Joe I am not trying to veer off topic and was responding to the previous posters comment. Both the Airnimal and the Helix are 24" bikes. Yes the front wheel has to come off of mine. I keep hearing that is a deal breaker for commuters. As a commuter I am just trying to say that in day to day experience in an urban setting I have not found that to be the case. I am not trying to take away from the Helix which looks awesome, I'm just trying to point out that a folding time difference of maybe another 30 seconds really going to make that much of a difference? How many times in a day is the bike folded? Mine is twice a day. Is the average 4? That is a similar issue with bike weight. I keep hearing 25 pounds vs. 20 pounds is a no-go, but I am just sharing the experience that lugging a 20 (Airnimal) or 25 pound (dahon...closer to 27) bike up two flights of stairs at the train station exit feels about the same to me. To me the beefy frame/tires and rolling feature are what makes the Helix a better bike in an urban environment. When you have that in conjunction with a good fold and a decent weight then you have a better overall package. Just my opinion as an avid Helix thread reader
