Shared bike parking – advantages of a hybrid model

Most shared-bike systems currently operate on either a docking station-based or dockless model, with both options presenting challenges for cities. Station-based systems require greater upfront infrastructure investment, while dockless systems can lead to street clutter and require redistribution. A new study looks into the advantages of a hybrid approach.
A study conducted by York University, Toronto, in conjunction with micromobility operator Lyft Urban Solutions (LUS), has found that shared mobility does not need to be a binary choice between docked or dockless, and that an optimised hybrid scenario can provide the best of both worlds.
In a hybrid system, a rider can unlock a bike from a docking station near public transport stops, then park it in a designated out-of-docking-station zone near their destination. Such a system is designed to enable four trip types that docked or dockless systems alone cannot support: station-to-station, zone-to-zone, station-to-zone, and zone-to-station.
The hybrid approach is already being taken in San Francisco and Madrid, and the York University/LUS study has simulated various expansion scenarios across different cities to examine the effects on ridership, and infrastructure requirements. The simulation used a mix of publicly accessible open-source data, AI, machine learning and location data.
The simulation results
Hamburg, Germany, was selected as the initial simulation city for the study, thanks to its position as a large, expansive city with good potential for a hybrid model. The study’s aim was to address Hamburg’s areas which are currently underserved by the existing bike share system, while maximising utilisation, and providing strong links with the public transport network.
Four scenarios were modelled – the existing system (Scenario A), and three expansion models, which introduce a similar scale of new vehicles, under different configurations:
- Scenario B: a docking station-only approach, with 20 docking stations added near public transit in high-activity corridors.
- Scenario C: a hybrid approach, with 10 docking stations added at high-density transit hubs, and 10 dockless parking zones in the surrounding periphery.
- Scenario D: a reverse-hybrid approach, with 10 dockless parking zones added in high-density city-centre areas, and 10 docking stations added in the lower-density periphery.
Scenarios B and C both boosted annual ridership by 5-6% compared to Scenario A, increasing it from 1.22 million trips to 1.3 and 1.29 million trips respectively.
The capital expenditure required to see these ridership gains also needs to be considered. Scenario C, with only half of the new docking stations of Scenario B, was shown to achieve 99% of the ridership benefits of Scenario B, but with 50% of the upfront outlay.
Scenario D saw a fall in estimated ridership to 970,000 annual trips (20.2%), while still representing a high implementation cost (+110% capital expenditure) compared to Scenario C.
Caroline Samponaro, Head of External Affairs at LUS, said, “A hybrid model combining station-based and out-of-station parking can deliver the best results in terms of system performance.
“But the critical nuance is that placement matters as much as model type: station-based infrastructure belongs in high-demand, transit-connected locations; out-of-station parking zones work better in lower-density areas.”
The simulations were then applied to five other global cities – Paris, New York city, London, Copenhagen and Montreal. The hybrid model was consistently shown to capture the greatest share of potential ridership.
Fleet electrification
With cities tending to transition to electric shared bike fleets, the inclusion of docking stations in hybrid models has its advantages.
“Electrification will accelerate the shift toward station-based infrastructure,” Samponaro says. “As e-bike fleets grow, in-dock charging becomes less of a differentiator and more of an operational necessity. Every bike trip that ends out of station results in a bike that may need a manual battery swap. When a charging station exists in the most popular parking locations, the shared e-bike fleet charges while not in use, improving e-bike uptime and reducing operational cost and complexity.”
