Another clueless American ebiker question about Europeon law. Is the article's bike legal? Individual can self build a high energy battery with parts and tools from online sellers putting an alibaba balance charger in parallel with the original BMS, no external testing review or inspection. And the authorities/insurance don't care about this customization vs the factory model they presumably inspected before certifying.

Alternatively if you software configure a motor controller so that it sends motor current from a throttle instead of a torque sensor in the pedals, you'll be busted?
