c2g-engineering GmbH, the company behind the Schindelhauer Bikes brand, was established by four founders. The fact that two of them are mechanical engineers is an indication of how important in-house developments and collaborative projects with other developers are to us. It also shows that we are not afraid to design products ourselves that are not yet available on the market.
Our development and design skills are our pride and joy. Over the years, we have further expanded our know-how and strengthened our team.
Here is a selection of our in-house developments:
Schindelhauer - Belt Port
Unfortunately, physics is in the way, as the belt can’t be opened the same way as a chain. Our patented Schindelhauer belt port system (almost) completely hides the opening at the dropout and makes mounting the belt a breeze.
A form-fit, wavy wedge ensures a tight connection between the seat stay and the chain stay. The wedge can be inserted and removed like a piece of a puzzle. A continuous bolt locks the components into one rigid structure, making it appear as though there had never been an opening in the first place. Conventional seat stays are held together by various couplings and bolts, but our system is dedicated to the aesthetics of the hidden. Frame openings can’t be avoided, but in the case of a genuine Schindelhauer, you can’t spot them.
Slider belt tensioning system
“How do I remove the rear tyre if it goes flat?” customers often ask us. Here is our answer: The dropout of our bikes stands out from that of other manufacturers in that we intended to create a user-friendly solution that would fit seamlessly into our bike design. The slider belt tensioning dropouts featured on our geared bikes make replacement of the inner tube a walk in the park.
The rear wheel slides down gently when the axle nuts are loosened, making it easy to remove the belt and the wheel. The specific angle of the dropout ensures that the belt is tensioned to its default level during installation.
Crocodile belt tensioning system
We didn’t forget about our single-speed models and therefore strived to develop a mechanism that would be easy on the eyes and easy to use. Our patented Crocodile tensioning system facilitates the tensioning of the belt. Giving the sprocket a simple twist freely adjusts the axle, resulting in precise belt pre-tensioning. Turning the spring washer with a 17 mm spanner causes the axle to move back, pre-tensioning the belt in the process. The axle is fastened with a hex key.
Our single-speed and fixed-gear models feature the Crocodile tensioning system on both sides. All components of the Crocodile system are made of high-strength aluminium, which makes them both lightweight and durable.
In 2012 we developed the Urban Pedal, which is built to withstand the rigours of the daily commute. A flat profile and even contact patches ensure top traction. Some types of pedals leave marks in the leather soles of expensive shoes. To prevent this problem, we used non-slip, industry-grade grip tapes made by high-quality manufacturer 3M.
Weighing in at about only 300 g per pair, the pedals are also remarkably light. The hollow high-strength aluminium case and the cut-outs for the pedal straps are milled in a sophisticated CNC procedure. We chose a combination of sealed industrial bearing and plain bearing to make the Urban Pedals as flat and light as possible.
What’s more, the pedal and the crank form an elegant connection that practically goes unnoticed, as we skipped the usual fastening thread. The pedals are mounted on the end of the crank through the pedal spindle with a 6 mm hex bolt.
