MILWAUKEE — May 24, 2022 — Today Serial 1 launched BASH/MTN, the second offering from its Select Series—limited-edition, special-production versions of the company’s standard eBikes that have been elevated with premium finishes, added technology, and unmatched attention to detail. (The first Select Series offering was the white-tired MOSH/TRIBUTE that sold out almost immediately.) The BASH/MTN build will number just 1050 units: 525 for the United States and 525 for Europe.

“Less is more,” said Aaron Frank, Brand Director at Serial 1. “That’s the promise of BASH/MTN. No fussy suspension to tune, no finicky drivetrain to adjust—just two wheels, one gear, and one purpose, to provide the most direct connection between you and the trail. The less you worry about managing and maintaining technology, the more you can focus on enjoying every ride.”

BASH/MTN takes the minimalism of the mega-popular MOSH/CTY and adapts it for off-road adventure with grippy, high-volume Michelin E-Wild knobby tires, a shock-absorbing SR Suntour NCX suspension seat post, and extra-powerful, four-piston TRP hydraulic disc brakes. Everything you love about the MOSH/CTY is maintained—including the immediate feedback that only comes from a rigid frame and the instant acceleration that the single-speed drivetrain delivers—all presented with the clean, uncluttered style that you have come to expect from Serial 1.

Under Yucca Tan paint with Gloss Graffiti graphics, BASH/MTN incorporates a maintenance-free Gates Carbon Drive belt, a mid-mounted Brose S Mag motor that makes 90Nm of knee-saving torque and integrated lighting. Like all 2022 Serial 1 eBikes, the BASH/MTN is compatible with the Serial 1 App, developed in partnership with Google Cloud to capture essential ride data and improve security and safety, so you can just enjoy every ride.

About Twotone Amsterdam

The roots of Twotone go back in 2007, when Twotone’s founder – Jon Woodroof – cofounded a fixed-gear focused bike shop in Atlanta, GA named No Brakes. His clothes nearly always matched his track bike & he earned the nickname Twotone. Jon cut his teeth on promoting his own shop, the brands they sold, and even suppliers, athletes, and other organisations they partnered with all before Instagram!

Those entrepreneurial roots grew into the hold your line, you'll be fine full-send approach to how we run our business today. A 10-year-old nickname became a Dutch BV in 2014 & Twotone has become THE one-stop-shop for cycling-savvy sales, marketing, and PR across Europe in the USA.
