Best Electronic Groupset for Folding Bikes 2026: WHEELTOP EDS TXF Guide

Quick answer: the WHEELTOP EDS TXF is a wireless 1x groupset for folding and flat-bar bikes. It supports 7–14 speed, with an alloy 58mm short cage (up to 32T, any wheel size) or a Carbon Ceramic oversized pulley long cage (up to 36T, 20″ wheels or larger). There is no shift cable to kink when the bike folds.

Why Wireless Suits a Folding Bike

On a folding bike the rear shift cable bends every time you fold. With wireless shifting there is no rear shift cable, so folding does not affect shifting.
