If you’ve been shopping for a cargo ebike, you may have noticed something interesting—many of them have smaller wheels, like 20-inch, instead of the more common 26" or 27.5". So why is that? Are small wheels really better for carrying heavy loads?
Actually, yes. There’s solid engineering behind the choice, and here’s why smaller wheels often make more sense for cargo bikes:
Lower Center of Gravity means More Stability
Smaller wheels bring the bike’s center of gravity closer to the ground. That’s a big deal when you’re hauling groceries, tools—or even your kids. A lower center of gravity makes the ride feel more stable and balanced, especially at low speeds or when starting and stopping.
That’s why many longtail cargo bikes or bikes with front and rear racks come with 20" wheels.
Better Maneuverability in Tight Spaces
Smaller wheels mean a shorter wheelbase, which makes the bike easier to handle. If you’re navigating through city traffic, making tight turns, or parking in a cramped space, a more compact bike can be a huge advantage.
For urban riders and delivery workers, that agility really comes in handy.
Stronger Wheels for Heavy Loads
Smaller wheels are often tougher. The shorter spokes and tighter build reduce flex and make the wheels more resistant to bending under heavy loads.
That translates to better durability over time—especially if you're regularly carrying a lot of weight.
Any Downsides to Small Wheels?
While small wheels have a lot going for them, they’re not perfect for everyone:
Less comfort on bumpy roads – Smaller wheels don’t absorb bumps as well as larger ones.
Lower top speed: They can feel slower on long rides.
Less space for tall riders: If you're tall, small-wheel bikes might feel cramped, depending on the frame.
That said, many cargo eBikes make up for this with wide tires, front suspension, or extended frames to create a smoother, more balanced ride.
When to Consider Larger Wheels
If you're planning to ride longer distances, tackle rougher terrain, or just want a smoother ride, look for cargo bikes with 24" or even 26" wheels. They roll over bumps more easily and offer a more comfortable ride—but keep in mind, they may sit higher off the ground and be harder to handle when fully loaded.
A well-designed 20" cargo eBike with 2.8"–3.0" (or wider) tires can still deliver excellent shock absorption and stability—great for complex city streets or light off-road trails.
Meanwhile, 24" wheels offer better rollover performance. Paired with a powerful motor, they can handle mixed surfaces like gravel or uneven suburban roads with ease.
There’s no one-size-fits-all when it comes to cargo eBikes. Small wheels bring stability, strength, and maneuverability—especially in urban settings. But if your rides are longer or rougher, don’t overlook the benefits of a slightly bigger wheel.
