Your weight, not the bike's. And what was your weight prior to commuting compared to your weight now?
I started commuting (4 mile one way) at the end of this June at 160lb. Now at 150lb. I've been an avid weekend hiker for the past decade, going usually around 10-12miles per hike and often 1-2 thousand feet elevation gain per hike, and my weight hadn't changed. I guess commuting 5-6x/week just burns more calories or boosts my metabolism more. I'm quite surprised. Well, with the weight loss I can add more accessories.
