I do a fair bit of cycling (Trek 2200) and my wife wants to start cycling. We believe a tandem is our best bet. We went to Matthews bikes in Indianapolis recently and looked at the T2000 and the Santana Arriva. We could purchase the T2000 for about $3200 and the Arriva for $1000 more. We will probably bike about 50 to 60 miles a week. Suggestions are appreciated.
