Visual Weight Dial
FLYBIRD adjustable dumbbells are designed with a concise and clear dial, which helps shorten the time for changing weights between sets during training.
There are 5 weight gears: 5 Ib, 10 Ib, 15 Ib, 20 Ib, and 25 Ib.
Safety Lock
The safety lock design makes sure the weights can only be adjusted on the tray.
During lifting, the buckle structure on the weight plates will lock the plates, ensuring that they do not fall off.
Space Saving
Are you still worried about not having enough space to store a whole lot of dumbbells?
Now, with the Flybird adjustable dumbbells, you don't even need more than 10 square foot.
The trays come with great tensile and compressive strength, more than enough to hold the dumbbells safely in a small space.
1-Second Weight Change
