There is one problem that probably every city cyclist faces: a steel horse takes up a lot of space in an apartment. But bicycles shouldn't take up so much space at all. These are fundamentally thin cars - only a few centimeters wide, if not for the spreading steering wheel (and, to a lesser extent, pedals).
Startup Revelo Thinstem is proposing to replace the existing stem on your bike with a custom one that will allow you to rotate the handlebars 90 degrees regardless of the front wheel. The cost of the mechanism is $ 70 - $ 90, depending on the size of the stem. Folding or detachable pedals are available as an option.
Thinstem is 90mm or 70mm long and supports 1 "and 1.25" handlebars. Installation on a regular bike takes only 5 minutes. The only tool you may need is a wrench. Once installed, Thinstem is operated with a simple lever. When the steering wheel is unlocked, it can be lifted up and rotated 90 degrees. Then the lever must be locked again.
Of course, not for everyone, Thinstem is the best solution. Nuances to keep in mind: If you have a basket on the handlebars, you won't win by turning it 90 degrees. You will also have to sacrifice some functionality if your bike has an unconventional adjustable bar. The steering wheel after manipulation can change the position of the hands and body when driving if it does not correspond to the previous setting.
But these are minor complaints. Thinstem aims to solve a common problem for cyclists and does it with a simple and reliable mechanism.
