Question: It seems that this fits certain bike racks better than others. Since I haven't purchased a rack yet, can anyone recommend a rack that fits perfectly?
Document: Fits on my rack perfectly (an old aluminum Jim Blackburn rack that I've had since the mid-1980s). Can hang it on the inside of the shopping cart at the grocery store, and then pulls off easily and mounts to my bike. Simple design that does the job perfectly.
Definitely recommend these for anyone using a bike to do shopping.
I purchased two rear detachable baskets for my urban bike with a rear rack. I love them because they are easy to take on and off. This allows me to store my bike on croweded bike racks and smaller places and also be able to transport items to and from work or local stores. I get lots of compliments on them, although they do look like dorm garbage cans, so when my mom was visiting she threw her trash in one of them!
rear racks that had the supports spaced such that the baskets wouldn't slide forward.FYI - I bought the Sunlite Alloy Rear Carrier for Bicycles (26") and this is not a good match for these baskets.On a final note though, I would rate these baskets with 6 stars (i.e. better than perfect) if I had a rear rack that kept the baskets away from my heels (and my feet are only average sized (11) for a male).
It's still holding up perfectly. Still recommend.
I'm in no way associated with the company, just a serious  biker who's found a quality product I'd recommend to others with the same needs.
It needs some type of locking vise mechanism, but I understand there are probably so many different types of racks that this may not have worked for it, so I am going to look into just getting an inexpensive clamp from a home improvement store so I can do without the bungee......not a real big deal, but would make taking off a bit quicker.I highly recommend this. I think we need more people on Bikes and less cars on the road.
I bought two of these for my Trek Allant bicycle and they fit perfectly on the back rack. They are easy on and off, have great carrying handles and expand my shopping capacity substantially and easily. I do a lot of my grocery shopping now on my bike. You just have to remember that with the baskets, you are a little wider.
I love the ease of hanging it on and off the rear rack - no straps, buckles, or clips to mess with. You just set it down and go, or pick it up and shop! I did not experience my heel hitting the basket while pedaling - it's perfectly positioned and very stable on the rack.I bought it for a trip, but now the basket has become a necessary accessory to my commuter bike. Cool baskets you'll love!
I ordered this on Amazon, but because they had to back order it at the time, ended up getting it at a local bike store. These baskets fit perfectly on my Bontrager BackRack. Sliding is not an issue with this rack as they fit in-between crossbars on the rack, thus they cannot slide. I got two baskets. I can use only one and not notice any issues with balance. For grocery shopping, I use two.
Answer: yes
