The Flatlander SD Series is designed to revolutionize your outdoor adventures, making exploration effortless. Whether navigating open fields, following a scenic riverbend, or reaching distant landmarks, this e-bike is built for smooth travel across flat terrain and rolling hills. When your adventures follow sprawling valley floors, open prairies or winding forest roads rather than steep ridgelines, the Flatlander SD is built to go the distance. At its heart is the new RMG062A dual‑speed internal hub motor — a 750 W Bafang rear hub that delivers 85 Nm of torque and uses torque‑sensing technology for smooth, responsive power.
Bakcou has combined premium components from the Kodiak SD and Mule SD to create a rugged yet budget-friendly ride. With a 750W rear hub motor featuring 2-speed gearing and a durable 6061 aluminum alloy frame, the Flatlander SD delivers reliable power and performance while eliminating derailleur-related issues for a hassle-free experience.
For added convenience, you can integrate Bakcou’s New Geo-Nav, allowing you to lock, alarm, and monitor your bike’s health, location, and riding history in real time via your smartphone. Plus, with responsive customer support, assistance is always available—before, during, or after your ride.
Take on new adventures with confidence—the Flatlander SD is your perfect companion for exploring wide-open spaces.

Bakcou batteries are the king of e-bike batteries because they combine premium lithium-ion cells from trusted brands like Panasonic and Samsung with advanced Battery Management Systems (BMS) for optimal safety, durability, and performance.
This motor is powered by a 52 V 20 Ah integrated lithium‑ion battery, and serious distance riders can bolt on an additional 15 Ah or 20 Ah battery via the modular quick‑release rack for up to 40 Ah of total capacity—perfect for day‑long scouting trips or touring remote ranchland without range anxiety
When your adventures follow sprawling valley floors, open prairies or winding forest roads rather than steep ridgelines, the Flatlander SD is built to go the distance. At its heart is the new RMG062A dual‑speed internal hub motor — a 750 W Bafang rear hub that delivers 85 Nm of torque and uses torque‑sensing technology for smooth, responsive power.
Because the gearing is enclosed inside the hub, there’s no derailleur to hang up or break; you get a single‑speed chain ring paired with internal two‑speed gearing (40‑tooth front, 22‑tooth rear), meaning pure, silent thrust whenever you need it.
Bakcou’s engineers paired that powertrain with a rugged Air‑Craft 6061 aluminum alloy frame (lifetime warranty), a helical‑spring 100 mm front fork and a shock‑absorbing suspension seat post to soak up washboard roads and rocky two‑tracks.
The step-through design allows easy on-an-off to cater to different rider heights.
The integrated stem‑mount display with Bakcou’s On‑Demand Program (ODP) lets you customize your speed class and monitor vital stats.
The color LCD display allows for ease of use to track all your bike stats seamlessly and directly connected Bakcou’s New "Bakcou Connect" - an industry-leading technology with smartphone‑enabled GPS tracking that allows you to lock, alarm, and monitor your bike's health, location, and riding history in real-time.
