Used but in basically new condition. This is the versatile Encore X double-seat bike trailer/stroller from Burley, retailing new for $699.95.

Features include a full suspension system for a smooth ride, 5-point harness with padded bench seat, all-weather weather-resistant cover, UPF 50+ tinted windows, roll cage for protection, and a spacious cargo area.

Converts easily between biking and strolling modes. This listing also includes the jogger wheel/kit (not shown in photos) — a $149.99 value on its own — so you're ready to run, not just stroll or ride.
