Solitary rate. 20" wheels. Uncertain how you determine bike structures ... exactly what I can tell you is that the structure crossbar is 17.5" off of the ground at it's cheapest factor and the handlebar grips have to do with 30.5" off of the ground. It was sized terrific for our 6 to 8 year olds.
Health condition excels ... paint is in decent shape, some chips but nothing even more compared to you 'd expect for an utilized bike, All running gear (brakes, chain, wheels, tires etc) are great. Necessities nothing. There is surface area rust on the chromed components such as tire hubs.
