I think the Ibike is great or hopefully a pedal based system that will still be expensive but will also work on the road bikes.
And if I were going to use a crank based system and figure out a way to "make it work", I would use the Quarq. We have this technology on road bikes and it works well for less money than an SRM.
I posted more for the gee whiz of look how much this stuff costs. I was pretty sure that cheaper solutions were available.
I like seeing the power output from other people. I know my power will be similar and I get that information for about zero cost
Good luck with it. I'd like to see progression numbers over a training season.
This was a good read on the subject.
