This article is meant to be an initial overview on the Surly Big Easy cargo bike. If you are looking for my review, that is over here.
Surly has had a few iterations of longtail cargo bikes over the years. The Big Dummy, and the Big Fat Dummy. Both of these bikes have fit a need for heavy-duty hauling that is somewhat compatible with Xtracycle parts. This morning Surly dropped a new bike, an electric bike.
Meet the Surly Big Easy Electric Longtail Cargo Bike
A Bosch Performance CX equipped, Class-1, steel, 26″ wheeled, longtail cargo bike. That’s a mouthful.
What makes this bike special? It’s equipped for daily kid hauling, or easily hook up the Surly trailer system to haul even more gear. 26″ wheels are more forgiving and have a wide selection of tires. I picture this being the kid/grocery hauler during the week and the bikepacking rig for the weekend. I love that they showed off the towing capacity paired with the Surly trailer. THIS is what car replacement looks like.
Other details: Mounts for a 2nd battery, according to the website all mounting hardware and wires are including for dual battery (what about keys and mounting time? We don’t know..) This is only available in the US. It is size specific and the frame dictates this, not simply swapping the bars.
I’m also very excited that this will be one of the only longtail cargo bikes that work with the Surly trailer. We use the Surly trailer often at the bike shop and it will be nice to be able to use it with a longtail for more adventures!

Frequently Asked Questions
- Does it come with the bags? YES
- Can it work with Xtracycle parts? SOMEWHAT, we are testing this a bit more extensively

- Does the Yepp Maxi need adapters to work? How many fit? KINDA, more documentation coming.
- How difficult is it to install the additional battery wiring? TBD
Who Is This Bike For?
A few customers came to mind while I watched the Big Easy video.
1. The Surly lover. They have 3 Surly’s already and support the brand no matter what.
2. The Surly lover that now has kids.
3. The friend that you always invite camping because they bring the kitchen sink and extra food for everyone to eat.
4. The person that wants only ONE bike and likes to go camping.
5. The person or company that wants the ease of a longtail cargo bike because they ride like a normal bike AND the ability to pull a Surly trailer.
Why am I Excited About This Bike?
Spend 10 minutes with me as I tell you the pros/cons, and why I think this is a unique bike for the market.
