Anyone who has ever been on a tour knows that your guide really can "make or break" your tour experience. My husband and I had a blast with Brandon learning about all the desert plants, animals and the surrounding area. It was exciting to learn the electric bikes. Brandon's enthusiasm was plain to see and made the tour that much more fun. Any tips? If you have to travel over 30 minutes to get to the tour starting point, make sure to stop to go to the bathroom BEFORE arriving! There are no bathrooms where you take off from. Any negatives? The only tiny issue for me personally is that I am short and very light. The bikes are for "normal" size people even with the seat all the way down :-( I was perfectly able to ride the bike, and still had loads of fun...but felt as if I really needed to be a bit more cautious with the throttle (than the others) at certain points. Since my feet just barely touched the ground, I couldn't just put them down quickly for stabilization.... which made it harder for me to totally "let loose" at certain points. That being said, I would still do it again!
