At GoBabyGo, we believe every child deserves the freedom to move, explore, and experience independence. The Core Build Kit is our open-source effort to share the core components and lessons from years of building customized electric cars for children with disabilities.
This kit reflects over a decade of iterative learning, hands-on problem-solving, and feedback from hundreds of families and builders. Our mission is to make adaptive ride-on vehicles simpler, more consistent, and easier for other GoBabyGo chapters, makers, and caregivers to replicate and customize.
💡 The kit is built for collaboration. Whether you're improving it for your local chapter or adapting it to new use cases, we welcome your ideas and contributions.
We replace foot pedals with accessible hand- or head-activated push buttons. The kit includes:
- A no-solder generic pedal-to-jack adapter
- Modular push button mounts for off-the-shelf (e.g., Logitech Adaptive Kit) and custom buttons
- Stable, flexible mounting connectors for various control schemes
- Mods and Extentions models for different use cases.

Standard seat belts rarely meet the needs of children with disabilities. Our approach:
- Wide, adjustable belts with printed mounts and tri-glide adjusters
- Low-profile mounts for use with adaptive bike seats and close-fitting car frames
- Headrests
- Lap boards
- External support structures
Currently supporting 20mm PVC parts for building lightweight but sturdy.
A robust, customizable switch (65mm) designed for adaptive electric cars, toys, and gaming environments. It offers enhanced stability, tactile feedback, and compatibility with common low-profile mechanical keyboard switches.
- X/Y Stabilization — Reduces wobble, improves actuation consistency
- Swappable Springs — Adjustable actuation force for different users
- Snap-In Mounting — Supports common low-profile switches (Gateron, Kailh)
- Child-Friendly — Durable with engaging tactile response
- Logitech Gaming Kit Compatible — Includes mounts for Logitech large buttons
- JellyBean-Style Cap — Transforms switch into a classic accessible form

All printed parts are designed with accessibility and ease-of-use in mind. We recommend:
- PETG filament for safety and durability
- 0.35 mm layer height for most parts, 0.2 mm for fine details.
- Mounts designed for M3 screws or zip-tie options
Crafted by the Israeli chapter of GoBabyGo — Over the course of building ~800 adapted vehicles, we realized the value of consistency, modularity, and collaboration. The Core Build Kit simplifies complex adaptations without sacrificing the flexibility needed for each unique child. Our long-term vision is to see this kit evolve as a community tool—shared, improved, and loved by chapters and makers worldwide.
