I'd first want to know where I can store it aboard (and on deck is not an acceptable option - at least from my perspective) and how I'm going to get it into and out of the dinghy, etc. Just one person and 1 bike might make for a full 9-10' dinghy: I'd want to know there was extra room for other items. Even when folded, bikes can be awkward aboard the big boat and a dinghy.
