My hot girlfriend and I bought e-bikes last Spring. They're like the fountain of youth. Especially great if you're riding with your lady. e-bikes are the great equalizer for women. No waiting for her to catch up. No whining. Just right there with you stride, for stride the whole way.
They're great for discovering a new city/town. We do a lot of weekend getaways, and bring the bikes with us. Des Moines, Green Bay, Milwaukee, Red Wing, Baraboo, etc. We also rented e-bikes in Chapel Hill & Boulder last year. You can zip around and see everything in the open air like on a regular bike, but can cover so much more ground.
The rails to trails thing is amazing. What a fantastic way to repurpose old railroad tracks, into fun, useful bike trails. We did Red Wing to Cannon Falls a few weeks ago. Stopped in Cannon Falls for a drink, before heading back to Reed Wing. 50 miles round trip in a few hours. Last weekend we did the Fox River Trail from Green Bay along the river, about 50 miles round trip. Stopped a a winery along the way. Tomorrow we'll be riding the Gandy Dancer trail from St Croix Falls to Danbury, and back. We'll probably have a beer at a couple townie bars along the way. Just a really nice way to get out in the good weather, and enjoy nature.
We also use them A LOT here in the metro. Start at Minnehaha Falls, down the river to the Stone Arch bridge. Up the street to the 1029 for a lobster roll. Back through downtown to the Mpls Sculpture Garden, along Lake of the Isles, & Cedar Lake, to Calhoun, Harriett, stop at the rose gardens, the zen gardens, the bird sanctuary, stop at the Malt Shop for a boozy shake, along Minnehaha Parkway, to Lake Nokomis, and end up back at Minnehaha Falls, without feeling the least bit tired, or breaking a sweat Same with St Paul. Start by the Lake St bridge, ride down the river/Warner Road past downtown Stp, loop back through Mounds Park (amazing views), hit the St Paul Brewing Co on Payne Ave. back through DT, up West 7th, Mancini's for an Old Fashioned.
So much fun.
