That is a vendor claim about assembling the platform—not evidence that a complete, tested, road-ready and registered car can be built in 60 minutes. Bodywork, safety equipment, validation and approval are separate parts of a finished vehicle project.
What is the TABBY EVO?
TABBY EVO is an open-source, modular electric-vehicle development platform from OSVehicle, now presented by Open Motors. It is a configurable chassis and component system rather than necessarily a turnkey finished car. Open Motors makes 2D and 3D design files available and publishes a specifications and bill-of-materials brochure. The company identifies the TABBY design as licensed under Creative Commons Attribution-ShareAlike 4.0 International; anyone reusing covered work should follow its attribution and share-alike terms.
The platform is intended to let builders develop a vehicle around a common base. Open Motors lists two-seat and four-seat configurations, with final bodywork and equipment affecting the result. A community project in Rennes reports that its group discovered Tabby in Shenzhen in early 2015 and built two TABBY EVO vehicles with the OSV team; that history demonstrates community builds, not a controlled test of the one-hour claim. The project links community resources, including 3D models, at OSV in Rennes.
What does “assembled in 60 minutes” mean?
Open Motors’ TABBY EVO platform page promotes the platform as “TABBY EVO in just 1 Hour,” while its product page describes assembly in less than an hour. The company says the platform is designed for seamless assembly and presents this as assembly of the modular platform. The claim is not an independently verified build-time measurement.

It should not be read as a promise that a builder can design and fit bodywork, add all required safety systems, test the vehicle, obtain approval and register a road car in that time. Those steps depend on the finished design, the builder’s work and applicable local rules.
What is included, and what must a buyer confirm?
Open Motors describes packages that can include the chassis, suspension, steering, brakes, wiring, battery system, motor, controller and charger. The exact contents depend on the selected configuration, so the listing is not a guarantee that every package contains every component in the same form.

The vendor describes a welded and screwed steel-tube chassis, McPherson suspension, front-wheel drive and front and rear disc brakes. Its displayed configuration lists an AC asynchronous motor rated at 19 kW and a 24-cell LiFePO4 battery pack rated at 82 V and 12.8 kWh. The product page also offers selectable configurations; confirm the precise battery, powertrain, components and vehicle category for the specific order.
- Ask for an itemized list of included and excluded parts for the chosen two-seat or four-seat configuration.
- Confirm whether the quoted package includes the battery, motor, controller, charger, wiring and any required mounting or body components.
- Ask the seller to confirm current price, shipping, taxes, lead time and any support or documentation supplied with the order.
Published dimensions and performance figures
The following figures are Open Motors’ published specifications, not independent real-world test results. The company says bodywork and final configuration affect performance; the platform-only speed and range should not be treated as guaranteed figures for a completed vehicle.

Open Motors’ FAQ also describes 19 kW and 15 kW motor variants and says the 15 kW version is intended for the European L7e category. The company notes that seat count can affect the vehicle category. These are vendor explanations, not a substitute for checking current classification and requirements with the relevant authority in the country where the vehicle will be used.
Is the TABBY EVO street legal?
Not automatically. Open Motors says TABBY versions are supplied without seatbelts, airbags and ABS because those choices affect the final vehicle design. Its platform page also says a roll-bar is not included and that other mandatory safety systems depend on the customer’s design. Although the product page describes certified, road-legal components and structural design, approval applies to the completed custom vehicle—not simply to the platform or the fact that particular parts are certified.

Before building for public-road use, identify the vehicle category and approval route for your location, then verify that the proposed finished design and its equipment meet those rules. Requirements can differ by country and category; the two-seat and four-seat layouts may not be treated alike. Do not assume a platform specification, vendor description or component certificate establishes that a particular finished TABBY EVO can be registered.

Who is TABBY EVO for?
TABBY EVO is most relevant to builders who want a documented, configurable EV platform and are prepared to make decisions beyond assembling the base. It is not a shortcut around the work of selecting a configuration, completing the vehicle and meeting local approval requirements.
If you are comparing it with another chassis or kit, compare what is actually sold—not just headline performance or assembly time:
- Whether the offer is a bare platform, a component package or a finished vehicle.
- Seat count, dimensions, weight and payload.
- Motor, battery, speed and range figures, including the conditions under which performance is stated.
- Included safety equipment and the scope of any certification or approval.
- Availability and license terms for design files and documentation.
- Price, shipping, support and the local registration pathway.
Those distinctions matter more than the one-hour headline: it describes the manufacturer’s intended assembly of the modular platform, not the time needed to turn it into an approved road vehicle.
