Engineered for builders.
Ready for the road.
Simplified EV conversions with precision-built, modern systems.
Tested by pros, trusted by DIYers.
Start Your Build 
We’re kicking things off with four cornerstone components — thoughtfully engineered, currently in development, and built to set a new standard in EV conversion.
Each product reflects our long-term commitment to quality, reliability, and the builder experience.
Every component is crafted with purpose — combining premium engineering, modern technology, and real-world builder insight.
Formosa kits are intuitive, frustration-free, and ready to go.
Only 100% new, OEM-grade components.
Engineered to work with your setup, not against it
