Bought a Magnum Summit, and took the word of the dealer that "this bike can be ridden on any trail in Moab." Being an ametuar expert single track rider, I should have known better, but it was not my fault that the bike battery lost connection on the only two rides I took it on, and even after the mfg fixed it the first time, it still would not work on single track, since the battery connection came loose and it lost electricity both times I took it on single track. Crap bike, and the dealer charged me $500 restocking fee for a bike that NEVER worked. $500 for 2 rides, each ride the bike breaking. That's robbery, and a piece of (blank) bike.
