Yes. Postbound runs free in any modern browser on desktop, tablet or phone, with no download, no install and no account. Optional short videos can be watched for extra coins or turbo, but the whole fifty-leg campaign can be finished without watching any.

There is one input: hold anywhere on the screen, Space, or a gamepad button. Holding on the ground drives and lifts the front wheel; letting go settles it. In the air, holding tips the nose up and releasing lets it drop, which is how you land level. A double-tap spends a turbo once you have unlocked it. There is no steering and no brake.

Because holding the button on the ground lifts the front wheel — that is the same reaction torque that makes a real bike wheelie. It is useful for clearing a bump and dangerous on a climb. Let go for a moment to drop the nose, then get back on it. The lift is capped, so a wheelie on its own will not flip you; a wheelie into a bump will.

Fuel only drains while you are holding the button, so coasting downhill costs nothing. There are fuel cans on the road that top the tank back up, and taking the line that collects them is a real decision rather than free money. If the tank empties and the trike comes to a stop, the leg ends where you are and you still collect coins for the distance you covered. A Bigger tank upgrade extends it, and every vehicle carries a different amount.

It is the endless mode, unlocked after you clear the third region. One road with no post box at the end: the hills get steeper and the obstacles get closer together the further you drive, and the only thing keeping you going is the fuel cans on the verge. Your score is the distance, and your best is kept alongside your campaign progress.

Yes, once you buy the Toolkit in the garage. It covers one crash per leg — flip it, get stuck or drop into a gap and you are set back on your wheels a few metres behind instead of the run ending. It does not cover running out of fuel, because putting you back on the road with an empty tank would not help.

Yes, and not just in top speed. The Hauler tows a second body on a real link — it swings, pushes you on descents and can fold. The Scooter is light with high torque, so it lifts the nose far more easily than the Trike, which helps in the air and hurts on a climb. They change how you use the one button rather than how fast you finish.
