This model of carrier is now discontinues by Witter. They are replacing it with a new model which should be available March 2019.
The Witter ZXE502 is a genuine 2 e-bike carrier with a payload of 60Kg that fits to the tow bar. The two features that make it an e-bike carrier are firstly the aluminium cross rails are set further apart to take account of the extra size of electric bikes and secondly a loading ramp is supplied as standard so you do not have to lift the bike on to the carrier. The carrier is also suitable for downhill or large suspension bikes.
The carrier is supplied fully assembled. It is then loaded vertically on to the ball hitch and can be locked into position. It can be left on the car in this stowed position with the number plates and rear lights in an upright position. The lights are plugged into the vehicle’s system and both a 7 & 13 pin adapter is supplied.
For use, the carrier folds down from the vertical to horizontal and locks into position.The cycle support arms can be taken off and positioned individually to suit your bikes. The tyre racks are adjustable and the wheels are fixed with straps.
With both bikes fixed, if you want access to the rear of the car, the bikes can be tilted forward to give room for the boot lid or tail gate to open.
