Driving system within the wheel
Second-generation thin type miniaturized motor installed directly in the wheel.
Specifically developed for the BMW i3, the Bridgestone Ecopia EP500 is the first tire to feature ologic technology: a tire with a large diameter and narrow tread pattern.
The tyre provides high grip on both wet and dry road surfaces. It combines large diameter with a narrow tread and high inflation pressure to minimize tyre deformation around the contact patch to reduce rolling resistance. The narrow tread reduces air resistance. Grip performance on wet roads is also improved due to the combination of an exclusive newly developed tread pattern and an exclusive new tyre compound.
