E-Bike Phone Holder: Make Sure the Side Clamp Reaches Past Your Phone's Thickest Point

An e-bike phone holder with side clamps holds the phone by its edges, so the jaws have to reach past the thickest part of your phone with its case on. Check that first. Then check that the bar collar suits your handlebar and leaves the controls clear, and fit it while the bike is parked.

We sell an e-bike phone holder, so read this as a shop’s notes on its own listing plus what riders say online.

Why jaw reach matters

In an e-bike forum on Reddit, one rider who replaced a slim, lightweight phone with a much larger and heavier rugged phone wrote: “It fits in the old holder OK but will jump out of it if there is too much road vibration. The side clasps just aren’t long enough to reach beyond the point of max thickness.”

That is one person’s account of a different holder, but it shows the check that matters most on a side-clamp holder. A phone can sit in the jaws and still not be held past its thickest point. A thick case or a rugged phone makes that more likely.

People want the phone there for a reason. Another rider on Reddit wrote that “it really interrupts my flow if I want to glance at my phone to see who is calling/texting, or to follow a new route.”

What our listing says

Our listing for the Gold Screw-Clamp Handlebar Phone Holder describes a “gold open phone side clamp with two curved opposing ends and black adjustment knob.” It says a “triangular cutout arm joins circular bar collar secured by two long silver bolts.”

It also notes that the phone or tablet shown for demonstration is not included.

People search for this as “e bike phone holder”, “ebike phone holder”, “electric bike phone holder”, “phone holder for ebike”, “ebike phone mount”, “e bike phone mount” or “electric bike phone mount”. They all mean a holder that fixes the phone to an e-bike’s handlebar.

Check before you buy

Our listing says to “check the actual mounting interface, phone and case dimensions, and clearance from controls before ordering.”

Turn that into three checks.

1. Your phone’s thickest point. Measure the phone with its case on at its thickest part. Compare it with the curved ends of the side clamp in the product images.
2. Your handlebar. Look at where the circular collar would sit and make sure it matches the bar there.
3. Your controls. If your handlebar carries a display, a throttle or buttons, leave room for them.

Set it up in order

Our listing says to “secure the pictured collar around a matching handlebar, seat the phone in the original cradle and secure its jaws before setting the viewing angle while parked.”

1. Park the bike. Do the whole setup with the bike stopped.
2. Fit the collar. Secure the collar around the bar, as the listing shows.
3. Seat the phone. Place the phone between the curved ends of the clamp.
4. Secure the jaws. Close the clamp on the phone and check that the curved ends sit past the phone’s thickest point.
5. Set the angle. Turn the phone to where you can see it, then check that it does not cover the display or controls.
