I tried the full 17 miles today. Unfortunately, the motor on my electric bike cut off on me. It would come back on after I turned the battery off and on but then cut off again after a few seconds. I think it was too hot -- 97 degrees! I normally ride earlier in the day or later at night, when it's only low 90's. I was about three miles from home when I finally called my husband to come help. The bike weighs and ton with the motor and batteries and only has seven speeds so even though I tried to keep riding without the motor, I was just too hot and tired. The hills are the reason I got the e-bike in the first place! I'll be getting a ride to work tomorrow until I know why the motor cut off.
