14 inch bike gearing: compare tooth counts before ranking ratios
14 inch bike gearing is not fully described by the words single speed. The two Kross LIFTIE records both list one gear, yet their rear tooth entries differ: fifteen for mint and ten for blue. The GB woom GO 2 record goes further by giving eighteen teeth at the front and ten at the back.
Build a 14 inch bike gearing comparison with two tooth counts
For GO 2, dividing the stated front count by the rear count gives eighteen divided by ten, or 1.8. That is arithmetic from the published tooth entries. It is not a measured road speed, a climbing result or a promise about how easily a child will pedal.
The Kross pages provide only part of that calculation. Each says SINGLE and lists one gear. Mint's rear entry is 15T; blue's is 10T. Their crankset entries identify aluminium without publishing a front tooth count in the inspected specification blocks.
| Recorded bicycle | Front teeth | Rear teeth |
|---|---|---|
| woom GO 2, GB record | 18 | 10 |
| LIFTIE mint | Not supplied | 15 |
| LIFTIE blue | Not supplied | 10 |
A shared rear number does not establish a shared ratio
Blue LIFTIE and GO 2 each have a ten-tooth rear entry, but that supplies only one side of a comparison. Without the blue bicycle's applicable front count, the GO 2 ratio cannot be transferred to it. Similarly, the fifteen-tooth mint entry does not by itself establish which complete build has the lower ratio.
Ask a supplier for the front and rear tooth counts together, attached to the exact model. If the answer concerns a replacement drivetrain, keep it separate from the original archive. This is a comparison of documented builds, not an instruction to exchange sprockets or create a new gearing combination.
Separate the number of gears from the brake arrangement
The GB GO 2 drivetrain text explicitly says there is no coaster brake. That is a separate statement from its tooth counts. One gear alone does not answer the brake question, and customer comments concerning another market do not amend this GB technical entry.
The Kross LIFTIE 14 Mint Matte listing identifies configuration OS (7") 14". Include that configuration in a gearing enquiry so the response remains tied to the mint offer rather than a generic fourteen-inch bicycle. The manufacturer article for its mint record is KRLFXX14X07U009304.
Complete 14 inch bike gearing notes identify the source, both tooth counts where available and the actual offered model. Explore the 14-inch bicycle category or read the woom range introduction for broader context.
FAQ
Do both LIFTIE records list one gear?
Yes. Both list one gear, alongside their different rear tooth entries.
Does a ten-tooth rear entry prove an identical ratio?
No. The applicable front tooth count is needed as well.
Is the GO 2 calculation a speed test?
No. It is the quotient of the two published tooth counts.
