The Nox Helium Enduro and All-Mountain 2022 electric mountain bikes receive the Fazua Ride 50 Trail motor


Nox Cycles has added a new range of Helium Enduro and All-Mountain e-MTBs featuring the Fazua Ride 50 Trail motor, lighter and more versatile versions of the more performance-oriented Brose motor-equipped bikes. In addition to new geometry and frame designs for 2022, the new bikes benefit from the modular design of the Fazua drive unit which allows for easy removal, meaning these eMTBs can be switched to a version acoustics on their own, then again as you see good.

First introduced in 2019, Nox Cycles’ line of Enduro and All-Mountain electric mountain bikes are getting a major overhaul for this model year. The Helium 2022 eMTBs (and the All-Mtn) use the same linkage design as their Brose motor-equipped hybrid eMTBs; which provides a whopping 180mm of rear wheel travel on the Helium Enduro 7.1 and 160mm of rear wheel travel on the Helium All-Mtn 5.9.

The original Helium Enduro used a 29er wheelset, while the new bike is a mixed-wheel rig with a 29er wheel up front and a 27.5er wheel in the rear. The Helium All-Mtn retains its 29″ wheelset for 2022. Nox Cycles offers three models of each; Pro, Expert and Comp, all featuring a carbon front triangle and aluminum swingarm.

The 180mm-travel Enduro 7.1 eMTB gets a head tube angle of 64.1° paired with a fairly slack (in modern terms) seat tube angle of 73.6°.

Both frame size options offer reach measurements of 437mm and 466mm, respectively. The length of the base is adjustable thanks to a flip-chip, going from 450 mm in the short position to 465 mm in the long position.

The Helium All-Mtn geometry is almost identical to that of the Enduro platform despite its 29″ wheelset and 160mm of rear wheel travel. A head angle of 64.2° is paired with a seat tube angle of 73.7°, with reach measurements of 438mm and 467mm on the medium and large frames, respectively. The length of the base is also adjustable between 450 mm and 465 mm.

Nox Cycles tells us that the new e-bikes are designed to ride very naturally, more like a regular mountain bike than an eMTB. This is consistent with the fact that the Fazua RIDE 50 Trail motor is by no means the most powerful on the market, producing a peak torque value of 58Nm, compared to the 85Nm you’ll get from a Shimano EP8.

The modular design of the Fazua drive unit allows the rider to remove the battery and motor unit from the bike, converting Nox Helium eMTBs into acoustic versions of themselves. The conversion significantly reduces the weight of the bike, although the 1.2kg bottom bracket part of the Fazua drive unit (the gearbox) remains in place – this is where the torque sensors are located and double-sided rate.

In the Fazua Motor line, the RIDE 50 Trail motor sits above their Evation motor, and is said to be 10% more powerful with increased motor efficiency, and it is 6% lighter. On Nox Helium bikes, the motor is paired with a 252Wh battery on their “Short Track” models and two 252Wh batteries on the “Long Track” models.
