Fat Tire Electric Bikes: 25 Models from 250W to 1000W
The largest family in the catalogue. Fat tire platforms in 20-inch and 26-inch formats, with rear-hub, integrated-wheel and Bafang mid-drive systems, payloads from 100 kg to a cargo-rated 200 kg.
Fat tire bikes are where this factory's range is deepest, and the family splits into clear sub-groups. At the top sit the mid-drive flagships: the full-suspension carbon fiber E18-A on a Bafang M620, the B11 and B13 on 1000W crank drives, and the B15, B19 and B8 M on 750W BBS02 mid-drives. The volume middle is rear-hub: 500W and 750W models on 20-inch and 26-inch wheels, with LG or domestic-cell batteries. At the utility end are the folders (B1, B5, B3-A) and the cargo builds (B17, B17-C).
Wheel diameters span 20, 26 and 27.5 inches (the B17 cargo build mixes a 24-inch front with a 20-inch rear), and tire widths run from the B25's 2.35 inches to 4.8 inches. The widest tires (4.8in on the E18-A and B11) are the snow and sand specialists; 4.0in is the all-round format; the 20×3.0 B24 trades some float for city maneuverability. Almost every model publishes a 31–60 km pedal-assist range; the exceptions are stated in the table (the B13 and B25 publish shorter bands, the E18-A a longer 40–65 km).

Specification notes: values are the manufacturer's published specification-table figures for each model. The B17's specification-table range is 31–60 km (a higher figure appears in that model's marketing copy; the table value is the one used here). Payload is the manufacturer's rated maximum load.
Choosing Inside the Family
For snow, sand and hunting: start with the 26×4.8 mid-drive models (E18-A, B11) or the 26×4.0 hub models (B8, B10) and read the snow ebike and hunting ebike pages. For delivery and cargo: the B17-C is rated to 200 kg and the B17 pairs a 1000W mid-drive with a 17.5Ah battery; see electric cargo bikes. For compact storage: B1, B5 and B3-A fold, and B20/B25 add folding stems. For value volume: the 500W rear-hub 20-inch models (B3, B4, B5, B23) sit closely together in specification. Before ordering spares for a fleet, confirm component part numbers and interchangeability for each model.
Questions Buyers Ask
Can I order samples first?
Yes — under the factory's published sample policy, spare units can be provided for sampling; the sample fee and courier cost are paid by the buyer. Confirm availability for the models you want when you inquire.
Which fat tire models use LG or Samsung cells?
Per the published data: LG cells in the E18-A, B24, B13, B14, B15, B10, B19, B25, B11, B8-U, B8 M and B17-C; Samsung cells in the B17 (17.5Ah) and B3-A (14.5Ah). The remaining models do not publish a cell brand in their model data. Confirm the cell specification for your order in the quotation.
How long does production take?
The published lead time is 30–60 days after the advance payment is received, depending on the product category and order quantity. Ask us to confirm the schedule for the exact models in your inquiry.
