Harley Davidson's e-bike spin-off brand Serial 1 has launched the limited-run BASH/MTN, a single-speed electric mountain bike focused on offering a simple riding experience.

The new machine is a single-speed eMTB that is designed to offer minimal complexity. It is the second model in Serial 1's Select Series line-up and will be limited to 1050 units, which will be split evenly between the US and European markets.

Serial 1 (random trivia: the firm is named after the first motorbike produced by Harley Davidson) says the machine was inspired by a company engineer's personal build. Brand chief Aaron Frank said it has "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 BASH/MTN is effectively a reworked version of the Serial 1 MOSH/CTY, and includes the mid-mounted Brose S Mag motor, Gates Carbon Drive belt and lightweight aluminium frame of that model. It also features integrate lighting and the new Google Cloud connected features recently added by Serial 1.

But there have been a number of adjustments to turn the machine into an off-road e-MTB. They include four-piston 203mm hydraulic disc brakes, Michelin E-Wild off-road tyres, an SR Suntour NCX suspension seat post that offers 50mm of travel and a new finish with Yucca Tan paint and special graffiti graphics.

The Brose motor offers 66lb ft of torque, and four ride modes ranging from Eco to boost, along with a walk assist function to help when pushing the e-bike. In Europe the maximum assistance speed will be set to 15.5mph to meet pedal-assist e-bike rules, while US models will provide power up to 20mph.

There is a 529Wh lithium-ion battery, which is built low into the frame to lower the centre of gravity, that offers a range of 30-95 miles depending on mode and terrain. Serial 1 claims a 0-75% charge will take 2.6 hours.

The Serial 1 BASH/MTN is priced at $3999 (£3200).

The first bike in Serial 1's Select Series was the MOSH/TRIBUTE that it launched last year, which is already sold out.
