    I was hopeful

    I was really hopeful with all the reviews of success but that was not the case. She tried it the first day it arrived and hasn't been on it since. She reaches for the smaller, lighter balance bike instead. This is just a guess, she is so hard to read, and she doesn't give me much information to work with, but she seems uncomfortable with the handlebar placement. Can they raised to allow her to be sitting more upright rather than hunched? Her physical therapist isn't sure she can do it without training wheels but she really wants to try. Who knows she may come back to it in a while maybe she wasn't ready.

    disappointed

    The bike is beautiful but too big for our granddaughter to do the balance method as recommended as her feet do not touch the ground even though we measured and were assured it would work if we took off the tail light to get the seat lower. So training will be harder as its hard to balance on tip toes and to walk the bike easily.

    The front brake was completely off and I had to fix that as the string was loose and off when I received it.

    Guardian 20 Inch Large Bike

    Two stars off because the pedals are not long enough, 7 year old's feet slipped off several times while riding, almost crashed. I have to replace the pedals. The pedals that shipped with the bike are 3x3 inch, but the pedals on the 20" Galaxy Nugget (Bikesdirect.com) that I also bought are 4x3 inch, and no feet are slipping off these. Buy the Nugget (out of stock now) and save $100 and also the cost of replacing the pedals. The Guardian bike is otherwise excellent. The kids (ages 7 and 7) love it although one finds shifting on the Nugget is a bit easier. The bike arrived in 3 days and was easy to assemble. Only tool I needed was a box cutter. Shifting is correctly adjusted at the factory, brakes also. Seat adjusts easily. Wheels are true. 15 minutes to assemble and ready to ride. I would buy again if they upgrade the pedals, otherwise will recommend Galaxy Nugget, which is also less expensive.

    Good Bikes, Bad Customer Service

    The bikes are really nice, however, my experience with customer support was surprisingly bad. I ordered two bikes, one arrived on time and the other arrived over a week later pretty beat up. The box was damaged, half-opened, and scrapes on the bike as well. I reached out immediately to let them know, and they answered the phone with “hey.” No, “how can I help you?”, or “you’ve reached guardian bikes”, very much lacking in professionalism. The woman I spoke with asked me to send pictures through a text, and then never got back to me with any updates. Honestly, to pay this much for a kids bike… I expect a little more professionalism than this!
