Nature BIKES
Range DUSK
Season 2021

Having the latest quieter, lighter Shimano EP8 motor in our benchmark-resetting Stealth Alloy Evo frame with optional battery extender, means the 2021 Dusk R throws some serious shade on the competition, 24/7!

The famous Mondraker Forward Geometry handling was refined at the extreme edge of DH racing so it’s perfect for taming the extra speed and load of powered riding. We’ve optimised our Zero Suspension system to match and teamed our super accurate, integrated battery frame with Fox’s legendary 36 Float Evol fork for a package that delivers total control. Because you’ll want to ride this awesome package so much we’ve also added the option of more than 50% additional range with our booster battery. Add 203mm discs, an OnOff Pija dropper and Maxxis Rekon tires for a splendid blend.
