"Ah" gives no indication as to the capacity of the battery. That would instead be provided by "Wh". This is because ebikes commonly have 3 different voltages, 36v, 48v, and 52v.
The X20 has debuted as PVY's first-ever dual-battery e-bike, and as such is touted to keep going for about 200 kilometers (km, or ~124 miles) per charge. Its moped-style frame is equipped with fat tires, a torque sensor and a motor rated for a 1,000W peak mode. It is available to order at €100 off its retail price.
