Parts found in a manufacturer catalog show their brand, model and key numbers, and the steps show how precisely they are identified: brand, series, model, or the exact product. The info button has every detail and the text the manufacturer published.
B'Twin Alur18 Alu6061 frame approved by the UCI. Aluminium is an ideal choice for obtaining an excellent propulsion-to-comfort ratio. The variable thickness tubes considerably reduce the weight. The cables are built into the frame. Frame weight: 1400g in size M. B'Twin carbon fork and aluminium pivot The combined use of carbon and aluminium: an ideal combination to obtain homogeneous behaviour with the frame. Fork weight: 550g.
Rider-height ranges are not published for these sizes.
Understanding sizes and measurements
Height ranges are reported by the manufacturer. A matching range is a starting point, not a guarantee of fit. Your proportions and bike setup also matter.
Reach is the horizontal distance from the bottom bracket to the top of the head tube; stack is the vertical distance.
Positive values mean more reach or stack than the reference size; zero means the same measurement. Missing values are not estimated.
Size
Geometry not published
The manufacturer lists these sizes without frame measurements, so there is no drawing or geometry table.

These speeds describe the gearing at the selected cadence, not how fast you can ride.
Calculated from published gear-inch values and their wheel-size assumptions.
These gearing values describe the bicycle, not a selected frame size.
A 100% range means one ratio; 500% means the highest ratio is five times the lowest.
For e-bikes, motor assistance cutoff is not represented.
Gear-inch range
Lower gear-inch values travel less distance per pedal revolution; higher values travel farther.
