I've loaded this trunk with groceries, a laptop bag, and even some gym gear. It handles everything well and still feels stable while riding. Great accessory if you actually use your bike for everyday transportation.

The trunk is much more useful than it looks in the photos.
I honestly didn’t think I’d use the rear trunk that much when I ordered the bike, but it’s turned out to be one of my favorite features. I use it for groceries, my work bag, and even random errands around town. It’s surprisingly spacious and saves me from carrying a backpack all the time.
I use it for all kinds of things now. Sunglasses, tools, rain gear, snacks—you name it. It’s one of those accessories that becomes more useful the longer you have it.
I keep a small tool kit, gloves, charger, and a few personal things in mine. It’s nice knowing I can leave those things with the bike instead of moving them around every time I ride.
The trunk has been really useful for carrying everyday stuff. I can fit quite a bit inside, which is exactly why I bought it. Just keep in mind that it does add some size to the back of the bike, so I had to get used to parking it with the trunk installed.
I keep my lock, charger, and a few other essentials in there, and there's still plenty of room left over. So much nicer than stuffing everything into a backpack — my back thanks me every ride.
Really happy with the quality of the rear trunk. It feels solid, stays secure while riding, and gives me plenty of space for everyday items. Definitely gets used more than I thought it would.
One of my favorite things about this bike is the rear trunk. It's convenient, secure, and makes everyday riding a lot more useful than a standard bike.
Having the rear trunk means I don't have to wear a backpack everywhere. It's a small thing, but it makes riding a lot more comfortable, especially on longer trips.
Great for shopping and running errands but bike looks better without it, just personal preference.
The Ebike Multifunctional Rear Trunk is a fabulous addition to the Emma 3.0, the compartment pocket fits a mobile perfectly and the lockable function gives great security.

This trunk is so cute! It’s very spacious and I love that it can lock! No, it’s not going to keep a serious thief out so don’t put anything valuable in there and walk away, but the lock is definitely a deterrent! It’s big enough to store my bike helmet, jacket and riding accessories or a few groceries from the store. No, I do not use this to carry my 25 lb dog! He’s just there for size reference! He did think it was more stylish than his milk crate basket though!
