Betuy Waterproof Rear Seat Bag, 7L Bike Saddle Bag with Reflective Tape, Mountain Road MTB Bicycle Outdoor Sport Pannier Trunk Bag Bicycle Accessories Shoulder Bag with Water Bottle Pouch（Black）

This was a bit of a leap of faith as I didn't know if I'd get everything I carry into this bag. At present I've got three different types of carry bags (handlebar, crossbar, backpack) for everything I need - repair tubes, tyre removal tools, rain jacket etc but I needn't have worried as the whole lot fits nicely into this bag.It secures nicely to my new luggage pannier and the bag itself just seems to ooze quality. The zips are a joy to behold as they just glide shut and it certainly seems to be waterproof as everything was nice and dry the first time I encountered rain.

The luggage rack on my e-bike (Furo X) measures 28cm by 14cm. This bag fits the the rack perfectly and is very easy to secure with it's tough velcro straps. The straps are as illustrated, reaching easily around the rack and holding the bag firmly in place. It appears to be well made, all zips and stitching in good order. The main bag will hold sandwich box, large water bottle, map, book and waterproof. The side pockets will be handy too. I haven't tested for waterproofing yet, but will take a small rucksack cover for extra protection in the event of a downpour.

Have used this bag on the back of my mountain bike quite a few times now. Have been caught in some heavy downpours. Items in main compartment have all stayed nice and dry and so have the side pockets. Plenty of room and I am able to keep my repair kit and spare tyre in the side pockets. Haven't used the back pocket for my water bottle as I have a bottle rack on my bike but a friend has bought the same bag and she does. Easy to fit inside. Easy to put on and take off my cycle rack. I would highly recommend this bag.

I bought a bike with a rack on the back. I needed a bag to hold basic puncture/repair kit and other bits for a journey (food). I looked around in bike shops and prices were £40 or more. This Betuy bag meets my needs at a good price. It has zip pockets for repair kit etc. Velcro holds it firmly to the rack.

Disappointed with this. It is the correct size and well made and good value for money but it is extremely difficult to attach the the back rack as the velcro straps are too short. The result is that the bag hangs off the side of the rack and is essentially stopped from falling off completely by the shoulder strap which I have wrapped around the seat several times. Shame. I am going to try to get advice on replacing the straps but I guess I should have sent it back!

Brilliant fitted well and plenty of space without being to big ....only criticism that I have is the bottle space could be a bit bigger apart from that loved it ....but that's just a personal thing.... good value and will be buying another one for my partners bike .

Bought this for my bike, it holds quite a lot and goes on the bike really well. Plenty of compartments for things

The bag itself has great features but there’s no way it would fasten on my bike rack. The fixtures are in the wrong place and just not functional. Returned
