Hiring a Velobleu bike could be great BUT you need to be aware that EACH PERSON must have a mobile phone & a credit card on them in order to hire a bike. Tough luck if you have 3 kids, you won't be able to hire one for them as each person can only book out one bike!!
The concept is very good - lots of bike racks in the city and you can pick up and drop off a bike as you pleae. As four adults, we needed to make 2 telephone calls (supposedly free but probably not as all calls on our mobiles are at international rates) to register our details and because we only had 3 mobile phones between the four of us, we could not hire 4 bikes. VERY UNFRIENDLY FOR TOURISTS!!
I telephoned the complaints line of the company only to be told "Yes we know this is a problem" !!
We would have loved to have cycled this lovely city, so I encourage anyone else who has had this problem to let the Velobleu people to let know that they need to improve this situation. Their website is www.velobleu.org
