PUKY LS PRO Flowmatic: Compare Automatic Gearing with the Standard 16
PUKY LS PRO Flowmatic adds an explicit two-speed automatic-gearing description to the comparison with the standard LS PRO 16. The saved standard record lists its freewheel and 28T/15T drive, while the 16-2 Flowmatic record separately names automatic gear changes. Matching tooth counts do not make those equipment descriptions identical.
Identify the PUKY LS PRO Flowmatic record
The Anthracite 16-2 Flowmatic source is article 00004502. Its gear-shift entry describes a two-speed automatic system that changes to second gear from approximately 8 km/h. The word approximately belongs with that statement; it is not a measured switching threshold established for an offered bicycle.
The 18-2 Flowmatic source, article 00004504, carries its own two-speed automatic and approximately 8 km/h description. Keep its 18-inch model identity when quoting it. A feature stated for two named records is stronger evidence than assuming that every similarly named PUKY has the same system.
Compare the gear-shift statement with the drive entry
The standard 16 and the 16-2 both list a freewheel and a 28T/15T drive. The Flowmatic page adds the automatic-gearing entry. The standard page does not supply a gear-shift field in its inspected equipment list; that absence should remain an observation about the record, rather than a claim to have inspected every internal component.
The saved Flowmatic wording establishes automatic gearshift or gearbox terminology. It does not establish a hub mechanism. This reference therefore avoids supplying an internal design, maintenance method or replacement identity from the familiar word automatic.
Choose the comparison question separately from size
The standard 16 and 16-2 records share 40–55 cm inseam and 100–120 cm height guidance. The automatic-gearing description does not establish a different fitting range in this pair. For the standard Ash Blue LS PRO 16, identify the appropriate size before asking whether the documented automatic alternative serves the rider’s needs.
No climbing, acceleration or riding test was performed here. These are the manufacturer records captured on 24 October and reread on 6 November 2026. Find wider context in PUKY Bikes and the existing introduction, keeping drivetrain and fitting questions distinct.
FAQ
Does a shared 28T/15T entry describe every gear function?
No. Flowmatic has a separate automatic-gearing statement in its record.
Is 8 km/h an independently measured result here?
No. It is the source’s approximate change-to-second statement.
Does the source establish an automatic hub?
No. The inspected wording establishes automatic gearing without that mechanism identification.
