Document: i bought this bike for my daugther its 5 years , and she is very happy with the Bike, excelent product and its very resistant bike
We recently purchased this bike for our 5 year old girl and she absolutely loves it. It's sturdy and stylish, with very little assembly required. I recommend this bike to everybody. We received great customer service, All in all, it's money well spent.
We ordered this bike and a smaller model from Dakota Cycle as last minute gifts right before Christmas, and were very happy with the customer service the company (Tobias) provided. He was very friendly and accommodating, and he made sure we received both the bikes and some extra training wheels we needed in just a couple of days and in time for Christmas.The bikes are both very nice looking and seem like great quality, and our daughters love them!
Our 4 year old daughter wanted a lavender bike and this was it. Bike was easy to assemble, feels sturdy. Our daughter is absolutely enjoying this.
My girl loves this bike. It is pretty and can carry all her toys, dolls, etc. And it is a tough bike. We've had it for several months now and it has held up well. I have taken out for a spin a couple of times (much to the amusement of the neighborhood kids). While not quite my size, the bike feels solid and didn't seem to mind my extra weight.We went with this bike because we wanted one that would last for our two girls.
Lovely "big girl" bike- with all of the styling and features of a larger bike... in a 16" size for younger kids. Good quality; well packed and shipped. Very happy with this bike.
I would recommend this bike to anybody. It may not be the best, but it is very well built, quite robust and has a very girly design without being an ugly bubblegum pink. The basket could be just a little bit better, but it's Ok.
I tried just taking off the guard, but my girl would have none of that. This isn't a terrible issue. Installed with the chain guard, the training wheels make the guard rub against the chain a little. Again, this isn't too hard to fix, you just need to play around with it.
Great bike! Very pretty and my daughter loves it. Easy to put together and a great quality bike. My daughter can't wait for the snow to melt do she can ride it.
Bike is perfect size for our 6 year old granddaughter. She loves it. It was fairly easy to assemble and is beautiful.
