Riding a skateboard with 2 wheels, also known as a caster board or ripstik, involves a different technique than riding a traditional skateboard. To ride a caster board, you place one foot on each deck and use a twisting motion of your hips and legs to propel yourself forward. You can also use your body to steer and carve, similar to snowboarding. It may take some practice to get the hang of riding a caster board, but once you get the hang of it, it can be a fun and unique way to ride. **

Yes, 80a wheels are suitable for outdoor use. The 80a durometer rating indicates that the wheels are softer, which helps absorb shocks and vibrations from rough outdoor surfaces. This makes them ideal for cruising, commuting, and general outdoor skating activities. The softer wheels provide a smoother ride and better grip on uneven terrain compared to harder wheels. **

On a typical car, there are four wheels that have brakes. Each wheel is equipped with its own brake system to help slow down or stop the vehicle. This design ensures that the car can come to a safe and controlled stop, distributing the braking force evenly across all four wheels. **

"Search dog 2?" is likely a reference to a specific search and rescue dog that is part of a team. In search and rescue operations, dogs are trained to locate missing persons or individuals in distress. The term "Search dog 2" could be a way to identify a particular dog within a team of search dogs. **

It is generally not recommended for children to go to the playground alone with a dog. Even if the dog is well-behaved, there are potential risks involved, such as the dog getting into a fight with another dog, running off, or not being properly supervised around other children. It is important for children to have adult supervision when interacting with animals, especially in public places like playgrounds. **

The choice between 80mm and 100mm wheels depends on the specific use and preference of the skater. 80mm wheels are generally better for maneuverability and agility, making them suitable for tricks and urban skating. On the other hand, 100mm wheels are better for speed and stability, making them ideal for long-distance skating and cruising. Ultimately, the better option will depend on the skater's skating style and the type of terrain they will be skating on. **

Aluminum wheels are generally more expensive than steel wheels. This is because aluminum is a lighter and more durable material, which makes it more desirable for high-performance and luxury vehicles. Steel wheels, on the other hand, are more affordable and commonly used in economy cars and trucks. The cost difference between the two types of wheels can vary depending on the specific design, size, and brand. **

No, you cannot replace longboard wheels with skateboard wheels. Longboard wheels are typically larger and softer than skateboard wheels, allowing for a smoother ride and better stability at higher speeds. Skateboard wheels are smaller and harder, designed for tricks and maneuvers that require more precision and control. Using skateboard wheels on a longboard could result in a less comfortable and less stable ride. **
