Your child rides free

The world's first autonomous speed governor for toddler balance bikes. Safety without sacrifice.

The Problem

70%
Toddlers lack grip strength for manual brakes
$1.2B
Annual market for balance bikes
Parent anxiety on hills

Current solutions (helmets, knee pads) only protect after the crash. There's no technology that prevents the crash by limiting speed.

The Solution

Automatic Actuation

Engages only when speed exceeds safe walking pace. No batteries, no sensors, no parent intervention required.

Maintenance-Free

100% passive system. No friction pads to wear, no cables to fray, no batteries to charge. Install once, forget it.

Universal Fit

Replaces your wheel spacer in seconds. Compatible with 95% of existing balance bikes and manual wheelchairs.

Beyond Balance Bikes

Manual Wheelchairs

Autonomous speed control for safer downhill navigation. Reduces caregiver anxiety and enables independence.

Light E-Mobility

Scalable to e-scooters and micro-mobility devices. A new category of passive safety.

Patent Protected

Proprietary technology with international filing strategy. Your competitive moat.
