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 Expert XL 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. 

Features
  • Pride Racing APEX fork. A pivot 1-1/8" fork with 10mm dropouts, matched to a semi integrated ZS44 headset running sealed bearings.
  • Shimano hydraulic disc brakes. The BL-MT401 right lever and BR-MT410 rear calliper on resin pads and a Forward 140mm rotor pull you up over the finish line.
  • 165mm cranks for Expert XL. SD B85 two piece cranks on a 4-bolt 104 BCD ring give a 41x16 gear, a 53.57" ratio for the age classes racing this bike.
  • Fastr X front, Powerblock rear. Tioga 20x1-3/8" tyres on double-wall Forward Joyride 28H rims, laced with stainless 14G spokes to sealed bearing Joyride V2 hubs.
  • 150 engagement point rear hub. The Forward Joyride V2 Disc cassette runs six pawls, so the drive picks up quickly when you stand on the pedals.

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.

Pro XXXL175 to 185cm and up22"
Pro XXXXL185cm and up22.5"
Cruiser (24" wheels)175cm and up21.5" and up

Heights overlap between bike sizes on purpose. If you fall in two size categories, a growing rider new to racing is usually better suited to the larger bike, a experienced rider who wants the bike to more responsive should err on the smaller size. 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. Just don't guess their height either, you know how fast they can grow!

Here are some tips

  • Between two sizes and still growing? Take the larger size, but make sure you check the top tube length of the bike. The length of top tube for a given size (Expert XL as an example) can vary up to a half inch or more across brands. Most Expert XL frames are 20", but we've seen them as long as 20.7"
  • Experienced racer and wanting the bike to be more responsive? Take the smaller size. You want the bike to be "under you", not a stretch to the bars and cranks.
  • Top tube is the number that actually changes the fit, so compare it against the bike they ride now.

Still not sure? We're the experts and size bikes for riders every day of the week. Our team has decades of experience between them and will help you decide which bike is the right fit based on rider height and racing experience.
