Size chart and fit guide for 2026
Continue researching this bike brand
MarKnig is an Amazon-direct budget brand that sells a tiny, focused lineup: two 700C road bikes and one 26" hardtail mountain bike, all built around a single-frame, adjustable-fit philosophy. Every model uses one frame size for riders 5'2"-6'0" with quick-release seatpost and adjustable handlebars - so sizing is by rider height, not by labelled S/M/L. Maximum rider weight is 330 lb across the lineup.
