Here are a bunch of cycle / arrow clip art for you to use both commercial and personally. This set contains 36 arrow images. There are 3 different arrow types each with 6, 5, 4, and 3 arrows. Each of those sets come in black, white and outlined. These arrows were created so if you have a circle, they will fit the outline of the circle.
Tip: If you need a different amount of arrows, you can always just draw a box over some of the arrows to cover them up in like Word or Powerpoint.
