    Front break doesn't work at all

    not very good experiment, not any adjustable feature for different height and age only the saddle is adjustable, overall it doesn't match the high price


    Guardian Bikes

    Hi Reza, Thank you for the feedback! As far as adjustability goes, we opted to use a threadless headset on our Original model as it's a more rigid and durable than a threaded headset. Since the headset is threadless, the handlebars cannot be raised on our Original models. That said, however, we do sell high rise handlebars that you can easily install on the bike. You can find those under "Spare Parts" under "Accessories" on our website. Hope this helps! Let us know if anything else comes up. Thanks, Kaitlin @ Guardian Bikes

    durability of the bikes

    I bought two bikes (20in) - both big and small frames 3 weeks ago. My boys are very active and have fallen off their bikes several times already - it seems that the pedals and other parts of the bikes are not very durable and already have large dents/scrapes that are not appropriate for the time we have had the bikes (and for the price we paid for them!). The pedals seem to be shaved off (the plastic is cheap?). I wonder how long they will last.

    Hi Brianna, We would definitely love to learn more here and get your kiddo back on the road. Can you send us an email or give us a call? We are here to help! Best, Sam @ Guardian Bikes

    Training Wheels Compatible

    We recommend using the balance bike method when teaching your child to ride a bike, but understand all children learn differently.

    Compatible training wheels can be purchased here for our 14", 16", and 20" Bikes.
