What size bike?

My son wants a new bike for his birthday and he does need a new one because he grows like a weed. What size would you recommend for a 7 year old. He's 50 inches tall and 55 pounds.

Thanks.

  • Your best bet would be to go to a specialty bike store and have them size him. Even if you don't buy it there, you will know what measurement to look for when you go shopping for real.

  • i think you're suppose to measure the inside of his leg and get a bike that matches with that. my (almost) 7 year old has an 18 inch bike but she's very tall for her age.

  • He should be able to sit on the seat and have his feet touch/nearly touch the ground.

  • My son is 45" tall at 5 years old and fits perfectly on his "16 bike. So for your 7 year old I'd probably suggest a "20. But I agree with others, the store would know best. Don't wanna buy the wrong size!

  • 20" bike. But all depends on the build of the bike. He will need to go in and sit on them and grab the handles to make sure it fits him right. Some bikes have the handles closer to the seat than others and you don't wanting him stretching so much to hold on that he has a hard time balancing it. Seats are adjustable, but again, depending on what kind of bike the frame may naturally have the seat lower than others.

  • The inseam is the length of the leg, measured on the inside from crotch to ankle. In general, children ages 2 to 4 with 14- to 17-inch inseams need 12-inch wheels, ages 4 to 6 with 16- to 20-inch inseams need 14-inch wheels, ages 5 to 8 with 18- to 22-inch inseams need 16-inch wheels, ages 6 to 9 with 20- to 24-inch inseams need 18-inch wheels, ages 7 to 10 with 22- to 25-inch inseams need 20-inch wheels, and kids 9 years and older with 24- to 28-inch inseams need 24-inch wheels. The ages and inseam measurements overlap to allow for individual height differences.
