“The bike’s gestalt is defined by the lack of bodywork,” says Walt, “which was important to me. It was a win-win, because there was no bodywork needed to define its shape, and it saved weight. When I weighed the bike before paint, it was just 100 pounds [45 kg].”
At the core of WSM’s svelte speedster is a 3000W Sur-Ron motor, supplied by the e-bike company Luna Cycle. It’s hooked up to a 65 volt Panasonic battery pack, and controlled by a sine-wave controller that WSM programmed. The wiring harness is custom and uses Luna Cycle parts, and the gear reduction and final drive systems are belt-driven.

Up front is a set of shortened DNM forks with upgraded internals, held in place by WSM yokes. There’s a DNM rear shock, and the linkages, swingarm and disc brake set are all Sur-Ron parts. WSM boxed the swingarm in aluminum, and installed a pair of 19” Segway wheels, with aluminum discs at the back.
