Bicycle access options for a week-long stay in Paris I'm going to be in Paris this month for about a week for some conference. My accommodation is about ~15 min away by bicycle from where the conference in held, and for most of the days (say 4 or 5) I'll just be traveling there in the morning and going back in the evening.

Now, I don't have a bike that I'm bringing with me, but I would like to use a bike in Paris. I can...


Rent one
Borrow one
Use the municipal bike share which I've just noticed - Velib


Intuitively I would think the public bike share would be my go-to option. But I'd like to ask the more experienced: Is that really the best options? Would it be cheaper than the other two options? Are the velib stands ubiquitous enough to not add too much walking to my route? Is it customary to use something else?

either rent or borrow I suppose. My question is: In broad strokes, what are the options for renting or borrowing a bike for a week-long stay? Is that common at all in Paris? Should I try to do this through certain websites? Local bike shop? Some other way? Or - perhaps 

Also or use some public bike system if one exists
Velib makes the most sense for you. The use case you outlined is exactly what bike shares were designed for: short point to point trips where you don't necessarily expect or need to take the exact same bike back with you. 

Check out the prices: 



So, you'd take a &lt; 30 minute one way ride in the morning for 1 Euro, ditch the bike for the day, then take a (probably different) bike home for 1 Euro. 2 Euros round trip. That's probably cheaper than taking transit, and I challenge you to find a bike rental for &lt; 15 Euros daily. Even if you can, as noted in the comments above, you then have the additional worry of theft/ vandalism, and hassle of having to return it to a bike rental place when you're done. 

If you want to do a longer bike ride or full day of bike exploration before or after your conference, you could do a one-day proper bike rental for that.
