Hi all... Sorry if this has been covered elsewhere buy... I am the proud owner of a new Haibike with the latest Bosch drive system. When I asked the dealer about fitting the dongle to increase the speed of the bike, he warned that if fitted my warranty would be void. Although this seems reasonable and indeed I wouldn't want to lose my warranty, I wonder how so many people seem to go ahead with the mod. I suppose my question is, if I fitted this unit and then removed it in the event of a problem, would there be evidence that one had been in place. The latest dongle seems to need the wires splicing. Once this was done it couldn't be hidden. Any thoughts please..

Do a search on the forum. They've been discussed before a couple of times, and someone's got one.
Yes, he will. If you ever take the bike to be serviced or repaired the Bosch diagnostics will pick up the use of the dongle and your warranty will be invalid.
How do you arrive at that conclusion?
Is the Bosch software written to pick up pulses arriving at half or 3rd frequency and report this.
It would have to be pretty clever to do that.
I don't know, I didn't write the diagnostics software. However apart from that, using a dongle (or even a dingle) that makes the ebike illegal is the buyer's responsibility and they need to be aware that the bike warranty is immediately invalid, that any accident they are involved in will put them at risk of legal action and might also set back the cause for everyone trying to promote and legislate for electric bikes in the UK and EU. Unlikely, but possible.
