A high-range electric bike
The Biwbik Etna is set up as a heavy-duty electric trekking bike: a stable platform for city riding and longer routes, with reliable mid-range components and a build focused on performance, safety, and easy maintenance.
Comfort on any terrain
The suspension package is well thought-out for a versatile bike: a Suntour fork with 80 mm of travel and a suspension seatpost. This reduces vibrations on rough asphalt and improves control both on the road and on trails.
Make the difference
Choose your double battery: 540 Wh or 900 Wh, up to 180 real-world km (depending on conditions) for long rides and intensive use.
Vinka E50N motor: 250 W and 95 Nm to climb confidently, with smooth, efficient, progressive assistance.
Anti-fatigue comfort: Suntour fork (80 mm) + suspension seatpost to ride longer with less impact.
Confidence-inspiring braking: Shimano MT200 hydraulic brakes, precise feel and control in any situation.
Ready to load and go: MIK rear rack (25 kg) and integrated rear light for commuting, panniers, and luggage.
