Orbea
Crosscountry
KERAM 30 20mph 27.5 is an alloy electric cross-country mountain bike (2023), from Orbea, part of the Keram family. It suits riders who prioritize comfort and confidence on longer off-road rides, with a setup that gives you a comfort-leaning position, with a surface profile that is best for smoother trails and efficient rolling. On MatchBikes metrics, it scores well for good fit flexibility for dialing in rider position, balanced, versatile speed for everyday riding, and all-round climbing capability rather than a narrow specialty. Compared with more specialized alternatives, the compromise is a firmer ride feel than comfort-first options and battery range that is better for shorter daily use than long all-day outings. If this looks close to what you want, compare this bike on MatchBikes.com against similar models.
