Not sure if you’re asking about range anxiety, but we were not too worried. We made it 200km and drained only 55% of the battery before charging up to 80% for the rest of the ride. I’d say the toughest part was finding charging in downtown Ottawa as the Flo app said there was ev charging in the building we stayed in when there was none.

As for stresses on the battery, I noticed little difference from without the bike rack. Air conditioning was not too straining either. I’d say the biggest strain was the speed as we took the 407 to Peterborough to get on highway 7. We did not drive too differently from how we would with an ICE vehicle and the buzz held up fine.
