Why This Three‑Wheeled Beast Matters
When the road ahead melts into gravel tracks, sandy creek beds, or pothole‑spattered city backstreets, most cargo bikes start to flinch. The Greattan D Cargo eTrike doesn’t. It laughs—then rolls forward on a pair of seven‑inch rear fat tires that look ripped from a lunar rover, ready to carry half a quarter‑ton of whatever life throws on its rack.
Muscle Where It Counts
Addmotor planted a 750 W rear‑drive motor (1,400 W peak) deep in the triangles, paired it with a torque sensor for smooth launches, and capped the party at 20 mph to stay street‑legal. Seven levels of pedal assist keep your cadence civilized; a half‑twist throttle is there for that “get‑me‑home‑now” kick. Opt for the dual Samsung battery setup and the downtube plus seat‑tube combo turns distant errands into miniature expeditions—no range anxiety in sight.
Stability: Engineered, Not Guessed
Torque is nothing without control, so the Greattan D adds a speed differential for calm cornering and a 20 % thicker rear axle built to laugh off a full 500 lb payload (350 lb rider + 150 lb cargo). Front‑fork suspension, a padded saddle with backrest, and those cartoon‑size tires soak up the chatter while Tektro mechanical discs—and a parking brake—put a hard stop to downhill surprises.
Everyday Utility, Extraordinary Range
That cavernous rear basket swallows grocery hauls, toolboxes, or a campsite’s worth of gear. Commuters slash fuel costs. Urban couriers multiply drop capacity. Weekend explorers bolt on a cooler and disappear until the map ends. The Greattan D Cargo eTrike isn’t just transport; it’s a blank check for creativity.

Verdict: Built for the Bold
If your daily orbit involves oversized loads, unpredictable surfaces, or the urge to roam beyond the grid, the Greattan D Cargo eTrike is the rare machine that says “yes” to everything at once—power, traction, stability, and sheer hauling swagger. Strap down the cargo, twist the throttle, and watch the horizon move aside.
Pros
- Monstrous 7‑inch rear fat tires deliver unstoppable traction on sand, gravel, and pot‑holed asphalt, turning sketchy shortcuts into smooth sailing.
- 500‑lb total payload (150 lb cargo + 350 lb rider) means you can haul groceries, tool chests, or a weekend’s worth of camping gear without breaking a sweat.
- Dual‑battery option (UL‑certified Samsung packs) doubles range potential, letting you roam far beyond the city limits before hunting for an outlet.
- 750 W rear‑drive motor peaks at 1,400 W and pairs with a torque sensor, serving up silky launches and confident hill climbs even when fully loaded.
- Speed differential and a 20 % thicker rear axle keep the trike planted in corners and impervious to frame‑twist under heavy cargo.
- Front‑fork suspension, padded backrest saddle, and those balloon‑size tires soak up chatter, making rough roads feel like fresh tarmac.
- Tektro mechanical discs, parking brake, and an integrated 5‑in‑1 lighting system (with turn signals) layer on real‑world safety touches.
- Shimano 7‑speed drivetrain plus seven‑level pedal assist let riders fine‑tune effort—cruise leisurely or mash the throttle when deadlines loom.
- Pre‑order pricing undercuts the final MSRP, giving early adopters a solid discount on a premium hauler.
Cons
- Curb weight tips the scales at 143–154 lb, which is a beast to muscle up stairs or onto roof racks when the batteries are drained.
- Top speed is limited to 20 mph—street‑legal, yes, but slower than some Class 3 e‑bikes and pace‑mashing delivery trikes.
- Dual‑battery upgrade tacks on another $699, nudging the fully‑loaded price well north of four grand.
- Tektro mechanical discs lack the bite of hydraulic brakes, demanding more hand strength, especially on long downhill runs with max cargo.
- Overall width (32.7 in) and length (77.1 in) can make tight urban bike lanes, elevators, or crowded storage rooms a logistical puzzle.
- Manufacturer hasn’t published real‑world range figures, leaving riders to guesstimate mileage—critical intel for couriers and commuters.
- Assembly and maintenance of a trike with differential, dual batteries, and fat‑tire wheels can intimidate DIY newcomers and inflate shop bills.
Verdict
The Greattan D Cargo eTrike is a swaggering pack mule disguised as a three‑wheeled tank—ideal for riders who covet boulder‑proof tires, brutal hauling capacity, and the confidence of a torque‑sensing motor. It’s heavy, pricey, and capped at a conservative 20 mph, but if your day (or business) revolves around moving big payloads across unruly terrain with zero drama, this machine earns its keep. For city commuters with cramped storage or speed demons chasing 28 mph thrills, look elsewhere; for everyone else who wants to trade the van keys for electric freedom, the Greattan D delivers.
$3,799
If the Greattan D feels like a lumbering cargo juggernaut, the ENVO Flex Trike is its nimble, shape‑shifting cousin—lighter on the wallet at $2,699 yet heavy on versatility. A Canadian‑built, foldable aluminum frame pairs with a step‑thru design and telescopic bars, so riders of every stature hop on without theatrics, then stow the rig in a city apartment or van when the day’s done. Its 500 W hub motor hustles up hills while fat 20‑inch tires iron out gravel, snow, or cobblestones; swap in the optional dual‑battery setup and you’re talking up to 200 km of range—triple the reach of many bulkier trikes. Disc brakes on all three wheels clamp down with surgical precision, LED lighting keeps night rides honest, and modular components let you morph the Flex into a sleek urban runabout when cargo duty ends. For riders who crave freedom, portability, and genuine all‑terrain swagger without dragging an extra 60 pounds of steel, the ENVO Flex Trike is the smarter, more adaptable way to haul and explore.
