Judges' comments are outlined below:
Judge 1: This is an interesting proposal. I think the motivation for why cities would want this technology needs to be a bit clearer. I would imagine use of e-bikes would increase the use of bike transport, reducing reliance on other modes.
A common architecture for wireless charging of e-bikes is clearly an interesting proposition. Nevertheless, there is a chicken and egg problem as the wireless charger system needs to be widely adopted to have an impact and e-bike manufacturers (which are very diffuse) would need to adopt it potentially increasing the bike's cost for limited incremental benefit to the user. Not having personal experience with e-bikes, I always use conventional ones, I cannot vouch for the benefits and attraction of them to non-bike, vehicle users. While I would like to see the scenarios mentioned above in driving users to e-bikes instead of EVs, I think they are very different propositions and quite unlikely.
This is an interesting proposal, which could have a significant impact. Why haven't chargers been standardized already? What would it take to convince e-bike producers to participate in standardizing?
I agree with the authors that technologies which have the potential to increase the use of bikes (including ebikes) have the potential to create significant climate benefits! As such, I believe that wireless charging for bikes would certainly boost adoption rates. Unfortunately, the authors do not discuss the cost (first-order estimates) of the on-board unit and the charging station which would provide some more insights into the economic feasibility of the technology. However, I agree that a standardized charging solution would greatly benefit future use of ebikes and would thereby create substantial climate benefits.
The judges and fellows thank you for submitting this proposal.
The judges felt the proposal had high potential and was interesting.
A few suggestions could help refine and improve the proposal:
- elaborate on the business model - that is, explain who would pay for the chargers and the electricity
- explain the feasibility given the widespread implementation of (mechanical) bikeshare programs around the world
- build on the potential challenges and solutions that may exist.
- consider including an estimate of the CO2 reduction based on numbers presented in the current proposal

The novelty of the product has been explained.
The business model has been explained, with a rundown on the components.
The feasibility of the product implementation has been explained with respect to the increasing use of private e-bikes and the design focus to integrate the wireless charging solution with present day bike and e-bike rental solutions. In addition there is a energy audit that compares bikes and e-bikes. Furthermore, the cost issues that arise from rental systems has been explained and the need for alternative peer-to-peer sharing solutions.
An estimate of the CO2 reduction has been included. However, the link to the IPCC report is not functional. As this solution is not focused on a complete replacement of motorized vehicles, a percentage adaptation of the impact has been factored-in. As the main focus is on urban transport, the impact assessment requires a different data set. The description includes an alternative CO2 emission calculation that provides a brief summary.
