Just bought the Wahoo speed and cadence monitor for my Nero sport Bluetooth spin bike. Bought on Amazon so can always send back if it doesn’t work in increasing my ‘W’ number.
Did you get your sensors, how did they do? Where you able to mount the speed sensor directly on the wheel and does it help with getting better reading?
I’m in the same kind of situation as you, where I can’t keep up due to low watts.
