The biking is really fun and getting funner...Part of it is, that there are many pedestrian underpasses and the ramps (for wheel chairs) are different every time - narrow, with lots of bends or corners AND they go up and down, so, with a bike with no gears it can be a bit challenging at times. I have a basket on the front and sometimes, after shopping, stiring gets even more interesting.
I found a store with Marin bikes in it - prices are higher or the same as in Marin for a Mt or road bike.
