We're experienced bikers who are looking to take the plunge into the world of tandems. Obviously we'd like to try (borrow/rent) several models before we make our purchase. Problem is, the captain is a stout 6'1" and the stoker is a relatively more svelte 6'4". We need a big stiff frame.
Is there a chance anyone in the Seattle area would have a large (ideally 57cm/60cm) size tandem that we could try out for a few rides?
