Boreen bimbler,
"They are crap on steep hills and rough ground..."
While I appreciate the comments in your post above, I do think that this comment should come with some specific details. What is your definition of 'rough ground'? A lot of 'rough ground' discomfort can be mitigated with different tires, lower tire pressures, and additional seat padding. And what is your definition of 'steep hills'? Many have in fact stated that they have few issues climbing except when tackling climbs in excess of 15 degree of elevation or in slick conditions.
I am not questioning your experiences just the fact that you as a new member, make very broad statements which could easily lead others new to and/or interested in Cruzbike to get the wrong idea. Again, I am not questioning your motive just your method.
The Cruzbike forum and its members are awesome and welcome every one but there is an expectation of mutual respect and consideration. I hope that your experience as a new forum member will be as wonderful as mine has been, over time. You won't find a kinder more helpful group of people anywhere. So ask questions you may be surprised.
And, welcome to the site!
