A 20 inch bike is generally the best fit to buy for 6 and 7-year-olds. If your child is already 8 or is a very tall 7-year-old, also consider 24-inch bikes as they would offer more room for growth. If your child is a confident rider, it's best to set the bike's seat about 2 – 3″ above the child's inseam.

The most popular bike sizes for young kids are 16- 20- and 24-inch, and there's overlap in ideal rider height between each of them. (Additionally, 14-, 18-inch and 22-inch options exist, but they are much less common.)
In the world of bicycles, there is nothing quite like a 20 inch bike. Smaller bikes fit neatly into the category of children's cycles, while larger two-wheelers are designed for older children, teenagers, and adults. This strange size category includes bicycles for riders of virtually every size and persuasion.

Look for listed stand-over heights for specific bikes and compare that number to the child's inseam. The inseam should be higher than the stand-over height so the child isn't resting on the top tube. (For example, if the child's inseam is 18,†they'll want a bike no bigger than a 17†stand-over height.)

They can ride the bike easily if it is designed according to their requirements. In most cases, tiny women will find this bike size suitable for cycling. But if 24-inch wheels are for kids then they will get fatigued or uncomfortable while riding. Because the bike is constructed based on the kid's body structure.
These kids training wheels are easy to install and use. Compatible with most 12" - 20" bikes. Designed for young riders these training wheels provide safety during wobbly rides thanks to the all steel construction.
Women whose heights are 5.4†and below can ride a 24-inch bike. This is because the frame is the right height to accommodate the length of their legs and will ensure they find it easy to peddle. It also means that you need to get a smaller bike with a sizeable frame.

The women that are 5 feet, 5'1" range, it's a personal preference between a 24" or a 26". And then also, if you have shorter arms or shorter legs, that's gonna depend, too. Shorter arms or shorter legs, if you're 5 foot or 5'1", I'd recommend a 24". If you believe your legs are average length, 26" is a great bike.
