1000W Mid-Drive Fat Tire Ebikes
Four fat tire models built on 1000W Bafang crank drives — the M620 in the E18-A and B11, the Ultra in the B17 and the BBS-HD in the B13 — for buyers whose riders climb, haul or ride soft ground fully loaded.
A 1000W mid-drive changes what a fat tire bike can do. Because the motor drives through the chain and gears, torque stays available at climbing speeds where a hub motor fades, and the bike keeps pulling on snow, sand and fire roads with a loaded rack. These four models are the top of the fat tire family, and each takes a different position: the E18-A is the full-suspension carbon flagship, the B11 is its alloy counterpart, the B17 is the cargo-leaning build with the family's biggest battery, and the B13 is the air-forked mountain-fat hybrid.
The Four Models
| Model | Motor | Battery | Range (PAS) | Max Speed | Payload |
|---|---|---|---|---|---|
| E18-A | Bafang M620 mid-drive, 1000W | LG 48V 15Ah | 40–65 km | 42–48 km/h | 120 kg |
| B17 | Bafang Ultra mid-drive, 1000W | Samsung-cell 48V 17.5Ah | 31–60 km | 50 km/h | 120 kg |
| B11 | Bafang M620 mid-drive, 1000W | LG 48V 15Ah | 31–60 km | 45 km/h | 150 kg |
| B13 | Bafang BBS-HD mid-drive, 1000W | LG 48V 15Ah | 10–30 km | 25 km/h | 150 kg |
E18-A — full-suspension carbon flagship
The E18-A pairs the Bafang G510 M620 (48V, 1000W; the manufacturer cites peak torque of 200 N.m) with an LG 48V 15Ah battery in a carbon fiber frame. Running gear is a step above the rest of the family: DNM suspension front and rear, CST 26×4.8 tires, Magura MT4E hydraulic brakes with 203mm rotors, a SRAM NX 11-speed drivetrain and an EXA dropper post. Published range is 40–65 km on pedal assist, with torque and speed dual sensing and a thumb throttle.
B11 — the alloy M620 build
The B11 uses the same M620 mid-drive and an LG 48V 15Ah battery in a 6061 alloy frame, with an RST Guide fork, CST 26×4.8 tires, Tektro hydraulic brakes and a Shimano Alivio 9-speed drivetrain. It is the practical way to buy the M620 platform without the carbon frame, and it is rated to a 150 kg payload.
B17 — 1000W cargo build
The B17 runs a Bafang Ultra 1000W mid-drive with the family's largest battery, a Samsung-cell 48V 17.5Ah pack. The chassis is set up for work: Kenda 24×4.0 front and 20×4.0 rear tires, a front basket and a rear rack. Its specification-table range is 31–60 km; use that figure, not the higher number in the model's marketing text.
B13 — air-fork fat mountain build
The B13 combines a Bafang BBS-HD 1000W mid-drive with a GT 860 air fork, MAXXIS 26×4.8 tires and an Alivio 9-speed drivetrain. Note its published range band of 10–30 km — the shortest in this group — and its 25 km/h published top speed; if your program needs longer range, the E18-A or B17 is the better starting point.
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.
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.
Are 1000W models road-legal everywhere?
No. Power and speed limits differ by market and many markets cap assistance well below 1000W. These models are typically sold for off-road, private-land or specifically permitted use; confirm the regulations in your market and tell us the configuration you need.
What certificates do the products carry?
Certificates available upon request. Send your target market in the inquiry and we will confirm which documentation can be provided for the models you are sourcing.
