hi i'm alex and i just moved from cuba around 6 months ago to California, and back in cuba, we have these bikes called Riquimbilis, which were fast little creations of ours. when i got here to the states, i noticed online that here there are these kits to build a motorized bike. we brought my old Riquimbili here, but my uncle bought me a beach cruiser and i would like to know which kit would be good for one
