RoyalBaby Kids' Bikes Editorial Review

The RoyalBaby Kids Bike Cubetube is a great choice for parents looking to buy a bike for their child. The bike comes in various sizes ranging from 12" to 20" and includes training wheels and a kickstand. The recommended tyre pressure for all sizes is 40psi. The handlebar is designed to avoid sharp turns, preventing side falls. The bike can be used on grass without any issues. However, there have been complaints about the quality of the product during delivery. Some customers claimed that the paint had worn off, and the back reflector was missing its bracket to attach it to the bike. There were also issues with the size, with some customers claiming that the bike was too heavy and too tall for their child's height range. Some customers also reported issues with parts of the bike breaking, such as brake parts and the chain.
