Do you have a power meter? I have a Tacx Vortex, which is a lower model than the bushibo and has been fine for my use. However, both the Vortex and Bushibo use virtual power which can wildly vary dependant on temperature or tyre pressure and so it hard to get consistent power values from it. If you do not have a power meter then i would suggest the flux or direto which i understand are a lot more accurate as they are a direct drive rather than wheel off trainer like the bushibo or vortex.
