Power meters are too expensive to put on all your bikes - the overarching problem is bikes need more innovation and time is ready for a shift to mechatronics.
SENSITIVUS (b2b) & Team ZWATT (b2c) develops and sells advanced bike sensors to help riders get valuable training data from all their bikes without having to move expensive power meters from bike to bike. Subscription based HW and focus on low mfg costs allows quite aggressive pricing.
A very experienced team with a bootstrapped and exit-ready business + revenue from 2b2 and potential to scale b2c (and b2b) makes this an interesting case.
