Cross the sea on two wheels. 70 kilometers, 6 islands, and 6 massive bridges. The full crossing of the Shimanami Kaido from **Onomichi (Hiroshima)** to **Imabari (Ehime)** is the ultimate bucket-list item for cyclists worldwide. But for most travelers, doing 70km in a single day sounds impossible—until you add the power of the **E-Bike**.
With an electric-assist bicycle, the full crossing isn’t just a physical challenge; it’s a high-speed tour of the Seto Inland Sea’s most beautiful corners.
**Quick Take**: For the full 70km crossing, I highly recommend the [Full-Day Private Support Cycle Tour](VIATOR_LINK). Having a professional guide (and a support vehicle for water and battery swaps) ensures you complete the distance comfortably and safely before the final train back.

Power Management: The E-Bike Strategy
🎯 **Can One Battery Last 70km?**
Yes, but you must be strategic. Most sports E-bikes have an “Eco Mode” that lasts up to 100km.
– **The Flat Road**: Stay in “Eco” or turn the assist off to save power.
– **The Bridge Ramps**: Switch to “Standard” or “High” to glide up the inclines.
– **The Result**: You arrive in Imabari with energy left for a celebratory dinner, rather than collapsing from exhaustion.

The Final Boss: Kurushima Kaikyo Bridge
The final bridge before Imabari is the **Kurushima Kaikyo Bridge**, the world’s first triple-suspension bridge. It is 4 kilometers of pure engineering awe. Crossing this bridge at sunset, with the whirlpools of the Kurushima Strait swirling 65 meters below you, is the emotional peak of the entire journey.
