1. Recovery figures come from the factory road-test logs, not from the spec sheet. Those logs show 0.6 to 1.0 A into the pack, which is roughly 20 to 33 W. The spec sheet states a 45 W rated output; we have not observed it and do not quote it as achievable. Real recovery depends on speed, cadence, gradient and rider weight.
2. The 50 km figure is measured: five full-charge road rides at maximum assist averaged 48 km, ranging from 41 km on hills to 53 km on gentle roads. The 100 km figure is the factory theoretical maximum at low assist. We publish both, and lead with the measured one.
3. The 25 kg max load figure is under confirmation with the factory; it is believed to describe the rear rack rather than rider weight. Confirmed wording will be published here.
4. Assist cuts off at 25 km/h. Markets with a 24 km/h statutory limit require a firmware map; ask us before ordering.
