Review: Hard to beat on $11 for this KISS Tension Bar Adapter - Warehouse Deal - V. Good was excellent to me. Slightly damaged box, brand new adapter without a scratch on it, for just $11 (1/3 of the regular price). Notice that there are 2 different tension bar adapters by SportsRack; this is the Advantage Heininger version. Instructions were on the box - which to me weren't quite apparent to me, because the box itself was slightly damaged (hence Warehouse Deal) and desertcart put a lot of Warehouse Deal Inspection barcode stickers right on top of the instructions. Nevertheless, they're quite simple: 2 loops of different size on each side - 1 for the seat and 1 for handle bar (instructions would tell you which side to be positioned). Each loop has a piece of metal bar that opened in 1 direction by pressing a button "ball" (or locked by that same button ball). The tube itself could extend/contract but there's no locking mechanism to fix the length (hence my comment on KISS - because you don't need to lock it. Just think about this - the length between the handle bar and the bike seat couldn't be changed on a bike, so once you put the tube in between, the tube would always be "locked" in that length, until you remove it and put it on another bike. Yes, there's some leeway but that's only a couple of inches max. Besides, the extension itself actually has quite a bit of friction to it so it's not like free and lose extension. Now, there's 1 important part which I believed that those 1 star critical reviews didn't give this adapter some justice. Make sure that you position the adapter up/down correctly! Gravity always win, so if you position the bar with the bike handle/seat pressing against the opening mechanism (so the opening mechanism would be against gravity), neither metal piece could open naturally from vibration, and the weight of the bike would serve as the 2nd lock. But if you position it wrong, then gravity on the bike would put stress on the metal piece and potentially cause it to open up. This was probably think by an engineer, and probably not using an use-case for an everyday person. Great product nevertheless.
Review: Received on time - Worked great for folding ebike

## Questions & Answers

**Q: Does this tube fits a Specialized Shiv?**
A: It's an adjustable bar to go from the handle bars to the seat so you can place it on a transporting rack.

**Q: does this fit children's bikes 16" and 18" size?**
A: Yes but its not really needed unless its a girls bike as I was able to mount 12" & 14" to bike rack without one.

**Q: How many pounds can this adapter hold ?**
A: It can hold up to 30 lb standard bikes

**Q: Can one of sides rotate 90 degrees so it will connect from the seat post (horizonal) to the handbar (vertical)**
A: No. It’s a rigid 180 degree bar.

### ⭐⭐⭐⭐ bike extender
*by A***0 on July 19, 2014*

It is great for bikes that do not have the bar straight across. Harder to figure out ways for smaller bikes though. thought it should have been tighter around bikes. But great for the purpose it was trying to serve.
