Gearing

Lower gears help on climbs. Higher gears suit higher speeds.

Published build36T · 14T · 1-speed

Ratio2.57:1

Speed unavailable: wheel or tire size is missing or unclear.

Add your rear tire size to calculate speed

How it works

Ratio = front teeth ÷ rear teeth. Hub gears also include the hub’s internal ratio. A 400% range means the highest ratio is four times the lowest.

Speeds are estimates from tire size and pedal cadence. Actual speeds vary.

Your changes apply to this calculation. The archived build stays unchanged.

Gears Drivetrain

Front teeth Smallest rear teeth Largest rear teeth

Use up to three front tooth counts, separated by /. For one rear sprocket, enter the same count twice.

Rear tire

Rear tire marking

Apply the marking on your rear tire or edit its dimensions below. Older or fractional inch sizes need the ISO marking (e.g. 37-590).

Rim diameter (BSD, mm) Tire width (mm)

For 32-622, width is 32 mm and rim diameter is 622 mm. Use the rear tire on mixed-wheel bikes. Leave both fields empty to compare ratios only.

Cadence (RPM) Speed units

Frame and fork

Inspect the frame and fork →

Archived: Frame: TIG-welded · Fork: · Hi-tensile steel/chromoly steerer, unicrown crown

Look for dents or shape changes and inspect the edges of welds around the head tube, bottom bracket, seat cluster and suspension mounts for hairline cracks.

Drivetrain

Check drivetrain wear →

Archived: Group: BMX · Crankset: 3-Piece Tubular Chromoly 140mm, 36 teeth · Bottom bracket: Loose ball w/ 8 spline · Cassette: Freewheel · Rear cogs: 1-speed, 14 teeth · Chain: KMC Kool Chain, 1/2 x 1/8"

Check chain tension and chainline, rotate the drivetrain through a full revolution and confirm the rear axle or tensioning hardware cannot slip.
Measure chain wear with a compatible gauge and inspect chainring, cassette or freewheel teeth. A new chain does not rule out wear in the remaining drivetrain.
Turn the cranks slowly, feel for rough bearings and check for side-to-side play. Inspect crank arms, chainring bolts and pedal threads for looseness or damage.

Brakes

Inspect the brakes →

Archived: Brakes: Tektro 907 U-brake rear brakes, Tektro 2 finger rear levers

Inspect pads and braking surfaces, check the complete cable or hose path, and confirm both controls feel consistent and return cleanly.

Wheels and tires

Check wheels and tires →

Archived: Wheel size: 16" wheels · Rims: Front: Alienation PBR Black, Rear: Alienation PBR, 32-hole · Hubs: Aluminum shell w/ 3/8" axle · Front tire: Front: 16 x 2.125" Kenda K-Rad, Rear: 16" Kenda Kontact

Spin both wheels and watch for side-to-side and vertical movement. Check spoke tension, rim condition and hub play.
Inspect both tire casings for cuts, cracking, plugs, bulges or exposed threads and confirm the installed sizes are safe for the rims and available frame and fork clearance.

Controls and contact points

Archived: Headset: 1 1/8" FSA Threadless · Handlebar: Hi-Ten 2-piece · Stem: Alloy 4-bolt · Seatpost: Steel micro-adjust, 25.4mm diameter · Saddle: DB Padded Jump · Pedals: Mini Alloy Platform

Apply the front brake and rock the bike to check for headset play or notchiness. Inspect the stem, handlebar and clamp zones, then confirm every fastener and control is secure.
Check that the seatpost moves for adjustment and that the saddle, post and clamp hold securely without cracks, severe corrosion or damaged hardware.
