Carrera Vengeance Bicycle

Have two bikes to sell. Descriptions of the bikes can be found here: https://www.halfords.ie/bikes/mountain-bikes/carrera-vengeance-mens-mountain-bike-2020---black---xs-s-m-l-xl-frames-340910.html Originally bought for €500 each during the pandemic (1x Small Frame & 1x Large Frame). Used about 3 times since bought, otherwise kept inside a shed since. (Large Frame bike needs to have back brakes checked. Tension is gone since sitting for so long) Selling for €350 each. But, if taking both, will be happy to give them for €600. Will give helmet and lock with the bikes. Bottle holder already attached to both bikes.
