Projeto Grau 2: How to unlock the ZJ6 and secret bikes

Updated: November 2026.

If you are cruising through the open-world streets of Projeto Grau 2, you know that having the right bike is everything. Whether you want to pull a flawless wheelie (the famous "grau"), outrun the cops during a high-speed chase, or just show off your customized ride to other players, your garage defines your status. The mobile hit from Insanity Group continues to dominate the charts, packed with an impressive roster of vehicles, dynamic weather systems, and an interactive job market. However, the community is always hunting for the most exclusive rides—the ones that aren't sitting on display in the main dealership.

Two of the most sought-after machines right now are the ZJ6 and the massive AT1100. These bikes offer top-tier speed, unique handling, and major street cred, but getting them requires knowing exactly where to look and what mechanics to use. Let's jump right into the step-by-step process you need to follow to park these two beasts in your garage today.

How to unlock the ZJ6 in the secret shop

The ZJ6 is basically an urban legend on the map, and a lot of players waste hours driving around trying to find it in the normal vehicle menu. It is simply not there. The developers hid it behind a specific requirement to reward the most dedicated explorers.

To unlock the ZJ6, you have to locate and access the MotocaLoko secret shop. This hidden vendor is the exclusive location where the bike is sold. The coolest part about the ZJ6 is its attention to detail: it comes with its own custom dashboard, a highly realistic exhaust sound, and the choice between keeping the stock exhaust or throwing on a loud sport pipe that echoes through the city streets.

Before taking your new prize to the streets, you will want to drop by the game's official workshop to fine-tune it. There, you can adjust the suspension for better balance during wheelies, change the tires for improved grip, or even customize the paint job. Just remember that the ZJ6 alone will attract plenty of police attention due to its speed and sound, so make sure your handling skills are sharp before you start taunting the patrol cars.

How to unlock the AT1100 step by step

While the ZJ6 is hidden behind a secret shop, getting your hands on the AT1100 requires a bit more active exploration. The latest updates introduced a really fun scavenger hunt mechanic to the open world that takes advantage of the game's verticality.

Here is the exact step-by-step process you need to follow to claim the AT1100:

• First, make sure you are in a safe spot away from traffic or police. Pull up your in-game cell phone and open the DRONE application.
• Start flying the drone around the city map. The controls are responsive and allow you to gain significant altitude. Use this to your advantage to get a bird's-eye view of the city blocks.
• Pay close attention to rooftops, construction areas, and weird corners that you cannot normally reach on foot or by bike.
• You need to find exactly 5 hidden keys scattered across the area. Hover over them to register the collection.
• As soon as you successfully collect all 5 keys, the game will notify you, and the AT1100 will unlock automatically in the main vehicle store.

Once it is unlocked in the store menu, you have two options: you can either buy it outright using your hard-earned in-game cash, or you can rent it for a limited time by watching a quick advertisement. Renting is a great way to test the bike's massive power before committing your funds.

Making money: Chop shops, the Rolo app, and new missions

Unlocking these secret bikes is only half the battle; you still need the cash to buy and upgrade them. If you prefer the honest route, the game offers plenty of legitimate work. You can clock in as an electrician, chop wood as a lumberjack, or take on endless delivery driver missions. These provide a steady, safe income.

But if you want fast money to afford the ZJ6 or AT1100 immediately, the latest updates added some very profitable (and highly illegal) new hustles to the city.

The Rolo app on your in-game phone is your gateway to the black market. This app lets you sell stolen bikes directly to specific buyers who place orders for certain models. Alternatively, you can take undocumented, hot bikes to the chop shop (desmanche). Once inside, you can use a blowtorch to break the bikes down and turn them into instant cash for parts.

If you choose this dangerous path, you must watch out for GPS trackers hidden on the stolen bikes. If a bike is tracked, open your backpack, equip the Alicate do Motoca (mechanic's pliers), take off the seat, and quickly cut the tracker wire before the police pinpoint your exact location. The cops are much smarter in recent patches; they will not just chase you, but they will actually set up cone roadblocks at intersections to take you down. Stay alert, plan your escape routes, and ride fast.
