Get More Free Space: The widest part of a bike is the handlebars, and this folding bicycle stem cuts it in half by swiveling the bars parallel to the bike quickly and efficiently. Our bike stems are compatible with 1.25 handlebars for modern bikes and 1” for older bikes. Keep Your Bike Safe: There is no safe way to lock up a bike outdoors, but a house-trained bike can come inside at home or office, keeping it safe from theft and rust. Our road bike stem and MTB stem can do just that! Keep Your Bike Accessible: Slim down your bike with our bike handlebar stem and MTB bike stem to fit near entrances — alongside the car, in the hallway, etc. — where you are more likely to use it on the way out the door. Easy To Install: Our folding bike stem installs with a couple of standard hex wrenches. Just swap out your existing threadless road, flat, or mountain bike stem to start saving space. (Before ordering, know the diameter of your handlebar at the stem). Portable Adventure: Our rugged and versatile bike accessories are your go-to solution for convenient bicycle portability. Store or transport your bike with ease and embark on a next-level cycling adventure with us!
