Understanding wheel Sizes.

Our smaller 20" wheels create an overall lower centre of gravity and standover height on your bike - this is great for increasing rider confidence and control as the cargo or kids are closer to the ground, making it easier to manage.

The larger full-size 24" wheels give a bigger rolling circumference, which is great for riding fast, hitting bumps and generally more heavy riding. We also keep the rear rack here as low to the ground as possible, with the very minimum clearance above the wheel.

And yes, the Ultra has a large on the front and small on the rear - its the best of both worlds!
