From Marin: 

Our critically acclaimed and best-selling Fairfax has gone electric. The all-new Fairfax E brings the power to scoot you along with 40Nm of torque from the rear hub, quietly and seamlessly adding a boost to your pedaling. The 340Wh battery is cleanly integrated into the Series 2 aluminum frame's downtube, while a Shimano 8-speed Altus drivetrain provides plenty of gearing range. Finally, hydraulic disc brakes from Tektro allow for controlled and comfortable stopping power in all conditions.
