Query: Very Sturdy Beginner Bike For 5-7 Year olds

Ordered two of these bikes for my twins. They are very sturdy and well designed. The bike is roughly 50% assembled out of the box and final assembly was a snap in 15 minutes. The only tools required were a few sockets and a wrench to attach the front wheel, training wheels, pedals, hand brake and handle bars. The training wheels work very well. As the bike is only a 16 incher, when the kids do fall off of the bike after removing the training wheels, it's not a long drop. Though well packaged, expect some paint to get scraped off during shipping. As usual with imported bikes, you have a 50/50 chance of getting a leaky tire inner tube, and these were no exception (easily repaired with a patch kit). The bikes DO NOT come with reflectors. Reflectors are an optional item and you'll have to purchase them seperately (less than $5 at any local department store). Overall, they are an excellent value and the kids love the Star Wars graphics.
