DownloadTECHNICAL INFORMATIONS
Colour
The imperfections in the brown frame colour (hues, shiny wear) are not quality defects but instead, the result of our design choice to use brushed aluminium, tinted varnish. Your bike will therefore look like no other!
Frame
6061 T6 aluminium frame—lightweight, dynamic and sturdy.
The very easy side-fold system with a lever helps to save up space: at home, at the office, in the boot of a car or in a camper... you'll forget your bike is even there. There is a mechanism to quickly lock the frame and stem so that you can keep the bike folded and transport it easily.
Frame with a stand for better stability once folded.
Fork
Aluminium 6061 T6 fork for a lower weight.
Drivetrain
The Shimano Sora 9-speed drive train gives your bike increased precision and reliability when changing gears. The wide range of speeds lets you pedal hard on flats and effortlessly get back up to speed after stopping.
Distance travelled per turn of the crank: - smallest development: 2.90m per turn of the pedals, 28 teeth
- largest development: 7.2 m per turn of the pedals, 11 teeth
Brakes
Aluminium V-brake and callipers guarantee effective and progressive braking.
Handlebar / stem / steering
Semi-raised aluminium handlebars with a 60 mm rise for adjusting the steering position to suit your body shape and improve handling.
Handlebar width: 560mm.
Fixed aluminium stem with quick-release lock for greater stiffness compared to a height-adjustable stem.
Distance from saddle to handlebar: 540 mm. Bottom bracket to saddle distance: 480 mm to 780 mm.
Ergonomic grips.
Saddle/Seat post
The comfortable memory foam saddle is made without seams to prevent water getting in when riding in the rain.
Anti-theft, anti-rotation aluminium seat post 31.6mm in diameter.
Wheels
20 inches, double-walled machined rims.
Tyres
Tyres with anti-puncture reinforcement and reflective strips for improved lateral visibility.
Size 20 x 1.75.
We've developed these tyres using Skinwall technology for lower weight and higher performance.
Crankset
The fold-up pedals reduce bulk when the bike is folded.
Once pedals are folded up and the stem folded down, the bike can be stored against a wall and takes up very little space (26 cm wide).
Aluminium cranks: 170mm.

Stand, mudguard with stays, double chainguard to prevent chain slipping and protect from dirt.
All colour variants include a rear derailleur guard.
