It can be tilted, but the XT3 is only for three bikes. I wouldn't have the courage to tilt the carrier with 3 e-bikes mounted. In my experience, it is very difficult to mount the third bike on an eMTB because you can hardly get past the two bikes that are already mounted, especially for children's bikes.

The easy Fold xt3 can be tilted and is ideal for 2 heavy e-bikes.
