ROCKRIDER
Crosscountry
27.5″ Hardtail Electric Mountain Bike E-ST 100 is an alloy electric cross-country mountain bike (2023), by Rockrider, part of the 275 family. It suits a wide range of riders thanks to its fit flexibility, leaning toward a balanced riding position, while being best for smoother trails and efficient rolling. On MatchBikes metrics, it scores well for strong value-for-money versus many similar bikes, good fit flexibility for dialing in rider position, and balanced, versatile speed for everyday riding. At the same time, what it gives up slightly is a firmer ride feel than comfort-first options and battery range that is better for shorter daily use than long all-day outings.
