The Inspyre Neo Micro — 18" wheel configuration, 15.75" top tube. This is the correct starting point for the youngest BMX racers: riders typically aged 3 to 5, transitioning from a balance bike onto a race track. The 18" wheels and Reactiv Geometry are proportioned for this size range, not scaled down from a larger bike. The flip/flop rear hub allows the bike to be run fixed or freewheel as skills develop.

Frequently Asked Questions
Is the Neo a good first race bike?
Yes — it's purpose-built for new competitors and riders taking their first steps into structured track racing. The Reactiv Geometry is Inspyre's race-specific frame design, not a repurposed freestyle frame. The flip/flop rear hub is genuinely useful for newer riders: run it as a freewheel (one-way engagement like a normal bike) for racing, or flip it to fixed for training drills. The proportioned brake lever for smaller hands matters more than people think — a lever sized for an adult hand on a Mini-class bike makes braking harder and less controlled.
What size should I order?
Micro (15.75" TT, 18" wheels): riders under 3'8", approx. 3–5 years old. Mini (17.25" TT): 3'8"–4'2". Junior (18.75" TT): 4'2"–4'8". Expert (19.5" TT): 4'6"–5'0". Expert XL (20" TT): 4'10"–5'4".
