I looked at the pictures and specs for the new Montesa 4Ride and compared them to the 4RT. After several weeks of cogitation, I decided to buy the 4RT and modify it slightly so I could enjoy it on trails here in central Colorado. So far (one trip down the driveway), I'm stickin' with the program.

Besides, there will be no 4Rides imported into the US in the near future (likely never), so I had to start with the 4RT anyway.
Just MHO.

I'm naming the project 'TrialsToTrails'.

Stay tuned...
