted spokes can be dangerous and may cause further damage to the wheel.
How many spokes are typically found on a standard bike wheel?
A standard bike wheel typically has 32 or 36 spokes.
What are the different types of spokes used in a bike wheel and how do they affect the overall performance of the bike?
There are mainly two types of spokes used in bike wheels: straight-pull spokes and J-bend spokes. Straight-pull spokes are more aerodynamic and can provide better stiffness, while J-bend spokes are more common and easier to replace. The type of spokes used can affect the overall performance of the bike by influencing factors such as weight, aerodynamics, stiffness, and durability of the wheel.
Is it bad if you have rusty spokes on your bike?
A little isn't much to worry about, but if they keep rusting they can eventually snap off.
An old fashioned bike wheel has 21 spokes How many spaces are between the spokes?
A wheel with 10 spokes will have 10 spaces between the spokes.
How many spokes are typically found in a standard 26-inch bike wheel?
A standard 26-inch bike wheel typically has 36 spokes.
How do you put spokes on a bike rim?
To put spokes on a bike rim, start by inserting the spokes into the hub holes. Then, thread the spokes through the rim holes and tighten the nipples to secure them in place. Repeat this process for all the spokes until the wheel is fully laced. Finally, adjust the tension of the spokes to ensure the wheel is true and balanced.
What are the most common materials used for manufacturing bike spokes?
The most common materials used for manufacturing bike spokes are stainless steel, aluminum, and titanium.

How can I create a nostalgic sound effect using tennis balls in bike spokes?
To create a nostalgic sound effect using tennis balls in bike spokes, simply attach the tennis balls to the spokes with zip ties or tape. As the bike moves, the balls will hit against the spokes, creating a rhythmic and nostalgic sound reminiscent of childhood days.
What are the different types of spokes used in bike wheels and how do they affect the performance of the bike?
There are mainly three types of spokes used in bike wheels: straight gauge, butted, and bladed. Straight gauge spokes are the most basic and durable, but heavier. Butted spokes are lighter and more flexible, providing a smoother ride. Bladed spokes are aerodynamic and reduce wind resistance, improving speed. The type of spoke used can affect the overall performance of the bike in terms of weight, flexibility, aerodynamics, and durability.
