Was travelling for a while and just saw your comment here
Thanks for the headsup, cleaned it up.
The "promo" was that they dropped 1000 bikes in various locations across Switzerland approx 5.30am on Thursday two weeks ago. Whoever found them first got to keep them, or exchange them for a 500 CHF off voucher on an ebike from Bau and Hobby.
I'm still holding on to the voucher (not really having any use for it) - anyone interested in it, feel free to message me (or write here, in case my inbox gets full again
), otherwise will put it on tutti.ch in some days..
