Isn't that a wooden frame bicycle? No, the Razz-Fazz has a carbon fiber reinforced polymer (CFRP) frame. However, both wood and CFRP are polymer composite materials. I think the Razz-Fazz is too low to the ground for touring. I know it was meant for racing, so that's that, but it looks like it's the oppsite of a diamond frame racer where you're looking at the ground, the Razz will have you trying to look over the mechanics on the front of the bike. |

To me, the position one sits on a recumbent would be the primary position one would use in designing this thing called the "bicycle". A recumbentbicycleis the most comfortable position, but not the most efficient. An upright is more efficient, especially at climbing hills.. Thats just your opinion. Sure it might be the common opinion, but we havent seen all recumbent designs yet, or all riding technics. Cruzbike has some ideas that also use the arms to help drive leg power into the wheels. The arm and leg power together has often been tried but it's really a dead end. *Fact is the human body can use its entire quota or aerobic power in the legs alone, so aside from unsustainable sprints adding arms in is a red herring that just makes the bike more difficult to design, build and ride. However, Ed's supposition falls foul of the IHPVA record sheet, where given free reign to design what they please to go as fast (i.e., as efficiently) as possible, the lion's share of the records are set on recumbents. *Still, Ed's never been one to let facts get in the way of his pronouncements. No one needs any records to KNOW that recumbents can't climb hills worth a damn. Since they can't, they are overall slower than uprights since the world is full of hills. Even slight grades slow recumbents down a lot compared to uprights. Regards, Ed Dolan the Great - Minnesota aka Saint Edward the Great - Order of the Perpetual Sorrows - Minnesota God, I used to get asked the old "but I didn't think recumbents climbed hills?" question a lot, normally whilst overtaking a normal bike on a hill. Recumbent are fast down hill a bit faster on the flat and climb if you have the technique right as you have something to push against. Just comes down to skill and fitness.

The "something to push against" being the seatback and "the technique" being to spin fast enough in the proper low-enough gear to avoid blowing out ones knees... Hill climbing is easier on my Volae than my Tour Easy and easier on the Tour Easy than on my BikeE. I cannot make direct comparison of ease vs. an upright bike,-- I haven't ridden an upright bike on a hill in more than a decade. However, I'm able to keep up with my upright friends on most hills. There are certainly upright riders I couldn't keep up with on hills or no hills. On a self-supported mountainous bike tour with my son,-- him on his upright touring bike and me on my Tour Easy,-- I climbed at the same rate as he did. Neither of us were fast. I was carrying a bit more weight on the bike and a bit more weight on me and about 30 more years on me... It's probably generally true that many/most recumbent riders don't go fast up hills. It's (mostly) not about the bike. It's also generally true that many/most upright riders (general population) don't go fast up hills either. It's not about the bike. Jon |

Recumbent are fast down hill a bit faster on the flat and climb if you have the technique right as you have something to push against. Just comes down to skill and fitness. You make the same mistake that many otherwise well informed recumbent cyclists make. The fact is that some recumbent cyclists get very good at climbing hills, but they are working at it ever so much harder than an upright cyclist. There is really just no comparison. Being able to push against the seat is no substitute for the upright position on a bike. Recumbents can be faster downhill than an upright because of a slight aerodynamic advantage. I think they are about equal on the flats, but they are clearly woefully inferior at climbing. It is why you will never see any recumbents in the mountains.

Wrong, oh obstreperous one! It is all about the bike and not anything else. Of course, hills slow everyone down no matter the bike. But hills will slow you down much more on a recumbent than they will on an upright. Thus spake Zarathustra.
