Quick Summary
The Nook Hack bike frame bag is a waterproof-style cycle bag with a touch screen phone holder on top. It is made for carrying a phone plus small riding essentials, with quick release fitting and access to a rear opening for a portable charger.
The bag combines phone viewing with storage in one unit, so it suits buyers who want a handlebar or frame-mounted option rather than a separate phone mount and bag.

What to Compare Before Buying
- Mounting position: This bag is described as fitting on the bike frame or handlebar. Check that the intended position suits your bike and does not interfere with steering or other accessories.
- Phone size and access: The touch screen cover is described as compatible with most mobile phones. Check that your phone fits comfortably inside the holder section.
- Storage needs: Compare the available pocket space with the items you want to carry, especially if you plan to keep tools, snacks or a charger inside.
- Weather protection: The bag is water resistant rather than a fully submersible case. If you need stronger rain protection, compare that requirement carefully.
What Else You May Need
If you plan to charge a device while riding, you will need a portable charger with a suitable cable. Check that the charger and cable suit the device you want to power.
Before You Decide
Confirm the mounting position, your phone size and the amount of storage you need before choosing an offer. If wet-weather protection is important, remember that this bag is not intended for long submersion or torrential rain.
