kids’ choice

The‎ thick‎ shock-absorbing‎ front‎ fork‎ really‎ impressed‎ me.‎ My‎ child‎ can‎ ride‎ over‎ uneven‎ paths‎ without‎ discomfort.‎ The‎ adjustable‎ seat‎ is‎ a‎ big‎ plus‎ too‎ —‎ it‎ grows‎ with‎ the‎ kid.‎ Overall,‎ it’s‎ a‎ very‎ stable‎ and‎ smooth‎ ride.

Attractive design

This‎ bike‎ looks‎ awesome!‎ The‎ color‎ and‎ design‎ immediately‎ caught‎ my‎ kid’s‎ attention.‎ It‎ stands‎ out‎ at‎ the‎ park‎ and‎ gets‎ compliments‎ all‎ the‎ time.‎ The‎ bell‎ and‎ reflectors‎ add‎ charm‎ and‎ safety.‎ Kids‎ love‎ riding‎ it‎ everywhere.

good bike !

We‎ love‎ the‎ bike's‎ features‎ —‎ from‎ the‎ 21-speed‎ gear‎ system‎ to‎ the‎ adjustable‎ seat.‎ However,‎ it‎ took‎ us‎ a‎ bit‎ longer‎ than‎ expected‎ to‎ put‎ it‎ together.‎ Once‎ assembled,‎ though,‎ it‎ performed‎ wonderfully.

good bike !

This‎ bike‎ handles‎ really‎ well‎ and‎ feels‎ safe‎ and‎ secure,‎ even‎ on‎ rougher‎ paths.‎ My‎ daughter‎ enjoys‎ riding‎ it‎ a‎ lot.‎ The‎ only‎ thing‎ we‎ noticed‎ is‎ that‎ the‎ seat‎ is‎ a‎ little‎ firm‎ for‎ longer‎ rides.‎ A‎ padded‎ seat‎ cover‎ fixed‎ it‎ easily.
