I've for sure mountain biked before and it was no problem, just wondering about how it is in Alaska. They don't really provide good descriptions of the trails that will be taken. I am less worried about getting injured, just don't know if its really that much trail riding or just a mix. They also say the bike has electric power to it so it seems like something I would be okay with. Just can't find any reviews on this specific excursion online and I would like more details.
