Made by Engine Room

Built by a boxing gym.

Bag Engine comes from Engine Room VR in Tulsa, Oklahoma, the team behind the Engine Room boxing gym and Golden Gloves VR. We design and assemble every Engine here, and the same Engines count punches on our gym floor every day.

FAQ

Questions before you buy.

Will it work on my bag?

Bag Engine is made for hanging heavy bags. The strap goes around the bag near the top, above where you punch.

Which phones work?

The Bag Engine app runs on iPhone (iOS 16.4 or newer). Android is planned; there is no date yet. The Engine counts and shows your punches on its own screen with or without the app.

Is there a subscription?

No. Counting, your workout history and the app come with the Engine and stay that way, with no monthly fee. If we add optional extras later, they will be separate and optional.

How does it charge?

USB-C, from any phone charger. The cable comes in the box.

How do pre-orders work?

You pay $149 today, pick your color at checkout, and your Engine ships with free US shipping. The first 100 orders ship on or about November 15, 2026; orders after that go into the next run, and we email the ship date as soon as it is set. You can cancel for a full refund any time before it ships; if a date slips, we tell you right away and the same offer stands.

When does it ship?

The first 100 orders ship on or about November 15, 2026, later orders in the next run. We email you the tracking number the day yours goes out. US addresses only for now.

What about returns and warranty?

Send it back within 30 days of delivery for a full refund, for any reason. One-year warranty on the Engine: if it fails in normal use, we repair or replace it. Write to support@boxingengine.com.
