Recommended Rider Height:

122-147cm

Colour - Silver

Top Tube Length - 16.9

An 18 inch bike suits a rider of about 122 to 147cm, usually 7 to 11 years old, on an 18 to 18.5 inch top tube. It is the last step before a full size 20 inch.

Rider height	Wheel size	Top tube
60 to 91cm	12"	12 to 12.5"
81 to 106cm	14"	14 to 14.5"
96 to 122cm	16"	16 to 16.5"
122 to 147cm	18"	18 to 18.5"
147 to 157cm	20"	19.75 to 20.25"
157 to 168cm	20"	20 to 20.5"
168 to 175cm	20"	20.25 to 20.75"
175 to 183cm	20"	20.5 to 21"
183 to 190cm and up	20"	20.75 to 21.5"
160cm and up	22"	21 to 22.25"
160cm and up	24"	21.75 to 22"
160cm and up	26"	22 to 23"

Sizes overlap on purpose, so personal preference comes into it. If your rider is near 147cm and still growing, look at a 20 inch instead: it is the size they will keep riding.

How to measure

Stand your rider against a wall in the shoes they ride in, heels flat, and mark the top of their head. Measure from the floor to the mark.

Between an 18 and a 20? Take the 20. It is the size they will keep riding, and an 18 gets outgrown quickly.
They should be able to stand over the top tube with both feet flat on the ground.

Not sure? Send us their height and we will tell you what we would put them on.
