@iamsomewhere I'm a fair weather rider, so my board rarely gets wet except the occasional puddle. My Vega lasted 1500 miles and could've gone further, but I wanted to try a treaded tire, so I put on a FF 6.0 Hoosier and just love it! My board charges and rides like the day I bought it (well, except the much improved tire!).
Did I read that you are from the Czech Republic? Because I used to manage a group out there, so I was going to Brno 3 or 4 times a year for the last 5 years before I retired in January.
