First of all, it’s important to mention that this particular FLYBIRD dumbbell set includes only one adjustable dumbbell with its tray, not two. Although it is a selectorized dumbbell, it features a different design than the YPC 90 lbs dumbbells, or the Bowflex SelectTech 552. It’s not a super expensive dumbbell, and you’ll basically get 5 dumbbells of different weights in one.

Key Features and Specifications

  • Dimensions: 14.6L x 7.9W x 6.7H inches (37L x 20W x 17H cm)
  • Weight range: 5 to 25 lbs (2.2 to 11.33 kg)
  • Adjustment increments: 5 lbs (2.26 kg)
  • Weight settings: 5
  • Accessories: Storage and adjustment tray

Dumbbell construction

The FLYBIRD 25 lbs dumbbell features a metal and plastic construction. Its handle is made of durable aluminum alloy which can hold the weight plates with no problem. Its grip has a convex shape for improved ergonomics. It also features several knurled areas for improved contact.

The weight plates are also made of metallic alloy (steel or aluminum, not specified). All of them are fully covered by a thick layer of durable thermoplastic material (probably polypropylene). Evidently, this type of construction comes with a series of advantages and disadvantages. To begin with, since they are selectorized, you can easily change weights without the usual loading and unloading of plates that is characteristic to standard cast iron plates. With a simple handle twist, you can pick up the desired weight.

Second of all, since the weight plates are fully covered by non-metallic material, they cannot catch rust and you won’t have to deal with a persistent paint smell that is specific to some dumbbells with painted weight plates. But on the other hand, just like any other selectorized dumbbells, these are more fragile. Differently put, if you drop them, there is a chance the weight plates will sustain damage and they won’t attach to the handle anymore. Of course, with proper care and use, this shouldn’t happen.

Another important aspect that we must mention here is that the FLYBIRD adjustable dumbbell is pretty large. It is slightly larger than a classic dumbbell with cast iron plates or fixed heads of the same weight. It is 14.6″ (37 cm) long, 7.9″ (20 cm) wide, and 6.7″ (17 cm) high of the ground. This may be a bit of an inconvenience for a small person, especially if they want to use two dumbbells for a horizontal chest press. But on the other hand, the dumbbell is actually 5 dumbbells in one.

It’s also important to mention that due to this construction, the weight plates do not spin on their handle. They also hold together pretty tight, so they won’t wobble or move when you exercise.

Adjustment system

The FLYBIRD 25 lbs adjustable dumbbell features a twistlock adjustment system. The weight selector is basically the handle. You simply place the dumbbell in its tray making sure that the plates are correctly aligned in their slots, twist the handle and choose the desired weight, and lift the dumbbell up. The handle should pick the corresponding number of plates to the selected weight.

Unlike the Bowflex adjustable dumbbells, the FLYBIRD dumbbell can only pick the same number of plates on each side. When you twist the handle, it will select the same number of plates on each head. Therefore, you won’t be able to create an off-set weight. This shouldn’t be a major inconvenience, though.

The dumbbell has 8 weight plates. Each one weighs 2.5 lbs (1.1 kg) while the handle weighs 5 lbs (2.26 kg). Therefore the adjustment increments are 5 lbs (2.26 kg) and the pre-determined weights are 5 lbs (2.26 kg), 10 lbs (4.5 kg), 15 lbs (6.8 kg), 20 lbs (9.0 kg), and 25 lbs (11.3 kg).

Accessories

The FLYBIRD 25 lbs dumbbell does not include too many accessories. The only notable one is the adjustment tray. This is pretty necessary to the quick and hassle-free weight adjustment because it keeps the weight plates aligned and tight so you can quickly twist the handle and select the desired weight.

The tray is made from the same sturdy thermoplastic material as the casings of the weight plates. It offers a pretty high tensile and compressive strength, so it should hold one dumbbell with no problem. It is not meant to support the user’s weight though, during dumbbell push-up exercises, though. In fact, dumbbell push-ups are not recommended for any selectorized dumbbells.

The Pros

  • Space-saving – 5 dumbbells in one;
  • Sleek design which can serve as a motivation factor;
  • Selectorized adjustment system great for quickly changing weight;
  • Decent weight range (from 5 lbs to 25 lbs);
  • Excellent micro-adjustability – 5 lbs (2.26 kg) adjustment increments;
  • No manual plate loading and unloading hassle;
  • Convex and textured handle for a comfortable and secure grip;
  • Sturdy handle made of aluminum alloy;
  • Storage tray included.

The Cons

  • Slightly larger than a standard dumbbell of the same weight;
  • Fragile – dropping it may break the weight plates.

Summary

The FLYBIRD 25 lbs weight set includes one adjustable dumbbell with its tray. This dumbbell features a twistlock handle adjustment system, a weight range from 5 lbs to 25 lbs, and adjustment increments of 5 lbs. It covers 5 separate dumbbells and can help save some storage space. And finally, it is more affordable than other selectorized dumbbells with the same range.
