If anyone who wanted these loses out and wants an alternative in the same
price range, we bought 2 Citizen folding bikes for $199 each. They are the
Miami model. We take them camping, fold them up and throw them in the back of our pickup. Comfortable, 6 speed bike, also weighs 32 pounds. We upgraded to the comfort seat for an extra $18 and it was
money well spent.

Dahons were a little pricey for us and these proved to be a nice alternative. They're not
aluminum though so can't say how they'll hold up in the
marine environment over the long haul. Probably as good as anything else if you don't carry them on
deck exposed to the elements or in a damp locker.
