Why the KWIGGLE is so superior

For decades, inventors have been trying to develop especially small folding bikes. Why? Because if it were possible to design a bicycle that everyone could easily carry around - that would even fit in a bag - then a whole new mobility would be created that would make people's everyday lives easier.

But most ideas failed because they didn't really work, rode poorly, were unstable, or were still larger than other folding bikes on the market.

After more than ten years of development, the Kwiggle has made the impossible possible. With its hand luggage format, it has succeeded in making the leap to a compactness that is far superior to that of all other folding bikes.

This page shows you what we mean:

Kwiggle in action...

max.       55 cm
      just         9. 5 kg               

up to           40 km/h

WHY WE SELL DIRECTLY TO YOU

To achieve a low folding bike volume and weight, it takes sophisticated frame shapes and high material quality. And that has its price.

Thus, 10 kg light folding bikes with less than 100 l folding volume cost more than 2,500 euros. Since we sell directly to you without intermediaries, we save the dealer margins and can offer the Kwiggle significantly cheaper. In addition, we produce quasi just-in-time and save the expensive warehousing and logistics. You as a customer benefit and get much more quality and compactness at a lower price. And that with our 35 suppliers even MADE in GERMANY.

To Ride a superior folding bike


For us, the best innovation of the Kwiggle is:

The fantastic upright movement on this folding bike.

After thousands of miles, we can confidently say:

Riding a Kwiggle is physiologically superior to riding a "normal" bicycle.

THE FRAME

We only use high-strength stainless steel and 7000-series aluminum for the frame of the Kwiggle. 

  • The stainless steel steering tube and high-quality silver-brazed stainless steel joints bring springy comfort and ensures long-term stability.
  • All moving parts of the precision folding joints are equipped with extremely high quality wear protection. 
    This ensures a robust, exact closing joint, and with only one fold. This is unique and patented.
  • The lower frame parts have tab-like weld seams for the best possible stress distribution, manufactured with industrial robots in consistently outstanding MIG quality.
  • The rear frame section is particularly elegant and light and constructed as a single swingarm.
  • The fork is made from only one piece. This makes it light and strong at the same time.
  • We use sealed heavy duty 1.5 inch industrial angular contact ball bearings as the steering head bearings.

THE RIMS

In a special manufacturing process, the Kwiggle rims are manufactured from a single piece of wrought aluminum alloy, unique in the world, with outstanding properties:

  • light and rigid at the same time
  • wear-resistant even after many thousands of kilometers
  • highly corrosion resistant
  • highest running accuracy
  • polished noble look

This precision and robustness allows smooth running even at high speeds of 60 km/h (37 mph).

THE DRIVE

The Kwiggle's patented drivetrain brings the 12-inch wheels up to road bike speed at normal riding cadence.

The very robust mini derailleur reliably switches the 3 pinions with 7, 8 and 10 teeth. The pinion geometry allows a smooth shift change. The sprockets and the chain are made of the best materials that the bicycle market has to offer: high-strength stainless steel with outstanding wear resistance. This ensures many thousands of kilometers of running performance of chain and sprockets.

For maintenance, we recommend the oil and grease-free chain lubricant "DryFluids". High ceramic content provides a pleasant pedaling feel and significantly less dirt.

          THE CRANK UNIT

          • Miche Team CPT
          • Crank length 170 mm
          • 5-arm, bolt circle 110mm
          • 1 chainring with 46 Z
          • with integrated chain guard, 7075-T6 aluminum
          The Crank unit fulfills two important tasks. It has a particularly small Q-factor so that the feet can be as close together as possible. This is much more comfortable for riding while standing. In addition,  the Miche Team CPT is one of the lightest representatives of the square aluminum cranks.

          Chain wheel and chain guard are made of one piece, which results in a very noble look.

          THE SPEEDDRIVE

          • Schlumpf-Speeddrive, the most robust, smooth running and sealed.
          • Transmission 1 : 1 and 1 : 1,65
          • Easy shifting without cable mit Shift strips at the crank
          • Crank length 170 mm
          • integrated chainring with chain guard and 34 T, 7075-T6 Aluminium
          The Schlumpf speed drive turns a 3-speed drivetrain into a 6-speed drivetrain and is considered to be the most robust 2-speed bottom bracket gear system on the market. The gear ratio is identical to a 2-speed front sprocket with 34 and 56 teeth. This gives the Kwiggle 6 gears with 3.1 - 7.2 m per crank revolution, the typical values for 28-inch city bikes. You shift with your heel: right for the heavy gears, left for the light ones.  
          In the summer of 2023, we took over the production of gearboxes from Haberstock Mobility. In October 2024, the further improved Speeddrive 2.0 went into series production.

          THE TROLLEY WHEELS


          In trolley mode, the Kwiggle is easy to pull. Just like a trolley suitcase.

          The trolley wheels are made extra large for this purpose, so that pulling of the folded Kwiggle is easy and pleasant everywhere, even on uneven terrain.

          THE BRAKES

          The side-pull brake is the lightest and most space-saving brake there is. That's why we chose to use them.

          Because every millimeter and every gram counts.

          We have equipped the front brake with a brake force limiter, which prevents falling forward even when braking hard in the heat of the moment.



          THE FRONTLIGHT

          The IXON CORE 50 model from Busch and Müller combines detailed driveway illumination at 50 lux with high compactness. The IXON is a battery powered front light of high quality. It can be simply removed for charging and then connected to a USB charger.

          We mount the IXON just 40 cm above the ground in order to make the ground structure (edges, bumps) visible. The detection of cracks and bumps  on dark roads is therefore no problem. It also has an excellent light output.


          THE REAR LIGHT

          With the CatEye NanoG, we found a lightweight battery-powered rear light. The light simply clicks into the mount. To charge, simply remove it and plug it into a USB socket.

                 

                Kwiggle Pedals

                THE PEDALS


                MKS XP-EZY with reflectors, only 330g in total.
                Perfect functioning plug-in principle.
                Quality Made in Japan.

                We use plug-in pedals. This makes the folding size of the Kwiggle 2 cm narrower and has therefore reaches hand luggage size..

                The pedal is very easy to remove with one hand and is significantly more robust than any folding pedal.
