For a weekend we used the HELIUM 7.1 ENDURO PRO PHANTOM, a hybrid bike by NOX.
DISCOVER ALL MODELS ON www.rullo.eu/nox-bici
Immediately I realized that Nox worked to present a light and lively bike, with Fazua and FOX components with 180mm excursion
One of the interesting things about this bike is the very light and minimally invasive Fazua engine, it can be completely removed from the frame and It becomes an organic bike.



Its carbon frame still emphasizes a light and fun bike and is available in two versions: the Expert with Rockshox components (5,999€) and the Pro (7,799€) that we used. Both are 27.5" or 29" and you have the possibility to have the second battery.
Fox 36 Float Factory fork and DHX2 spring shock immediately express his Freeride soul, 2.4 tires and 27.5 wheels make it sparkling, Sram cassette has an excellent pedalability and the Magura MT7 with 200mm front disc and 180mm rear disc guarantee an excellent braking.
The Helium’s heart is the Fazua Evation, compact and lightweight with a 250 W battery of 60 Nm of power and the 250 Wh battery inserted into the oblique tube, 3.3 kg in total.


What changes from a classic e-Bike engine?
What I immediately noticed is how it is free from mechanical influences with On and off mod,I has a natural ride and the feeling in the saddle like an organic bike.
Fazua is separated from the central movement, there is no resistance or drag and you forget to have a help.
On the handlebar there is only one control without display and you can manages three levels of assistance.
Each mode has a different color and you see 10 leds battery level: Green "Breeze" delivers 125 watts, blue "River" delivers 250 watts and purple "Rocket" delivers up to 400 watts.
Holding down the "down" button activates the Walk mode.
The eleventh led indicates with different colors error notifications.


The HELIUM 7.1 ENHURO PRO PHANTOM of Nox getting an a plus: it is a light bike, with a rear very reactive especially in berms, it’s 27.5" wheels make it very handy and fun and Fox suspensions glue it to the ground where it is needed.
Fazua motor guarantees an excellent grip uphill without tearing, the insertion or increase in power of the engine is very fluid and it’s perfect for a rider who already pedals and who does not want to give up muscle.



You want downhill fun in a dimension unknown to e-bikes uphill and an extra portion of power in your legs? A bike that you can retrofit as quick as lightning and that gives you unlimited freedom without a motor for bike park days and shuttle excursions?
If you answer YES to these questions, then our NOX HeLIUM ENDURO 7.1 is the right bike for you. A fitness saver uphill for as many downhill kilometres as possible. An E-MTB for extreme, long tours on single trails and in rough terrain or bike parks - with or without E-Power.
The Fazua evation 1.0 Drive System is used as the motor. With the evation drive, the German motor manufacturer Fazua offers an electric drive system that is primarily aimed at sporty demands and yet still conveys the natural feeling of a non-motorized bicycle. An innovative approach that perfectly matches the vision and passion of NOX: to constantly rethink e-Mountainbikes and take them to a new level.
