Riding Modes
The SAMEBIKE SY26-II offers three distinct riding modes:
- Pure Electric Mode: Turn on to accelerate using only the lithium battery. Provides strong and sustained power. Range: 25-35km.
- PAS (Pedal-Assisted System) Mode: The motor provides assistance as you pedal. This mode is electricity-saving and energy-saving. Range: 40-80km.
- Manpower Riding Mode: Pure manpower riding, similar to a traditional bicycle. Turn on for fitness.
Switch between modes using the controls on the handlebar (refer to Figure 3).
Braking System
The e-bike is equipped with front and rear stable double disc brakes for sensitive and safe stopping power.
The brake levers are located on the handlebar. Squeeze both levers simultaneously for effective and controlled braking. The system includes a power-off priority feature, which cuts motor power when brakes are applied.
Gear Shifting
The e-bike features a sensitive variable speed system with a rear 7-piece spinning flywheel and Shimano components for smooth and effortless gear changes.
Use the Shimano shifter on the handlebar to change gears according to terrain and desired speed. Ensure smooth transitions to prevent chain damage.
Intelligent Electric & Assisted Power System
The specially adjusted power-assisted induction system ensures a smoother cycling experience.
This system integrates various components like the road sensor, battery management system, and assisted sensor to optimize power delivery from the brushless motor based on your pedaling input.
Headlight and Suspension
The high-power LED headlight ensures safety during night rides. The front fork suspension system effectively reduces disruption from various road conditions, providing a comfortable riding experience.
