I bought the Bike+ when it first came out, and yes at high cadence (110-130), the screen does wobble a bit. Doesn't bother me, but I can see how it could bother others (I tend to ride high resistance, lower cadence any way). Personally, if I had to do it all over again, I would still get the Bike+ for the digital calibrator, the better sound system, the rotating screen (which is very useful for non-cycling workouts), and the auto-follow feature (which I use all the time). The smaller differences, are not as crucial, but I really like and use them too: USB C port to charge my phone (much faster than USB A) & easier and stronger lock knobs on the seat and handlebars. (I have heard stories of the original bike levers breaking)
