FLATLANDER SD

The Flatlander SD uses an internal dual‑speed Bafang hub motor (model RMG062A) rated at 750 W nominal and 85 Nm of torque. Unlike mid‑drive bikes with external derailleurs, this hub motor houses two internal gears, so you don’t have to shift manually and there’s no derailleur to break. A built‑in torque sensor provides smooth, responsive pedal assist.

While not possible to give a precise single‑charge range for any bike because your mileage will depend on factors like terrain, elevation, rider weight, wind, temperature and the level of assist or throttle you use, we can offer a ballpark estimate: with a single battery most riders see around 40–60 miles of real‑world range, and with a dual‑battery setup you can extend that to over 100 miles. Think of these numbers as general guidance rather than guarantees because actual range will always vary based on how and where you ride.

The Flatlander SD is optimized for flatlands and rolling hills, hence the name. Its dual‑speed hub motor provides plenty of torque for moderate inclines, but it isn’t meant for the extreme climbs that our mid-drive bikes can tackle.

Bakcou Connect is optional on the Flatlander SD. For an additional fee, you can add this connectivity package, which lets you track your bike’s location, lock it remotely and monitor battery health via smartphone. The first year of service is free; a subscription fee applies afterward. This feature must be added at checkout.

The included 52 V/4 A smart charger will recharge the 20 Ah battery in about 4–5 hours from empty. Charging times may be slightly longer if you add a second battery.

For all of our ebikes, we stand behind your purchase with a one‑year limited manufacturer’s warranty. The warranty starts the day you receive your bike and covers major components like the battery, frame, motor, controller, wiring harness and LCD display. To activate your coverage, be sure to register your bike within 30 days of delivery; the warranty is valid only for the original owner and can’t be transferred. It protects you against manufacturing defects in materials and workmanship but doesn’t cover normal wear, misuse or modifications. If you ever have a problem, just reach out to our support team and we’ll guide you through the warranty claim process.
