"The much-rumoured Bosch power update coming this summer can be taken as a sign that regulation truly is coming though. We hope the rumours really are true, and that riders with a Bosch CX Gen 5 motor will be able to uprate their bike’s power to around 100Nm of torque and 750W of peak power. If that’s the case, ask yourself, why has Bosch stopped exactly at 750W? Is it a lucky coincidence or does it know something about future legislation that the rest of us aren’t privy to? "
It's harmonisation. After many years of being out on a limb, the USA with its three EAPC classes has fallen into line with the EU practice that has become de facto the only world standard for assisted cycling:
Class 1 = Basis EU EAPC with no throttle.
Class 2 = As above with throttle, the equivalent of the 250LPM, meaning like a type approved EAPC, but only accepted as a motor vehicle in EU law.
Class 3 = Speed pedelec, the S class in the EU, a no throttle EAPC capable of assisting to 45kph / 28mph.
The USA still has two differences, 750 watts as the stated power limit for all three classes, instead of the EU's concealed similar permission via Continuous Rated Maximum Power, and 20mph assist limit in lieu of the EU's 25kph / 15.5mph.
37 0f the 50 States have fully accepted the new class law and the minority remainder have partially accepted it, so we largely now have only one international law for assisted cycles.
Which of course facilitates exporting, hence Bosch's interest, but won't please Donald Tariff Trump.
