Gearing

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

Pedal cadence

RPM

Speed units

RPM = pedal turns per minute.

Published build28T · 10T · 1-speed

Ratio2.80:1

Estimated speed At 90 RPM Gear14.9 mph

Rear tire: 20×1.95.

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.

Full used-bike inspection guide →

Frame and fork

Inspect the frame and fork →

Archived: Frame: TIG-welded · Fork: · Unicrown

Check paint damage, vent holes and accessible internal surfaces for corrosion. Look for dents, bent tubes and cracking around welded or brazed joints.

Drivetrain

Check drivetrain wear →

Archived: Group: BMX · Crankset: Free Agent 3-pc Chromoly, 28 teeth · Bottom bracket: Mid BB · Cassette: Cassette driver · Rear cogs: 1-speed, 10 teeth · Chain: KMC Z410, 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 FX-340 U-brake rear brakes, Tektro XL-320 alloy rear levers

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

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.

Archived: Headset: 1 1/8" Cane Creek A-head Zero Stack · Handlebar: Free Agent Jump · Stem: Free Agent Jump Alloy · Seatpost: Free Agent Alloy, 25.4mm diameter · Saddle: Free Agent Jump · Pedals: VP-568 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.
