LIGHTWEIGHT

The perfect bike for young explorers aged 7-11 years old or between 125-150cm tall. Whether tackling light trails or cruising through the park, this lightweight (11.6kg) alloy bike is built for fun and confidence.

SMOOTH RIDING

The 40mm suspension fork, specially tuned for lighter riders, soaks up bumps and vibrations, providing a comfortable ride for young adventurers.

ROOM TO GROW

FRAME FEATURES

A replaceable derailleur hanger and protective cage keeps things running smoothly even after those inevitable tumbles. While the included kickstand and water bottle mounts make it convenient for everyday use.

EASY PEDALLING

The 7-speed drivetrain with short cranks makes pedalling comfortable and efficient for young legs, while the intuitive trigger shifter with an optical gear display makes gear changes a breeze.

Big bike upgrade for my 8 (almost 9) year old son.

Great experience. The bike looks great and the parts appear to be high quality and the same brands as some more expensive bikes. The first few rides were a little challenging due to the height increase from his previous very small bike. He really enjoys it now and it looks like it will serve him for a while. I'm tempted to find a bike here for myself now.

Greatly Exceeded Expectations

Was hesitant to buy online, and was incredibly pleased with the Polygon Premier. It's an awesome bike, and my daughter loves it! It arrived quickly, was packaged very well, and was assembled in roughly 10 minutes. I'm buying all our future bikes from bikesonline.

Excellent Bike For My Daughter!

My daughter is so hyped for this bike! It’s a big upgrade from her little LOL Surprise bike. She now asks, “Dad, can I go ride my bike? I’m craving my bike.” The bike shipped fast, it was easy to put together, it’s got a solid construction, it looks super-cool, and it’s very lightweight compared to a steel equivalent. I’m very happy with this choice and so is my daughter.
