RUBY Pro
CTM
Trail
RUBY Pro is an alloy electric trail mountain bike (2024), by CTM, from the Ruby lineup. This bike is aimed at riders who prioritize comfort and confidence on longer off-road rides, leaning toward a comfort-leaning position, while being well suited to natural trails and mixed off-road terrain. Standout strengths from the metrics include 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, relative to category specialists, the trade-off is a firmer ride feel than comfort-first options and battery range that is better for shorter daily use than long all-day outings.
