Engineering & Innovation
The technical platform behind every UPT vehicle.
Five granted patents. Four independently controlled in-wheel motors. A modular UL 2271 battery you can swap in seconds. The UPT is the first electric chassis designed to be reconfigured, and engineered so the same parts work whether you're spec'ing a quad, a cargo bike, or an autonomous delivery vehicle.
Engineering philosophy
Built for mass customization. Engineered for safety, longevity, and serviceability.
Most EV platforms are designed for one vehicle. UPT is designed to become many. Shared components. Hot-swappable batteries. Standardized T-slot mounting across the entire chassis. Five patented technologies. A platform that's quick to assemble, simple to service, and ready to scale anywhere in the world.
Patented innovations
Four engineering breakthroughs that make modularity work.
ENVO has filed for five patents covering the UPT platform's modular four-wheeler architecture, in-wheel motor, modular battery system, steering mechanism, and flat suspension.
Proprietary in-wheel motor design.
Four independently controlled hub motors, one per wheel, with no traditional drivetrain consuming chassis space. IP67 sealed for water and dust, regenerative braking on every wheel, and individual traction control that adjusts thousands of times per second. Maintenance-free, drivetrain-free, and the foundation of UPT's tank-turn and all-wheel traction capabilities.
Modular UL 2271-certified battery architecture.
Eight 690 Wh modular battery packs (5.5 kWh total) that swap individually. Replace a depleted pack mid-shift instead of waiting on a charge. Upgrade battery capacity without replacing the chassis. The same battery system scales from a city commuter to an off-road utility vehicle, and is built to UL 2271 safety certification.
Flexible, offset-able steering mechanism.
Proportional steering with adjustable handlebar position and offset-able steering column. Configure the steering for stand-up operation, seated operation, side-by-side seating, or a centered riding position, without changing the chassis. The same patented mechanism supports tank-turn, crawl, and high-speed driving modes.
Flat double-wishbone suspension.
A patented double-wishbone design with 120 mm of travel and two modes, Urban (firmer, paved-surface optimized) and Off-road (softer, longer travel). The flat suspension profile keeps the chassis floor flush, enabling pass-through cargo, low step-in seating, and modular upper-body configurations that aren't possible on a traditional 4-wheeler.
Chassis & drive features
Engineered to be reconfigured.
Drive modes (Eco / Standard / Performance)
Choose the right power curve for the application. Eco for range, Standard for daily use, Performance for off-road or load conditions. All controlled by the dual-core 240 MHz VCU.
FWD / RWD / 4WD selectable
Front-wheel for tight maneuvering, rear-wheel for efficient cruising, all-wheel for traction. Switch from the console, no mechanical drivetrain to engage, just electronic torque distribution.
Tank-turn capability
0 m turning radius in Tank-Turn mode. Reverse one side's motors and pivot in place. Indispensable for warehouse aisles, hospital corridors, and hairpin trail turns.
T-slots across the entire frame
Standardized T-slot extrusions across the chassis. Mount cargo racks, sensors, equipment, attachments, or upper-bodies with off-the-shelf hardware, no custom fabrication required.
All-wheel ABS + regenerative braking
Hydraulic disc brakes on all four wheels with ABS, plus regenerative braking that recovers energy back to the battery during deceleration. E-Brake included for parking and emergencies.
Crawl & cruise control
Crawl mode for low-speed precise positioning (loading, terrain crossing, tight maneuvering). Cruise control for highway-stretch on-road segments. Both managed by the VCU.
Adjustable wheelbase + track
Wheelbase from 1120 mm to 1370 mm; track at 850 mm or 1135 mm. Configure for stability (wider track, longer base) or maneuverability (narrower track, shorter base), same platform.
Foldable bumper + bumper racks
Pass-through foldable bumper racks for long items. Foldable front bumper for compact storage. 3,000-lb winch-capable heavy-duty chassis end bracket for towing and recovery.
