Took a tour this last weekend with my family which included 30's, 40's, and folks in their 60's. With the electronic assist, this is an activity for all fitness levels. We made a few stops, where our guide talked about the area and its history. We rode about 15-16 miles in total, spanning 2 hours (first 30 or so is orientation) and just made me want to spend more time in town.
This has inspired me to seek out similar activities when traveling to other cities!
We did a sister's weekend and wanted to see more than just the shops in town. We loved the tour, getting some of the history of the town from our guide and seeing Leavenworth from a different angle. It wasn't difficult and the e-bikes were fun to ride. We hadn't been on them before, but we all got the hang of it easily.
Our guide was knowledgeable, interesting to listen to and answered all our questions. We ran into the owner while we were on the ride and talked for a bit. Nice business and they delivered as promised.
