The battery life of a fat tire electric bike will depend on the specific model and its components. Generally speaking, fat tire electric bikes have larger batteries than traditional electric bikes, which allows for longer rides between charges. However, factors such as rider weight, terrain, and riding style will also affect battery life. Many high-end fat tire electric bikes can last for up to 50 miles (80 km) on a single charge, but some can go even further. For instance, the Mihogo LX, with its dual 48V 28.8Ah battery system packing 1.4kWh of energy, lasts for up to 86 miles (138km) per charge.
