Description

Every detail of the 2026 STR from FIT - frame, fork, components, and even the paint has been purpose-built for the streets. The geometry includes a short rear end, taller standover height, and a steeper head angle, all dialled for modern street riding. Removable brake mounts and cable guides offer clean lines, while the fork features a tight 25mm offset and peg clearance cuts for precision control.

The STR rolls on FIT’s 2.4” F/U tyres and a double-wall rear wheel, allowing riders to run lower tyre pressures for better grip and smoother landings. Four-piece bars, flangeless CrossFIT grips, and four metal pegs come stock—clear indicators of the bike’s street-first intent.

Available in two top tube sizes and clean, straightforward colourways, the STR is ready to deliver when the Streets Are Shouting.

Features
  • Purpose built for the street. Short 12.6" rear end, taller standover and a steeper head angle, with a Cro-Mo front triangle to take the punishment.
  • Clean lines, nothing in the way. Thread-on brake mounts and removable cable guides strip off, and the fork runs peg clearance cuts with a tight 25mm offset.
  • 2.4" tyres, double wall rear. FIT F/U 2.4" tyres on a double wall rear rim let you drop the pressure for more grip and softer landings.
  • Four metal pegs come stock. Four 100mm pegs are fitted from new, so the bike is ready to grind the day you wheel it out.
  • Street first cockpit and cranks. Four-piece 9" x 29" bars, flangeless CrossFIT grips and tubular Cro-Mo 165mm cranks driving a FIT alloy 25T sprocket.

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.

20 inch BMX sizing

A 20 inch bike is the standard adult BMX and suits riders from about 147cm up. At this wheel size the top tube is what changes the fit, so pick that by height.

Rider heightWheel sizeTop tube
60 to 91cm12"12 to 12.5"
81 to 106cm14"14 to 14.5"
96 to 122cm16"16 to 16.5"
122 to 147cm18"18 to 18.5"
147 to 157cm20"19.75 to 20.25"
157 to 168cm20"20 to 20.5"
168 to 175cm20"20.25 to 20.75"
175 to 183cm20"20.5 to 21"
183 to 190cm and up20"20.75 to 21.5"
160cm and up22"21 to 22.25"
160cm and up24"21.75 to 22"
160cm and up26"22 to 23"

Sizes overlap on purpose, so personal preference comes into it. If you land in two bands, riding style breaks the tie: longer for flow, trails and transitions, shorter for technical street and park.

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.

Top tube is measured from the centre of the seat tube to the centre of the head tube, so it is not the same as the length of the tube you can see.

  • A 20 inch bike is the standard adult BMX and most riders end up there, so do not size a tall child down to a smaller wheel.
  • 22, 24 and 26 inch bikes are adult bikes with a bigger wheel, not bigger frames for taller riders.
  • Size up for stability through trails and transitions. Size down if you want the bike quick and twitchy for spins and grinds.
  • Top tube is fixed, but stem length, fork offset and bar position all shift how roomy the bike feels once you are on it.

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