Strike the perfect accord between efficiency and comfort with Haibike's SDURO FullNine SL. Well-selected components, a central seating position, and Haibike's SES suspension system make this bike ideal for touring off-roaders. The Yamaha motor system perfectly marries smooth function with fun, unbridled power. It uses three sensors (torque sensor, speed sensor, and crank sensor) to create a wholly organic feeling of assist. It’s so smooth you might forget you're pedaling uphill. The Li-Ion 400Wh battery is compact, tidy, and charges easily on or off the bike. It also easily locks onto the frame for added peace of mind when you’ve got to step away.
Yamaha's mid-drive motor system's overall theme is "smooth and powerful". It uses a torque sensor that detects pedaling power, a speed sensor that detects the bicycle's speed, and a crank sensor that detects the number of rotations through pedaling to create an organic feeling of assist.
-Lightweight, compact 400Wh battery that can be charged on the bike, and be locked to the frame
-Zero Cadence Support ensures the system will engage at the first pedal stroke with lively, powerful assist
-Four power modes (OFF, ECO, STD, HIGH) let you choose the level of assist that you're feeling at the moment
-Navigate through a ton of metrics on the bright, easy to read display with the handy control unit
The center of rotation on a full suspension bike is typically located behind the chainring (A). This creates a smooth wheel path, minimizes pedal kickback, and stabilizes the chain. This same design creates problems when used with a motor (B); it creates a wheel path that increases pedal kickback and lengthens the wheelbase significantly, causing the bike to stiffen up against obstacles and handle poorly.
Haibike's engineers created the SES (Sprocket Equalizing System)(C), which separates the chain from the chainring by guiding the chain over a pulley wheel that is located directly on the swingarm pivot point. This decreases pedal kickback while preserving a short, sporty wheelbase and quick handling.
