    Heavy duty phone holder for a variety of phone sizes

    Holds an iPhone 12 mini and a iPhone 13Pro max well with or without a case. Highly recommend because it’s not flimsy

    Glad this item was a match Ket! Thanks for the review.

    Doesnt' fit 500 (and others too?)

    Ordered to go on new 500. Doesn't fit on tapered handlebars as others note; covers/hits the aventon screen (even if screen mount pushed as far the left as possible3 (gains only about 1/8th of an inch anyways)). There must be a reason the pictures on the aventon web page here show it only on bikes without an visible aventon screen. It wont fit on stem either in a way to see it. It might fit on crossbar, but i've got the water bottle there and a lock to go there probably, and probably down too low to see well. the mount is rugged, well made, lots of attachment options and i use one on a cannondale quick 5, but not on this bike. Will try another mount off a third bike (a Giant), the band style...

    Does the job, no need for another.

    Holds the phone well, mounts it just fine. No need or desire for any other.
