Earlier today, Serial 1 unveiled its first-ever regular production e-mountain bike. Called the SWITCH/MTN, the new bike is built on the same aluminum frame that underpins the excellent RUSH/CTY SPEED urban adventure bikes … but that’s about where the similarities end.
For starters, Serial 1 says its new eMTB is, “extremely off-road capable,” and it’s backing up those claims with SR Suntour’s premier ZERON35 BOOST AIR fully adjustable front fork suspension, a TranzX dropper seat, and high-volume (read: thicc) Michelin E-Wild knobby tires for excellent all-surface traction. Drivetrain components come from SRAM’s SX Eagle line-up, including a 1×12 gearing combination controlled with E-bike-specific trigger shifters, while braking is handled by a set of oversized TRP Slate T4 hydraulic disc brakes with four-piston calipers designed for fade-free performance, even on the super-fast, e-powered descents this bike is capable of. (Wear a helmet, kids!)
There are four specially tailored ride modes and a “walk assist” mode to help ensure that riders of all fitness levels will be able to get the most out of the new Serial 1 eMTB— and a maintenance-free Gates belt drive should help keep downtime to a minimum.
This Seems Pretty Familiar

If you find yourself wondering if you’ve read this before– you kind of have! A few weeks ago, Serial 1 revealed the ultra limited edition BASH/MTN (shown, above) which featured off-road tires and a shock-absorbing seat post. That bike was more about light city trails and uneven pavement, however. The SWITCH/MTN, in contrast, has a front fork suspension, upgraded brakes, and more to give it more off-road capability than you might expect from the more urban-focused BASH.
I, for one, would rather have the fixed fork, Harley-inspired BASH/MTN, but the closest I come to trail riding these days is checking out the fancy pictures Serial 1 sends me. If I were someone more likely to get covered in mud than run over by a Honda Pilot being driven by someone taking selfies from the drivers’ seat, I’d be really psyched by the added off-road bits. And, while I almost didn’t write that last bit to keep from further upsetting my friends at the Harley bike brand, it’s not like “this is a great mountain bike for people who like mountain bikes” isn’t a solid endorsement. you know?
Check out the specs and pictures, below, call your local Harley-Davidson dealer to arrange a test ride, then let us know what you think of Milwaukee’s latest electrified two-wheeler in the comments section at the bottom of the page.

I don't like paywalls. You don't like paywalls. Who likes paywalls? Here at CleanTechnica, we implemented a limited paywall for a while, but it always felt wrong — and it was always tough to decide what we should put behind there.
