WTwo groups of interested parties are not in a position to deal with the usual technical and legal arguments: the Sparbrötchen and the amateurs, as to whether it is worthwhile to modernize a self-propelled bicycle with an auxiliary electric drive. Some sting prices a little cheaper: even the most expensive renovation rates are lower than the cost price of a new pedelec, although barely. And for the Allesselbermacher, the homemade electric bike is just another adventure, just because it can be a little tricky, it's all the more exciting.
Of course, everything is very simple in advertising promises: conversion is a kid 's game and requires little more tools and experience than removing a panel. Anyone who disputes this point of view risks being subject to personal interest and excessive profit. Of course, who has the shop full of pedelecs from 2000 euros, who can not advise the purchase of a modification kit for 500 or 600 euros. And will not develop it on behalf of the customer. That's true, but it's not just financial reasons.
If the bike is really good and there is nothing technically opposed to the upgrade, you will always find it difficult to find a dealer or bike mechanic who expertly converts. More than a completely different commercial interest, this is due to the fact that the installer upgrade makes the manufacturer responsible, even if the bike and the new disc both come from third parties. The reseller who badembles is responsible not only for his correct work, but also for the conformity of the pedelec created by his work and put on the market by a whole set of standards and regulations, such as the new European guideline EN 15194.
A look at how to use a new electric bike that has been turned into a complete brochure with its compliance statements, documentation and – often just fun – hazard warnings indicates the cost that the dealer should make to be safe with a technically simple conversion. For the industry and each of its series, extensive mechanical, electrical and chemical testing has long been performed by well-paid service providers: a five-figure amount adds to other development costs depending on the type of service. construction.
This eliminates everything in the DIY absolutely legal. The case where someone converts his good old three-wheeled vehicle not only with a motor limited to 250 watts, but in the basement at home, by electronic tuning or with a motor thicker and more powerful than 39; a lightweight motorcycle clbad L1e was created, that he then banned from driving without type test and insurance registration plate moves, rest here. It is of course illegal.
The number of bicycle manufacturers who then electrify the wheels of their customers is very small. These include factories such as Velotraum in Weil der Stadt, Utopia in Saarbrücken or HP Velotechnik, a specialist in tricycles and tricycles at Kriftel. They offer different models with and without motorization. When retrofitting, which requires precise control of the individual wheel and the conversion allowed, there is practically a model variant, a pedelec exactly as you could buy it in the form of a complete wheel – at the appropriate price.
