If you're looking to get off the strip and enjoy the beautiful scenery, this is a must. The electric bikes make it easy for all fitness levels because you determine how much assistance you want. (Low level for good workout and high level for zero energy output)
Allison owns the company and is the guide. She is actually one of the few people from Vegas so she really knows the area. She was so knowledgeable about the history of the canyon, the flora, and the fauna. She is also just one of the sweetest guides ever.
For $89 you can't beat this. It includes hotel pickup and drop off. She even dropped us off downtown at a random taco restaurant (see my review for Tacos El Gordo) and told us stories about her family's unique experiences in Vegas.
There is a reason this tour is top on trip advisor. It's great!
