Forty grams, $7.99, and the cradle comes off the base
Kinizuxi Detachable silicone strap mount, 40 g (1.4 oz)
A silicone strap phone mount with a detachable cradle, weighing 40 grams and taking phones from 4 to 7 inches.
What you are getting
A silicone strap mount, detachable from its base, 360° rotation, tool-free, for phones of 4 to 7 inches up to 15 mm (0.59 in) thick with the case. 40 g (1.4 oz) — the lightest mount on this page. $7.99 — also the cheapest.
The detachable base is the one structural idea here
“Detachable design allows you to take your phone out without removing the entire phone mount.”
That is a two-part silicone mount: a cradle that holds the phone and a base that stays strapped to the bar. Every other strap mount on this page — the VOVIGGOL and the Bone — is one piece, so the phone comes out of the bands each time.
Why it matters: the bands are what wears out on a silicone mount, and stretching them twice a ride is what wears them. A cradle that detaches at a joint instead spares them.
Forty grams, against 399
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).
Ten times lighter than the heaviest mount in this survey, for a fifth of the price. A silicone strap with no screws, no gears, no latch and no damper has very little in it — which is both the appeal and the limit.
It names the sensors it keeps clear
“Curved silicone bands that never block the face ID, light sensor, home button and finger sensor.”
Four, where the Bone mount on this page names the front camera and the home button. The light sensor is the one others miss: a band over it makes a phone drop its screen to minimum brightness in daylight, which is the one condition in which you need it bright.
4 to 7 inches, the widest span on this page
From 4 inches — an old iPhone SE — to 7, which covers a modern large phone. Bone reaches 7.2” at the top; nothing here reaches lower than 4.
A wide span is what elastic does. The clamp mounts on this page, with their geared arms, have narrower ranges because a mechanism has fixed travel.
“Adjustable belt with close thread and nut design”
A threaded closure on the bar strap rather than a simple hook, which the listing says “firmly locks the handlebars” so that “even if you are driving on a rough road, there is no shake”.
No handlebar diameter is published — and for an elastic strap none is needed, which is the real advantage of the type over the Lamicall’s 15–40 mm (0.59 to 1.57 in) clamp and the JOYROOM’s 18–34 mm (0.71 to 1.34 in).
What it does not have, and should be weighed
No safety latch. The Lamicall and JOYROOM clamp mounts on this page both carry a mechanical catch and both warn you to use it. A silicone mount has only the elastic, and a perished band is a dropped phone.
No damping. The JOYROOM’s pneumatic damper is there to protect a phone camera’s image stabilization from sustained vibration; silicone absorbs some of that, and 40 g of it absorbs less than 399 g of damper and metal.
What is not published
No handlebar range, no retention force, no band replacement, no UV or temperature rating — silicone perishes outdoors, and nothing here says how long — and no warranty, where the Bone mount publishes a year.
At $7.99 those omissions are priced in. It is the cheapest honest way to put a phone on a handlebar.
