I bought this for taking to bass lessons along with a TC Electronic BAM200. For sure, the box is small, albeit weighty. You could probably just about strap it to the rear rack of a scooter.
Be under no illusions that this cab performs some kind of miracle that makes it sound like a 12" stacked on a 2x10". It doesn't. You get no feeling of air moving or low end.
That said, with a small class D amp like my BAM200 it's fit for purpose for portable practice, lessons, packing with your Steinberger Spirit to take on holiday, etc. Loud enough but "thin".
If you can afford the extra space when travelling, consider a TC Electronic 2x8" which I think is a fair bit cheaper, weighs about the same and has a lot more low end.
