[MENTION=476931]Glober[/MENTION]- Try again carefully following directions from the owners manual. That said, you won't find any codes for re-setting speed limit. If 17mph is the limit for the UK then that's your max without hacking (or finding a helpful dealer in France!) Not sure if fiddling with wheel size works.

This thread from Electric Bike Review forum has lots of discussion on both speed limits and codes. The thread is several years old so some of the numbers may be outdated...
