In this step-by-step video, I show you how to convert your Razor MX350 or MX400 electric dirt bike from the stock 24V battery setup to a powerful 36V lithium battery upgrade. This “overvolt” modification boosts the bike’s top speed from around 12 mph to an impressive 23 mph and provide twice the range—using the original motor!
Along with the battery upgrade, I also install hydraulic disc brakes for better stopping power, custom graphic decals for a sleek new look, and LED lights for added visibility and style.
