Well the bike has nine gears and three of them I never use - even for the highest hill - they are redundant....I was maxing out on 23mph on the flat today and Intuiva up signal was pointing up 'asking for more gear'. I would love to give two or three upward gear changes. i'm not sure I would really go this far but 30 would be really interesting (if the motor has the capacity it seems like a waste to not use it if necersary). SW you say you are getting 35 I guess you have to pound the pedals aswell?...that is an incredible speed eitherway..!
