On Nox MTB E-Volution 2.0 e-bikes with a removable 4.6 kg (10,1 pounds) mid-motor drive module from Fazua Evation, you can drive without an electric amplifier, without worrying that a large, heavy motor or battery weights the rider. Sleeve covers down tube without the e-drive.
The German company Nox Cycles began its activities with MTB back in 2004, and a decade later transitioning to e-MTB. Since then, they have used several different electric drives in their bikes, and their new “Take 2 E-Ride 1 bicycle” kit uses an Evation drive from another German company Fazua. The package connects the urban-suburban and mountain bike with one universal electric drive, which can be switched between them. Riders can move to work from Monday to Friday, and on weekends – go to the forests and mountains.
The difference to a typical bicycle electric drive is in the mid-motor drive, which is present on Nox E-Volution 2.0 models. The main idea is the latter is interchangeable between an electric MTB and the e-city bike, since another Fazua company – unlike most e-bikes – has assembled most of the hardware elements into a single universal electric drive system can be easily attached to the bottom of the bike. Fazua’s Evation packs the hardware into a removable all-in-one drive module that snaps into the underside of the bike’s down tube. A 252Wh battery, 250W engine and electronics are installed in a smooth cylinder.
