Cost ceiling shapes choices

Session summary

Published

The room worked through how to double an e-bike's range (60 to 120 km) without breaking the weight ceiling (25 kg) or the cost ceiling (about 1100 EUR). An early instinct to simply double the battery was set aside once participants saw it would add roughly 5 kg and break both limits, and that premium cells plus a carbon frame would blow the cost. The conversation then reframed the problem: start from reducing energy consumption (a more efficient motor, aerodynamics, better tires) and work backward to the smallest battery actually needed. That inversion produced a concrete candidate configuration: efficiency and aero gains cut consumption by roughly 23 percent, so a 1.07 kWh premium pack (not 1.4), plus the efficient motor, aluminum frame, and aero upgrades, lands near 1170 EUR and around 23 kg.

Patterns

The group moved from rough intuition to a fixed numeric gap (the 46 km shortfall) and then closed it.

Open questions

Was regenerative braking, raised in the data, considered as an additional margin?

Notable directions

Treating the 46 km shortfall as a fixed engineering target to design against.

Possible next step

Ready for admin review

The group could run a single consolidated check that confirms whether the proposed configuration meets all three limits at once (verified 120 km range, total cost, and total weight) before taking the 70-EUR overrun to management.

Signal: Emerging signalCould become: No specific output yet

Why: Several participants converged on one concrete configuration and explicitly asked to verify all three constraints together, but the next step is an internal calculation rather than an external ask or new team.

This is a suggested direction based on the conversation, not an active campaign.
