About Us

Radmoto is an electric powersports dealership and service center based in Portsmouth, New Hampshire, serving riders across New England. We offer electric dirt bikes, e-bikes, mopeds, scooters, parts, and upgrades—with hands-on guidance to help customers choose the right ride.

Who We Are

Founded by mechanical engineer Charles “Chas” Sullivan alongside his father, Jeff, Radmoto grew from a shared love of motorcycles and working on bikes. Today, our team combines that mechanical experience with a focus on electric powersports, helping customers buy, maintain, and customize their machines.
