SENQIFolding Bike Stem Quick-Release Aluminum Alloy Adjustable Stem Without Teeth BSZ002 25.428.6460mm

This SENQI (BSZ002) is as close as you can get to a factory fit bike stem replacement for an old Dahon Curve D3. It was super-easy to install for me as a novice bike repair dad and folding bike newbie.Before I go on about how happy I am about the results and benefits of this third-party replacement part, I must emphasize that THE BSZ002's HANDLEBAR FOLDS TO THE OPPOSITE SIDE (see photo) of the bike than the original bike stem. After the bike is initially folded, the SENQI (after it's properly released) folds down to the front wheel side instead of the crank side of the big. THIS IS ABSOLUTELY NOT A DEALBREAKER FOR ME! it only adds less than few inches to the width. It's barely noticeable to me, fits into a generic bike bag, and I'm "good to go" for bus rides, BART, and Amtrak.The SENQI BSZ002 is about a third of the price than an OEM stem (if you can even find one), and you don't have to talk to "that bike store guy" that's going to try to sell you a new 'folder with an electric motor for 2k! It feels just as sturdy and lightweight as the original aluminum set with nearly the same extension and feel. The folding clamp system is larger (and better in my opinion), and the plastic safety latch is totally different (not quite as good as the original), otherwise it's almost an exact match (see photo). I was even able to swap out the thumb clamps for the handlebars and stem extension with my throwback vintage set that came with the bike!

Good product.Couple of pit falls:1. Verify your handle bar diameter is 25.4.2. Purchase a set of spacers to make up the differences in fork tube height.

Perfect if you need your handlebars to fold down. Very easy to install.

Had to replace my Dahon stem in the middle of a 400 mile trip and this did the trick. I actually think this linkage mechanism for the folding action is stronger and more secure than the original! Only downside is the backup safety latch is kind of crap - just a little plastic tab on a ring that doesn’t fit well into a hole on the latch. It works, just not very well.

Fits my Oyama CX-E8D 2! Note, the bike stem will now fold outwards instead of inwards, but that's exactly what I wanted so it worked out for me. But do keep in mind the bike was not designed to fold in this way, so the two wheels have a tendency to split and open up if you try to move it while it's folded. I attached a little rope with a carabiner to keep the wheels locked together when it's folded (see photo). I will say the OEM bike stem has a better locking mechanism (it's one hand to open & lock and much easier to open) and there's a set screw to make sure the handle bar is pointed straight. This one does not have the set screw, so you just have to make sure you really tight down the bolt. This bike stem is also height adjustable (compared to the OEM handle bar), which allows me to sit more upright while riding.

I don't like this stem. I've bought other versions that are more sturdy and better quality for the same price. It's a little on the janky side. Wouldn't buy again and would not recommend to my friends
