⚡ At a Glance
  • Mounting Security: Stretchy silicone straps and a buckle grip handlebars tightly to prevent slipping
  • Best for: Cyclists and riders who need quick phone access for navigation and calls
  • Not ideal for: Phones wider than 4.0 inches, which may not sit securely in the straps

Detachable silicone-strapped mount fits most 4 to 6.7-inch smartphones and clamps to handlebars 18 to 35 mm. A 360-degree swivel supports portrait and landscape viewing, while tool-free installation makes removal quick and simple.


Stable grip on rough terrain – thanks to silicone straps and buckle

Stretchy silicone bands wrap around the handset and hook into a silicone buckle, while a built-in silicone pad increases friction against the handlebar. The silicone material resists slipping even when riding over uneven surfaces.

Secure silicone grip keeps the phone in place on bumpy roads, reducing the risk of drops. Riders can trust the mount for urban commutes and gravel tracks alike.

Flexible viewing for navigation – with 360-degree rotatable mount

A swivel head allows full rotation for portrait or landscape orientation and fine angle adjustment, so the screen can be positioned for glare reduction and comfortable sightlines. The mechanism locks into position once set.

Easy angle changes make following maps or using cycling apps straightforward without stopping. Quick adjustments let a passenger or child also view the screen when needed.

Fast removal when stopped – with detachable, tool-free installation

Tool-free silicone buckle secures the mount to handlebars sized 18 to 35 mm, and the phone cradle detaches without undoing the entire mount. The design allows the phone to be removed while the base remains fitted.

Grab the phone for calls or photos in seconds, then reattach the cradle without tools. Handy for short stops, shared bikes, or leaving the phone with a stroller or shopping cart.
