Will the magnet hurt my phone?

NO. Manufacturers have been using magnets in phones and tablets for years and now even Apple uses magnets right inside of their phone with their new MagSafe magnets. Our specially designed rare earth magnets are proven safe for all smartphones and tablets. In a product overview from MacWorld they said, "magnet-based accessories are safe to use on iPads and pose no threat of scrambling interior electronics.” Our magnets will not harm your credit cards either. Magnets will only affect spinning hard drives found in old laptop and desktop computers that are rarely found in 2021. The magnet may affect a hotel key but then again what doesn't?

Will the mount scratch the back of my phone?

No. The mount locks inside the case but never touches the phone.

What is the purpose of the magnet?

The magnet acts as another safety feature and equally important it reduces vibration so you can clearly see your phone while riding. No rattling, blurring, or twisting like some other mounts.

Does the case protect my phone, and will it work when it’s not on the mount?

Yes. All of our mountable cases are extremely protective and are keeping phones safe every day all over the world.

Will the mount work with my existing case or cover?

Yes. The mount will work with any Rokform mountable case that has our Twist lock on the back. If you have another brand of case or no case at all you can still use our mount by using our universal adapter.

Does the bike mount include the leash (lanyard)?

Yes. All of our bike mount kits include a quick release heavy duty lanyard that acts as a third layer of security for your phone. Plenty of our customers use and love it on an off the bike. Wrap it around your arm or wrist and prevent accidental drops.

How much does the Pro Series bike mount weigh?

82grams or 2.9oz.

Do you supply a waterproof cover for the phone?

No and thankfully all modern iPhones and Samsung Galaxy smartphones are now water resistant so there is no need for clumsy ponchos, skins, wraps, bags or covers on your phone. Take advantage of the technology that you paid for with your new phone and enjoy it with your new ROKFORM Pro Series bike mount.

What other accessories will work with the case that comes with the bike mount?

All of them. Not only do we have bike mounts we have motorcycle mounts, suction mounts, universal magnetic car mounts, universal twist lock mounts, golf shooter, belt clips, stands, stroller mounts, wall mounts, vehicle mounts, sport magnetic rings and more.

ROKLOCK™ TECH

Keeping your phone in your pocket while you ride is a risk. Why take the chance? The Rokform Pro Series V4 Bicycle Stem Mount keeps your device secure with a dual retention lock system featuring our easy-to-use RokLock™ Twist-Lock and magnetic technology. We even include a heavy-duty Rokform lanyard to wrap around your stem bike mount for extra assurance.

HANDS-FREE AT ITS BEST

Whether you want to manage your favorite playlists, screen your text messages, or map your route via GPS navigation, our bike stem mount phone holder gives you convenient accessibility. It fits perfectly around your controls while remaining in view so you can use your hands to steer, signal, and gesture (kindly!). No more digging into your pockets to stay connected and safe throughout your ride.

BIKE STEM MOUNT ADJUSTABILITY

An immobile bike stem mount is a dead end. Every biker prefers a stem mount that offers a full range of motion, which is why ours lets you adjust your phone from -20 to +55 degrees. Get the right viewing angle every time via an aircraft-grade stainless steel screw that is easy and safe to use. Our stem bike mount is more than just a holder for your phone; it's a third arm!

BUILT TO LAST

The Rokform V4 Pro Series Bike Stem Mount is CNC-machined from 6061 T-6 aircraft-grade aluminum--so it stands up beautifully to the rigors of serious cycling. Along with being military-tough, our stem bike mount is impressively lightweight, blending seamlessly with your bike's frame, and won't weigh you down no matter where your next adventure takes you.

EASY TO INSTALL

Install our bicycle stem mount phone holder in minutes and get you back on the trail quickly. Fits bikes that accept 1-1/8” threadless steerer tubes, which includes most road and mountain bike (MTB) models. With a Rokform case or our Magnetic Universal Adaptor, your phone also locks in in seconds to our bike stem mount - with unparalleled security and durability.

FAQ

How Do You Install a Bike Stem Mount?

You can install Rokform's bike stem mount phone holder on any bike that accepts 1-1/8” threadless steerer tubes. All you need is the included tool with your bike stem mount. Attach the mount to the center bolt, move the phone holder to your preferred position using the adjustment screw, and twist your phone on to the RokLock™ mount. You're all set and ready to go on a journey.

What are the Benefits of Using a Bike Stem Mount Phone Holder Over Other Options?

Keeping your phone on a Rokform bicycle stem mount phone holder is much safer than relying on a cheap plastic bike mount. We use machine-grade aluminum to protect your phone from damage. And your phone is far more likely to slide out of your front pocket than to be jarred loose from our patented RokLock™ phone mounting system.

How Secure is the Rokform V4 Pro Series Bike Stem Mount?

When you use our V4 bike stem mount, you can be sure your phone will remain attached. Rokform phone cases come with a RokLock™ mounting system that lets you put your phone on and off the mount with a simple twist. And for added protection, our V4 Pro mount uses powerful N52 neodymium magnets to further hold your phone in place.

Do I Need a Rokform Case to Use this Bike Phone Stem Mount?

The V4 Pro stem bike mount uses our patented RokLock™ technology to keep your phone securely in place. RokLock™ mounts work with any Rokform case. You just twist on and your phone is firmly in place, with plenty of mobility to find the perfect screen position. Rokform cases offer military-grade protection and are popular with active duty military personnel and first responders. If you don't have a Rokform case, our Magnetic Universal Adapter attaches to any case and lets you take advantage of all our premium accessories - including the V4 Pro Series Bike Stem Mount.

How Adjustable is the V4 Pro Series Bike Stem Mount?

Every cyclist has a preferred viewing position. You can adjust your phone viewing angle from -20 to +55 degree on our V4 Pro stem bike mount. That gives you lots of choices for GPS navigation or changing playlists and stations. And Rokform uses aircraft-grade stainless steel screws to ensure your mount stays flexible longer.

What's this Rokform Bike Stem Mount Made Of?

Rokform makes its bicycle stem mount with tough but lightweight aircraft-grade 6061 T-6 aluminum. You don't want a lot of extra weight slowing you down on the road or on the trail. But you also want a mount that stands up to jolts and strains without damage. Rokform mounts, like our cases, are built with active lifestyles in mind.

Can I Still Use Your Bicycle Stem Mount Without a Rokform case?

Yes! Although our bike stem mount phone holder is designed for use with RokForm phone cases - our Magnetic Universal Adapter allows you to take advantage of all our durable accessories. With RokLock™, your phone stays securely mounted even over bumpy trails. But our cases have more to offer than just RokLock™ mounts. We make our phone cases with tough polycarbonate and shock-absorbent TPU for military-grade protection against drops and falls.

Reviews

V4 Stem Mount

"Probably best mtn bike stem mount on the market right now. (2026)"

— Ernie V. (4/5)

Works great on my road bike

"This combined with a Rockform case works great. With magnets you get in impeccable stability on the stem. Used today for the first time and contributed to a wonderful ride."

— Jeff S. (5/5)

Solid!

"Honestly, I was hesitant about dropping $70 on a bicycle mount. But we know, you get what you pay for. The construction, quality and feel, is just as solid as the phone case. Gives me comfort in knowing my phone will be sufficiently protected. Also comes with a lanyard for extra security. I wish it was easier to adjust the angle on the fly if out riding. May have to find a way to store the allen key on the bike if needed. Can't wait to use it when weather warms up a bit. Should make the bike rides more enjoyable, and less taxing, with on-board entertainment."

— Jermaine T. (5/5)

— Chris M. (5/5)

"Excellent quality and a secure connection you can trust over rough tracks. Suggest also getting the anti vibration device as well though if you have an expensive phone."

— Kat (5/5)

huge upgrade

"I am new to cycling, and having my phone VERY securely attached to the stem is awesome. I have the ability to navigate my route super easily while I learn new routes and I have no doubt it will fall off. very simple but great upgrade to the riding experience"

— Jimmy S. (5/5)

"The part that attaches to the case rubs on the back of the phone, I added some felt so the mount wouldn't scratch the phone."
