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. \u003c\/p\u003e\n\u003cp\u003eHead 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.\u003c\/p\u003e\n\u003cdiv style=\"text-align: left;\"\u003e\u003cimg alt=\"\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0281\/2769\/0849\/files\/IbisCycles-Oso-S-GeometryChart-2026-TweedValleyBikes.jpg?v=1776671423\"\u003e\u003c\/div\u003e\n\u003cp\u003eModular 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. \u003c\/p\u003e\n\u003cp\u003eThis 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. \u003c\/p\u003e\n\u003cp\u003eDefault wheel size varies by frame size: Small to XM bikes come set up with MX wheels and L-XL are full 29'.\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"text-decoration: underline;\"\u003e\u003cstrong\u003eSpecification\u003c\/strong\u003e\u003c\/span\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cspan\u003e\u003cstrong\u003eFrame:\u003c\/strong\u003e Full Carbon, DW 4 Suspension, 150mm travel\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003e\u003cstrong\u003eFork:\u003c\/strong\u003e \u003cmeta charset=\"UTF-8\"\u003eRockShox Pike, Base, 140mm, 29”\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003e\u003cstrong\u003eShock:\u003c\/strong\u003e RockShox Deluxe Select+, 210x52.5mm\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003e\u003cstrong\u003eWheelset:\u003c\/strong\u003e Ibis Blackbird Send Alloy 32 hole, MX\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003e\u003cstrong\u003eTyres:\u003c\/strong\u003e Front: Maxxis Assegai 29\"x2.5\", Exo MaxxGrip  Rear: Maxxis Minion DHRII 2.5, Exo+, MaxTerra\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003e\u003cstrong\u003eBrakes:\u003c\/strong\u003e SRAM Maven Base\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\n\u003cspan\u003e\u003cstrong\u003eRotors:\u003c\/strong\u003e SRAM Centerline 220mm, 6-Bolt\u003c\/span\u003e\u003cspan\u003e\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003e\u003cstrong\u003eCranks:\u003c\/strong\u003e SRAM EX1, 160mm, 34T Steel Ring\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003e\u003cstrong\u003eChain:\u003c\/strong\u003e SRAM Eagle 90 Transmission\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003e\u003cstrong\u003eCassette:\u003c\/strong\u003e SRAM XS 1275 Eagle T-Type, 10-52t\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003e\u003cstrong\u003eRear mech:\u003c\/strong\u003e SRAM Eagle 90 Transmission\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003e\u003cstrong\u003eShifter:\u003c\/strong\u003e SRAM Eagle 90 Transmission\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeatpost:\u003c\/strong\u003e \u003cmeta charset=\"UTF-8\"\u003e KS Vantage Dropper, 34.9mm S\/M 170mm XM\/XL 210mm\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003e\u003cstrong\u003eSaddle:\u003c\/strong\u003e WTB Silverado Fusion CrMo 142\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003e\u003cstrong\u003eHandlebar:\u003c\/strong\u003e Blackbird 35 Aluminum Riser Bar 800mm\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003e\u003cstrong\u003eStem:\u003c\/strong\u003e Blackbird 35 Stem\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eGrips:\u003c\/strong\u003e Lizard Skins Strata Single Clamp\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eDrive Unit: \u003c\/strong\u003eBosch Performance CX Gen 5\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBattery:\u003c\/strong\u003e Bosch 600Wh\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Ibis Cycles","offers":[{"title":"Silver Surfer \/ Small (pre-order)","offer_id":57024404980087,"sku":null,"price":7399.0,"currency_code":"GBP","in_stock":true},{"title":"Silver Surfer \/ Medium (pre-order)","offer_id":57024461767031,"sku":null,"price":7399.0,"currency_code":"GBP","in_stock":true},{"title":"Silver Surfer \/ Extra-Medium (pre-order)","offer_id":57024461799799,"sku":null,"price":7399.0,"currency_code":"GBP","in_stock":true},{"title":"Silver Surfer \/ Large (pre-order)","offer_id":57024461832567,"sku":null,"price":7399.0,"currency_code":"GBP","in_stock":true},{"title":"Silver Surfer \/ Extra Large (pre-order)","offer_id":57024461865335,"sku":null,"price":7399.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0281\/2769\/0849\/files\/IbisCycles-Oso-S-SilverSurfer-90-2026-TweedValleyBikes.jpg?v=1776773635","url":"https:\/\/tweedvalleybikes.mom\/products\/ibis-cycles-oso-s-90-mx-29-2026","provider":"Tweed Valley Bikes","version":"1.0","type":"link"}
