Here's a suggesion, let's use the "Malls & Marons" rules:
Inline Skates
These pair of boots have wheels affixed to their soles. When worn, the characters speed
increases by +10, and he receives +2 dodge bonus to his Defense if he all he does during
his round is move double his speed or more.
Skateboard
This popular mode of transportation among teenagers is mainly a board with four wheels
affixed to each corner. When rode, the character's speed increases by +10, and he
receives +2 dodge bonus to his Defense if he all he does during his round is move double
his speed or more. But, unlike inline skates, the skateboard can be used as a weapon
(when not being rode). Though it is medium-sized, the skateboard must be used with two
hands to be an effective weapon.
