THE HIGGS CARGO

The Kei Truck of E-Bikes

Size is deceptive. The Higgs Cargo fits in a studio apartment hallway but hauls 440 lbs of life—more payload than our standard cargo model. This is industrial strength in a compact footprint. The 15.5-inch ultra-low aluminum frame with marine-grade bamboo decking and 20-inch fat tires delivers low-center-gravity physics that keeps you planted under load. Class 2 throttle means effortless hill climbing when fully loaded. IPX6 water-resistant battery handles rain, snow, and winter commutes. It's the density of capability that makes it the ultimate urban tool. No apologies. No wasted space.

KEY SPECS

WHO'S THIS FOR

Need to haul cargo in an apartment-friendly footprint? Want serious carrying capacity that actually fits your storage space? Looking for universal accessibility (15.5" step-over) paired with 440lb payload? Ready to replace car trips with a bike that fits where cars don't?

What you can do:

• Carry two passengers or massive cargo loads (up to 440 lbs combined)
• Cruise at 20 MPH throttle mode with complete cargo control
• Mount and dismount with ease in any outfit (15.5" ultra-low step)
• Handle hills with loaded cargo using 7-speed flexibility
• Ride 30–60 miles per charge on a single battery fill

TECHNICAL SPECIFICATIONS THAT MATTER

FROM PROBLEM TO SOLUTION

Chassis & Payload

440lb Compact Platform

The Higgs Cargo defies physics. It hauls more payload (440 lbs) than our standard cargo model—in a frame so compact it fits apartment living. This isn't bulk; this is density.

✓ 440lb Combined Capacity – Carry 2 passengers or haul a week's worth of groceries, camping gear, sports equipment—in a package that doesn't demand a garage.

✓ Ultra-Strong Aluminum Chassis – Marine-grade durability; engineered for structural integrity under load; compact construction doesn't mean compromise.

✓ Marine-Grade Bamboo Decking – Luxury material that looks premium and delivers natural grip; comfortable for passengers; durable in all weather.

Frame Geometry

15.5" Ultra-Low Entry

Universal accessibility isn't a luxury feature—it's engineering. The 15.5-inch step-over means anyone can mount and dismount with ease, even with cargo or passengers on board.

✓ 15.5" Step-Over Height – The lowest entry point in our cargo lineup; mount and dismount with dignity, in any outfit, any time.

✓ Compact Length (68 inches) – Fits in apartment hallways, studio storage, car racks; doesn't demand a garage or outdoor shed.

✓ Extended Running Boards – Bamboo-inlaid footrests; safe passenger mounting; comfortable seating for children or adults.

Powertrain

52V High-Torque System

When you're hauling 440 lbs uphill in a compact frame, the 52V system delivers. High-voltage efficiency engineered for cargo work—not play.

✓ 52V Advantage – High-voltage efficiency for cargo hauling; stronger acceleration than standard systems; hill-climbing muscle even when fully loaded.

✓ 750W Rear Hub Motor – Reliable, responsive torque delivery; tuned for cargo stability and control.

✓ 780Wh Capacity with IPX6 Rating – 30–60 mile range depending on load and terrain; water-resistant for all-weather reliability.

Water-Resistance & All-Weather Capability

IPX6 Battery System

This is the spec that transforms a cargo bike into a car replacement. The IPX6 water-resistant battery handles rain, snow, splashes, and winter commutes without flinching.

✓ IPX6 Water-Resistant Rating – Ride in rain, sleet, and snow without battery anxiety; no separate protection needed.

✓ Year-Round Reliability – Water resistance means consistent performance in all weather; winter commutes become viable.

✓ System Powered – Always charged; integrated with main battery; no separate management.

Drivetrain & Control

7-Speed Mechanical Advantage

The Higgs Cargo gives you gear range to find the perfect pedaling rhythm under load—especially crucial in compact cargo applications.

✓ 7-Speed Shimano Drivetrain – Flexibility to climb hills with 440lbs; ability to descend safely with cargo; pedaling efficiency on extended hauling days.

✓ Low Gear Ratios – Flatten inclines without battery drain; maintain power when fully loaded; preserve range on longer cargo runs.

✓ Smooth Transitions – Proven Shimano reliability; low maintenance compared to electronic shifting.

Braking System

4-Piston Heavy Duty

440 pounds in a compact frame demands commercial-grade stopping power. The Tektro 4-piston hydraulic brakes deliver.

✓ 4-Piston Calipers – Industrial-strength stopping power in wet, dry, and variable conditions; confidence at 20 MPH with full load.

✓ Hydraulic Modulation – Smooth, progressive braking; minimal hand effort required even with extended cargo weight.

✓ Safety First – Consistent performance whether cruising empty or descending with maximum payload; no fade under sustained braking.

Tires & Stability

20" Low-Gravity Base

The Kei Truck secret: smaller wheels sit lower to the ground, keeping your center of gravity planted under load. This isn't cute—it's physics.

✓ 20" x 4" Fat Tires – Lower center of gravity with cargo; exceptional grip on all terrain; compact footprint.

✓ Low-Center-Gravity Physics – Smaller wheels + extended wheelbase = stability even with maximum payload; vehicle-like planted feel.

✓ Mixed Terrain Capability – Gravel, sand, wet pavement, light trails—handles all surfaces with confidence.
