Whats the cheapest way to slap a power meter on a BMX bike without breaking the bank? Im talking bottom-dollar, bare-minimum options here - no fancy-pants, high-end stuff. Can you really get a decent power meter on a BMX for under $200, or are we talking pipe dreams? Are there any reliable, affordable options out there that wont sacrifice too much in terms of accuracy or functionality? Also, whats the most cost-effective way to install a power meter on a BMX - crank-based, pedal-based, or something else entirely? And dont even get me started on compatibility - are there any power meters that can handle the unique demands of BMX riding, or are we stuck with road-bike-centric options? Spill the beans, folks - whats the most affordable power meter option for a BMX bike?
