flexible bicycle stabilizers let children learn balance before losing the training wheels

baswil rethinks the role of training wheels

Baswil introduces a bicycle stabilizer that allows children’s bikes to lean before the support wheels engage. Designed for 12- to 16-inch bicycles, the system permits up to 15 degrees of lateral movement, departing from the rigid geometry of conventional training wheels.

The movement is made possible by a patented dual-blade mechanism formed from flexible technical plastic. As the bicycle tilts, the blades flex before gradually transferring weight to the support wheels, creating a softer intervention than the fixed geometry of conventional stabilizers. Baswil treats leaning as part of the riding experience, allowing children to pedal while becoming familiar with the subtle shifts in balance that accompany turning and steering.

A flexible support system instead of rigid wheels

The project centers on a patented dual-blade mechanism made from a flexible engineering plastic. A vertical blade attaches to the rear axle of the bike, while a horizontal blade rests against the rear fork, creating a structure that combines adjustability with controlled flexibility.

As the bicycle leans, the material bends progressively. Once the bicycle reaches approximately 15 degrees of lean, the support wheel contacts the ground, preventing a full fall while allowing the rider to experience the sensation of balancing through corners. At roughly one kilogram for the pair, the stabilizers are intended to minimize additional weight while fitting most children’s bicycles equipped with standard 9.5 mm rear axles.

Baswil fits most 12-, 14-, and 16-inch children’s bicycles and installs using a standard wrench in around five minutes. The kit includes two stabilizers, mounting hardware, and an illustrated installation guide. The adjustment process follows four steps: removing existing training wheels, attaching the vertical blade to the rear axle, securing the horizontal blade into the mounting rail, and fine-tuning the wheel height so both stabilizers contact the ground when the bicycle is upright.

Balance bikes have become widely accepted as an effective way for young children to develop coordination before progressing to pedal bicycles. Belgian startup Baswil targets children who are already able to pedal but still need assistance developing balance. The system combines both pedaling from balancing skills into a single learning process. According to the company, most children adapt within two to four weeks of regular use, although progress naturally varies between riders.
