This is the 52 volt, 19.2 Ah model Juiced Rip Current S, size medium, Class 3 e-bike. Comes with 2 brand new Ortlieb waterproof pannier bags and a few extra inner tubes. Bafang motor with torque sensor, Shimano Altus shifter, disc brakes, after market Spank Spike vibrocore handlebar, extra LED light. 26" x 4" Origin8 Supercell tires. Nothing wrong with this electric bike. Goes 28 mph, I think it can go higher if you unlock race mode.
