Bike description

The ultra-light balance bike BikeUP 12 is designed to make it as easy as possible for children to start their cycling journey. Thanks to its low weight and well-thought-out geometry, it enables natural and stable movement, helping kids quickly gain confidence, balance, and a smooth transition to a pedal bike. The low step-through frame makes mounting and dismounting easy, while the optimized riding position supports proper posture and efficient push-off. Children intuitively develop basic cycling skills without the need for training wheels.

The balance bike is equipped with a practical kickstand that simplifies everyday use - no more leaning it against walls or leaving it on the ground.

How to tell whether the bike fits

1 If they can't ride yet

The minimum saddle height decides. Seated on the lowest saddle position, the child must reach the ground with both feet flat. Its inseam must therefore be at least the minimum saddle height.

2 If they already ride

The stand-over height decides. Standing over the frame in front of the saddle, both feet must be flat on the ground with at least 2 cm to spare. It no longer needs to reach the ground from the saddle — the saddle goes higher so the leg is almost straight.

How to measure the inseam

The one number you need. You compare it with the bike's measurements.

How to measure the inseam
inseam
  1. 1

    Stand the child with its back to a wall, in the shoes it will ride in, feet together.

  2. 2

    Put a book, spine up, between its legs and press gently — as if it were sitting on the saddle.

  3. 3

    Measure from the top of the book to the floor. That is the inseam.

Compare it with the bike's measurements

If the child is still learning, the inseam must be at least the minimum saddle height — so it reaches the ground flat-footed from the saddle. If it already rides, it only needs to be at least 2 cm more than the stand-over height.

If the size doesn't fit, we swap it free within 7 days — you only pay the courier.

I really like the staff's attitude—they're very accommodating. We rent bikes for our grandchildren, who come to visit from abroad, and we really appreciate this service. Even after a year of doing business with them, I have no complaints.

Mám rada prístup zamestnancov, ktorí sú veľmi ústretoví. Biky požičiavame pre našich vnukov, ktorí prichádzajú zo zahraničia a veľmi oceňujeme tuto službu. Nemám k dnešnému dňu čo vytknúť ani po roku spolupráce.

My son loved the Foxie 12; everything was great as far as I'm concerned. We've just traded it in for a bigger one, and now we're going to teach him to ride the Foxie 14.

syn byl nadšený z Foxie 12, za mě vše skvělé, teď proběhla výměna za větší a budeme jej učit jezdit na Foxie 14.

I recommend them. It was the best decision for us. The only slight downside I see is that the balance bikes don't have brakes on the wheels. When the kids ride downhill, they can go very fast and have to brake with their feet. But otherwise, I recommend them. They’re beautiful and functional.

Odporúčam. Za nás najlepšie rozhodnutie. Možno trosku minus vidim v tom, ze na odrazadlach nie su brzdy na kolesach. Ak idu deti dolu kopcom vedia ist velmi rychlo a brzdia len nôžkami. Ale inak odporucam. Su krasne, funkcné.
