Big Easy is a long-tail electric cargo bike that expands what’s possible by bike.

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 long-tail cargo bike with passengers along for the ride. 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 – the upright, engaged rider position keeps things comfortable. 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 selected for the demands of heavy cargo hauling, including Tektro four-piston hydraulic brakes for enhanced stopping power
  • Expanded rider fit per size and long throw dropper post compatibility to improve bike sharing among different-sized riders 
  • Equipped with the most powerful Bosch electric bike motor for elevated performance
  • Features Surly dual-leg kickstand for unmatched stability when loading and unloading cargo
  • Two-seat compatibility for human passengers big or small – no adapter needed (Thule Yepp Nexxt Maxi and Burley Dash)
  • Lower stand over height for improved stability when stopping, mounting, and dismounting
  • High-rise Surly Sunrise handlebars give riders leverage to control heavy loads and the body position to keep you comfortable 
  • Featuring updated Big Dummy bags with simplified design and consistent cargo capacity
  • Damping headset for smooth and stable handling under heavy loads
  • Capable of running dual batteries for extended range
  • Large-volume 26 x 2.5" Extraterrestrial tires for smoother rides and durable wheel builds for added stiffness and strength
  • Big Easy complete bikes available for purchase in the US and Canada only
  • NOT compatible with our Bill and Ted trailers
  • Meets UL 2849, and UL 2271 certification
