RhinowalkBike Frame Bag with Magnetic Flap Waterproof Bicycle Top Tube Bag Bikepacking Cycling Tools Storage Bag for MTB Road Bike

Great item works well

Large enough for phone with cover plus stuff. Just a solid pice of kit, well attached.

Fits really well. Compartment really easy to open and close securely. But the cover in the bottom creases and swells upwards. It could do with some better suited material in the bottom cover.

Good quality, easy to install and very easy access on the move, a bit expensive though

Excellent quality bag easy to fit and secure the magnet lock is much better than a zip bag would recommend

The media could not be loaded. If you're after a top tube bag, then look no further. This is an absolutely top piece of kit.I was sceptical that it could fit on my e-bike, a Cube, but it fits like a dream thanks to the front velcro mounting strap and this clever underneath fixing method. What you do is pull the cord from the dial til it unhooks, then pull out enough to wrap under your crossbar, hook it on to the other side and dial the loose cord back in to tighten it up. I've not explained that very well, but it's a great intuitive design.The bag itself is nice and form, it's waterproof, the open and close tab works a dream, no zips to fumble about with.I ordered it in orange and it looks amazing.I couldn't be any happier with this bag.

Everything is good other than the internal method of storage. There are no compartments, or dividers in the bag. The second you have anything in the bag it becomes challenging to put a phone in.

The is not a budget case at £36 (Jul '24) and is a bit pricey for an unbranded amazon buy, effetcing value a little.However, this is a really nice top tube bag, that is well thought out.The lid covers down the sides so that rain wont get in and the material is full waterproof. The closure buckle is very easy to open on the move, yet is also very secure when shut.. Th bag is semi-rigid enough to stand without anything in it, so when partly loaded it wont flop.There is a nice velcro strap to secure to the steerer, and then a 'Boa' style rachet for under the frame. This is my main concern, that the thin boa style plastic covered wires could damage the paint if tiughtened enough to stop it moving, because there is no rubber protector or anything to go under them. But a bit of old inner tube will solve this and aid grip.Inside the back is another velcro strap - its really good, and this does have a rubber protector to sit under where the plastic buckle is, so when tightened that does not damage paint etc - probably the best designed velcro strap I have seen. This is designed to swap for the colour coded on fitted to the bag if you need longer one for securing to the steerer - but its a handy strap if you dont.Note that there are no internal compartments, which I think gives more flexibility for packing that having to fit things into set internal pouches, and this is a biggish sleek top tube bag, so will take plenty snack bars and gels or the like, but is wider than the steerer is ultra aero is your thing.I am really pleased with how well its made and the design is great - the only downsides being the boa system and thus the price.They should drop the boa thing for a normal strap, and reduce the price a fair bit as a result to have an absolute winner.
