Wow, so much fun!!! I'm a huge fan of biking but my girlfriend hasn't gone biking in years so I was worried about the 16 mile round trip. During the tour we stoped 4 times for about 10-15 min. each so you don't spend all 3 hours on the bike. With the E-bikes it was a breeze, cruising with the self assist at about 10-15mph even up hill! It really gives you a chance to enjoy the views with still having that self accomplished feeling of having earned it. Definitely our favorite part of our trip to Leavenworth.
