SRPNT is an electric dirt bike brand sold by Throne Cycles, a bike company in South El Monte, California. Throne began with classic track bikes and now also makes big-wheel BMX bikes and e-bikes.
The first SRPNT, a 72-volt, 10,000-watt e-dirt bike, went on sale in 2024. The 13,000-watt X3 followed in 2025. In 2026 SRPNT added two larger bikes on a forged aluminum chassis: the X8, with an 18KW motor, and the Z27, with a 27KW motor and an 80 mph listed top speed.
SRPNT bikes are built for off-road and private-property riding and are not street legal.
