I am challenging myself to ride year round. Gear isn't an issue..have that covered. I'm worried more about the bike. I rode in today (high 20's) and when I went out again about 4 hours later my battery had definetly lost some juice and it's fairly new. I have a Yuasa tender and where I work we have a warehouse that I can slip the bike into. Mainly this got me thinking....is there some kind of chart as to how much battery efficiancy you lose per hour as your bike sits outside in certain temps?
I realize upper twenties isn't THAT cold. I'm thinking more about a couple months from now when we hit single digits or lower.
Also, can you use a tender too much (such as plugging in every night)?
