The weight of an electric wheelchair will depend on each individual model. We made sure to list this as a spec in each of our picks, but our favorite models range from 49 pounds to a little over 150.

It's also possible to just get two Revolve wheels, that can be swapped onto a third-party folding wheelchair. They go for €2,838 ($2,995) a set (retail $3,500).

Most electric wheelchairs aren't designed with portability in mind, but Whill's new Model F can collapse down for easy transport when not in use.

For now, the design partners are focused on accommodating power chair users first. “It’s the hardest one to get on board. Let’s try and get the electric one in,” MacInnes said.
