A cargo e-bike program starts with the load, not the bike. What the vehicle carries decides where the cargo sits, how many wheels it needs, how much torque pulls it away from a stop, and how much battery a shift requires. That is the working method of a custom cargo e-bike manufacturer: engineer backwards from the mission. JOBO's cargo family demonstrates the approach in three architectures — a front-loader with the cargo in the rider's sightline, a long-tail with twin batteries for delivery routes, and a three-wheeled cargo tricycle with a differential motor for the heaviest duty — all built in the same Jinhua factory, with a second assembly site in Poland, inside a full-range lineup that also covers city, folding, mountain and motorcycle platforms.
Start With the Load: The Cargo Brief
Every serious cargo program opens with the same five questions, and a custom cargo e-bike program turns the answers directly into specification:
- What does a loaded shift look like? Parcel boxes, tools, groceries, passengers or mixed — the cargo's shape and weight set the layout.
- Where does the cargo sit? In front (visible, quick access), behind the rider (flexible, low-cost) or between three wheels (stable at standstill).
- What does the route demand? Gradients, stop frequency and daily distance decide motor torque and battery architecture.
- Who services it? Fleet duty means battery swap schedules, brake wear and component standardization.
- What does the market allow? Speed class and certification follow the destination market's rules.
Answer those five and your custom cargo e-bike stops being a guess — the three JOBO architectures below become assignments.
Three Architectures, Three Missions
Three JOBO platforms map onto the three load profiles a custom cargo e-bike brand is asked to serve.
The Front-Loader: Cargo in the Rider's Sightline
The JOBO Front Cargo E-Bike (JB-TDN47Z) is the most direct custom cargo e-bike layout: the load sits up front and low, with a 48V 500W motor, a 48V 15Ah LG battery, and a loading system rated at 130kg (95kg cargo + 35kg rider) on a low step-through 6061 aluminum frame. The small 20-inch front wheel with a 26-inch rear keeps the cargo platform's center of gravity low, so the bike stays predictable when fully loaded through tight streets. The rider sees the cargo — the reason front-loader layouts dominate urban delivery and tradesman use.
- Motor: 48V 500W
- Battery: 48V 15Ah LG, 50km range
- Load system: 130kg (95 cargo + 35 rider)
- Layout: front platform, low step-through, 20″ front / 26″ rear wheels
- Stopping: Tektro mechanical disc, Shimano 7-speed
The Long-Tail: Range for Delivery Routes
The JOBO Long Tail Electric Bike (JB-TDN79Z) carries behind the rider on an extended rack, and its headline specification is operational, not cosmetic: a dual-battery system (2 × 48V 15Ah, LG or Samsung cell configurations) delivering 120km of range — a full delivery shift without a mid-route charge. A 48V 350W hub motor with torque sensor, Shimano 8-speed, hydraulic disc brakes and 20×3.0 CST reflective tires make it the flexible custom cargo e-bike: goods on panniers today, a child seat and groceries tomorrow.
- Motor: 48V 350W hub, torque sensor
- Battery: 2 × 48V 15Ah (dual bays), 120km range
- Layout: extended rear rack, 20×3.0″ tires
- Stopping: hydraulic disc, Shimano 8-speed
The Cargo Tricycle: Stability at Standstill
The JOBO Cargo Electric Tricycle (JB-TDT18L) is the heavy-duty end of the custom cargo e-bike range. A 48V 1000W brushless differential motor drives the rear wheels, fed by a 48V 52.5Ah lithium battery refilled by a 48V 20A charger in 110–220V markets. Three wheels mean the vehicle stands upright loaded — no kickstand dance with 100kg of cargo — and the hydraulic braking system includes a parking brake for loading on grades. Modular cargo configurations (open bed, box, custom builds) let the same chassis serve municipal, agricultural and last-mile duty, and the LCD color display with USB carries your logo on its boot screen.
- Motor: 48V 1000W brushless differential
- Battery: 48V 52.5Ah lithium, 48V 20A charger
- Layout: three wheels, modular cargo configurations
- Stopping: hydraulic brake with parking brake system, 7-speed

How the Load Sets the Specification
The engineering chain behind every custom cargo e-bike runs in one direction — from the load down:
- Payload sets frame and brakes. A 95kg cargo rating is not marketing; it is a frame stiffness target, a fork rating and a brake spec. The front-loader's rating appears on its compliance paperwork, not just its brochure.
- Route sets motor and battery. Stop-start gradients need torque off the line (500W front-loader); long flat shifts need capacity (dual-battery long-tail); heavy duty cycles need both (1000W differential trike). A custom cargo e-bike program matches the powertrain to your route profile, not to a spec-sheet race.
- Duty cycle sets charging. The trike's 20A charger and the long-tail's second battery bay exist because fleet vehicles charge between shifts, not overnight. Battery architecture is scheduling hardware.
- Fleet operation sets the electronics. For shared and rental cargo fleets, the same custom cargo e-bike platform accepts IoT integration — GPS positioning, geofencing, remote lock control — under your own backend, the white-label approach JOBO applies across its fleet platforms.
- Your brand sets the surface. Display boot screens, frame color, cargo box livery: on a working vehicle, branding travels through the city all day.
One Factory Behind Every Architecture
Front-loader, long-tail and tricycle roll out of the same engineering system: a 50,000 m² plant in Jinhua plus a 10,000 m² site in Poland, 300,000 units of annual capacity across the full JOBO range, 107 patents, an R&D team of 40+ engineers, and ISO 9001 / CE / EN15194 certification with exports to 80+ countries since 2014. Cargo is one branch of that catalog — the same B-end program structure behind every custom cargo e-bike order also covers the folding family and the city commuter lineup in our earlier guides.
FAQ
How much weight can a cargo e-bike carry?
It depends on the architecture. JOBO's front-loader is rated for a 130kg load system (95kg cargo + 35kg rider); the long-tail carries flexible rack loads over its 120km range; the cargo tricycle is configured per mission with modular beds and boxes for the heaviest duty. A custom cargo e-bike program fixes the rating from your load profile before anything else.
Front-loader or long-tail — which layout should a delivery brand choose?
Front-loader if couriers load and unload constantly and need the cargo in sight at stops; long-tail if the priority is route length and load flexibility. The long-tail's dual batteries cover a full shift, while the front-loader's low center of gravity wins in dense stop-start traffic.
Why does the cargo tricycle use a differential motor?
Because it drives two rear wheels. A differential lets them turn at different speeds in corners — the same principle as a car axle — so a loaded trike tracks predictably instead of scrubbing tires. Combined with the parking brake, it is what makes three-wheel cargo duty-safe at standstill.
Why would a cargo e-bike need two batteries?
Shift length. One 48V 15Ah pack covers urban delivery; the long-tail's twin bays double capacity to 120km so a full route runs on one charge — or one bay runs while the second swaps at the depot. Battery architecture is a scheduling decision as much as an engineering one.
Can one manufacturer supply all three cargo architectures plus other categories?
Yes — that is the point of a full-range custom cargo e-bike manufacturer: three cargo layouts from one engineering source, one compliance trail, one parts list, and the same factory's city, folding and other platforms behind them.
