Description

When I started riding BMX in 2007 my first bike was a 2007 Fit PRK bike, it didn't come with sealed hubs, and weighed 16 kgs. This year Fitbikeco’s PRK bikes don't just weigh 4 KGs less but they feature lower standovers, responsive modern geometry frames and sealed bearings all around from wheels up. Fit Bike co PRK forks are responsive with 25mm offset drops and feature a longer 172mm steerer tube for use with a GYRO. Slightly lower 8.7in bars match perfectly with the taller GYRO stack height and top load forged FIT stem. Other notable features on 2023 PRK’s include smaller 160mm cranks on the 20” TT, and slightly longer 165mm cranks on the 20.5TT.

Coming in 4 colours that will have you standing out at the skatepark these bikes are the perfect step up off that entry-level pushie you have been fixing for the last 6 months!

Fitbikeco’s PRK bikes feature frames with lower stand-overs, short chain-stays and a middle of the road 75.3 head angle that’s maneuverable but stable when blasting transitions. PRK forks are responsive with 25mm offset drops and feature a longer 172mm steerer tube for use with a GYRO. Slightly lower 8.7” bars match perfectly with the taller GYRO stack height and top load forged FIT stem. Other notable features on 2023 PRK’s include smaller 160mm cranks on the 20” TT, and slightly longer 165mm cranks on the 20.5” TT.

• All PRK models come with GYROS
• Flanged Savage grips
• Linear brake cables
• Frame size specific crank lengths

Features

Gyro fitted as standard. Every PRK comes with a sealed brake detangler and linear cables, so barspins are sorted before you leave the shop.
Modern park geometry. Lower standover, 12.6" chainstays and a 75.3° head angle: manoeuvrable, but stable when you blast transitions.
Sealed bearings from wheels up. Fit S1W sealed hubs front and rear, a sealed 9T cassette and a sealed mid bottom bracket.
Frame specific crank lengths. 160mm cranks on the 20" top tube and 165mm on the 20.5", so the fit suits the rider, not just the frame.
Under 12.5 kg either size. 12.29 kg for the extra small and 12.42 kg for the medium, on 2.4" Fit OEM tyres with flanged Savage grips.

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.

Top Tube Length - 20

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 height	Wheel size	Top tube
60 to 91cm	12"	12 to 12.5"
81 to 106cm	14"	14 to 14.5"
96 to 122cm	16"	16 to 16.5"
122 to 147cm	18"	18 to 18.5"
147 to 157cm	20"	19.75 to 20.25"
157 to 168cm	20"	20 to 20.5"
168 to 175cm	20"	20.25 to 20.75"
175 to 183cm	20"	20.5 to 21"
183 to 190cm and up	20"	20.75 to 21.5"
160cm and up	22"	21 to 22.25"
160cm and up	24"	21.75 to 22"
160cm and up	26"	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.
