Review on ROTTO Bike Top Tube Bag: Secure Bicycle Phone Holder with Touchscreen Function and Rain Cover by Brandon Vox

A very useful product if you only want to ride your bike and don't want to take a lot with you. In contrast to other cell phone holders, the cell phone sits directly on top, which is securely protected by the touch screen. Other valuable items are placed under the storage bag. It also comes with a rain cover which is great. This is a universal model that fits "most" bikes. However, we have two bikes and this one doesn't quite match our "big folding bike" (Montagu) because the front strap gets caught in the front folding stem (where the derailleur is) and makes it difficult to turn. It works great with another impassable bike so I still recommend it.
