  • Stylish bike any girl would love
Color: Black Size: 20"
Easy to put together. I did it all by myself rather quickly. All parts were in packaging. Everything was packaged very well also. The bike itself is a Good quality bike and is very stable. Looks really good. My daughter is in love with it. We upgraded to a bigger bike from the one she had before. This one will last her a couple years now. It looks exactly as pictured colors and all. The only thing I did not add on the bike was the wraparound cushion part for the bar in the middle. My daughter did not like that part. She thought it made the bike quick tacky. But other than that great boy came next day in time for Christmas. I was very pleased! ... show more

  • Sturdy, Comfortable, and Perfect for Young Riders
Color: Pink Size: 20"
he Dynacraft Magna Sapphire Bike is an amazing choice for my child! The sturdy steel frame provides excellent durability, and I love how it can withstand rough rides and outdoor adventures. The front and rear hand brakes are responsive and give my child full control while riding, ensuring safety and confidence as they learn to ride. The adjustable seat is a fantastic feature, as it grows with my child, offering a comfortable riding experience. The bike is the perfect size for kids aged 6-10, and the kickstand makes it easy to park and store when not in use. The colorful design adds to the fun, and my child loves how cool and stylish it looks. This bike has been a great investment for getting my child outdoors and encouraging active play. It’s perfect for neighborhood rides, parks, and adventures! This product offers great value for money, excellent functionality, and is easy to use. If you're looking for a reliable, fun, and safe bike for a young rider, I highly recommend the Dynacraft Magna Sapphire Bike! Highly recommend! ... show more

  • This is a great product for its price.
Color: Pink Size: 20"
Assembling it was easy. It had clear instructions. I did have to pump up the tires which wasn't a big deal just be prepared if you don't already own a pump. I bought this as a Christmas gift so the price atleast at the time was one of the cheapest I'm not sure if it is now. The only thing I would have liked it if it had clearer size comparison so I would know if it would fit my niece needs. It was a little small but she was still able to ride. She said that it's comfortable ride. ... show more

  • Missing parts
I believe this bike is missing a part because the seat is loose. I will call the manufacturer or send it to a bike shop to see if they can fix the problem.

  • Ignore the Negative Reviews
Color: Pink Size: 20"
We almost didn't purchase this bike because of so many negative reviews. In the end we opted to give it a try as it was a replacement gift for a neighbor. My husband is a bike junky from mountain biking, down hilling. BMX and being a guru with brands. He has expressed the necessity to write a Five star review. He said it was easy to put together, tires fit into forks easily, colors are perfect for a girl, simple design with a kick stand and no hand brakes to tackle up. Give it a try. She loved it. ... show more

  • Impressive
Color: Pink Size: 20"
This bike is way better than the picture shown! It looks great and comes half assembled in the box. My daughter loves the color scheme and it looks like it is compatible with upgrades, such as a crank and a faster sprocket πŸ˜‰. I'd highly recommend this product and the price is a great value
