This is a bit of a personal preference. I have a Keyboard tray attached to my handle bars so I can easily type, I have a DIY stand to my left to store my water-bottles and remotes.
It is a DIY tray. Piece of wood and a clamp. LOL. No it does not vibrate. It may not be the nicest setup but I have a dedicated bike on the trainer and after over 840 hours it still does the job and keeps me fit
I’ve first ordered this one now. I think it’s the cheapest alternative to the Zwift stand.
However, it would only be around 2cm above my bike. If I want to type, I would have to pull it closer to me as well, which probably won’t work as it has some mounting brackets at the bottom.
I can also not use it on my crosstrainer, which is significantly higher.
I therefore cancelled and ordered this one instead
It’s higher and let’s me use it on the side of my bike, allowing me to type when sitting upright.
I’ve also orderd clamps like these and will try to make my own little table attached to the handlebar.
