rewelding aluminium frame - Mercedes bike
I have a Mercedes bike and the top tube has cracked just near the weld to
the headstock. Despite the bike being just two years old and having done on ly 2200km, Mercedes are undecided whether to repair this under guaranty. They have not ruled out a warranty repair completely, but it is is currently being deliberated at a higher level. In the meantime I am thinking it may be easier just to get the frame rewelded. Is this a complete waste of time? Might it be worth getting fillets welded in to support the new weld? |

Given that aluminium frames don't last forever anyway, is rewelding not a viable option? I only do 2000km or so per year on this particular bike, so if it lasts a year between rewelding it will be worthwhile. |

You need to know the type of alloy, give it the proper heat treat cycle, source the same alloy if you want to add strengthening plates etc etc You could just weld and not heat treat it but I wouldn't ride such a frame - you'd never know when it was going to fail on you Accept it - if they won't replace it, scrap it and get a new frame.

Given that aluminium frames don't last forever Aluminium frames may not last forever, but Cannondales (for example) are guranteed for the lifetime of the original purchasor, so someone at Cannondale is pretty confident they're good for at least fifty years; which is as near 'forever' as I'm interested in. anyway, is rewelding not a viable option?

Strange that they make a car that last for ever, but their bike frame falls apart within 2 years. My Mercedes car is two years old to and is also a pile of junk. But that's enough about cars... Incidentally the Mercedes bike is built by a specialist bike manufacturer in Germany. It is just labelled and marketed by Mercedes. The name of the manufacturer is something like "Berton" (the Mercedes people did not know exactly) but I can't find anything like that googling. Any hints? If I can trace the manufacturer, I suspect they will be more reasonable than Mercedes about replacing the frame. If not I'll just have to try welding the frame up. The reason I want to keep the bike if poss is that it folds (albeit rather clumsily) and is rather useful. |

The reason I want to keep the bike if poss is that it folds (albeit rather clumsily) and is rather useful. I thought it was an AMP - http://www.amp-research.com/oem/foldingbike.htm Did you buy the bike or did it come with the car. It would be worth checking with eg Citizens Advice Bureau or Office of Fair Trading about your rights. Mercedes cars come with a three year warranty so it may be that that covers the bike if they were supplied together. You may also have some statutory rights - e.g they were not fit for purpose - against them or the Finance/credit card company if they were involved. Know your rights and then tackle Mercedes. Do not rely on them to know or volunteer your rights. As an aside, when I was buying a Merc earlier this year I got a quote from a dealer and asked the local dealer if he would match it. He complained about other dealers undercutting their prices, wanted to know who had given the quote and said he was going to complain to Mercedes about the other dealer. I politely asked if they were trying to operate retail price maintenance. He went very quiet and I took my business elsewhere. Tony |

Strange that they make a car that last for ever, but their bike frame falls apart within 2 years. The thing is that the 'Mercedes' bike wasn't made by Mercedes. It was made by an industrial design company called AMP Research, who had no previous experiecne of designing or building bicycles. The most important aspect of the design brief, according to AMP's self-congratulatory write up, was that 'it symbolized the car marker's new, more youthful brand image.' Great way to build a bike. -- (Simon Brooke) http://www.jasmine.org.uk/~simon/ ;; Women are from Venus. Men are from Mars. Lusers are from Uranus. |
