96 reviews

Please Note:

*The 20MAXX phone cradle is part of our "MAXX" series and offers Heavy-Duty spring tension. This level of tension is specifically engineered for Mountain Bikes, e-Bikes, Road Bikes, Touring Bikes, Cruiser Bikes, Cargo Bikes, Extreme Off-Road, and other demanding applications.


  • Fits A Variety Of Bar Sizes: The included bar clamp works with 7/8", 1", 1-1/8" and 1-1/4" handlebars (bushings are included). These sizes correspond to the most common round stock bars on the market today.
  • Universal Phone Compatibility: Our phone holder is designed to seamlessly work with nearly all smartphone models, cases, and sizes. While you're on the go, it ensures a secure fit for any device, whether or not it's in a case. Capable of securely holding devices up to 3.7" wide and 0.6" thick. Please check your device for proper fitment.
  • Innovative Cradle Design: Experience the difference with our specially designed cradle. Unlike standard spring cradles, our octagon-shaped grips minimize heat transfer by pulling the phone away from the cradle's back on hot days. The spring mechanism is perfectly calibrated, allowing for effortless single-handed insertion & removal of mobile device without straining the mount base.
  • Clip-In Grips: Traditionally, our previous generation phone cradle utilized double-sided 3M tape to secure the grips onto the cradle, a method commonly employed by other brands with similar-looking holders. However, in high temperatures, the double-sided tape could loosen, causing the grips to peel away. Our Clip-In Grips address this issue.
  • Cradle Pin Sleeves Eliminate Cradle Buzz: Cradle buzz is a common issue in many of our competitors' current products. These metal cradles feature steel pins that run through them to support internal compression springs. However, the metal-on-metal contact, combined with vibrations from vehicles or motorcycles, can result in an irritating buzzing sound. We've eliminated this problem in our Enduro cradles by 'sleeving' the pins, ensuring quiet operation.
  • Premium Materials: Real CNC Machined Black Anodized Aluminum. Glass Filled Resin Knob Molded over Stainless steel threaded inserts. Stainless Steel and Aluminum Internal supports.
  • Optional Anti-Theft Knob: (PATENT PENDING) This arm, although not always necessary, has optional anti-theft features. This can (A) help prevent snatch and grab situations on your Mountain Bike, e-Bike, or other similar environments. (B) The ball cannot slip from the socket if properly tightened.
  • Color Swap Compatible: Tackform offers a wide range of anodized billet aluminum knobs. This DuraLock arm is compatible with Tackform's DuraLock knobs, allowing you to customize your setup to match your vehicle. Black knob included.
  • Tackform 20 Series: Specifically designed for compatibility with Tackform’s 20 Series Platform, revolving around the 20mm ball and socket system. While compatible with other 20mm products, our parts stand out for their tested durability and engineered load capacities, featuring a safety factor not guaranteed by other manufacturers. Please Note: Not suitable for 25.4mm / 1” / B-Sized balls.

Do not even consider buying a different brand of phone mount!!

A secure and long lasting phone mount for your eBike is NOT something you want to skimp on and boy did our new mounts not disappoint!!! They’re very easy to take on and off with one quick twist of a knob. Being a city dweller, I bring it inside with me when we lock our bikes out. I was worried about it being cumbersome to constantly take on and off but it’s a breeze. It literally does not move a millimeter, even when hitting massive Chicago potholes!! I happen to have the largest smartphone money can buy. It’s basically a tablet. It fits just as well as my husbands phone which is significantly smaller. It’s definitely my favorite thing about having a bike!!! So happy we got these!

Enduro Series

I have the Enduro Mountain Bike Mount on both of my Bikes. The 2022 Trek Marlin 6 and a Specialized Sirrus X 4.0 are hands down the best bike phone mounts on the market!

Quality and value don't often come in one package

Love this phone mount! I installed it on my e-Bike and not only is it functional but it is well made. I get no vibration as I'm running down the road and I have all the confidence that the clamping system will hold my phone tight.

Solid phone cradle

I bought this for my road bike. Now I want one for my motorcycle. This cradle is solid. It was easy to install and it doesn’t slip. It holds my phone firmly. This is a quality product.
