I've been commuting for about 8 years. It's been fun... but never more fun than it is now - I've done an ebike conversion to my commuter bike. I thought it would be cheating... it is... but guess what? I don't care! It only saves me a few minutes each way. It's pedal assist only and the assist cuts out at 20 mph. "Climbing" the hill on the way home is an absolute joy! I don't work quite as hard commuting, but I find myself challenging myself to keep the bike at the 20 mph limit or more. I still arrive with a bit of a sweat... and a BIG SMILE!
