Once a month should be ok. 1/2 hr to an hour of spirited riding (not idling in traffic) is enough.
I deleted my previous post 'cause Tee Tee covered it very well. I do ride about once a week through winter, and you can usually find a nice break in the weather every week or so. Dec through Jan may be the worst months, but it hasn't been that cold the last couple of years. Forecasts for this winter are warmer and drier than usual.Thanks guys for the input!
TeeTee what's ur opinion on the frequency?
If I say I am planning to ride it at least once a week, is it a practical plan? I've been living here a long time but I never pay attention to the weather until I started riding this year... how's Vancouver like through December and January?
