exclusively developed brakes
This worries me somewhat. On one hand, when the objective is a sub 10 kg ebike, all options should be available, even if that means having to custom-build components, and brakes would be no exception. On the other hand, there are some parts on bikes which have been refined by existing engineering efforts for racing bikes, which includes brakes, although racing did remove the incentive for lighter bikes when the bikes became structurally unsound.
Even still, it’s hard for me to imagine how much mass can be shaved off of brake handles, calipers, and discs, such that they make the savings worthwhile. The flowery language on their website does not adequately explain exact what their brake design improves upon, other than being “engineered in Switzerland” and “exceptional reliability and performance”.
Still, 10 kg is quite the achievement unto itself. Though the €12k price tag means this won’t be an everyday city bike for the masses.
I assume the weight is saved with lightweight motor and battery, from the look of it the brake system shave not much weight but i assume they want something new with better stopping power or integrating that with the motor? Caliper looks very different and i don’t see any chance of it being retrofit with common part without being crafty by adding a bracket.
Yeah, I’m reeeealllly hesitant to buy anything that has proprietary parts: Repairability is more important to me than saving a few ounces.
