Trek bikes are cool - I’ve had a great time streamlining and coordinating the efficiency of my trek FX 2 ebike - lightweight enough to still ride manually, like an acoustic bike, but when you combine the battery assist, low, medium even high and how to coordinate your ride with your gearing and cadence I’ve been able to travel on my trek bike up to 75 to 80 km with one charge. I will admit, I rarely use the high assist setting, don’t really need it
