The bike is paid for and the guest is holding a phone. You have a route you like and about a minute to get it across. There are four ways shops actually do this, and they fail in different places. A GPX file The format a bike computer eats, and the right answer for a rider who asked for it by name. Export it, email it, and they load it onto a Garmin or into the app they already use. At a hire counter it is the wrong shape almost every time. The person who rented a town bike for four hours does not have a head unit in the basket, does not know what a GPX file is, and will not learn while you are holding their card. People search for how to print a GPX file, which is the sound of this mismatch. A link to a map Fast, free, and everybody understands it. Open Google Maps, drop the pins, send the link. How that line gets drawn is worth reading if this is your usual answer, because the default route is the quick one rather than the one you would send a family down. It breaks in three places. The line has no stops in your words, no photograph, and no reason to get off the bike. It does not survive the valley with no signal. And it is not yours: the day arrives in a browser tab with somebody else's brand on it. A photocopy Still the most reliable thing on this list, and no shop should be embarrassed about it. Paper does not run out of battery. It also cannot be corrected, cannot speak, gets wet, and tells you nothing afterwards. If the bridge is closed you are reprinting the stack. If they loved the ride you find out only if they come back in and say so. A code on the counter The guest points the camera they already use at a square by the till. Your tour opens in the phone's browser: your colour, your logo, the stops you chose, your sentence about each one, and the waiver if you use one. No app, no account, no club. You draw it once, on a Tuesday, and print one poster. Editing a stop does not mean reprinting the square, so the closed cafe is a one-line fix rather than a print run. What the guest sees is the order that screen unfolds in, and the QR itself is the square. What to do with the one you have None of this is an argument for throwing out the file you already made. Draw the route wherever you like, then decide separately how it reaches a stranger's phone, because those are two questions and shops usually answer them with one tool. If the ride goes somewhere with no signal, ask what happens when the bars drop. Offline maps for a hired bike is that question, answered for a guest rather than for a rider who planned ahead.
