Complete Child Bike Seat Our kit includes a cushioned seat, a pair of foot pedals, handlebars, and all necessary installation hardware. This not only provides a comfortable seat for your children but also addresses the issue of dangling legs and the lack of safety handles, allowing your kids to have an enjoyable ride with you! Durable Structure & Secure Installation The support clamp of our child bike seat is constructed of heavy-duty metal, strong enough to withstand loads up to 48 lbs. Plus, its inner sides are covered with rubber to maximize slip resistance for enhanced safety while preventing scratches on your bike frame. This kid bike seat is suitable for 2~5-yeard-olds. Adjustable Seat Angle Simply loosen the silver nuts under the cushion, then you can rotate the seat up and down to the desired angle, ensuring you get the most comfortable position for your kids. Please note: remember to tighten the nuts and all the fixing accessories before a ride. Universal Fit The supports clamping size is adjustable to fit on all MTBs while the handlebars fixing holes range from 0.59-1.57(15-40mm), suitable for all bike handlebar frames. The support clamp comes with a quick-release handle, and a simple lift makes a quick remove if you want! Easy to Install The assembly is simple by bolt & nut connection. We include an all-in-one wrench for you to tighten all the nuts and a small wrench for you to install the handlebars.
