In-tube battery and award-winning smart design make our Sinus i-series a great transition bike for active riders who are ready for an E-Bike but prefer classic lines. You'll feel at home no matter the road surface on our WINORA Sinus iR8f thanks to its high-quality component mix. The Carbon Drive means you can enjoy the advantages of a durable, smooth running, and extremely quiet system, which is also low on maintenance.
