If you have Apollo Big Boy electric fat bike (or other bike with similar dimensions), then you might wonder where to put your phone and drink, wonder no more!

This might fit into any bike, as long as the headset stem is about 30mm in diameter. Or if you resize the bracket part to fit your bike. At least here in Finland there is great website (https://jalki.fi/ ) where to get maps for exciting nature tracks for mountain and fat bikes, but maps are hard to use if your phone is in your backpack.
The handlebar on Apollo Big Boy is not in a shape where you could attach any of the existing phone holders, so I needed to innovate a little bit. This one is attached to the headset stem (I had to look it up, but that appears to be correct term for it). I also wanted to have a holder for a can or bottle, so the other side of headset stem was perfect place to put that.

To my knowledge, Apollo Big Boy is currently only sold in Finland, UK, Belgium, Canada, Australia, Thailand and in some other Asian countries. It's on a cheap side of e-bikes, but after few hundred km's I'm still happy with it. I wouldn't put 3k euros to a bike and without electric motor I wouldn't use bikes at all. I'm sure there are better bikes out there, but they are out of my budget.

Some parts like balljoint, nut, slider and tightener are made by Lucas Silveira also phoneholder and extension I remixed from his design from here: https://www.thingiverse.com/thing:4770966

The thing is modular for easier printing and so that if you later want to modify some part of it, you don't have to print everything again.

You need:
2x M5x25 bolts (or longer)
2x M5x50 bolts (or longer)
4x washer
1x rubber insert inside bracker, you could also use electric tape
4x M5 nuts, I suggest you use lock nuts, but I guess normal ones are fine too.

Edit 13.8.2021:
I edited phoneholder.stl, because on first version slider was in front of power button, version two has bracket and slider much lower leaving power button free to be pushed. I believe most phones nowadays have the power button in pretty much same place.
Also I noticed that you have to glue the balljoint to the phoneholder, otherwise phoneholder will get loose and turn into undesired angle.

Edit 1.11.2022

I made faster phone holder, which is easier to use and uses less plastic. https://www.printables.com/model/307752-faster-phone-holder-for-bike
