A simple idea with huge benefits
Turn annoying handlebars out of the way in seconds
That height-adjustment cam lever under your bike seat? Suppose you had one just as strong under your handlebars? Then every time your handlebars became annoying, they could just pivot out of the way in seconds, with no tools:
And when you’re ready to roll, they auto center and tighten down for rugged riding.
One stem, more usable space
Make every bike easier to live with
Store A Whole Herd of Bikes
Have an N+1 problem in your garage? Here’s the solution, without pulling bikes down from the ceiling.
Have a bike for every member of the family, strewn across the entire garage? Not only will this give you more of your garage back, but each bike snaps into riding position instantly, getting you on that family bike ride faster.
Treat Your Bike Like It’s Special
Bikes brought inside last longer and are less prone to theft. And if your bike is flat, you can park it conveniently near the door, so you can just grab it on the way out. Use it more. Enjoy it more. Experience the
freedom of biking again.
Rider-tested for over six years
Trusted across road, mountain, e-bike, gravel, and cruiser setups
THINstem has been rider tested and highly rated through four successive versions on road bikes, mountain bikes, e-bikes, gravel bikes, and cruiser bikes.
Excellent product. Handlebars flip 90 degrees and no longer contact the rear window when on the bike carrier behind my fifth wheel.
I have three e-bikes in my van. THINstem makes it possible to pack all three within 29 inches of the wall. It’s great!
Where can I get it?
Word has gotten out. Due to growing demand, now including retailers, the first four versions of THINstem have completely sold out.
We had already designed a version 5, with 300 units planned for the end of October just when a lot of bikes are coming inside for the winter. But higher than expected purchases have created a gap before the next batch arrives.
