Got a Flow Smart….regarding the 6% incline thing….for a relatively unfit rider like myself I find it fine on Zwift.
Zwift is set to default ‘realism’ (50%) and the mountain still gets me nice and sweaty….you can always change gear if it feels too easy.
I had a few issues with the first ones, but I got there eventually. Just check that the qr skewer and bolts are in the box – the first two I had didn’t….
Then I bricked two units doing the firmware upgrade. Tacx reckon I was ‘unlucky’…
They sorted me with another unit pre-loaded with the latest firmware and it’s been fine since.
I pair mine using a cheap usb ant+ dongle and also use a Garmin cadence sensor from my Edge 500…
Regarding durability….the chassis, casing, roller etc seem to be the same as used in more expensive units like the Vortex Smart…so you might not,get a more reliable/durable Tacx by buying the next one up….
Since my original problems, mine has been fine. I’m not very powerful or heavy though….73kg and probably struggle to break 500w for more than a few seconds….
