500 Smartphone Holder

I originally bought the BTwin 500 smartphone holder for a previous Samsung S7 phone and it fit perfectly, However, now that I have upgraded to the Galaxy Note 9, the insert is a tad too small, snug at best, and difficult to get out. Despite all that, I have lived with it and the actual holder is very secure. You attach it to the bike stem with the thick velcro fastening, then a further secure fastener fastened opposite way, over the large velcro to hold it all in place. The see-through case allows you to use the phone too and keeps any small drops of rain away. I still highly recommend this product, even bought another one for my son.

Take a moment

I read the reviews prior to purchase and was a little concerned to hear tales of the holder falling and a phone being damaged, but given the balance of comments overall I decided to go ahead. Please note there are two securing Velcro straps, when both are used my case and phone are rock solid. I'm very happy with this product but it takes a few moments to put in on securely.

Nice phone holder

The downside is it is hard to retrieve the phone. A sling that able to help pull up the phone will be helpful to take the phone out. Also it is a bit overpriced. Mind to reduce the price a bit.

Keeps falling off

Worked fine at first but then started falling off. Phone has hit the road multiple times.

Hello. Thank you for the review. Can I double check please that you have used the second small security strap that comes with the holder? You wrap the big strap around the frame or stem and then secure it with the smaller stronger strap. I hope this helps.

dropped off the bike, phone destroyed

Initially, I was very happy with the product until one day the velcro decided to give in without any sign of wear and tear and the holder dropped off my bike at a busy crossing and fell under my rear wheel - my IPhone 7 got completely damaged and I needed to get a new one. The velcro material used is of poor quality although initially it seems quite strong, it doesn't resist the pressure it is under when you strap on the holder to your bike.

Thank you for taking the time to give us feedback regarding the phone holder. I'm sorry to read that it came away from your bike. I will forward this on to the team in charge of this item at b'Twin. In the meantime, please contact our customer loyalty team on 0207.064.3000 regarding your telephone.

Hold all my calls!

It seems great so far, especially considering the price.

Working only when new

After several months of use (3 - 4 rides weekly) velcro fastening doesn't stay firm on stem and when it started raining during my ride last week - holder fell off twice during my ride (and I have noticed only because I was listening to the music via bluetooth and lost connection). This is another Decathlon Cycling product that has a very poor velcro quality. I am very disappointed as other Decathlon products are excellent.

I'm sorry to read that the hook and loop fastening stopped working. If the item is faulty, please return it to us for a refund or an exchange.

Has limitations

Fits well on riverside 500 stem, doesn’t wobble even on very bumpy tracks. Agree that with iPhone 7 it’s tight so home button doesn’t work. This is fine so long as you’re set up on the app you need before putting into the sleeve and attaching to bike. Overall, it did the job but improvements could be made.

Very useful. Check if it works well with your stem

Used on a 4-days-long touring trip. What went well: phone was securely mounted, touch input worked well, phone holder took some light rain without getting wet inside. What went less well: to take phone out of holder I had take undo the top flap and the strap that attaches holder to stem, which made it impractical to use the same phone to take pictures. The handlebar stem in that particular bike has a steep angle up, which made it difficult to read the map on the phone. It worked very well with other bikes, though. Veredict: very useful and good value, but check that the handlebar stem in your bike is mostly flat and be aware that it may be impractical to use the same phone for navigation and taking photos if using this phone holder.
