Hmmmmmm so might be a bit of a useless mode for us mere mortals that are unable to achieve Armstrong levels of assisted cadence and torque!!! Think I will be switching back if it doesn't work out as expected?!I'm pretty sure Tour+ only cares about your torque and cadence (regardless of Bosch marketing fluff), but the amount of power you need to put down to access higher assist levels might be more than a lot of people can do.
The first time I really gave Tour+ the beans was like nonstop interval training. It wasn't pleasant at all but I did notice to my satisfaction that the trail was rolling by without feeling the grade so much. Not that it ever felt like Turbo though. That might be out of my reach.
