Addmotor Graoopro Dual-Battery Cargo eBike
The Graoopro — Addmotor's dual-battery-ready utility hauler, photographed by the maker.
A 450 lb hauler with a torque sensor and a dual-battery option that claims 210 miles — at 72 lb, light for a cargo bike.
The Graoopro is the utility flagship of Addmotor's bikes: 450 lb payload, torque-sensing 750W assist, UL-certified 48V 20Ah battery — Addmotor's dual-pack configuration claims 210 PAS-1 miles — on a 72 lb mixed-wheel frame. $1,599 at Redtail — Addmotor's own price — free US shipping, warranty claims filed for you.

Why the Graoopro
A torque sensor doing cargo work
Pull away with 60 lb of groceries and the Graoopro meters power against how hard you're actually pedaling — no lurch, no lag. It's the assist system cargo duty deserves and rarely gets under $2,000.
Built for one pack — ready for two
The UL-certified 48V 20Ah pack claims 105 PAS-1 miles, and the Graoopro's EB2.0 architecture is built for a second: Addmotor publishes a dual-battery configuration claiming 210. Want the dual build? Email us before you order and we'll quote it current — the platform is already wired for it.
72 pounds, 450 rated
Most 450 lb-payload bikes weigh over 90 lb; the Graoopro's published 72 keeps it manageable in a garage and up a curb, with the 24/20 mixed wheels carrying cargo low behind you.
What stands out on the spec sheet
- Torque sensor printed on the Graoopro's own performance table
- UL 2271 on the stat strip; single/dual EB2.0 20Ah battery architecture
- 450 lb payload at a published 72 lb bike weight
- $700 verified gap to Addmotor's own list price

Who the Graoopro fits
It’s your trike if
- Serious haulers: 450 lb total payload — the highest of any two-wheeler we list from this brand
- Torque-sensor riders — assist metered against your pedal pressure, rare on cargo bikes at this price
- Long-haul planners: the dual-battery option doubles stored energy to a claimed 210 PAS-1 miles
- Mixed-wheel handling: 24-inch front, 20-inch rear keeps the load low and the steering normal
Riding a different ride? We stock it
- You're under 5'9" and want the lower step-over — the Garootan M-81 is the compact cargo pick at $1,199.
- The cargo is a passenger on three wheels — the Greattan L carries a rated bench on a trike platform.
- You'd rather fold than haul — the Foldtan M-160 is the same money in a 34-inch fold.
Straight answers before you order
Mechanical disc brakes, where the cheaper M-81 runs hydraulic.
Addmotor spent the Graoopro's budget on the torque sensor and dual-battery architecture instead; cables are driveway-serviceable, and if hydraulic braking outranks those for you, the M-81 is $400 less. See the Garootan M-81.
No owner reviews on Addmotor's store at our pull date.
It's the newest utility platform in their range, built from the same 750W motor family and EB2.0 battery system as the reviewed bikes here, under the same 2-year warranty — with Redtail filing any claim for you.
Addmotor's own table prints the fork's description in the Frame row too — a copy error on their page.
We quote their sheet and flag the slip rather than silently fix it: the fork is an 80mm oil-spring unit, and the frame is the aluminum utility layout in the photos. Everything else on the row set checks out.
Addmotor prohibits NYC delivery, including billing addresses, under Local Law 39.
Everywhere else in the lower 48 ships free; on the NYC line, ask us first and we'll confirm current status.
What you get with the order
Shipping
Free shipping on every electric bike within the contiguous United States (lower 48).
Orders are prepared and dispatched within 1–3 business days. Most e-bikes arrive within 5–10 business days after dispatch, depending on location.
Ships via trusted parcel and freight carriers — UPS, FedEx, and LTL freight for larger items — with tracking emailed at dispatch. Trikes ship large; an adult signature is required at delivery.
Delivery protection
Inspect your shipment at delivery. Damage, defects, or incorrect items must be reported with photos within 48 hours; claims submitted after this window are not accepted.
Trikes with power, charging, or component issues are covered under the manufacturer warranty; Redtail coordinates repair or replacement remotely at no cost to the customer.
Returns
Addmotor's own return policy applies when you buy direct: 14 days, under 10 miles on the odometer, and a condition-based 10–30% restocking fee they set after inspection. Buy here and Redtail's terms apply instead — unopened orders within 3 days of delivery at a flat 15% restocking fee, a number you know before you pay, never a grade handed down after. Full terms: Redtail Refund & Return Policy.
Alaska, Hawaii, U.S. territories, P.O. boxes, and remote areas may incur extra charges or be excluded — contact us before ordering. Addmotor has suspended e-bike and e-trike shipments to New York City (all five boroughs) under its current shipping policy, so we cannot deliver this model to NYC addresses right now — email us and we'll confirm status before you order. Full terms: Redtail Shipping Policy · Redtail Refund & Return Policy. Addmotor publishes its own shipping and return terms, which apply to orders placed directly with Addmotor, not to orders placed here.
Owning it in your state
Built for commutes, errands and paved-path miles: fully operable pedals, assistance capped at 20 mph, and a 750-watt rated motor — right at the figures the federal low-speed electric bicycle definition (15 U.S.C. § 2085: 'less than 750 watts', less than 20 mph on motor power alone) is written around. Your state writes the street and path rules. The details for your state are in our state-by-state e-bike law guide.

Specifications as published by Addmotor at www.addmotor.com/products/graoopro, archived 2026-08-29. Figures are the manufacturer's ratings, not our test results. Metric-to-US conversions are ours and marked in parentheses.
How to read this spec sheet
Where Addmotor's own page prints more than one figure for the same spec, the table above carries the one we could verify twice, and this list names every such case and the figure we chose:
- Addmotor's Frame row repeats the fork description ('Oil Spring Fork with 80mm of Travel') — their copy error, quoted and flagged rather than silently corrected.
- The 210-mile headline is the dual-battery PAS-1 estimate; the single-pack claim is 105+ miles, and both are estimates under Addmotor's own policy.
- No rider-height window is published for the Graoopro; we print the sizing that exists and invent nothing.
What we counted
We swept Addmotor US's own storefront on 2026-08-29 and counted its two-wheel e-bikes: 8 distinct models, 5 merchandised on its electric-bikes collection page and 3 more (Citypro E-43, Foldtan M-140, Kunlun) live as product pages but absent from that collection page at our sweep. We list all 8, price-matched to their pages the same day.

Warranty — and who deals with the factory (not you)
| Component | Coverage |
|---|---|
| Frame | 2 years for the original owner |
| Battery (20Ah packs) | 2 years (13.5Ah and 15Ah packs: 18 months); Addmotor rates its batteries at roughly 800 charge cycles |
| Motor | 2 years (for motors purchased on or after March 1, 2024; 1 year before that date) |
| Parts & components | 1 year — forks, stem, handlebar, headset, seat post, lights, bottom bracket, rims, wheel hub, derailleur, throttle, wiring harness, controller, display and kickstand |
What it covers
Defects in materials and craftsmanship for the original owner, on the components above, for bikes bought new. Warranty terms are locked to the policy in force at purchase.
What you must do
- Proof of purchase from Redtail (your order confirmation is enough)
- Dated photo or video evidence of the fault — Addmotor processes no claim without it
- Inspect on delivery: note visible damage on the delivery paperwork before signing, photograph the box and the part, and report it to us immediately — shipping-damage windows are short and carrier-dependent
Not covered
- Normal wear and tear — tires, tubes, brake pads, rotors, bearings and similar consumables
- Theft, vandalism, or loss
- Damage from ignoring the manual, improper assembly, or incorrect adjustment
- Unauthorized third-party service or parts (unless approved by Addmotor in advance, with a quote)
- Battery damage from power surges, improper or unauthorized chargers, or poor storage
- Abuse, neglect, modification, accidents, or use beyond intended purpose
- Shipping damage not documented promptly with dated photos (and noted on the Bill of Lading for freight)
Addmotor Limited Warranty issued by Addmotor Tech Inc., as published on its warranty policy page. Start a claim by replying to your Redtail order confirmation with photos or video and your order number — we file the claim with Addmotor and manage it on your behalf; Addmotor ships approved replacement parts within 1–10 business days of an accepted claim.
Frequently asked questions
How fast does the Graoopro go?
20 mph assisted, printed in Addmotor's own technical table — the same ceiling as the rest of the range.
Is Addmotor a good brand for a cargo e-bike?
The Graoopro pairs a torque sensor and UL 2271 battery print with a 450 lb rating — a spec sheet that competes two price tiers up. Buying at Redtail adds free US shipping and a warranty we file and track for you.
How does the dual-battery option work, and how long do they take to charge?
The Graoopro's EB2.0 system supports a second 48V 20Ah pack, and Addmotor claims 210 PAS-1 miles for the pair against 105 on one. Our listing ships the single-pack build; if you want the dual configuration, email us before ordering and we'll quote it current. Addmotor quotes 8–10 hours per pack for a full charge.
Where are Addmotor bikes made?
