Surly Bike Covers — Big Dummy & Big Easy
Surly was hauling kids and cargo on steel longtails long before e-cargo bikes were everywhere. The Big Dummy is now a legacy model and the Big Easy added a Bosch motor to the same idea — both are bikes people keep for decades, which is exactly the kind of bike worth protecting outside.
Which BikeParka fits your Surly?
| Model | Length (circa) | Recommended cover |

Child seats, bags, decks and other accessories can affect the fit. Running an unusual setup? Send us your exact model and accessories and we'll check it before you order.
Every BikeParka cover is made from waterproof ripstop with taped seams and has lock slots, so you can lock cover and bike together. Adjustable toggles cinch the cover down in wind, and each one packs into its own Stuff Sac.
Longtail cover sizes
The BikeParka Longtail and Longtail WS both fit bikes up to approximately 210cm long with handlebars up to about 80cm wide. The WS is cut wider and taller at the rear to clear fitted child seats.
Surly cover questions
Which cover fits the Surly Big Dummy?
The BikeParka Longtail WS with a rear child seat fitted, or the standard Longtail without. Surly doesn't publish an overall length for the Big Dummy, but its longtail shape sits within the Longtail range for most builds — message us if your setup is unusual.
Which cover fits the Surly Big Easy?
The Big Easy measures around 224cm, which is past the Longtail cover's approximately 210cm recommendation. Message us before ordering and we'll advise on the best option for your build.
Is the Big Dummy still made?
Surly lists the Big Dummy as a legacy model, but there are plenty on the road and secondhand — the covers fit regardless of the year.
