Bộ phát âm thanh kiểu Chopper cho xe đạp điện

Back in the Day's young boy's would tape playing card's to the fork's of their bike's and it would sound like a harley davidson motorcycle when riding down the street. Well, this is the 2026 version of that idea.

Get zip ties and mount the card holders on Both forks, insert the cards into the slots FULLY (you may need to use a credit card or butter knife to clean out the slot first). then Ride Free and Loud! 

REFILL cards are a separate file, also available here.  

Quet Ebike? Not Anymore Baby. Have Fun!
