Description

Product Overview

The 20x4.0 fat tire gives e-bikes a larger contact patch and lower ground pressure, which improves grip on sand, snow and broken pavement. The casing is built for the higher weight and torque of motor-assisted riding.

Several tread patterns are available, from knobby off-road blocks to semi-slick patterns for city use. Bead type, rubber compound and sidewall marking can be adjusted for private label orders.
