Two minutes with a wall

Measure it, do not remember it.

A height typed from memory is the single most common reason a bike goes back. Both numbers take a book and a pencil.

01
Shoes off, back and heels against the wallLook straight ahead, not up. Somebody else marks the wall at the top of your head — doing it yourself adds a centimetre every time.
02
Measure floor to mark. That is your heightThis is the number that rules a frame out.
03
Now the inside leg: a book, spine up, pulled up firmlyFloor to the top of the spine, shoes off. This is the number that decides between two frames when your height fits both — and the one nobody has to hand.
Why we ask for height and not inside leg first

Height is the number everybody knows, and it is enough to rule a frame out. Inside leg is the number that chooses between two frames that both fit — so it is asked second, and only when it matters.

Nothing you type here is sent anywhere. It is kept in this browser so the shop can answer with it, and clearing your browser clears it.

The three that need a person

Under, over, and exactly on the line.

Every shop has these three and most answer them one email at a time. They are printed here instead.

Under 158 cm

The K02 is the closest and you would be at or under its lower limit. We will not tell you it is fine from here — send your inside leg and we will say yes or no.

One reply, from somebody who rides them.
Exactly 178 cm

Both the K01 and the K02 fit, and the answer is not the number. It is whether you want to swing a leg over or step through.

The two frames, side by side.
Over 200 cm

The K03 has the longest reach in the line and it still runs out at 200. Above that, none of the three is right and we would rather say so.

Before you order, not after.
The second question

Step through it, or swing a leg over it.

At the height where two bikes fit, this is what actually separates them — and it has nothing to do with who the bike is “for”.

Step-through · K02 High-thru · K01
Getting on Step through the middle. Nothing to lift a leg over. Swing a leg over the saddle, as on any bike.
Stack 710 mm — more upright 840 mm — more forward
Best if You stop and start often, carry a child seat, or a hip or knee makes lifting a leg awkward You ride longer, faster, or off the road
Not so good if You want to get out of the saddle on a climb You are getting on and off twenty times a day

The catalogue calls one of these a women’s frame and the other a men’s. That is the industry talking, not the geometry: pick the one you want to get onto twenty times a day.

If it is still wrong

Two ways out, and neither costs you.

Fourteen days, collection included

We send the courier — you do not box a bike and drive it anywhere. It is the only honest answer to a bike nobody can sit on first, and we have no showroom to offer instead.

From the day it arrives.
Send two numbers, get one answer

Height and inside leg, and what you ride to. One reply, from somebody who rides them — not a form that comes back with a link to this page.

One working day.
