20 Inch Bike Gear Range: Liftie Seven-Speed and Hexagon Six-Speed Share 14–28T

2026-11-07

A 20 inch bike gear range comparison changes when two bicycles have different gear counts but the same published rear endpoints. Kross lists seven gears for the Liftie 20 X and six for the Hexagon Mini 1.0, yet both current specification tables print 14–28T. The extra position does not, by itself, establish an easier lowest gear.

20 inch bike gear range: count the positions and record the endpoints

The Liftie description calls its drivetrain 1x7. Its table names a Shimano Altus RD-M310 rear derailleur, Shimano M315 shifter and Sunrun FW-7I rear cluster. The Hexagon description says 1x6, with a Shimano Tourney TY200 rear derailleur, RV200 shifter and Sunrun TSFL-6I entry.

Those are two documented equipment packages. Seven and six describe the listed numbers of gears; 14–28T identifies the printed smallest and largest rear tooth counts. Neither page supplies the complete sequence of intermediate sprocket sizes. Do not invent that sequence to explain how closely spaced the steps will feel.

The missing front tooth count matters

Both descriptions identify a single-front-ring arrangement, but their inspected specification tables name crank materials without giving the front chainring's tooth count. That leaves a gap in a complete gearing comparison. Matching rear endpoints cannot establish that the easiest complete ratio is identical, and seven positions cannot establish that the Liftie has a lower one.

Ask for the front tooth count and the actual fitted rear cluster before requesting a complete ratio comparison. If a seller supplies different information, keep its model and component identity attached to the answer. A photograph of an unfamiliar bicycle is not a reason to fill a missing specification from appearance.

Turn the comparison into a useful enquiry

The Liftie 20 X catalogue entry provides a concrete seven-speed example. Describe your question as a comparison of its complete gearing with the six-speed Hexagon, rather than asking which has “more climbing gears.” Requesting the intermediate tooth sequence separately also makes clear whether the concern is total range or the spacing between available positions.

Wheel category is only one part of that enquiry. The 20-inch topic groups relevant listings, while the Kross introduction places the families in context. Neither supplies the front tooth count missing from these inspected records.

FAQ

Does seven-speed automatically give a lower bottom gear?

No. Compare the actual front and rear tooth counts; the number of selectable positions alone cannot answer that question.

What rear endpoints do these two pages publish?

Both print 14–28T, despite their different six- and seven-speed descriptions.

Are all the intermediate sprocket sizes known?

No. The inspected tables do not enumerate them. Obtain the exact cluster specification before comparing the steps or choosing parts.
