Simplify the Haul With an Electric Cargo Bike

Riding loaded with cargo is core to us here at Surly, whether we’re running a front rack and bag setup or a full-blown cargo bike and trailer. There are times, however, when even the strongest riders are limited in what they can haul, so we created Big Easy, our long-tail electric cargo bike. Consider it the 18-wheeler of the cargo bike world, minus the diesel fumes.

When it comes to geometry, Big Easy rides and feels like a normal-length bike. We also increased stand-over height clearance and threw in dropper post routing to promote bike sharing across different-sized riders. So whether you want to wave goodbye to the old family gas hog, upgrade your bike-supported business’s two-wheeled fleet, or simply haul more bowling balls during your daily commute, Big Easy makes doing all that, well, easy.
