bikzerStep-through does not mean one size fits all
A low frame makes getting on and off easier but does not guarantee the right saddle height or reach. Check the minimum and maximum saddle positions, the cockpit and the manufacturer’s height range. The same step-through design may be offered in several sizes.
Match the position to your journey
Short trips with frequent stops and longer rides place different demands on your position. Check that you can look ahead and use the brakes naturally. A raised or swept-back handlebar changes posture, but it should not disguise a frame outside your suitable range.
Try everyday manoeuvres
In a safe space, practise starting, braking and stopping. If you plan to carry panniers, check heel clearance and follow the rack’s fitting limits. Set the saddle for pedalling: being able to place both feet flat on the ground while seated is not a universal adult sizing requirement.
Frequently asked questions
What does one size mean?
It means the manufacturer offers one frame size, not that it suits every rider. Check its height range and adjustment limits.
Can I use this chart for a folding bike?
Use the folding model’s own guide. Seatpost and handlebar extension ranges and folding mechanism limits are especially important.
Does a 28-inch wheel identify my size?
No. That wheel format can appear on different frame sizes. Check frame geometry separately.
