Velib is trailblazer, but not disruptive innovation.
Velib's "smart-dock" approach is way too expensive to be sustainable long term. It is also inflexible.
The advantage of SoBi's (and viaCycle's) "smart-bike" approach is a fraction of the cost of the older "smart-dock" approach. The "smart-bike" approach is also much more flexible, which in turn will reduce certain operating expenses (aka opex).
However, the "smart-lock" approach of NextBike may give clues to the future (it hasnt been perfected yet).
Velib, Barclays, Bixi are all Palm Pilots....SoBi, viaCycle and NextBike are all Androids and iPhones....its just a matter of time.
