Fits any handlebar from 15 to 40 mm (0.59 to 1.57 in) — and tells you how not to break it
Lamicall Corner-grip clamp mount, locking, 198 g (7 oz)
A corner-gripping clamp phone mount with a mechanical safety latch, for phones up to 6.8 inches on handlebars from 15 to 40 mm (0.59 to 1.57 in).
What you are getting
A clamp mount gripping the phone at each corner, with a red locking switch on the back, silicone pads, four spare shims, 360° horizontal-to-vertical adjustment, for phones of 4.7 to 6.8 inches up to 15 mm (0.59 in) thick with the case, on handlebars of 15 to 40 mm (0.59 to 1.57 in). 198 g (7 oz). $15.99.
The widest handlebar range on this page
15 to 40 mm, said twice, with an instruction attached: “please measure the diameter of your handlebars before purchasing”.
Fifteen millimeters is a scooter stem or a child’s bar; forty is a fat motorcycle bar. Between them sit every bicycle diameter — 22.2, 25.4, 31.8 and 35 mm (1.38 in) — so this is the mount that fits whatever you own, where the JOYROOM on this page stops at 34 mm (1.34 in) and misses a modern 35 mm (1.38 in) mountain bar.
“The extra 4 silicone pads make your phone fit better with handlebar, can add or remove the silicone pad according to the diameter” — shims, which is how a single clamp covers a 25 mm (0.98 in) span.
The red switch is the safety catch, and the listing is blunt about it
“Phone clip must be locked by the red switch on the back so that phone doesn’t fall off while riding!”
Exclamation mark included. That is the honest version of what a corner-grip clamp is: four arms holding a phone by spring pressure, which a hard enough jolt can overcome — and a separate mechanical latch that stops it.
The JOYROOM on this page has the same arrangement and the same warning. The Quad Lock does not need one, because its lock is the mechanism rather than an addition to it.
Use the switch. A phone leaving a handlebar at speed is not a repairable event.
And it tells you how NOT to open it
“To remove or place your phone, pull out the arm at the top. Do not pull out the left or right arms at the bottom, as this may cause the gears inside the phone holder to jam, rendering it inoperable.”
Seventh bullet, and it is the most useful sentence on the listing. A geared four-arm clamp has one arm that drives the mechanism and three that follow; forcing a follower breaks the train.
No other mount in this survey explains its own failure mode.
198 g (7 oz), which is the middle of a very wide field
Kinizuxi 40 g (1.4 oz), Bone 65 g (2.3 oz), Quad Lock 87 g (3.1 oz), Lamicall 198 g (7 oz), JOYROOM 399 g (14.1 oz).
A geared metal-and-plastic clamp with a locking latch is always going to outweigh a silicone strap. What it buys is the latch and the corner grip; what it costs is 133 g (4.7 oz) over the Bone strap mount.
6.8 inches, which is the tightest phone limit here
Bone takes 7.2”, JOYROOM and the published LeMego 7”, Kinizuxi and VOVIGGOL quote 7” and 6.5” respectively. At 6.8” this is in the middle, and its 15 mm (0.59 in) case thickness is less generous than JOYROOM’s 18 mm (0.71 in).
The compatibility list runs to eighteen iPhone models and six Samsungs, which is a list of inclusions and tells you nothing about the edge.
What is not published
No retention force, no vibration damping, no waterproofing, no material for the clamp body, and no weight split. The third bullet lists phone models including ones not yet released at the time of writing, which is a listing habit rather than a specification.
