Why eat ramen noodles
Why not?

Riding a bicycle is kind of cool if you're not a ninja. You can ride everywhere, alone or with friends, you can ride in town or even outside that same town. Some people like to have a flower basket in front and others like to have a bell, a very cool bell for that matter. Riding a bike is so cool and you can even say bike instead of bicycle!

But wait!

That's not ninja stuff! Ninja are stealthy, move fast and are fighting machines, they need more action (But they like to have a bell to warn the poor bad guys that their end is coming). So that's why ninjas need more challenge and they love to eat their ramen with chopsticks while riding a bicycle and still being as awesome as possible.
