I’m all for the tandem bike, but it’s difficult to share the experience since one person is inevitably staring at the other’s rear. Enter the Dual Seat Adult Tricycles. Each seat includes its own independent set of pedals and gears, you’ll just have to settle on sharing the strearing. Clearly they’re targeting this thing at the older crowd and hence the uber expensive model ($2,499) which includes an Electric Power Assist mode that runs off an onboard battery and provides up to a 10 mile range. The cheaper version costs $1,699.
