From my observations, I can confirm this statement as far as possible.dominik hat geschrieben: ↑Mi 4. Mai 2022, 09:13For 100km/h you need about 7kW at the rear wheel
For 120Km/h you need 70% more power, which means >200A continous from the battery, bms and the controller.
And you need a higher KV which means less tourque or you need a higher Battery voltage to get more rpm.
The speed around 100 km/h is a pivotal one, because there the aerodynamic resistance really kicks in.
In fact, if you are riding in the slipstream behind a lorry, you don't even need the ~ 7kw to reach the 100 km/h, and yes: you can even run faster then (if the lorry does as well ).
You need to be aware of this phenomen, because if you think you can pass the lorry easily and leave the slipstream to overtake, you're in danger because your excess speed will drop drastically.
Btw.: yesterday, as I drove at the B45 (without any slipstream), I just reached the 100 km/h... and my coulomb-meter showed a current of 123 ampere and 76.5 volt battery voltage. so the power was just 9.4 kW.
