    Great bicycle

    I am very pleased with the bike purchase and design. My son will try it out only on Christmas. The only disappointment I had is the it had some scratches as you can see in the picture. It is not big, but per the price paid for this bicycle I was expecting have none.

    2 20 inch large bikes

    Overall very positive experience. Assembled the bikes last night. Assembly was very easy. First use was today. One bike was flawless, the other had an issue with chain coming off in shifts to first. Adjusted the “L” screw and I think things are now ok.

    Good design

    It’s a good bike design. I saw the same exact bike by Cannondale, with the only difference being the Guardian has 1 brake lever instead of the traditional 2, and the Cannondale has the quick disconnect for the wheels. The Guardian is priced cheaper, so I’m happy to have purchased this one. The only possible negative I’ve noticed is the chain doesn’t slide back into the selected gear easily when downshifting, but otherwise it’s a great bike and my 6 year old girl loves it.

    Amazing bike

    My son LOVES his bike - it took less than a minute (no joke) for him to master and be a 2-wheeled rider!! When the bike came (it was an early birthday present), there was no seat included, and no protective wrapping/packaging on the bike - I was told the seat would come the next day but we waited 2 days. Not a huge deal, just a little bit of a letdown for my son, who was so excited to ride his new present! WE LOVE the bike though, and will definitely use Guardian for new bikes as he grows.....like so many other reviewers said, I also cannot get my son to come inside. He wants to ride All. The. Time. which is fine by mom! :) Thank you, Guardian Bikes!

    Can't Rate it Perfect but

    Really it was 4.5 stars, because the bike came without the seat. Customer Service was spot on, very easily accessible to handle the problem and answer questions, and the bike is great quality/easy to assemble. My son loves it.
