PUKY LS PRO Gearing: Read Both Tooth Counts Before Comparing with SKYRIDE
PUKY LS PRO gearing can be recorded more precisely than a front chainring number alone. The saved LS PRO 16 drive entry gives 28T/15T, while YOUKE 12 gives 28T/14T and SKYRIDE 20-3 gives 38T/19T. Keep each pair with its model before comparing the complete bicycles.
Record both sides of the PUKY LS PRO gearing entry
The LS PRO 16 Ash Blue example connects to manufacturer article 00004501 and its 28T/15T drive statement. YOUKE 12’s common 28T first number does not make its separate 14T second number disappear. A shortened comparison that lists only 28T would hide a published difference.
The pair identifies a different part of the drivetrain record from a gear-shift description. It should stay attached to its own source field instead of becoming a claim about every internal ratio, the condition of a used drivetrain or the suitability of a replacement part.
Read the SKYRIDE hub statement alongside its tooth pair
SKYRIDE 20-3 separately lists 38T/19T, a three-speed hub gear and Freewheel Yes. Those are distinct entries. The 38/19 pair is not a list of the hub’s three internal ratios, and this source comparison does not supply those missing ratios.
That makes a useful purchasing question: which published numbers describe the external drive, and which describe the gear system? Keeping the headings avoids treating a two-number tooth entry as though it were a complete account of a multi-speed mechanism.
Include wheel information before discussing rollout
The LS PRO 16 wheel rows identify 16 inches at front and rear. SKYRIDE 20-3 identifies 20 inches. Tooth counts alone cannot establish equal distance travelled for a pedal revolution across differently described wheel arrangements, let alone a result for a particular rider or hill.
No cadence, climbing or speed test has been performed here. Nor does a matching tooth count establish chain, mounting or component compatibility. If an offered example differs from its original description, record the fitted parts rather than selecting a more convenient catalogue row.
The records were captured on 24 October and reread on 6 November 2026. The brand introduction gives the family context, and the PUKY topic keeps related equipment references together.
FAQ
Do LS PRO 16 and YOUKE 12 share the complete tooth pair?
No. Their second numbers are 15T and 14T respectively.
Does 38T/19T list all SKYRIDE internal hub ratios?
No. The three-speed hub statement is separate from that drive pair.
Do the tooth counts alone predict climbing ability?
No. They do not establish a complete bicycle-and-rider performance result.
