Most people think of the BMW i3 as a small city car, but the most common comment I get when people get inside is that they think it is bigger than they thought.
The i3 is not suitable to take for long journeys but it has plenty of space for your city adventures. Adults sit comfortably in the back seat even if it can be tricky to get out of the rear suicide doors if parked close to another car.
The boot is 260 litres, which is enough for the trip to the grocery store. However, with the back seats folded you will have 1100 litres and it is not bad for a small electric car.
I love biking and have put my bike in the i3 many times. There is no need to disassemble the bike before storing it in the back, just put it right inside. Watch the video and see that you will be able to fit it inside in a few seconds.
