## Customer Reviews

### ⭐ Not worth to buy for kids
*by J***N on September 1, 2026*

Two months. The left pedal fell off. So disappointed

### ⭐ Heavy
*by R***L on December 29, 2025*

Heavy bike, not lightweight at all.

### ⭐⭐ Very heavy for an "ultralight" small-kid bike
*by K***S on August 19, 2025*

The product description calls this "ultra-light" and "lightweight", using words like "magnesium" to reiterate the fact that this is meant to be a very light weight bike, suitable for 3+. This is exactly why i bought it for my soon-to-be 6-year-old: he's a small kid who needs a light bike to get away from training wheels. Unpleasant surprise: the bike weighs more than 22 lbs! My kid's toes couldn't touch the ground. There are other variants of this bike, perhaps similar or lighter, but there was nothing light about this particular bike. 22lbs puts it on the heavier side of similar-sized bikes that don't make claims about their magnesium frames. The brakes, too, were a bit too wide, making them hard to grasp with small hands - and therefore pretty dangerous for a novice bike rider. In summary, this is a poor choice for a first-time learn-to-ride bike, especially for smaller kids. On the upside, the quality seemed solid, with nice, durable-seeming parts and extremely painless assembly. We're returning this one and continuing our search for a true lightweight bike.
