And suddenly there was space.

No bolts to loosen: swivel the handlebar with a single motion.

 Trustindex verifies that the original source of the review is Google. Stairwells in Holland are often very narrow, which usually prevents you from storing your e-bike indoors. Thanks to this stem, I can now easily move my e-bike upstairs and around corners. It's a real game changer. The CNC-milled stem is very high quality and looks great on the bike.
