Riding with cargo is core to Surly's mission on this earth, whether you’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 Surly created Big Easy, their 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. It has increased stand-over height clearance and they threw in a dropper post 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.
- Full component set perfectly suited for electric cargo bikes, including four-piston Tektro brakes
- Equipped with Bosch Performance CX, their most powerful drive unit
- Capable of running dual batteries for extended range, if you’re into that. (All mounting hardware and wiring included.)
- Damping headset provides smooth and stable handling characteristics under heavy loads
- Condensed bike size range and dropper post routing to promote bike sharing and to accommodate more riders per frame size
- Includes Bosch Standard 4A charger, wiring harness, and brackets for additional battery
