Delivery, QC, and Support issues

Package arrived damaged, but contents seemed ok. Training wheels were missing from delivery, it doesn't look like they would be contained in the same box, but the delivery confirmations claim both were in the delivery. Bike also came with scratches that are inconsistent with the damage to the box (damage to box was over rear wheel and scratches are over front,) and obviously occurred before or as the bike was packaged. I attempted to call the support number twice, and both times I was disconnected a few minutes into my wait on hold without any comment or notice. I recognize the box damage is the logistics company - and for the benefit of the doubt, maybe the training wheels were removed ort fell out as a result, but the scratches getting through QC and the hang ups on the phone are issues owned by Guardian.

Hi Matthew, Thank you so much for the detailed feedback. We are so sorry for the experience! This is certaintly not what we aim for our customers. I took a look into everything-- you were able to speak with my teammate Sam who was able to send a replacement bike, some extra accessories, and of course, the training wheels. :) We hope your little one loves their new bike! Best, Kaitlin @ Guardian

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.


Guardian Bikes

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
