You have support for driving and public transit but not for bikes? Seems like you could get some rough estimates by using elevation variance as a multiplier for driving time.
Decent initial release, but I wish the search was more flexible.
My common use case is "I will spend $X to go anywhere for under Y days any time in the future" and I haven't found a service that makes this easy.
Kayak's "explore" page is the closest I've found, but they rarely have the cheapest flights listed and have no way to set duration. Has anyone found a better solution?
