Review on 🚴 ROCKBROS Waterproof Bike Bag - Top Tube Phone Holder Pouch for Mountain Bicycles - Front Frame Touch Screen Cell Phone Holder Compatible with iPhone X, 8 Plus 7 by Brian Vasquez

Very nice. The reviews I've read say it's changing. nope I ran two straps under the diagonal tube (bike frame) and the front loop around the head tube. Absolutely cozy. Much more space than in a small bag under the seat. The most interesting thing is the phone holder. This is a fixed velcro over the bag. The zippers on the side pockets do not interfere. The clear plastic cover allows me to control my phone while it's in the case. It's hard to see in bright sunlight, but what phone can't? I've read that phones can overheat. Here (in central Texas) it was 104 degrees and no problem. I left the zipper open about 2 inches to allow it to breathe. Music and Bluetooth are on all the time when I drive. I'm using an iPhone X. Some reviews say the driver's knees hit the pocket. no I am 6 feet. 0, rides a Specialized MTB, size XL, 29" tires. At the closest, my knees are over 3" apart. The bag is roomier than it looks, well made and is amazing value. I have been cycling for over 45 years and I would recommend this bag.
