    • Smooth ride and my kid loves it
Color: Red Style: 14 Inch With Kickstand Pattern Name: Basic Magnesium
I am really impressed with this bike. It was very easy to assemble and the adjustments were simple to make. The frame is lightweight and comfortable for my child to handle. The red color looks great in person and my kid loves everything about it. The hand brakes work smoothly and the little bell is a fun touch that my child keeps using. The ride itself is very smooth and feels well made. Overall, this has been a great purchase. My kid is excited to ride it every day and I have no complaints at all. 5 stars. If you want, I can also polish the title to match this exact tone. ... show more

    • Simply awesome!
This bike is awesome! Super easy directions to follow and assemble. Fits my 5 year old perfectly with room to grow. He hopped on and rode off straight away. Love that the kickstand is near the back tire so it doesn’t get hung up on the pedals.

    • Quality and Safety
Color: Red Style: 14 Inch With Kickstand Pattern Name: Basic Magnesium
This bike is beautiful, the build and paint are high quality and the 14" fits the perfect size gap for our 3 year old. He feels comfortable and we feel he is safe, we love the disk breaks and how responsive they are to his little hands. Great buy.

    • Rides Great! Not Lightweight.
Rides Great! Not Lightweight. The geometry is really nice for a 16" which makes it ride very well, but it's definitely no lighter than most bikes you'd find at Walmart. It may be cast from magnesium, but most of the frame is actually solid, not tubular, so it's much heavier than it looks. All that being said, this is my 4yo son's first pedal bike and he was able to hop on and immediately take off riding! (we started on a 12" strider). He's 43" tall and It's a hair on the big side for him, but it is really stable, has great geometry and really does work very well. Do note that on top of some assembly, the brakes actually needed quite some adjustment out of the box, so much so that they wouldn't have actually stopped the bike when pulled. Adjusting the cable resulted in a much firmer brake feel. Also note that this style of brake doesn't fully lock up, so they're great for learning how to operate lever brakes without being too "tricky". That said, older kids (dad) may not be able to stop easily down large hills. ... show more

Excellent good looking bike with super easy assembly. This is my kid’s second from Royal so I can vouch for durability as well. This model is lightweight as well.
