TLDR: I love my Bike+ as does my partner. It's well worth the monthly fee (and this document seems to imply that its too cheap!). Is the bike itself worth £2250? Probably not in theory but it is to me.

Further elaboration: The tech is interesting. It's very polished but there is SO much room for additional reporting, functionality etc. I have actually played abit with the unofficial API and theres lots of data available.
