Miele's range in quality from entry level to top of the line. I have never read any detailed description of the company other than snippits from this forum. I believe form member T-mar to possess perhaps the most information on the company in his database (brain) for bike company history. My coworker has Miele he repainted which to mee appears to be from the 1970s and built with campagnolo drop-outs and may also have italian threading so I suspect it is a columbus machine. Some of their bikes were outsourced to Italian manufacturers it would seem and some Japanese. Some may have been built in Canada to. Is there a tubing decal on the seat tube? Are the drop-outs marked? These would point to the country of origin and the quality. As for the model... I don't think that is too important but pictures would allow us to discern whether it is entry level, high end, racing or sport geometry. Currently I have one miele bike in my stable. A 1986 Kuwahara built MTB made from ishiwata MTB tubing. It's all oversized and lugged and I use it as a town/basket bike.
