A splinterbike is a special kind of bicycle that is made entirely out of wood, like the kind of wood that comes from trees. It's called a "splinterbike" because the wood is cut into little pieces, or "splinters," and then put back together to form the bike.
The person who rides the splinterbike has to sit on a wooden seat and use wooden pedals to make the bike go. The wheels are also made of wood, and can sometimes be really big or really small depending on the kind of splinterbike you have.
Splinterbikes are special because they are very unique and not many people have them. They are also very eco-friendly, which means they are good for the environment because they don't use any electricity or gas to make them go. Instead, they rely on the power of your legs to move them forward.
Riding a splinterbike can be a lot of fun, but it can also be hard work because you have to pedal really fast to go fast. It's kind of like riding a regular bike, but it feels a bit different because the wood makes it a bit heavier and sturdier.
Overall, a splinterbike is a very cool and different kind of bike that is made out of wood. It's good for the environment and can be a lot of fun to ride, but it also takes some work to make it go.
