RUBY PRO
CTM
Trail
RUBY PRO is an alloy electric trail mountain bike (2023), from CTM, part of the Ruby family. Rider-wise, it fits 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 well suited to natural trails and mixed off-road terrain. The main strengths in the metrics are strong value-for-money versus many similar bikes, good fit flexibility for dialing in rider position, and strong speed potential on smoother terrain. At the same time, the trade-off to keep in mind is a firmer ride feel than comfort-first options and battery range that is better for shorter daily use than long all-day outings.
