Quads
I've started this thread before but a new look is always good.
Does anyone know anything about quads? Before my accident they seemed interesting to me. Now I'm thinking that a quad may be the only way to go for the stability that it offers. The "Mountain Quad" is no longer in production but it carried a price tag of close to $8k. I can't see spending that kind of money on a pedal powered vehicle that doesn't have a body and an assisting motor. Their web site is still up, www.crank-it.com even though they are not making or selling any at this point. I read in VeloVision (great magazine from the UK) about a new quad ATB that is being made in France. It is also going to be pretty pricy at around 3-4K Euros. The Rhoades Car has been in production for quite a while but they don't sell a product that serious riders would be interested in (I think). I would love to ride one. I have no need for speed so the weight isn't going to bother me until I hit a good hill. I worry that I wouldn't be able to get something so heavy up a big hill. On the other hand I'm planning to stick to rail trails which are gently graded so the hill thing might not be an issue. Does anyone know of any interesting quads? Jeff |

Jeff I had some medicine take out one of my balance things in my ear. I'm building a delta trike for stability. Would a quad really be needed? Don |

Going up hills, if speed truly is not an issue, is not an issue on trikes and quads until they start rolling backwards. With no minimum speed to maintain balance, you can creep up as slow as you wish. Not /quite/: traction can be a problem with some designs when it gets really steep. But that would be seriously steep!

Jeff Try this website. http://www.bhsi.org/fourwhel.htm Going up hills, if speed truly is not an issue, is not an issue on trikes and quads until they start rolling backwards. With no minimum speed to maintain balance, you can creep up as slow as you wish. Generally, the reverse is the problem, especially upright quads and trikes (and especially the old style racing trikes that looked like modified diamond frame bikes). You can't lean except with a few trikes and you don't corner the same way at all, especially at speed. In my racing days I took a Carleton trike up to about 25 mph in a parking lot and then took it over the curb. It was either that or fall down. You corner using body weight and it is a bit scary above 20 on an open course. My understanding, BTW, is that anything under 50 pounds is a light quad, considering all the extra hardware in the transmission system and steering, plus the extra wheelset. Curtis L.
