About the Oso S Model
Now completely re-designed, the brand new Ibis Oso overhauls everything from the suspension design to geometry and motor system. As with the their recent and well regarded mountain bikes, the new Oso runs on the excellent DW4 linkage which produces a great balance of plushness, support and bottom out resistance. A 600W internal battery keeps weight low and central in the frame for intuitive handling while compatibility with the Bosch Powermore extender allows a 250W booster to be added for the biggest days out. Drive comes from the Bosch Gen 5 CX motor, which has become one of our absolute favourites on the market; its reliability is unmatched and at a current max output of 100Nm torque and 750 watts it is powerful enough for almost everyone.
Head angles sit at a sporty 64.4' on the trail focused S model, while almost every other number including BB height is tuned by size across the 5 sizes on offer.
Modular dropouts allow you to run either a 27.5 or 29' rear wheel as well as switching between longer or shorter chain stays so no matter what you prefer, the Oso can be adapted to suit. That's already a lot of adjustment but there is even more available; by swapping clevis, shock and fork the bike can be adapted into either TR 160mm /1 50mm or HD 180mm / 165mm configurations making it incredibly future proof.
This version, the S, turns the Oso into a sharp handling, short travel trail bike. With just 130mm of rear suspension it pumps, jumps and responds exceptionally well to rider input while still having enough capability to take on the odd rougher section. For faster and smoother trail networks it's the perfect full power E-Bike, bringing the trail to life in a way the longer travel bikes just can't compete with. A simple, but quality build kit using RockShox suspension, Maven brakes and a SRAM Eagle 90 drivetrain delivers solid functionality while keeping costs down.
Default wheel size varies by frame size: Small to XM bikes come set up with MX wheels and L-XL are full 29'.
