don't sweat it. toshi's obsession with metrics is how he makes up for his lack of speed (as demonstrated by his continued use of shimano brakes and claims of not having issues with them) and helps him justify his ebike (to him at least)I don't have any concept of heart rates. I feel like my heart rate is pretty elevated riding moto or DH when I'm going hard. I want to see the graph showing constant pedal output over 200w with spikes into the 400s. Then I want to see the poor drivetrain that suffered under 600-1000w for most of a ride. Nah, actually I don't care. Arguing that ebikes are exercise is like saying motos are. Of course they are. You're riding aggressively and feel tired at the end. Doesn't mean you're the one propelling the bike though. I just accept ebikes for what they are, short travel lightweight motos with a 21mph governor and a weird throttle system. When I can get what is essentially a Surron (200mm travel, DH geometry, aftermarket twist throttle) that's half the weight and still has decent range cuz I can turn off the motor and pedal during the transfers I probably will. It'll replace Surron rides though (which replaced KTM rides), not MTB rides.
