Description

Want to hit the track with the kids on one of the best race cruisers on the market? The Radio Helium Pro 24 Cruiser has a 22 inch top tube to give this race bike plenty of stability, which will help keep you out of the emergency department and up on the podium. Taking the top of the line Radio Helium 24 inch frame and adding a swathe of Radio Raceline parts has produced, at this price point, 2021's best valued race cruiser.

Running 180mm Radio Raceline, Xenon Pro 2pc cranks, the power is transfered through to a fully sealed Radio Xenon hub, and onto the track via the tried and trusted Tioga Powerblock 1.60 tyre.

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.

Mini (20" wheels)110 to 140cm17 to 18"
Junior120 to 150cm18.25 to 18.75"

Expert XL145 to 170cm20 to 20.75"
Pro150 to 175cm20.25 to 20.75"

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.
