How to use Leaflet Directions API with routeType = bicycle

Hi there,

i´m using the leaflet plugin directions API and want to generate routings for bike. I tried it this way:

dir.route({
locations: [
{ latLng: { lat: #{reportBean.coworker.lat_home}, lng: #{reportBean.coworker.lon_home} }},
{ latLng: { lat: #{reportBean.coworker.lat_department}7, lng: #{reportBean.coworker.lon_department} }}
],
options: { routeType: ['bicycle'] }
});

But it´s apparently the wrong syntax to apply the routeType parameter. Has anybody used it successfully? 

Thanks in advance
