My 13 year old daughter and I went out with Marek last week and had a great experience. Marek had talked with me before we met so he was ready to go when we arrived so all we had to do was adjust the fit of the bikes and helmets and go. Marek made it fun, customizing our ride to meet our fitness levels and mountain biking experience. He provided breaks to take pictures of the scenery and he took professional quality photos of us. We rode 13.5 miles and Marek and the fat bikes made it a unique experience that we highly recommend.
