Frame and fork
-
Frame
6061 T6 aluminium frame that's lightweight, dynamic and sturdy. The single-arm frame design at the back makes the bike much narrower when folded. It's only 35 cm wide. That's 20% more compact than the 20" folding bikes in our range.
Suspension
-
Fork
Single-arm, 6061-T6 aluminium frame for less weight and more strength. The single-arm fork design makes the bike incredibly narrow when folded. In fact, it's only 35 cm wide. That's 20% more compact than our 20" folding bikes. We've also used topology optimisation to develop a more "open" frame. This technology ensures that we use just the right amount of material while retaining the necessary rigidity.
Drivetrain
-
Cassette
9 speeds Gearing: 11 / 28 teeth - 11 teeth on the smallest cog. For riding faster. - 28 teeth: on the biggest cog. You won't have to push the pedals too hard.
-
Crankset
52t aluminium chainring with 170 mm cranks. Folding pedals so that the bike is even more compact when folded.
Brakes
-
Brakes
This bike has V-brakes with aluminium levers and calipers for powerful, progressive braking. Recommendation:your brakes will gradually wear out over time. How quickly they wear out will depend on how much you ride and how you ride. If your brakes become too soft, and your levers end up touching the grips when you squeeze them, we recommend adjusting your brakes yourself or getting a workshop to do this for you.
Wheels and tires
-
Rims
16 inches. Single-walled, machined rims. Reinforced single-sided hubs with sealed ball bearings (the same technology that we use on our road bikes).

Saddle
When you're cycling: The seamless foam saddle keeps you comfortable. When you're walking / on public transport: The ergonomic saddle under the saddle has two functions. - It makes the bike easier to carry when completely folded. The saddle swivels to face backwards to keep the bike evenly balanced when you're carrying it. - You can use the handle to hold the bike and push it along when folded. Simply leave the seat post raised.
-
Seatpost
- Made from aluminium, with a diameter of 34.9 mm. - Marked so that you instantly know exactly where to set it to each time for the most efficient ride. - Automatically rotates as you lower it. It's guided by 1 brass screw and 1 groove. The saddle swivels to face backwards to keep the bike evenly balanced when you're carrying it. - Turns into a stand when you lower it fully so that the bike remains stable once folded.
