docomo Bike Share Safety Initiatives

Relocation and maintenance of bicycles

  • To provide a comfortable travel experience,
    we rearrange the placement of bicycles
    to the cycle port and maintain the bicycles.

Quick detection of vehicles that are experiencing problems

  • We have the ability for customers to report problems
    with their bicycles themselves.
    This allows for faster problem detection
    and maintenance response.

How do cycle ports keep you safe?

  • In order to maintain the safety of the cycle ports,
    we have set a limit on the number of bicycles
    that can be parked at some of the cycle ports.
    We ask for the understanding and
    cooperation of our customers who use these bike ports,
    as this is an important mechanism for maintaining
    the landscape and ensuring the safety of our customers
    and the residents of the city.

Mobility development in response to customer feedback

  • docomo Bikeshare is constantly developing and
    updating its bicycles and attachments (keys).
    Based on regular customer interviews
    and feedback from our customers,
    we will continue to make improvements
    to ensure that all users can use our service safely.

Distribute safety awareness content

  • When riding a bicycle, the way you ride
    and the clothes you wear can greatly affect your safety.

    In addition to raising awareness of the essential
    knowledge of traffic manners and rules,
    we also provide detailed information
    on the dangers of riding a bicycle, such as slipping
    after rain or getting caught in a coat,
    through our app and website.

In some cases, the following safety measures have been implemented by docomo Bike Share in addition to the above.

-Automatically subscribed to bicycle insurance

-Freeze accounts of users who threaten safety
