A dealer searching for electric fat tire bikes is often looking at several machines under one label: a 26 × 4 all-terrain bike, a compact 20 × 4.0 or 16 × 4.0 e-bike, or a folding 20 × 4.0 model. This guide uses BG EBIKE’s listed figures to show what the quotation must name: the full tyre size, the model, the wheel type, and the carton used for container planning.
Short answer: Electric fat tire bikes should be specified by a tyre size such as 20 × 4.0 or 16 × 4.0, plus the model and wheel type. Search results also mix in 26 × 4 all-terrain mountain bikes, which BG EBIKE does not list. Brown Bear is a listed 20 × 4.0, 1000 W bike at 35 kg with a 130 × 32 × 70 cm carton (0.291 m³); Jaguar shares that motor, weight and carton, with 16 × 4.0 tyres on spoked wheels. The folding 20 × 4.0 model lists 800 W and a 150 × 32 × 77 cm carton. BG EBIKE produces and assembles these models in its own factory, with flexible MOQ by model and mixed containers.
What tyre size should a dealer write when ordering electric fat tire bikes?
Write the full tyre size, for example 20 × 4.0 or 16 × 4.0, plus the model and wheel type. A line that only says fat tire, or only says a 20 fat tire electric bike, leaves the factory to guess the diameter, the rim, and sometimes whether the bike folds.
How tyre markings are read, including width and diameter, is set out in our e-bike tire size guide. The consumer question of why wide tyres are used on e-bikes is covered separately in Why do electric bikes have fat tires?; the buying decision here is how to specify the size on a purchase order.
| What appears in the search | Tyre size to write | BG EBIKE listed example | What a dealer should not assume |
|---|---|---|---|
| 26 × 4 all-terrain or mountain fat-tire e-bike | 26 × 4.0, if that is the required type | Not listed. The listed 26-inch electric mountain bike uses 26 × 2.125, not 26 × 4.0 | That any 26-inch e-bike is a fat-tire mountain bike |
| Compact 20 × 4.0 e-bike, including moped-style frames | 20 × 4.0, with the model and wheel type | Brown Bear (integrated wheels). Warthog, S1, U8, RX and RXS also list 20 × 4.0 | That all 20 × 4.0 models share one carton or wheel set |
| 16 inch fat tire ebike | 16 × 4.0, with the model and wheel type | Jaguar, 16 × 4.0 on spoked wheels | That a 4.0-inch width is interchangeable with a 20 × 4.0 wheel |
| Folding 20 × 4.0 e-bike | 20 × 4.0, and that the frame folds | 20 Inch Folding Fat Tire Electric Bike | That a standard 20 × 2.125 folder, or a non-folding 20 × 4.0 bike, is the same order line |
| Fat-tyre e-bike listed only as 4.0-inch width | The diameter as well as the 4.0-inch width, once confirmed | L01 JET and L01 FOLD list 4.0-inch tyres and 500 W; diameter, weight and carton are not listed | That a 4.0-inch width is already a 20 × 4.0 packing line |
| Seated scooter or kick scooter with a wide tyre | The scooter tyre size, not an e-bike size | K7 lists 225/40-10. L2 is a kick scooter with mixed 26 × 4.0 / 20 × 4.0 wheels | That a wide scooter tyre can be quoted as an electric bicycle with fat tires |
Z3 and V1 also list 20 × 4.0 tyres; seat layout is covered in the two-seater electric bike guide and is not repeated here. Moped-style frames that use the same size are introduced in the moped-style e-bike guide for dealers.
How do a 20 fat tire electric bike and a 16 inch fat tire ebike compare on listed figures?
On the listed 1000 W platform, Brown Bear and Jaguar are not separated by motor power, battery range, bare weight or carton size. The useful comparison is tyre diameter and wheel type. The folding 20 × 4.0 model sits on a different electrical and packing line.
| Listed figure | Brown Bear | Jaguar | 20 Inch Folding Fat Tire |
|---|---|---|---|
| Tyre size | 20 × 4.0, integrated wheels | 16 × 4.0, spoked wheels | 20 × 4.0, spoked wheels |
| Motor | 1000 W brushless | 1000 W brushless | 800 W brushless |
| Battery | 48 V 10–21 Ah lithium | 48 V 10–21 Ah lithium | 48 V 10–20 Ah lithium |
| Nominal energy (calculated) | 480–1,008 Wh | 480–1,008 Wh | 480–960 Wh |
| Catalogue top speed | 30–50 km/h | 30–50 km/h | 30–50 km/h |
| Catalogue range | 60 km | 60 km | 31–60 km |
| Bare weight | 35 kg | 35 kg | 28 kg |
| Package size | 130 × 32 × 70 cm | 130 × 32 × 70 cm | 150 × 32 × 77 cm |
| Carton volume (calculated) | 0.291 m³ | 0.291 m³ | 0.370 m³ |
| Frame type | Non-folding, 20-inch fat-tyre e-bike | Non-folding, 16-inch fat-tyre e-bike | Folding, 20-inch fat-tyre e-bike |
Figures are as listed on each product page for the standard configuration on 13 November 2026. Speed, range and charging time (5–8 hours on Brown Bear and Jaguar; 4–6 hours on the folding model) are catalogue figures, not test results. Carton volumes are calculated from the listed centimetre dimensions: 1.30 × 0.32 × 0.70 = 0.2912 m³, and 1.50 × 0.32 × 0.77 = 0.3696 m³. Nominal energy is voltage multiplied by capacity (48 V × 10 Ah = 480 Wh; 48 V × 21 Ah = 1,008 Wh; 48 V × 20 Ah = 960 Wh).
Jaguar’s 16 × 4.0 tyres on spoked wheels and Brown Bear’s 20 × 4.0 tyres on integrated wheels are not interchangeable spare parts, even though both are 4.0 inches wide and both list a 1000 W motor and a 48 V 10–21 Ah lithium range. Keep the full tyre size, wheel type and model reference on the spare-parts order. The two non-folding models also share one listed bare weight (35 kg) and one carton, so packing volume is not a reason to treat them as the same vehicle. The folding 20 × 4.0 model is a different order line: 800 W, a 28 kg bare weight, and a carton that is 20 cm longer and 7 cm taller, or about 0.078 m³ more volume per unit.
L01 JET and L01 FOLD are also listed as fat-tyre electric bikes: 500 W, a 48 V or 60 V 20 Ah battery (960 Wh or 1,200 Wh at the listed values), front and rear disc brakes, and catalogue ranges of 80–100 km and 60–80 km. Those pages list a 4.0-inch tyre width but do not list wheel diameter, bare weight or carton size, so they cannot be planned as a 20 × 4.0 packing line from the public listing alone.
How do carton sizes change a container plan for electric fat tire bikes?
A shared 20 × 4.0 tyre size does not mean a shared carton. Plan the container from the listed package size and bare weight of each model, then confirm the loading plan from the packing version that will actually ship.
| Model | Listed tyres | Listed package size | Carton volume (calculated) | Bare weight, not shipping gross |
|---|---|---|---|---|
| Brown Bear / Jaguar | 20 × 4.0 / 16 × 4.0 | 130 × 32 × 70 cm | 0.291 m³ | 35 kg |
| 20 Inch Folding Fat Tire | 20 × 4.0 | 150 × 32 × 77 cm | 0.370 m³ | 28 kg |
| S1 | 20 × 4.0 | 165 × 26 × 87 cm | 0.373 m³ | 36 kg |
| Warthog | 20 × 4.0 | 170 × 29 × 94 cm | 0.463 m³ | 39 kg |
Warthog’s carton is about 59% more volume than Brown Bear’s (0.4634 ÷ 0.2912), even though both list 20 × 4.0 tyres. U8 lists 145 × 30 × 80 cm (0.348 m³, 36 kg); RX and RXS list 150 × 30 × 83 cm (0.374 m³) at 50 kg, 15 kg heavier than Brown Bear. How folding 20 × 4.0 packing compares with a standard 20 × 2.125 folder is covered in Fat Tire Folding Electric Bike: How It Differs from a Standard Folder.
As a general reference, a 40HQ holds about 140 small e-bikes, 80–100 mid-size vehicles or 20–40 large vehicles. The listed pages use that kind of guide by vehicle size: the folding fat-tire page refers to about 140 compact or folding e-bikes, and Warthog’s page refers to about 80–100 full-size e-bikes. The exact mix is planned from the real carton sizes before production. See the packaging and shipping page.
At BG EBIKE, we produce and assemble these models in our own factory in Taizhou, Zhejiang, China. Motorcycle parts work began in 2016 and complete vehicles in 2018, with output of about 10,000 units a year. MOQ is flexible by model, because vehicle size decides how many units fill a container; models can be mixed in one container. A full container is usually produced in 30–35 days once the configuration is agreed. Supply is mainly complete bikes (CBU); SKD or CKD kits are arranged by agreement.
What should a dealer ask a supplier before quoting electric fat tire bikes?
Ask for a specification that two suppliers would describe in the same way, and that a spare-parts desk can follow later. Include at least:
- Model, tyre size, wheel and frame type. Name Brown Bear, Jaguar, the folding 20 × 4.0 model, or the agreed alternative, and write 20 × 4.0 or 16 × 4.0. Record whether wheels are integrated or spoked, and whether the frame folds. Do not stop at “fat tire.”
- Motor, battery and speed. Record rated power, voltage, Ah and Wh, and the charger. On Brown Bear and Jaguar, 48 V × 10 Ah is 480 Wh and 48 V × 21 Ah is 1,008 Wh. Several models list catalogue speeds of 30–50 km/h and motors of 800 W or 1000 W, which may sit above some e-bike thresholds; match the quoted version to the market before production. We do not state that any model is road-legal in a given country.
- Equipment and payload. Use listed values where they exist. Brown Bear’s page does not list a brake type; if brakes matter, write them into the quotation rather than inferring them from a photograph or from Jaguar. These pages also do not list a payload figure. Do not invent one. If a load limit is agreed, write it; if none is listed, say so on the quote.
- Colours, packing and documents. Quantity per model and colour, carton size, and any logo requirement. On most models the handlebar and seat can be changed; frames stay as designed. Parts are sold separately. MSDS and UN38.3 test summary supplied for lithium battery shipments.
Which costs and risks change when the tyre size or carton changes?
Unit price usually moves with motor rating, battery capacity, colours and quantity per model; see our wholesale price page. Prices are not published on the website. Packing volume still changes how many units fit: swapping a Brown Bear line for a Warthog line, or adding folding 20 × 4.0 units beside compact 20 × 4.0 units, changes the loading plan even if the tyre width looks the same in a photo. Freight quotations should use the actual carton mix. Spare parts should be ordered by full tyre size, wheel type and model, because 16 × 4.0 and 20 × 4.0 assemblies, or integrated and spoked rims, are not one stock item. A destination limit below a listed 800 W or 1000 W, 30–50 km/h catalogue figure should be fixed in the quotation before production.

Frequently asked questions
Are electric fat tire bikes the same as 26-inch all-terrain mountain bikes?
No. Many search results for a fat tire ebike show 26 × 4 all-terrain mountain bikes. BG EBIKE does not list that style in this e-bike range. The listed 26-inch electric mountain bike uses 26 × 2.125 tyres, not 26 × 4.0. The fat-tyre e-bikes here are specified as 20 × 4.0 or 16 × 4.0, or, on L01 JET and L01 FOLD, as a 4.0-inch width without a listed diameter. Write the size you need on the quotation.
Does a 16 inch fat tire ebike pack differently from Brown Bear?
Not on the listed figures. Jaguar and Brown Bear both list a 35 kg bare weight and a 130 × 32 × 70 cm carton, which is 0.291 m³. The difference to record is the wheel: 16 × 4.0 on spoked wheels versus 20 × 4.0 on integrated wheels. Those assemblies are not interchangeable, so keep separate order and spare-parts lines even though they share a packing volume.
Can 16-inch and 20-inch electric fat tire bicycles be mixed in one container?
Yes. MOQ is flexible by model, and models can be mixed in one container. Jaguar and Brown Bear cartons are the same listed size, but other 20 × 4.0 models are not: Warthog is 0.463 m³, and the folding 20 × 4.0 carton is 0.370 m³. Plan the mix by carton volume and bare weight, and confirm the packing version before production.
Is a 4.0-inch tyre enough to quote an e bike fat tire?
No. A 4.0-inch width still needs a diameter, a model name and a wheel type. L01 JET and L01 FOLD list 4.0-inch tyres and a 500 W system, but not wheel diameter, bare weight or carton size. A seated scooter such as K7 uses 225/40-10 tyres, another size again. Ask for the full marking; do not treat a width-only listing as a 20 × 4.0 packing line.
