Unno Boös slides 750Wh battery into Bosch-driven VPP linkage eMTB

Spanish carbon mountain bike producer, Unno, has launched its first eMTB; the Boös. Sporting 160mm of rear wheel journey delivered by its digital pivot level suspension platform, the Boös rocks a Bosch CX Gen 4 motor with a 750Wh battery housed contained in the downtube. The whole eBike will set you again €9,995; it should finally be accessible in three sizes, however solely a type of is on the market at launch.

The Unno Boös is greater than a little bit intriguing. The truth that it’s an Unno is sufficient to make us look twice; this eMTB follows within the footsteps of a few of the extra attention-grabbing bikes we’ve coated on Bikerumor, together with the Unno Sprint 130mm journey 29er, the sub 800g Unno Aora hardtail, and the Unno Ever DH Bike, all of which have been dreamed up and realized by former World Cup DH racer, Cesar Rojo.

This eMTB runs a VPP linkage design, new to Unno who’ve beforehand made use of dual-link suspension platforms throughout their vary of shorter journey mountain bikes. Like we see on the Ever DH Bike, nevertheless, its Fox X2 shock sits inside a tunnel created by the seat tube, simply above the Bosch motor. That works to maintain weight distributed close to the underside bracket, making for a motorbike with a low heart of gravity. Unno advocate riders run something between 30% and 40% sag, on both an air or coil shock.

The Unno Boös geometry is attention-grabbing in that it’s pretty progressive in some methods, however a little bit conservative in others. Throughout the S1-S3 body sizes, the chainstay size is constant at 450mm, whereas attain measurements are quoted as 435mm, 470mm and 510mm. The pinnacle tube angle sits at 64°, pretty customary for a motorbike with these journey numbers, whereas the seat tube stands to consideration at 77°.

The Unno web site says, “There’s a fistful of room between you and the bars, so aggressive driving is welcome!”. Whereas the attain figures are beneficiant, and the longish rear-center size will certainly encourage energetic weighting of the entrance wheel, I worry the seat tube size will probably be a limiting consider simply how aggressively this bike may be ridden. Take the S1, for instance: Unno say it’s suited to riders shorter than 175cm. Whereas riders who’re very near that peak might haven’t any problem in any respect, riders shorter than that who would usually be fairly comfortable on a motorbike with a 435mm attain, might battle with clearance above the saddle.

Unno bikes stand out for a variety of good causes, considered one of which is their tremendous light-weight made-in-Spain carbon frames. The Unno Boös isn’t any totally different, weighing a claimed 22.6 kg in S2 with the identical spec seen all through this text.
