Best Quick-Release Bike Phone Mounts for Adult Tricycles
A quick release lets you take the phone with you, but the clamp must fit a trike's bar.
Updated · 3 min read · 3 products evaluated
A quick-release phone mount lets you press a button or twist to free your phone, so it goes in your pocket when you park the trike. On three wheels you also feel more vibration than on two, so the clamp, the silicone pads and the locking action decide whether the phone stays put.
We kept three mounts: the ROCKBROS handlebar mount, the sincetop stem-cap mount and the Lamicall frame bag that also holds a phone. Check bar or stem diameter, phone size and case thickness before ordering, because a swept-back trike bar often has a short straight section.
Short answer
ROCKBROS is our pick for most riders, with a one-second quick release, a metal clamp for 20 to 30 mm bars and a fit for 4.5 to 7.1 inch phones. sincetop mounts under a round stem cap with an adapter on the phone case, and Lamicall is a bag that holds a phone and small items.

ROCKBROS Quick Release Handlebar Phone Mount
A handlebar mount with a one-second quick release, a metal clamp with silicone grip, 360 degree rotation and a fit for 4.5 to 7.1 inch phones.
Best for
Most trike bars
Why we like it
Press the lock button and the holder locks the phone, and pinching the side buttons releases it, all with one hand. A metal handlebar clamp with anti-slip silicone holds the mount, and non-slip pads protect the phone from scratches. The handlebar type fits 20 to 30 millimeter bars, and phones from 4.5 to 7.1 inches fit.
It needs no tools and gives the widest bar range here. It clamps directly to the bar, unlike the stem-mounted sincetop, so it needs a straight bar section. A clamp-on mount is simple, though a big phone can swing on rough ground, so tighten the clamp well.

Best Stem Mount2 of 3
sincetop Q-Series Quick Release Stem Mount
An aluminum mount under a round stem cap with a phone-case adapter, a safety lock and release by rotating the phone 80 degrees.
Best for
Keeping the bar clear
Why we like it
The aluminum mount installs beneath the stem cover, in your direct line of sight, and weighs 1.76 ounces. A universal adapter attaches to your phone case, a gentle press engages the alloy buckle, and an extra safety lock holds it. Turning the phone 80 degrees releases it one-handed. The 10 degree angle helps limit sun glare.
It leaves the bar free for a bell or mirror, which the ROCKBROS handlebar clamp does not. It needs a round stem cap, so check that your stem has one, and the Q-Series parts do not match the C-Series. It suits a trike with a stem and a crowded bar.

Best Bag Holder3 of 3
Lamicall Waterproof Frame Bag Phone Holder
A 1.3 liter top tube and stem bag that holds 4.7 to 7 inch phones with a rain cover and a clamp you rotate 90 degrees to release.
Best for
Phone plus small items
Why we like it
The clamp attaches to the bike, and the bag rotates 90 degrees to install or remove. It works on the top tube or stem, measures 8.2 by 4.3 by 4.7 inches, and holds 1.3 liters. A phone from 4.7 to 7 inches fits with a thick case, and the touch-sensitive window lets you use the screen. A rain cover is included.
It carries a charger, wallet and keys as well as the phone, which the two mounts cannot. The bag adds bulk near the handlebar, and the clamp diameter range needs a check against your tube or stem. It suits a rider who wants storage and a phone window in one piece.

How We Chose These Quick-Release Bike Phone Mounts
- Quick release
- We kept mounts with a fast release, either a button, a twist or a rotate action. A mount that needs tools to remove does not suit a rider who parks the trike often.
- Bar and stem fit
- We compared the stated clamp range, 20 to 30 millimeters on the ROCKBROS, a round stem cap on the sincetop, and a clamp for a tube or stem on the Lamicall.
- Phone size and case
- We checked the stated phone sizes, from 4.5 to 7.1 inches. Phone cases add thickness, so a thick case can change which mount works.
- Vibration and weather
- We looked at silicone pads, safety locks and rain covers. A trike's three wheels shake a phone more than two, so a firm hold counts.
What to Look for in a Quick-Release Bike Phone Mount
Bar or stem diameter
A clamp grips a specific tube size, and a swept-back trike bar can have a short straight section. A mount that does not fit well will slip or swing.
Measure your bar diameter and the straight length. Compare with the 20 to 30 mm range and check clear space beside the grips.
Phone size and case
A holder opens to a certain width, and a thick case or a large phone can stretch it. A stem mount with an adapter depends on the adapter fitting your case.
Measure the phone with its case and compare with 4.5 to 7.1 inches or 4.7 to 7 inches. Check the adapter is compatible.
Release action
A release must work with one hand while the trike is stopped, and it must not open by accident. A button, twist or rotate action each feel different.
Try the action with a glove on if you wear them. Look for a safety lock so a bump does not release the phone.
Vibration on three wheels
A trike transmits shocks from both rear wheels, and a phone on a loose clamp can swing. Silicone pads cut vibration and protect the phone.
Tighten the clamp well and check it after the first ride. If the phone sags, move the mount closer to the stem.
How to Choose
By Mounting Spot
| Situation | Our pick | Why |
|---|---|---|
| Straight handlebar section | ROCKBROS Quick Release Handlebar Phone Mount | Clamp fits 20 to 30 mm bars |
| Stem with a round cap | sincetop Q-Series Quick Release Stem Mount | Mounts under the stem cap, bar stays clear |
| Top tube or stem with storage | Lamicall Waterproof Frame Bag Phone Holder | Bag holds phone and small items |
| Crowded bar with bell and mirror | sincetop Q-Series Quick Release Stem Mount | Frees the bar of a clamp |
Clamp vs Stem Mount
- Clamp
- ROCKBROS clamps to the bar, so installation takes no tools and the phone sits where you steer. It needs a straight bar section of the right diameter.
- Stem mount
- sincetop sits under the stem cap and keeps the bar free. It needs a round stem cap, and a phone-case adapter must be attached first.
Most trike riders should pick the clamp unless the bar is crowded or lacks a straight section.
For Riders with Bigger Phones Specifically
- Look for
- A holder that opens to 7 inches or more, a safety lock and silicone pads. Check the phone with its case before ordering.
- In this comparison
- ROCKBROS fits 4.5 to 7.1 inch phones, and Lamicall holds 4.7 to 7 inch phones with a thick case. sincetop uses an adapter, so case fit matters.
When to Spend More
- Spend more if
- You want a bag and a phone window together, or a clean stem mount. Lamicall adds storage, and sincetop adds a safety lock for rough roads.
- Save if
- You only need a phone holder on a plain bar. ROCKBROS gives a quick release and a clamp without extra pieces.
Frequently Asked Questions
Will a quick-release mount stay put on a trike?
A trike shakes more than a bike, so a firm clamp matters. ROCKBROS uses a metal clamp with silicone, and sincetop adds a safety lock. Tighten the clamp well and check it after the first ride.
What bar size does the ROCKBROS mount fit?
The handlebar type fits 20 to 30 millimeter bars, which covers most trike bars. Measure yours before ordering, and check there is a straight section long enough for the clamp beside the grips. Swept-back trike bars curve, so this is easy to overlook.
Do I need a case adapter for the sincetop mount?
Yes. A universal adapter attaches to your phone case, and the mount clicks onto it. Check the adapter fits your case, and note that the Q-Series parts do not match the C-Series. Slim cases tend to work best with an adapter.
Can the Lamicall bag hold a large phone?
It holds phones from 4.7 to 7 inches, including thick cases. The bag measures 8.2 by 4.3 by 4.7 inches. Check the clamp diameter against your top tube or stem before you order. Thick cases are fine, but measure the phone with its case first.
How do I reduce screen glare on a mounted phone?
Sun glare can wash out a screen, and the sincetop angles the phone 10 degrees to limit it. Keep the phone out of direct sun when parked, and remove it from the mount when you stop.
Bottom Line
ROCKBROS is the best pick for most trikes, with a fast one-handed release and a clamp that fits 20 to 30 mm bars. Choose sincetop for a clean bar or Lamicall if you also want storage. Measure your bar or stem and your phone with its case first.
