if you are going up a steep hill make sure you are going fast enough to make it all the way up. i did not... and got hurt pretty bad. it cost me 1500 bucks to get it fixed, bummer. please be carefull when riding up hills they can hurt you bad. lucky for me i had my helmet on, it did get broken as well. could have been much worse. the good news is that once the hoda rolled end over end about 6 times it started right back up. tried to ride it back to the truck but my back rim was bent badly so i had to ride back on the wifes bike.
