Perfect got it. That makes life easier for me.
I guess I'm not looking for fatties. Just need to figure out if I'm going with the R1U 700 or the new Radcity. uff. Tough call I guess
Regarding the tires that come on the 700, they're Schwalbe Super Moto-X 27.5x2.4" which are arguably one of the better tires available right now. They score high to very high on flat resistance, rolling resistance, and ride. They will be tough to beat no matter what they're mounted on. There are 5 bikes in our household, and after several years messing with a LOT of different tires, all use that make and model tire today.....
As mentioned, the 700 has some great specs and is a formidable competitor when considering the new 'City. The difference, as mentioned earlier, is about RAD's popularity. There's very little doubt they are on top of their game. Have a look at the freight on them. Last I saw, they were being delivered through local dealers, something no other consumer direct seller does....
Regarding front forks/suspensions. My experience has been you want one.

As far as spring vs. hydraulic, if you were to ride both on an identical course, I think if that course were paved, you would have a difficult choice picking which were which - assuming only that the spring tensions have been optimized for your size/weight/riding 'druthers. If this course were off road, it would be a whole different world, with the better front end taking a beating that you would NEVER simulate on a paved/hard packed surface. Suggest you ride the bike a bit as it comes, THEN make your call to replace the front end if you think it's necessary. -Al
