5. Operating Instructions
The Gotrax Dolphin Electric Bike offers versatile riding options with its electric motor and traditional bicycle components.
5.1 Riding Modes
Your e-bike supports three distinct riding modes:
- Pure Electric Mode: Engage the throttle for motor-only propulsion. This mode allows for effortless cruising without pedaling.
- Pedal-Assist Mode: The motor provides assistance as you pedal. This mode offers 5 different speed levels, allowing you to customize the level of assistance based on terrain and desired effort.
- Normal Bike Mode: Ride the bike like a traditional bicycle, with no motor assistance.
