With the looming approach of cold weather, thoughts have sadly turned to indoor trainers. I was curious if anyone knew of a direct drive trainer, i.e one that you take the rear wheel off, that would take a tandem's 145mm spacing?

thanks,

I would think that you would be better off using single bikes as your training requirements will differ. My ftp is way different from my petit stoker.
For the price of a kickr or neo you could buy a couple of cheaper trainers or the new elite trainer looks good value for money.
DCrainmaker is the best source for reviews on how trainers work
Shane Miller is also a good source

Just make (or get made) a top hat shaped spacer to go on the left hand side of the trainer and fit a long skewer. It should work on any of the direct drive trainers.

Yes I am having the same very sad thoughts of boredom and sweating indoors.
Even here in San Diego the combination of dark and cold after work becomes too much.
We use a Kurt Kenetic leaving the back wheel on.

we use the Tacx Vortex smart trainer with zwift and it is enjoyable
