I have been cycling for years and my husband doesn't have as much speed or interest that I do. This is a reverse from the norm, but the idea is the same: maybe a tandem can help us share the sport. I am 8 inches shorter and 70 pounds lighter. Trying it, I trusted his piloting. But I did not enjoy looking forward at his broad back. From what little I have read about semi-recumbent tandems, there wasn't anything bad written in the forums. But yet it seems to be a scarce bird on the road or in print. Does anyone have knowledge as to why it has not gotten popular or why not to buy one (if one can be found)?
