A cooler includes a main body which includes a base, an upper rim, and one or more cooler walls extending therebetween. The cooler in some embodiments further includes a removable wheel assembly which includes two coaxial wheels, and an axle. The two coaxial wheels are removably securable to the axle. The cooler still further comprises a wheel fastening system configured to secure the removable wheel assembly to the base of the main body which includes a mount, a clip hingedly connected to the mount, and a locking clasp configured to lock the clip into a closed position to secure the wheel assembly. The cooler yet further comprises a lid including two wheel storage recesses, each being sized and dimensioned to receive and retain one of the coaxial wheel of the wheel assembly, and an axle storage recess sized and dimensioned to receive and retain the axle of the wheel assembly.
