THEOS R50 P 29″/27.5″ 725Wh
Kellys
Trail
THEOS R50 P 29″/27.5″ 725Wh is an alloy electric trail mountain bike (2024), from Kellys, part of the Theos family. It is a strong match for a wide range of riders thanks to its fit flexibility, with a balanced riding position, while being well suited to natural trails and mixed off-road terrain. Metric-wise, it stands out for a comfort-leaning ride feel over longer rides, good fit flexibility for dialing in rider position, and strong climbing friendliness for sustained uphill riding. The main trade-off is less emphasis on outright speed than speed-focused builds and a value score that depends more on priorities than pure price efficiency.
