Great item
Got the cup holder put on and it looks great. I am waiting on the 20oz cups for them now.

The cup is too tall - hits handlebar
The holder was really easy to install. it is a bit of an annoyance to get the parking brake once it is installed. I just wish the holder was a little bigger in diameter so it would hold more commercially available cups. I purchased the cup with the holder but it is too tall. when it is fully seated in the holder. the top of the cup hits the handlebar when ever you turn left. My Contigo cup will fit in the holder but it is tight very tight, not sure how much it would take it break the holder since it's just plastic. it will hold a half liter bottle of water with no problem. I'm only giving it three stars because of the diameter is small. and it sit to high with the cup in it to be used safely with out further having to mod the ryker.

Mount
Easy to install. My handle bars won’t clear it if I have the cup in it. I need to install risers. It can’t be adjusted down to create room because if the parking break.

Works great
The cup holder works and looks great. I should have gotten it sooner. It’s a-little pricey but when you don’t have to stop to take a drink it’s really worth it in the long run.

Excellent product for your ryker
I love using the bottle holder, it may be useful.
