I've made provisions for storing inside my Class B two folding e-bikes I once had my eyes on. I can, but I doubt I will now since I am on a blood thinner and now have no desire to ride a bike. I've been a hiker all my life. Why change. The conceptual design and the reality. Those are adjustable shelves. I could remove one and still carry bikes. Alternately, one can modify and hang two full sized bikes in that space.
