What are the specific design and installation considerations that would need to be addressed in order to successfully integrate a power meter with a penny farthing recumbent bike, particularly given the unique crank and wheel geometry of these bikes? Would the existing power meter designs, which are typically optimized for traditional road or mountain bikes, be compatible with the larger wheel diameter and slower cadence often associated with penny farthings, or would they require significant modifications or custom designs? Furthermore, how would the recumbent position and potential variations in rider weight distribution affect the accuracy and reliability of power meter data on these types of bikes?
