Mine is on a 2002 version. There is limited battery space in the frame, but it works well. There is always something better! Do a lot of reading. Define the gotta have it features, check the wallet, and go.
Stiff frame and rear suspension. good brakes, strong rear wheel are just a few of the things I went looking for. I wanted a very well cared for, upper end bike at a good price. You will have enough things to work on without having to rebuild the basic bike.
