> He uses a skateboard and grappling hooks to get around and has samurai swords because he studies the way of the blade.
It's been a minute, but I think Hiro Protagonist gets around on a motorcycle with wheels that deform to adapt to the terrain.
The story does have couriers that use skateboards and grappling hooks, though.
The super bike is later in the book and temporary. When delivering pizzas he has a car so cool and intimidating it makes other drivers get out of the way so he can deliver pizza faster. But he actually wrecks it and looses the delivery job near the start of the book. For most of the story he doesn't have any iconic means of transportation.
