Just getting into BMX racing and looking for your kid's first race bike and not too sure about specifications and geometry? No need to stress because French brand Inspyre knows plenty about how to put together a race bike that will stand up to the type of riding that you are no doubt going to dish out as you learn the art of BMX racing.

Not only is the 2026 Inspyre Micro 18 a great looking race rig, especially in this blue polish, the frame is full aluminium and forks 100% chromoly fork. In fact this spec of frame and forks represents the best value that we offer at the entry level of race bikes.

The Vee Speedster tyres will see your littlest carving through the turns with plenty of speed and the double walled aluminium rims will take the cases that no doubt you will be dishing up as you get some sweet air. This bike will take a beating out on the track and ask for more as you get faster and faster.

Not only are these micro Inspyres spec's out to win, they are available in two contrasting colours that should appeal to every sprocket/potential Olympian out there.

Race frames are sized by class, and the class you ride is set by rider height rather than age.

Size	Rider height	Top tube
Micro (18" wheels)	Under 120cm	16.25"
Mini (20" wheels)	110 to 140cm	17 to 18"
Junior	120 to 150cm	18.25 to 18.75"
Expert	130 to 170cm	19.5 to 19.75"
Expert XL	145 to 170cm	20 to 20.75"

Pro XXXXL	180cm and up	22.5"
Cruiser (24" wheels)	175cm and up	21.5" and up

Heights overlap between classes on purpose. Where you land in two, a growing rider is usually better on the larger, and a rider who wants the bike to turn faster on the smaller. Some brands label the Pro size Pro L, with the same fit.

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 two sizes and still growing? Take the larger size.
Racing gates and wanting the bike to turn faster? Take the smaller size.
Top tube is the number that actually changes the fit, so compare it against the bike they ride now.

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