Like others, I have also voiced my feeling on JBV when I had constant Wi-Fi dropouts, 1/2 cadence readings etc. I reached out to JB support as I was willing to work with them in order to address issues.
For me, support was responsive and have kept me up to date with preview firmware etc. After every update I have informed them what I experienced.
I am now running preview version 04_13_01 and my Wi-Fi drops and 1/2 cadence readings are now addressed. I have been using Wi-Fi connection for the last week and it has stable.
It was also stable in later 04_12 preview versions.
Virtual gearing is working great and the trainer is quite responsive when in ERG and SIM mode.
I took a risk moving from a Neo 2T (motion plates), dedicated bike and Zwift play controllers to move to a trainer that is €450.
For €450 I feel this trainer is awesome in comparison to original RRP of €1300 for a Neo 2T.
I sold all previous equipment (Neo 2T, motion plates, dedicated CX bike for indoors and play controllers) and for the same money I have bought the JBV, Zwift Ride Frame, Turbo Rocks Realplate react rocker plate and Vacmaster 54 fan.
I am much happier with my new setup and I am glad I worked with JB support to make them aware of issues and allow them some time to address issues us users are experiencing.
I hope everyone else’s issues get addressed and if there are hardware issues, I am sure JB support will honour either a refund or replacement trainer.
