This monstrosity weighs 120 pounds, but I have a 48 tooth gear in the front, and a 16 tooth in the back, next upgrade needs to be a internal three speed hub, usually am going at 18mph on average. The bike is might be a J. C. Higgins Freightliner, early '60s, but nobody knows. Everything sits on 1" thick solid wood, except for the speakers, 5/8" plywood. Switches go to the Bluetooth receiver, 9 band equalizer, sub amp, speaker amp, and tail light, there is a button on the handlebars for the horn, and a turn signal switch below the handle bars. The unit top right is a Bluetooth receiver, the black box is a nine band equalizer. Far board is a 600 watt amp for the sub, near board is a 2X100 watt amp for the speakers. These are Boss Audio 6X9 Onyx NX694 800 watts per pair. This is a Boss Audio 12" Phantom P126DVC dual voice coil wired to run at 1 ohm, max power 2300 watts.
