Max. Minimalism: Walt Siegl’s new electrical bike idea




The sector of electrical bikes is, in some ways, mute discovering its ft. With stout-blown electrical bikes at one shatter of the spectrum and pedal-lend a hand bicycles on the completely different, there’s an enormous heart flooring the place creativeness can flee wild. And that’s exactly the place Walt Siegl has carried out together with his newest customized.

Constructed absolutely from the ground up, this modern WSM creation is extraordinarily not simple to pigeonhole—and that’s exactly how Walt supposed it. “I wanted to acquire a machine that appears treasure it comes from the bigger two-wheeled world, and never most gripping the bike world,” he says. “From track bicycles and mopeds, besides to efficiency bikes.”




“As a result of my compose platform is a mixture of all these worlds, this bike might presumably moreover with out effort be the platform for a pedal-lend a hand bike, a moped, or for an electrical efficiency bike. Electrical bike expertise lends itself to this versatility.”

“I wanted a crisp and good-looking compose, and the appears of a perception bike, whereas mute displaying my handiwork and the love that went into constructing it.”




This isn’t the precept time Walt’s labored with an electrical powertrain—his Alta-powered PACT is certainly one of probably essentially the most alluring battery-powered two-wheelers we’ve considered. However that was as soon as very nice a ‘bike,’ and Walt wished to shatter one factor stunning this time. Creativity was as soon as paramount, because the problem was as soon as commissioned by the Haas Moto Museum in Dallas, Texas.

“As quickly as we talked concerning the problem,” says Walt, “Bobby Haas, the museum founder, and director Stacey Mayfield had been in stout give a improve to of my alive to passion in constructing one different electrical bike. Bobby is a tall patron of customized bike builders (he has three of mine), and likewise continues to perform each bike that’s indubitably related throughout the historical past of two-wheeled transportation. The museum is a must-search the recommendation of with.”




Walt wished to acquire the lightest and strongest chassis that it’s most definitely you may presumably be able to think about, so he opted for a monocoque compose with puny or no further bodywork. The compose was as soon as sketched out first, then a body was as soon as constructed out of welding wire, and coated in paper to hone in on the ultimate compose.

Subsequent up, Walt constructed a jig to originate the skeleton from skinny-walled, puny diameter chromoly tubing. Metal reinforcements had been welded into the guidance neck and rear suspension pivot elements, and aluminum inserts added as mounting elements. Then the full element was as soon as wrapped in carbon fiber, and carried out with resin.




Up excessive is an Alcantara seat, constructed on a thin sheet of polyurethane on a carbon fiber seat pan. Factual throughout the abet of it’s miles a mini tail ‘loop’ that was as soon as on the start supposed as a sort out to lag the bike spherical, nevertheless ended up being a compose attribute. The concept that’s echoed further ahead, the place a cutout throughout the chassis offers procure admission to to the battery’s digital functionality present camouflage.

The sterling different ‘bodywork’ is a pair of battery covers, welded up from skinny aluminum types, and mounted with quarter-flip fasteners.




“The bike’s gestalt is printed by the dearth of bodywork,” says Walt, “which was as soon as well-known to me. It was as soon as a bear-bear, as a result of there was as soon as no bodywork wished to interpret its form, and it saved weight. After I weighed the bike earlier than paint, it was as soon as comely 100 kilos [45 kg].”

On the core of WSM’s svelte speedster is a 3000W Sur-Ron motor, geared up by the e-bike agency Luna Cycle. It’s zigzag as much as a 65 volt Panasonic battery pack, and managed by a sine-wave controller that WSM programmed. The wiring harness is customized and makes train of Luna Cycle elements, and the gear discount and ultimate stress programs are belt-driven.




Up entrance is a location of shortened DNM forks with upgraded internals, held in do by WSM yokes. There’s a DNM rear shock, and the linkages, swingarm and disc brake location are all Sur-Ron elements. WSM boxed the swingarm in aluminum, and put in a pair of 19” Segway wheels, with aluminum discs on the abet.

Up throughout the cockpit you’ll obtain LSL clip-on clamps with customized bars and bar-ends, Sur-Ron controls and a Segway speedo. And never using a take cling of or gear shifter, all that’s occurring decrease down is a good-looking location of foot pegs—and a puny quilt to protect the motor’s wiring. And that’s it; there’s puny or no else on this sharp machine to distract the peep.




We requested Walt if he intends to acquire extra of those. However he replied that as a result of it’s for the museum’s customized bike piece, it’ll stay a one-off—and extra’s the pity.

Now not decrease than he’s not throwing all of the next ideas out the window… “My subsequent e-bike problem can comprise some elements of this bike for certain. The flexibility of the platform is what I’m drawn to.”
