Hello all, I'm RolluS (real name Reynald), 35y.o from Paris,France. I've bought a single wheel skateboard from an aliexpress seller some times ago: It's basically a unicycle, but with a board instead of pedals, the riding position is like a snowboard. This thing has a 500W 10" wheel, a 132Wh 60V Li-Ion battery, and a MicroWorks 30B controller. Max speed 25km/h, range 5-10km. I was a little disappointed with the range, so I'm heavilly modding it to allow LiPo installatio
