I am back from Aldi. I got the spin bike.
It was a tough job I underestimated its size and weight. I managed to lift it and wedge the box in the big Aldi trolley but it didn't really fit so I had to hold it with one hand while pushing the trolley with the other.
To get it in my car I had to do an odd manoeuvre which ended up with the trolley coming to rest on its side on the ground. The box only just fit in the car wedged at an angle.
A tough operation but all is well now and the box is safely home. Assembly planned for later today.
