Tandem sizing - for a charity ride

[GrumpyGregry]

I'm 6' 2", she's 5' 1" (and blind), it's a one night only gig, riding around London for charity, and I need to source a suitable mount...

What 'size' roughly captain and stoker do we need? I'm reckoning in the region of 19" and up for me based on solo bikes but for her?

Find something to fit you. By lengthening the stem or rotating the handelbars (or fitting butterflies), dropping the seatpost and (if necessary) fitting shorter cranks the stoker size is pretty adaptable.

She might feel happier with a stepthrough frame. Whatever you ride try to have a good offroad practice first.

As long as the pilot can hold bike and stoker up (it's much more efficient stopping and starting if the stoker stays clipped in) the rear frame size is not so important. I'd guess she couldn't manage much more than a 20" (old money) seat tube even with the seat right down. You might be able to find a frame in the 21/19, 22/20 range that would suit.
