I notice that DJI and some other makers of bike mounts do not mention the Osmo Mobile.

I am using mine with an iphone 6S.

Is the DJI model the one to buy (about 45 dollars) or will some of the regular clamps sold on Amazom ($15) with 1/4 take-offs (for action cams) be able to do the job? I'm fairly handy so don't mind making mods, etc. - just want the best way to do this.

Earlier on this forum, there were some poor reviews on the DJI model (vibrations) when paired with the Osmo Mobile. Is this still the case?

Hello Sir, sorry that Bike Mount in online Store is not compatible with Osmo Mobile.
Osmo Mobile works fine with iPhone 6S, if there is any problem, welcome to post here.
