SPAREHAND Bike Frame Adapter - QSP-610 Telescopic Powder Coated Bicycle Carrier - Crossbar Adapter for Bike Rack, Adjusts from 22" to 32" - Universal Fit for Various Bike Sizes & Models - Red Ends

I purchased a new Trek Fuel 8 and needed an adaptor because the location of the rear shock interfered with my bike carrier. I was in a hurry to buy so I purchased a Lund from the bike shop. I am a mechanical engineer and immediately saw several design flaws which could have allowed the bike to come loose. The next day I went to another bike shop where I found a Thule adaptor. Again, design flaws that could result in release, only this thing actually opened with a little force (whoa!). After reviewing this Sparehand on Amazon I purchased it and was very pleased. The design of the hooks opens outward and not up or down and not at the center of the hook radius but near the neck of the adaptor instead. As a result, the weight of the bike rests on the hook radius which is solid steel and should keep it from falling if it somehow opens by accident. The button releases are actually recessed into the frame of the adaptor and not standing out, so that your bike carrier straps cannot accidentally engage and allow the hook to open. You can tell there was more thought behind this design than the two other adaptors I purchased. Be mindful of the maximum expandable length and hook dimensions others have commented about as that could be an issue for some bikes. I do like the retractable feature on this item, it makes it easy to handle when taking on an off the bike. Overall a sturdy product with a good design. I liked it so much I purchased a second one for another bike and returned the two originals to the bike shops.... As a word of caution, this is not a sub for your bike frame. Whenever you use any of these adaptors you should always secure the frame to your carrier with additional straps. I would recommend this to anyone.

It is a necessity for the bike rack I purchased. It works well and is easy to install and remove. I'm pleased with it. I just used it to haul an 80 pound step through e-bike from Tulsa to NW Arkansas and it worked great.

I bought this to use with a women's Schwinn touring bike. The bike frame is small, but I am not sure of the exact size (I am 5'1"). This bar, at first glance, was too long. Yes, it fit around the seat post and the head tube, but there was extra room and I was worried that it would be a problem in terms of sliding when the car was moving. Using a Saris Bones bike rack we attached my bike to the rack using this bar. Once the bike was in place, it was stable. There was no movement, scratching of the paint, or any other negative outcome. The only reason I am giving it a 4 star review is that this is the first time we have used it. It looks like it is a well made product, it is easy to use, and it was delivered post-haste. Don't be totally dissuaded when you read negative reviews about these bars for women's bikes. Even if it had been a little big and not stable I could have come up with an innovation to take up the slack. I fully recommend this product and hope you are happy with it! On the photos you can see the black bar on the bike, the clamp around the seat post and the clamp around the head tube. Happy biking!

This product does exactly what it is supposed to. It is well built and easy to use. It works very well with 2 women's bikes that we have that have very large down tubes. Bikes that were previously difficult to mount on a bike rack can now be mounted in just a few minutes. The jaw release / closure mechanism works easily and closes securely. Take 5 seconds to attaché the "Sparehand Bike Frame Adaptor" and then proceed to mount bike on your bike rack with the same method you would use to mount a man's bike.I was a little hesitant on the price, but now I am happy to have made the purchase. I will probably buy a second one for another bike. One note of caution. Not that I had a problem, but it would be wise to make sure both the seat (and seat post) and the handlebars (and handlebar post) are tightened securely. The weight of the bike suspends from these two points when the bike is mounted to a bike rack using the "Sparehand Bike Frame Adaptor."

After checking all the bike frame adaptors, we went ahead and purchased this one. It's works perfectly. We used it with a Hollywood Expedition Rack for 2 bikes. We have a Felt women's beach cruiser and the adaptor fit without problem between the seat post and handlebars. If there was any issue with the adaptor it would have been that on one side we had to put not the plain bar but the actual pin connector part into the bike rack holder. This never became an issue, we just made sure the pin part faced up. On our bike, we did have to use a strong strap to hold and shorten the distance between the front top frame and the adaptor. The front of our women beach cruiser was hanging below the back bumper, so by tieing the adaptor and front part of the frame together we were able to lift the bike up to just above the bottom of the bumper. This was not the fault of the adaptor but because of our oddly shape women beach cruiser.

I needed three grab bars (2 kids bikes, and 1 woman's bike). I bought three different brands, figuring I'd either hit a home run on all three, or at the very least, find the best bar. All three (Hollywood Racks, Swagman Bar Adapter Deluxe, Stoneman Sports QSP-610 Sparehand Adjustable Bike Bar Adapter) have performed well so far. My only complaint is the Hollywood doesn't rotate like the other two. For my kid's bikes, I tried to put the bar from the seat post to the top bar of the handlebar, as suggested by others. However, the Hollywood doesn't rotate to allow this to happen. No worries, though, since I was able to take it from the seat post to the traditional position on the handlebar post. My kids bikes are 20", so that may help others as they guage how it might work on their kid's bikes. I'm guessing the need to go from the post to the top bar is for REALLY little bikes, which I don't think the Hollywood bar would work, but it will work for 20" and above for sure.
