Limitation: precise fitment for components should be confirmed before purchase to avoid mismatch in mounting points.
KEYU F7L Enduro Stealth Bomber Frame
Best for riders seeking an extended-seat option with stealth bomber styling and battery bag compatibility. The F7L frame combines endurance with added payload options, making it suitable for longer rides or touring-style builds. Caution: verify battery bag compatibility and accessory mounting space for your exact setup.
Buying Guide
