Eunorau | DEFENDER-S
The Defender S is a full-suspension fat-tire electric bike built for stable, comfortable rides on mixed terrain. It pairs dual 750W Bafang motors with long-range Samsung batteries and a rugged frame so you get powerful acceleration, confident handling, and the option to extend range with a second battery.
