Cargo Ebikes for Delivery Fleets: Payload, Range and Uptime

A delivery ebike is not a consumer product with a box on it; it is a vehicle that must earn money daily, and its specification should be written like one. This catalogue carries two genuine cargo builds with different philosophies — the longtail C18 and the heavy-rated fat B17-C — and they make a useful framework for speccing a fleet.

Start with payload honesty

Payload ratings decide what work the bike can legally and durably do. The C18, the longtail cargo bike with a 26-inch front and 20-inch rear wheel, is rated at 120 kg with an extended rear rack. The B17-C, the fat-tire cargo variant, is rated at 200 kg — the highest figure in this catalogue — with rack and meal-box options aimed at food delivery. Neither number is a suggestion: running a fleet chronically at or beyond rating eats frames, wheels and brakes. Spec the rating with the rider, the typical load and a margin, exactly as you would a van.

Range is a shift-planning number

The C18 carries a 48V 15Ah pack — 720 watt-hours, the largest energy fitted to a cargo model here — and publishes a 31–60 km band. The B17-C publishes the same 31–60 km band from its LG 48V 15Ah pack, and the B17 runs a larger Samsung-cell 48V 17.5Ah pack. Both figures underline the fleet rule: plan routes at the low end, and solve range with logistics, not hope — swappable packs, a mid-shift top-up, or route lengths matched to one charge. Cargo consumption is roughly double a solo commuter's per kilometre; any fleet model that ignores this will strand riders in month one.

Drive and brakes for loaded work

The three cargo builds split the drive question by duty. The B17 uses a 1000W Bafang Ultra mid-drive — loaded starts on grades are the mid-drive's home ground, with torque multiplied through the gears. The B17-C uses a 500W Bafang G020 rear hub and the C18 a 250W rear hub: simpler drives for stop-start urban duty on flatter routes, where wheel-level service keeps a fleet moving. Braking deserves equal attention — a loaded cargo bike at city speed carries serious kinetic energy; the C18's published brakes are Tektro mechanical discs with motor cut-off levers, and any fleet specification should confirm the brake class against its heaviest loaded descent. Add a fleet-level habit: pads and chains on a fixed inspection rhythm, because a cargo bike's consumables live a commercial, not recreational, life.

Uptime is a system, not a spec

The bike is half the system. The other half: spare packs (one per bike minimum in intensive use), a small shelf of consumables and crash parts from the supplier's parts line agreed with the first order, riders trained on the drive systems they use (on mid-drive units, the battery and chain savings from good shifting are real), and a swap-bike or rapid-repair arrangement so a down bike never means a down route. Because the two fat cargo builds sit inside the wider fat-tire family, much of the consumables shelf — tires, tubes, brake pads, chains — is shared with the leisure models, which simplifies the stores a fleet has to keep.

Weather and seasons: the fleet's second specification

A delivery fleet specified in May meets its real examination in January. Cold cuts battery output exactly when delivery demand peaks, rain doubles the value of mudguards, sealed connectors and rider kit, and darkness moves lighting and reflective equipment from the accessories list to the safety case. The cargo builds here answer parts of this directly — fat tires that keep working on wet leaves and slush, packs sized with headroom — but the seasonal plan is the operator's: rotate the freshest packs to the longest winter routes, shorten routes rather than stretching charge discipline, and schedule the deep service (brakes, bearings, drivetrain) before the season that punishes neglect. Fleets should also plan the commercial shape of winter: if drops per shift fall, the cost-per-drop model from the next section must be re-run on winter figures before anyone concludes the ebikes stopped working. Usually the model shows the territory shrunk, not the vehicle — and a smaller winter territory profitably served beats an abandoned fleet and a spring restart.

Cost per drop: a simple model

Fleet decisions improve when the comparison unit is cost per completed drop, not cost per vehicle. Build the model with your own numbers in five lines: vehicle cost spread over its working life; energy per shift (a cargo pack charged daily is a small, knowable figure); consumables per thousand kilometres (chains, pads, tires — commercial-duty items, priced from the parts shelf you agreed at purchase); labour for the inspection rhythm; and downtime cost, which is where the uptime system above earns its budget. Against a van on dense urban routes, the ebike column usually wins on energy, parking and time-at-stop, and loses on drops per shift where routes are long or loads are heavy — which is why the honest fleets pilot on their densest routes first and let the model, not enthusiasm, pick the territory. Re-run the model after the pilot with measured figures; a supplier conversation grounded in your cost-per-drop data produces a better specification than any catalogue debate.

Riders are part of the specification

The best-specced fleet fails with riders who hate the bikes. Involve two or three working riders in the sample stage: their verdict on riding position, load handling and the fold or stand they use fifty times a day is operational data. Train the habits that protect the machines — shifting under load on mid-drives, load securing on the deck, charge discipline at shift end — and write them into the same one-page sheet as the inspection rhythm. Fleets that do this see it in the consumables column within a quarter.

The business case, honestly

Cargo ebikes win where vans lose: dense urban cores, parking scarcity, short-drop density and low running cost per stop. They lose where distance, weather exposure or payload mass dominate. Fleets that pilot with a handful of units on their densest routes, measure cost per drop against the van baseline for a season, and then scale, are the ones still running ebikes in year three. Start with the pilot conversation — samples of the cargo builds, your route data, and a spares shelf in the same quotation.
