I finally succumbed to all the hype and picked up my first Velib the other day in Paris. I was trying to get from Bercy Village to Bastille and the friend I was with assured me that it would be much quicker than taking the Metro. As we wizzed through the streets of the 12th arrondissement I thought it was great, fast and efficient.
We zoomed past Gare de Lyon and arrived in Bastille in no time at all. Then we hit a snag. You have to deposit your Velib at a Velib station and furthermore if you're on the Velib for more than half an hour you have to pay. We rolled up and down the street looking for the parking spot finally we found one but it was full. We carried on riding but couldn't find another one eventually after about 20 minutes we managed to park our bikes.
So in the end due to parking problems it took far longer than the Paris Metro and I had to pay a fee for passing the half our mark (admittedly only 1 Euro) and I got wet because it was raining.
On the plus side it was fun and I didn't have to take the smelly Metro which, believe me, is a definite plus.
