The Pro-User Diamant is a collapsible bike rack for 2 bikes. It's mounted onto the car's tow hitch. At 18 kilos, this bike rack isn't the lightest, but it has a large load capacity. This means you can easily transport 2 electric bikes. The bikes are attached to the frame. The rack is collapsible. Easily store it after use with the included storage bag. Since the User-Diamant is pre-installed, it can be easily mounted onto your car's tow hitch. If you've forgotten something in your trunk, simply tilt the rack and you can get that last bag out of your car. The rack has both a 13-way and 7-way connector.
