Can I get the same workout on the rover as my 2 wheeled trek 7.1 bike? I have wrist numbness issues after riding on my trek bike causing me to think the trike is a much better position ergonomically for me than the bike. I want to be able to keep up the level of workout. I'm also 6' 4" will the rover extend long enough for someone my size. I also weigh 290. Currently riding 8 - 12 miles on level concrete trails. A side trail approximately 2 - 3 miles is a large hill trail that I would like to continue to ride for the workout. Any recommendations?
