I have noticed it has a decent amount of vibration in the pedals when under load (200-250W). Is this just the magnets and how the resistance works? Definitely not a smooth feeling as my old Kickr Snap.
The other issue I have noticed in in Zwift, the changes are extremely rapid so for example cresting a hill the change from a positive gradient to a negative one causes the resistance to just let go and almost feels like it is slipping. I am not sure if this is normal and the switch from my power to it powering itself down the hill is that abrupt? I guess I need to try unplugging it and remove the powered downhill option.
I went from an H2 to the 2T, and noticed the vibration under heavier resistance. I attributed it to magnet harmonics. It wasn’t constant, but was different than the H2.
The changes being sudden was a surprise. I think that was more the ‘virtual flywheel effect’. The H2 would often take a bit to get up to the higher goal, and would take a bit to spin down to a lower goal. The 2T was generally like riding a flywheel equipped trainer like the H2, but at times it was a lot more harsh also. It got better with a firmware update, but was still an issue somewhat.
I also experienced a 2-second pre-change in the goal. Trucking along, and the goal jumps 50% at 2 minutes, and the 2T was always at 1:58, but it also dropped 2 seconds early too. That seemed to get better over time with firmware updates, but was a surprise. I didn’t notice it being a problem with the H2 but I think the inertia of the flywheel smoothed things out a lot. The Kickr Bike would often jump early too, but I kind of expected that after the 2T.
But there are no perfect trainers. I have an H3 backup trainer, that I have been using a lot since I bought the Kickr Bike, and it has some idiosyncrasies too. I swear it will be on the nose for changes, and then all of a sudden lag on some, plus it gets really hot often but hasn’t quit because of overheating, yet.
I love the smart trainer concept. I was usually bored into torpor on a mag trainer, but all of the drama with failures and quality issues has proven to be a major distraction from riding. I just want to ride my bike.
EDIT: One comment on the Kickr Bike: The shop sold 2 bikes the same day. Mine, and another one. Mine squeaked, creaked, popped, and the shifters died. The other bike, ridden probably more than I rode mine, has experienced no problems at all. None. Weird…
