Rules

Bikes will be judged King of the Hill style. Two bikes battle, Best Sounding Bike stays until all have

played. Playing order will be randomly drawn. So you should have a playlist of a ton of songs because

you never know how many times you will have to battle. Make sure your battery is charged.

If you arrive after the bikes have been randomly drawn, but the contest has not started and you still want to compete,

you automatically go first.
All bikes must be ridden in to the arena unless location does not allow riding inside of indoor arena.

There will be up to 6 classes judged at this time.

If the speaker is on the bike it counts, whether it’s hooked up or not.

Please make sure you have your phone on airplane mode so we don't get really loud phone ringing in the middle of your turn

Only adjustments that can be made during your time is volume and bass knob

Be ready to go. Have your song selection ready. Have your phone ready.

Contestants will each have one 2 minute round to show what you got. Judges, at their discretion, may decide that they want to hear some bikes again to determine winner of each round.

Tour Pack speakers are allowed and will count towards speaker count.

Compression Drivers, Midrange, Mid Bass and Subwoofers are all counted as speakers

Small Tweeters or horns like ST25, ST35,  etc... do not count as speakers

Coaxial speakers with horns or tweeters will count as one speaker.
