Spanish carbon mountain bike manufacturer, Unno, has released its first eMTB; the Boös. Sporting 160mm of rear wheel travel delivered by its virtual pivot point suspension platform, the Boös rocks a Bosch CX Gen 4 motor with a 750Wh battery housed inside the downtube. The complete eBike will set you back €9,995; it will eventually be available in three sizes, but only one of those is available at launch.
Unno Boös eMTB
The Unno Boös is more than a little intriguing. The fact that it is an Unno is enough to make us look twice; this eMTB follows in the footsteps of some of the more interesting bikes we’ve covered on Bikerumor, including the Unno Dash 130mm travel 29er, the sub 800g Unno Aora hardtail, and the Unno Ever DH Bike, all of which were dreamed up and realized by former World Cup DH racer, Cesar Rojo.
This eMTB runs a VPP linkage design, new to Unno who have previously made use of dual-link suspension platforms across their range of shorter travel mountain bikes. Like we see on the Ever DH Bike, however, its Fox X2 shock sits within a tunnel created by the seat tube, just above the Bosch motor. That works to keep weight distributed near the bottom bracket, making for a bike with a low center of gravity. Unno recommend riders run anything between 30% and 40% sag, on either an air or coil shock.
The Unno Boös geometry is interesting in that it is fairly progressive in some ways, but a little conservative in others. Across the S1-S3 frame sizes, the chainstay length is consistent at 450mm, while reach measurements are quoted as 435mm, 470mm and 510mm. The head tube angle sits at 64°, fairly standard for a bike with these travel numbers, while the seat tube stands to attention at 77°.
