The new NYTRO GRINTA is pure freedom. Gravel has wonderfully expanded the possibilities of traveling on roads that were not even contemplated by road cyclists until yesterday. With NYTRO GRINTA you can go even further thanks to the thrust of its Fazua Evation engine able to support you to overcome the obstacles between you and the fun! The Fazua Motor offers three levels of assistance: Breeze: a gentle, constant and 100 watts strong tailwind even at low rider power River: progressive and very sporty mode, for a smooth riding experience. The strength of the support precisely follows your foot and your own power. Give a lot - and get a lot from the motor (max. 210 watts) Rocket: aggressive assistance that helps you to tackle the steepest sections even with moderate driver power (max. 250 watts)
