Bike trailer for kids. WEERIDE CO-PILOT The Co-Pilot is a safe and wonderful way to introduce your growing child to the exhilarating experience of bicycles, while still keeping them under your control. It is ideal for parents who like to take their child on longer rides than the child’s legs can manage or for parents whose child hasn’t mastered riding just yet. The child can help pedal along or just coast and enjoy the scenery. The Co-Pilot is sturdily constructed – just like a regular 20” bicycle. It includes regular handlebars, seat, pedals, and chain guard.. It attaches easily and quickly to almost any bicycle with a seat post, and folds up for storage when not in use. It even comes with a safety flag to alert motorists. But the most important part of the Co-Pilot is the pivot, and we have the best —the Sync Link Pivot . Our patented pivot ensures a safe & smooth ride for your child. Recommended for ages 4 to 9 yrs.( up to 35kg. )
