Bought a nice inexpensive phone mount you might be interested in.

Appears to be a RAM x-grip knock off, but includes a USB outlet in the base. When I bought, it was 14.99. Now showing 16.99. Way better than 50.

I through an old phone in and rode to work on some bumpy Michigan roads. Held just fine. No worries.

On the bike: Ulysses Pro Speedometer is pretty sweet as well.

Interesting. I'm not sure how I could mount it on mine, I have zero room.

I used a bolt for the handlebar clamp

Mine is similar to this. I mounted it to a Ram Ball on the brake reservoir. They have a gizillion others. I think mine was $8.00 shipped.

Thanks!

Just need a waterproof case

Waterproof case? That's why baggies were invented! This is Grassroots,after all.

I use the Quad Lock and case with my IPhone 6+ on several of my bikes.
