Monster

The Monster is the iconic very-large-wheel electric unicycle (EUC) from Gotway, the Chinese maker later rebranded as Begode. Its defining feature is a 22-inch pneumatic wheel — far larger than the 14- to 18-inch wheels typical of other EUCs — which for years made it the biggest production unicycle available. It runs an 84 V battery system (a 100 V variant was offered later) with a high-capacity pack, most commonly cited at 2,400 Wh using Panasonic cells, paired with a single hub motor rated around 1,600 W (roughly 2,400 W peak; later V3 builds stepped the motor up). The large diameter gives the Monster an exceptionally smooth, stable ride and the ability to roll over bumps, trail debris and rough surfaces with little disturbance, which is why it is prized as a long-distance and light off-road cruiser. The trade-offs are size and practicality: it is tall, heavy (around 29-33 kg depending on battery), slow to charge (roughly 18-20 hours on the standard charger), and clumsy in tight urban spaces. Manufacturer top speed is quoted near 40-50 km/h, with riders reporting figures up to about 55 km/h, and the big pack enables very long range — up to roughly 220 km in ideal conditions for the 2,400 Wh model. It has no suspension; the comfort comes entirely from the oversized tire.
