Hello , we had a blow out up front on our tandem and went down breaking my wife's clavicle and scapula . She spent the whole hot summer with her arm strapped to her body since there was really nothing holding up her arm. After summer break she returned to teaching only to trip, and while protecting her damaged side ,broke her other collarbone. We picked up one of those Bike E's so she could at least get out on a bike trail. good luck
