Hi,
Also just moved to Basel to join my gf and am into cycling.
Here's a couple of routes I did recently, would be happy to do some rides if you are interested send me a PM.
Once you get out of Basel/Bale/Baal and the traffic

and the trams

it's quite good

I'm more into road biking at the moment due to a dodgy back but have a couple of mtb routes.
Welcome to Swiss
