sixthreezero Bike Size Chart

sixthreezero started in 2005 in Hermosa Beach, California, when Dustin Goldberg began selling cruisers out of a garage; the name nods to a Chicago 630 area code. The line is hybrid/cruiser and e-bikes, not race geometry. This page has sixthreezero’s hybrid chart. Many models are one frame with a long seatpost. Standover and saddle height matter more than an S/M/L road chart.

How to measure

Height filters the chart. Cycling inseam decides which overlapping size to keep. The method is the same for every brand.

Height and inseam

Height

Take shoes off and stand tall, looking straight ahead. A helper should rest a flat object on the crown of your head, then run a tape from the floor to the underside of that object. Save the number in inches and centimeters — charts use both.

Inseam

Stand tall and barefoot with feet slightly apart. Ask a helper to measure vertically from your crotch to the floor. Keep your legs straight and feet flat.

FAQ

  • What sixthreezero bike size do I need?

    Use your height on the Hybrid chart on this page. On the hybrid table, 152-165 cm sits in both 24" and 26". Cycling inseam and standover pick the side. Then check stack and reach for the exact sixthreezero model.

  • Does this sixthreezero chart apply to every model?

    It is a brand-level Hybrid starting range (24", 26" on this page), not a substitute for the current model-year chart. Geometry, wheel size, and cockpit can move the answer even when height matches a row.

  • Which sixthreezero sizes are listed on this page?

    The Hybrid chart on this page includes 24", 26" (122-193 cm on the hybrid table). Verify the current sixthreezero model chart on the official site before purchase.
