Bike repair online booking: the grey next button

The bike type question sits near the top of most bike repair forms, and it decides what comes next. A rider with an e-bike, a folding bike or a cargo bike looks for their bike and finds nothing close. They pick other, and a text box appears that wants a make or a description. If the box is empty, or the rider types a character the form does not expect, the next button stays grey. Nothing says why. The rider tries the button again, then tries another shop. The owner tested with a road bike and never saw the grey button.

• Is there an e-bike or a folding bike in the bike type list, or only road and mountain?
• After you pick other, does a field appear with a line saying what to type?
• With the next button grey, is there a message near the field that says what is missing?
• Can you move through the form with the Tab key on a laptop and reach the next button?
• On a phone, does the next button stay visible while the on-screen keyboard is open?

Once the bike type is chosen, the rest of the booking often changes. A road bike may skip a question about tire width, while an e-bike may ask for a battery check or a service the shop only offers on certain days. When the list has no match, the form has no path to follow. The owner sees a tidy dropdown and assumes riders will find their bike. Count the bike types on your list, then compare them with what riders actually bring in. Add the common ones that are missing, even if the service is only a basic check, so the form has a route for them.

A grey button is a state, not an answer. The rider does not know which field is holding it. To find the cause, open the booking on your own phone and walk the form. Pick other, leave the text box empty, and try the button. Then type one word and try again. If the button comes alive only after the box has text, the form needs an answer it never explains. Next, walk the same path with a laptop keyboard. If the Tab key moves past the field without landing on it, a rider who cannot tap will not get through either. Write down the field where the button changed state.

A rider with a flat and a rider booking a full tune-up meet the same form, and it has to tell them apart. If every service asks for a drop off day, a rider who needs a tube swapped sees a wait they did not expect and leaves. Compare the service list with the time list. Each service should say how long the shop keeps the bike before the rider picks a time, and that wait should match what the shop actually does.

The first run finds the field. The fix adds bike types, a text box or a message under the button, and a later edit can undo any of them. Walk the same e-bike rider through after each change, then a road bike rider, so the common path still works. Repeat it when you add a service or change the drop off days, since one small change to a list can disable the button for every rider with that bike.
