>>1670703>affordable 26 inch foldableBuy a Montague-like frame from Ali (should cost you around $100-150) and a donor bike locally depending on your budget. Bam, cheap foldable. Grease up the hinge, change the skewer to something high-quality for peace of mind (it has to be closed very tight on these) and it will serve you well enough. Thin tires make it fold better (do as I say, not as I do).
