I'm designing a repairable Low-speed Electric Vehicle for Real Roads.
This low-speed electric vehicle (LSEV) is designed for repair, not replacement. Designed with rural roads, small workshops, and off-the-shelf parts in mind, it reimagines mobility through the lens of accessibility, modularity, and right-to-repair.

This project isn’t about sleek city EVs—it’s about vehicles you can fix with a socket wrench and a neighbor, adapted to small farms, towns, and folks who keep things running long after warranties expire. I’m building from the ground up with transparency, sustainability, and collaborative design at the core.

I’m sharing everything I learn—what works, what fails, and what sparks new questions.

Heartland EV is a modular, repairable low-speed electric vehicle (LSEV) designed for rural roads, small farms, and communities that rely on self-reliance. This is a vehicle that prioritizes fixability over polish, and transparency over closed ecosystems.

The goal: Build something that can be repaired in a barn, not replaced in a dealership.

Technical Focus

  • Chassis: Designed for modularity and off-the-shelf parts
  • Steering & Suspension: Tuned for low-speed, uneven terrain
  • Frame Materials: Prioritizing weldable, repair-friendly materials
  • Power System: Exploring low-voltage, swappable configurations
  • Open Source: CAD, design notes, and build logs all shared here

Why It Matters

  • Many EVs are sealed, complex, and fragile—this is the opposite.
  • Rural communities need vehicles that are adaptable and serviceable.
  • We believe in the right to repair, and this project lives it out.
  • This isn’t a concept car—it’s a field tool with soul.

Collaborators Welcome

  • Looking for a Collaborator – 3D Modeling for Modular, Repairable EV

    Jeremy06/29/2025 at 00:59 5 comments

    I'm developing Heartland EV, a modular, open-source low-speed electric vehicle designed to be assembled, fixed, and adapted in a barn, not a dealership.

    The goal: a repairable EV platform for rural mobility that prioritizes right-to-repair, accessibility, and swappable utility modules.

    I’ve laid the groundwork—concept sketches, basic frame ideas, early design research—and now I’m looking for someone skilled in 3D modeling or CAD to help take the prototype to the next level.

    If you’re excited about designing for sustainability, real-world utility, or community-driven hardware, I’d love to collaborate. Open-source values, iterative thinking, and good vibes welcome.

    Project Log #1: From Idea to Action – Launching this Low-speed Electric Vehicle Project

    This is where the wheels hit the dirt.

    This project began as a simple question: Can we design an electric vehicle that doesn’t just work, but lasts, adapts, and invites you to fix it yourself? Not a sealed pod from a showroom, but a machine that could be built in a barn, repaired with a socket wrench, and shared with your neighbors.

    What’s Been Done So Far

    • Defined the Vision: A modular, repairable low-speed EV for rural roads—built around accessibility, sustainability, and the right to repair. 
    • 3D Modeling: Created an early frame prototype and multiple swappable utility kit concepts to explore modular configurations.
    • Created the Collaborator Interest Form: Here’s the link if you're curious—designed to attract values-aligned contributors. 
    • Refined Project Messaging From name brainstorming to clarifying tone, we've carved out a voice that blends freedom, resilience, and community-first design.

    What’s Next

    • Begin publishing early chassis sketches and component lists
    • Share progress on steering and frame material decisions
    • Engage the Hackaday community through the messaging room and the first wave of updates
    • Iterate design publicly—celebrating both breakthroughs and stumbles

    Why This Matters

    • So many vehicles are built to be disposable. This one won’t be.
    • This project is about taking mobility back into our own hands—building machines that reflect our values, support our communities, and hold the kind of dignity that doesn’t come off an assembly line.
    • If you’re into repair culture, open hardware, or building for places that most tech skips over, you’re in the right place.

    Build Instructions (Early Prototyping Stage)

    This project is still in the early prototyping phase, but here’s the rough order of operations:

    1. Chassis Design & Frame Prototyping — Modular base frame using weldable square tube — CAD in progress; early sketches shared in Files section
    2. Steering & Suspension System — Designed for low-speed, uneven terrain — Using off-the-shelf parts
    3. Utility Module Development — Multiple modular kits (cargo, truck bed, coup) — Swappable based on use case
    4. Powertrain & Electrical Planning — Targeting 48V golf cart motor configuration — 48V Prismatic Cell LFP Battery pack, focused on safety + maintainability
    5. Field Testing + Iteration — Designed for rural roads, short commutes, farm utility — Expecting lots of revision (and learning!)

    > ⚠️ As this project evolves, instructions will become more detailed and include CAD files, wiring diagrams, and fabrication tips. Stay tuned!
