SRPNT MX Electric Dirt Bike by Throne | Small Motocross E-Moto

 

The little brother to the SRPNT X3, X8, and Z27, the SRPNT MX brings a 10kW mid-mounted motor, a 72V battery with Samsung cells, and a 17-inch front / 14-inch rear wheel setup to the dirt. With a listed top speed of 60 mph and High, Drive, Eco, and Reverse modes, it gives riders several ways to manage power, whether picking through a tight section or opening things up on suitable terrain.

The chassis and swingarm use 6061 T4&T6 aluminum, with chassis construction forged under 3,000 tons of pressure and finished in baked paint. Up front, an inverted suspension fork provides 240mm of travel to absorb trail impacts. A KKE rear suspension link system handles the back end, while 295mm of ground clearance gives the bike room to clear uneven terrain and trail obstacles.

A 790mm seat height and 1,170mm wheelbase help define the MX's smaller platform within the SRPNT lineup. The mid-mounted motor keeps its weight near the center of the bike, and the 428 drive chain transfers power through a 13:48 gear ratio. Reverse is a useful addition when backing out of a tight spot.

NOTICE: Some vehicles include a “City Mode” that limits top speed to 20 mph, making them compliant with many city and state regulations for use on public roads, bike paths, sidewalks, and parks. Other vehicles may feature an “Off-Road” or “Race” mode, which increases performance and top speed (more than 20mph) but may render the vehicle illegal for use in the city or on public roadways. Vehicles without a “City Mode” and exceed a top speed of 20mph are not for use on public roads, bike paths, sidewalks or in parks, and are intended for off-road, privately owned land or track use only. Always check and follow your local laws and regulations before riding
