An e-bike that feels like a bicycle
A torque sensor reads how hard you push and scales a 250 W mid-drive to match, so the assistance arrives in proportion to your effort instead of arriving all at once. Carbon belt, sealed gear hub, removable battery, 19.2 kg all in. From €2994.
Solved, not sketched
Stack, reach, head angle, head-tube length, fork rake and bottom-bracket drop are not six independent choices: together they determine exactly one fork length. We solved that equation for all three sizes at once, which is why all three take the same 430 mm fork — one part number, one fatigue test, one spare.

Battery
Three capacities in one housing, all using 21700 cells from a single qualified supplier. Changing cell manufacturer means repeating UN 38.3 and IEC 62133-2 testing, so the cell is fixed in the technical file and only the configuration changes.
