The heat shield does all teh work, i must admit on those cold days the heat down my legs is nice And the wind takes care of the heat in the summer

My mrs has never complained about the heat on the cibbyy aaahhh ahhh, however she does look a tad out of place back there sat up on the pirch and shes ony 5'4. i think the "two's up' was a bit of an after thought on teh latest sprots bikes
