sincetopBike Phone Mount,Mountain Bicycle Stem Phone Holder,Aluminum Handlebar Cell Phone Clamp,Gravel/MTB/Road E-Bike Cycling Cell Phone Clip,Quick Release Attach/Detach-Black【Series C-1st Gen】

This road bike phone adapter has been a total lifesaver on my rides! It keeps my phone securely in place and makes it incredibly easy to grab when needed. Having a constant view of my cycling stats right there on my phone is fantastic. Highly recommend this for any serious cyclist.

Good product, sticks well too an inexpensive

Yes this works very well on the girlfriends race bike…

Inexpensive way to slap your phone on your bike. My bike's stem is.. Special(ized) so I was not able to use the top tube compression plate and bolt to mount, but some creative use of zipties allowed me to get a very sturdy affixation to the stem; I'd love to see yet another version that has some type of flexible, completely custom mounting option.The adhesive on the mounting plate that you stick on your phone's hard plastic case is the good stuff, and if you follow the directions/best-practices for surface prep, it's on there for keeps.There's some high-end bike-shop type product similar to this that costs twice as much... this costs half as much and works every bit as well, as far as I can tell.I bought three and will buy more if needed. The only downside is it may become discontinued in the future, as my previous mounting solution had, so I'll have to throw all this away and move to whatever China comes up with next.I rode about 15 miles over unmaintained, bumpy city streets without realizing I forgot to flip the lock lever up, and the phone stayed put, so that's a bonus. They also include a little strap so if your phone case has a lanyard loop, you may use that for an extra layer of oopsie-prevention.Update:Subtracting one star for durability. It's pretty easy to accidentally break the little lever off, making the unit completely unusable. If you sometimes flip the bike onto its bars and seat to do work on the bike, take care that this phone mount does not make contact with the ground. Slightest force may break it...

Works well

I have been looking for a phone holder for my mountain bike for some time now. All the holders I have seen attached to the handlebars which I am not excited about being afraid of the mounting nut and bolts loosening after some time and forget to check before heading on a trail. I come across this phone holder that mounts to your handlebar stem. I liked the place meant and the fact that it mounts with existing bike part ( stem bolt). So, I bought it.Mounting was easy, only took two minutes making sure it was perfectly aligned. The 3m adhesive mount that you attach to the phone or case is really strong. I attached my phone to the mount and flicked the lever to lock the phone in the mount and gave it a couple of stress tests pulling and bending. After I unlocked the phone flicking the level to inspect. Not one mark no signs of stress marks or damage on the plastic holder on the phone case. The mount also showed no signs of damage or stress. I attached the phone to the holder and went for a test ride of an bumpy dirt trail. Even after all the wrenching I did to the mount, the mount and phone was still tightly secure not even a wiggle in the connection point. This is the best phone hold mount and sleekest. Definitely worth buying if this the type of mount you like and are looking for. I highly recommend this mount.

I had high hopes for the sincetop Series C-1st Gen phone mount (stem mount version), but it has not proved to be either durable or safe for holding my phone on my road bike. I cannot recommend it for holding a phone on a bike under any circumstances.I'm one of those people who reads manuals thoroughly before and during the installation and use of products that I purchase. I read all of the material that came with the Series C-1st Gen phone mount and additional information on the sincetop website before installing the system on my Trek Emonda road bike. I also purchased a phone case that met the specs required for use of the system (polycarbonate with a smooth back for attaching the adapter).The installation on my bike went smoothly and quickly. I attached the adapter to the case and let the adhesive set up for a day as recommended. For the first couple of rides, I didn't experience any problems, but within a couple of weeks, the phone began releasing spontaneously from the mount. I couldn't find any cracks or defects on the mount or the adapter, but the problem just kept getting worse. Eventually the phone would release from the mount even on the smoothest roads.I have contacted sincetop about the problems I've experienced and offered to try their most recent mount (Series Q) to see if that would solve the problems. (I also offered to pay the difference in the cost of the Series C and the Series Q) They have not responded to my emails. Obviously, I'm very disappointed with their product and their customer support and cannot recommend this company or its products.

This bike phone mount is a reliable and solid option for securely holding your phone while riding. The aluminum construction feels durable and provides a strong grip, even on bumpy rides. I was impressed with how well it keeps my phone in place on the handlebar without any shaking or slipping. The mount is easy to install, and the adjustable size accommodates various phone models. It has held up well during multiple rides, and I appreciate that it allows easy access to my phone for navigation. Definitely a great accessory for cyclists.
