Description

The Inspyre EVO range of bikes are gaining traction with racers both at the start of their BMX racing journey, to those that are giving it a red hot crack. This French brand knows a thing or two about designing race winning geometry, as well as bringing great value to race bikes in a competitive market. 

The Inspyre Evo-C Disc Junior 2025 bikes are ready to race straight out of the box, at any level from a club night all the way to the national championships. With a suite of aftermarket parts from component brands like Pride (for the carbon forks) to Forward, SD and Tioga providing a mixture of bars, stem, cranks, hubs, rims and tyres. 

The frame is manufactured from premium aluminium 6061-T6 with hydroformed tubes that are triple butted. The dropouts are swell forged 3D aluminium. What does this mean? The frame is comparable to any aftermarket frame, with the dialled in race geometry. Shimano hydraulic disc brakes help pull you up as you blaze over the finish line. 

Over the past few years, the Inspyre EVO-C bikes have been one of our best selling race bikes across all sizes, from the junior right up and through the pro sized bikes, with the cruisers being super popular with mums and dads returning to racing.

Assembly information

Your bike ships mostly assembled in the box. Finishing it takes most people 10 to 20 minutes with basic tools, and the video above walks through every step.

  • Fit the handlebars and line them up with the front wheel
  • Fit the front wheel, pedals and seat post
  • Check the brakes and tyre pressure before the first ride

Tools: Allen key set and a 15mm, 17mm or 19mm spanner for the pedals and axle nuts (bikes can vary between these three sizes). A socket is needed if installing pegs.

Rather have it done? Ask us about extra assembly before you order, or any local bike shop can finish the build for a small fee.

BMX race bike sizing

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

SizeRider heightTop tube
Micro (18" wheels)Under 120cm16.25"
Mini (20" wheels)110 to 140cm17 to 18"
Junior120 to 150cm18.25 to 18.75"
Expert130 to 170cm19.5 to 19.75"
Expert XL145 to 170cm20 to 20.75"
Pro150 to 175cm20.25 to 20.75"
Pro XL165 to 180cm21 to 21.25"
Pro XXL170 to 185cm and up21.5 to 21.85"
Pro XXXL175cm and up22"
Pro XXXXL180cm and up22.5"
Cruiser (24" wheels)175cm and up21.5" 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.
