Greetings... I got 4 ebikes in an estate distribution in various levels of disrepair. Do you guys work on: Aostirmotor S18 Snakeskin; Juiced Hyper Scrambler 2 Dual Battery; Say Yeah M3 Lowboy; or Paselec GS9 bikes? Biggest issue is the M3 Lowboy, cuts off all electric under any load. Resets with battery unplug/plugin... I'm in Durham and can trailer bikes to you for diagnostics if you work on them, Thanks
