Just got my first electric longboard, V2, with 300 miles, $300 out the door with remote and chargers. It's a dual plus and XR.
Came factory stock minus the bash guards front and rear. Rode terrible, really loud, vibrations, something jittering around in the back like aluminum.
Swapped over my 85mm caguamas from another board, as well as bones swiss ceramics, titanium spacers, riptide WFB chubby 68a bushings. Rolls like my landyachtz evo 40 now, nice and quiet, just not as heavy. I don't go fast, so the soft bushings work for me.
Have riptide 90a pivot cups, acer 6903 ceramic pulley bearings, and kevlar belts coming in the mail soon. After that, planning on switching to aluminum 75T wheel pulleys with 105 dad bods, and titanium motor pulleys. Overall, with the board and parts, should run me $1,000.
