A dealer asked for a fat tire folding electric bike is sometimes sent a standard 20-inch folder, or a folder with 3-inch tyres described as fat tires. This article separates those machines using the listed 20 Inch Folding Fat Tire and 20 Inch Folding Electric Bike figures, so the quotation can name tyre size, motor rating and carton width.
Short answer: A fat tire folding electric bike is a folding e-bike specified with fat tyres, which on BG EBIKE’s listed range means 20 × 4.0 tyres and an 800 W motor. The listed model has a 28 kg bare weight and a 150 × 32 × 77 cm carton (0.370 m³). The standard 20 Inch Folding Electric Bike lists 20 × 2.125 tyres, a 500 W motor, a 27 kg bare weight and a 145 × 23 × 74 cm carton (0.247 m³): only 1 kg lighter, but 9 cm narrower, and the fat-tire carton is about 50% more volume. Quote the two as separate order lines. BG EBIKE produces and assembles both models in its own factory.
What is a fat tire folding electric bike?
A fat tire folding electric bike is a folding e-bike whose tyres are specified as fat tyres, and whose order line also records that the frame folds. On BG EBIKE’s listed range, that means the 20 Inch Folding Fat Tire Electric Bike: 20 × 4.0 tyres, an 800 W brushless motor, a folding frame, front suspension fork, spoked wheels and a rear rack. Buyers also search for a fat tire folding ebike or for folding fat tire e bikes; the test is the same. A 3-inch or “plus” tyre sold as a fat tire, and a non-folding 20 × 4.0 bike such as Brown Bear, are different order lines. Wider 20 × 4.0 and 16 × 4.0 stocking questions are covered in Electric Fat Tire Bikes: What Dealers Should Stock and Specify.
How does a fat tire folding ebike differ from a standard 20-inch folder?
The two listed 20-inch folding models differ on tyre size, motor rating, battery span, catalogue speed, wheel construction and carton width. They should not be substituted for each other just because both fold and both use a 20-inch wheel label.
| Listed figure | 20 Inch Folding Fat Tire | 20 Inch Folding Electric Bike |
|---|---|---|
| Tyre size | 20 × 4.0, spoked wheels | 20 × 2.125, integrated rims |
| Motor | 800 W brushless | 500 W brushless |
| Battery | 48 V 10–20 Ah lithium | 48 V 10–25 Ah lithium |
| Catalogue top speed | 30–50 km/h | 25 km/h |
| Catalogue range | 31–60 km | 31–60 km, depending on battery |
| Bare weight | 28 kg | 27 kg |
| Package size | 150 × 32 × 77 cm | 145 × 23 × 74 cm |
| Carton volume (calculated) | 0.370 m³ | 0.247 m³ |
Figures are as listed on 13 November 2026. Speed and range are catalogue figures, not test results. Carton volumes are 1.50 × 0.32 × 0.77 = 0.3696 m³ and 1.45 × 0.23 × 0.74 = 0.2468 m³. Nominal energy is 48 V × Ah: 480–960 Wh (10–20 Ah) on the fat-tire folder and 480–1,200 Wh (10–25 Ah) on the standard folder. The fat-tire folder also lists a Shimano 7-speed gear shift, a 5-level electric control and NFC card unlocking; the standard folder’s specification table does not list a mechanical gear set or NFC. If those items matter, write them into the quotation.
Why does carton width matter more than the 1 kg weight difference?
The listed bare weights are 28 kg and 27 kg, a 1 kg gap that will not decide a container plan. The cartons will: 32 cm versus 23 cm wide, and 0.370 m³ versus 0.247 m³, so the fat-tire carton is about 50% more volume (0.3696 ÷ 0.2468). Those figures are export packing measurements, not the folded size of a ready-to-use bike. If a shop or van load depends on the folded size, record it from a sample; see the folding electric bike dimensions guide. Container planning still uses the listed carton; see the packaging and shipping page.
As a general reference, a 40HQ holds about 140 small e-bikes, 80–100 mid-size vehicles or 20–40 large vehicles. The folding fat-tire page itself refers to about 140 compact or folding e-bikes; plan the mix from the real carton widths. MOQ is flexible by model, and models can be mixed in one container. A full container is usually produced in 30–35 days once the configuration is agreed. At BG EBIKE, we produce and assemble both folding models in our own factory in Taizhou, Zhejiang, China. Supply is mainly complete bikes (CBU); SKD or CKD kits are arranged by agreement. On most models the handlebar and seat can be changed; frames stay as designed.
L01 FOLD is listed as a 500 W fat-tyre electric bike with 4.0-inch tyres, a 48 V or 60 V 20 Ah battery and a catalogue range of 60–80 km, but the live page does not list a folding mechanism, wheel diameter, bare weight or carton size. Do not use it as a substitute for the 20 × 4.0, 800 W folding fat-tire line from the public listing alone.
Is a 3-inch tyre the same as a folding fat tire?
No. On a purchase order, fat tire should be a full size such as 20 × 4.0, not a marketing word attached to a 3-inch or “plus” tyre. A 20 × 3.0 tyre, if that is what is offered, should be written as 20 × 3.0. The standard 20 Inch Folding Electric Bike lists 20 × 2.125 and should not be sold to a buyer who asked for 20 × 4.0. If the buyer only needs a compact folder and has no tyre-width requirement, say so and specify the confirmed size.
What should the quotation for folding fat tire e bikes include?
Write the quotation so that tyre size, folding function and packing width cannot be rewritten after the deposit. Include at least:
- Model, tyre size and wheel type. Name the 20 Inch Folding Fat Tire Electric Bike or the 20 Inch Folding Electric Bike, and write 20 × 4.0 (spoked) or 20 × 2.125 (integrated rims). The parts are not interchangeable.
- Motor, battery, speed and equipment. Record 800 W or 500 W, voltage, Ah and Wh, and the charger. Catalogue speed is 30–50 km/h on the fat-tire folder and 25 km/h on the standard folder. NFC and the Shimano 7-speed set are listed only on the fat-tire folder. Match the quoted version to the destination’s limits. We do not state that any model is road-legal in a given country. Neither page lists a payload; do not invent one.
- Colours, quantities and packing. Quantity per model and colour, and the carton width (32 cm versus 23 cm). If folded in-use size matters, record it from a sample. The fat-tire folder is shown in black; the standard folder lists black and white. MSDS and UN38.3 test summary supplied for lithium battery shipments.
Which costs and risks change when you switch between the two folders?
Motor rating, battery capacity, colours and quantity per model usually move the unit price; see our wholesale price page. Prices are not published on the website. Switching or mixing the two folders also changes carton volume by about 50% per unit, which changes the freight basis. Tyres and rims should not be stocked as one “20-inch folding” part. A destination that cannot accept a 30–50 km/h, 800 W catalogue version should be quoted the 500 W, 25 km/h folder only if that is the agreed configuration.

Frequently asked questions
Is a fat tire folding electric bike the same as a standard 20-inch folder?
No. On BG EBIKE’s listed range, the fat-tire folder uses 20 × 4.0 tyres and an 800 W motor, and packs in a 150 × 32 × 77 cm carton. The standard 20 Inch Folding Electric Bike uses 20 × 2.125 tyres and a 500 W motor, and packs in a 145 × 23 × 74 cm carton. Both fold and both use a 20-inch wheel label, but they are separate order lines for tyres, motors and freight.
Does a 3-inch tyre qualify as a fat tire folding ebike?
Not on a precise quotation. Fat tire should be written as a full size, such as 20 × 4.0. A 3-inch or “plus” tyre, if that is what is offered, should be written as that size, for example 20 × 3.0. BG EBIKE’s listed folding fat-tire model is 20 × 4.0, and the listed standard folder is 20 × 2.125.
Can the two folding models be mixed in one container?
Yes. MOQ is flexible by model, and models can be mixed in one container. The useful packing difference is width and volume, not the 1 kg gap in listed bare weight: 32 cm and 0.370 m³ against 23 cm and 0.247 m³. Plan the mix from those carton figures before production.
Can I use L01 FOLD as the folding fat tire e bikes specification?
Not from the public product page alone. L01 FOLD is listed as a 500 W fat-tyre electric bike with 4.0-inch tyres, a 48 V or 60 V 20 Ah battery, and a catalogue range of 60–80 km. That page does not list a folding mechanism, wheel diameter, bare weight or carton size. Confirm those fields in the quotation; do not copy the 20 × 4.0, 800 W folder’s packing figures onto it.
