Ever heard of NOX? No? We’re not surprised! First of all, you won’t find these bikes in any conventional shops, as they’re sold directly on the internet. Secondly, this online seller didn’t even offer E-Mountainbikes until now. Is the Berlin-based company doing it right with the NOX Bike EDT 5.1 Hybrid?

The first impression of the EDT 5.1 is that it looks a lot like its bigger brother, the EDT 6.7. This is no surprise, as the two frames share many parts. The aluminium frame accommodates an integrated Brose motor, which can be powered by either a 580 Wh or 770 Wh integrated battery. In this case motor integration is intended to be beneficial to functionality rather than aesthetics. The travel on the EDT 5.1’s shock can be adjusted between 130 and 150 mm via two different pivot points, as can the fork on its own online configurator. NOX opted for a set of classic 27.5″ wheels with grippy MAXXIS HighRoller II- and DHR II tires.

“Descents are the true strength of the NOX; here the bike makes a great impression with superb handling qualities and riding stability.”

The sitting position on the EDT 5.1 is slightly stretched and for those spending many hours on steep climbs, we recommend moving the saddle forward. The slack seat-angle of 73° will make people with longer legs feel like they’re sitting far back, over the rear wheel. The integrated Brose-motor operates quietly and we really like the natural power transfer. While the power delivery is always sufficient, sprinting isn’t that great. Descents are the true strength of the NOX; here the bike makes a great impression with superb handling qualities and riding stability. The thin tires can’t match the level of comfort offered by the much wider Plus-version and a combination of a slack head-angle and a long reach require a more proactive riding style in order to keep the front wheel glued to the ground. This can quickly become an issue for less experienced riders. The suspension system works smoothly and underlines the powerful image of the bike.

Cool Down
The MAGURA MT5 brakes with a 200 mm rotor are powerful performers. An ideal option for an E-Mountainbike.
The thin MAXXIS-tires are an advantage for agile and fast handling, but can’t really match the grip, traction and comfort of chubbier 27.5+ rubber. We recommend rims with at least 30 mm internal width and 2.5″ tires.
When choosing how to integrate the Brose motor, NOX decides to go the traditional way and renounce a motor-cover or frame integration. Functionally it’s spot on, aesthetically not so great.

NOX Bike EDT 5.1 Hybrid


The NOX Bike EDT 5.1 Hybrid is a solid E-Mountainbike for those in search of an agile and aggressive bike. It’s fast and nimble but still very forgiving. Exactly as its bigger brother, the EDT 5.1 requires a proactive riding style to really excel on the trail. The lack of a set of plus tires makes it one of the less comfortable options.


– Agile handling
– Really good suspension
– Natural ride-feeling
– Long range


– Seat is positioned too far back
– Requires an active riding-styleil
– Thin rims and tires offer low levels of comfort
