This paper reports on a review of the European literature about the impacts of having an electrically-assisted bike available to use, together with results from a trial in the UK city of Brighton, where 80 employees were loaned an electrically-assisted bike for a 6–8 week period. In the Brighton trial, three-quarters of those who were loaned an e-bike used them at least once a week. Across the sample as a whole, average usage was in the order of 15– 20 miles per week, and was accompanied by an overall reduction in car mileage of 20%. At the end of the trial, 38% participants expected to cycle more in the future, and at least 70% said that they would like to have an e-bike available for use in the future, and would cycle more if this was the case. This is consistent with the results of the European literature which shows that when e-bikes are made available, they get used; that a proportion of e-bike trips typically substitutes for car use; and that many people who take part in trials become interested in future e-bike use, or cycling more generally

The smart e‐bike monitoring system (SEMS) is a platform for the real‐time acquisition of usage data from electrically‐assisted bikes (also called pedelecs or e‐bikes). It is autonomous (runs off the bike battery), replicable (open source and open hardware), scalable (different fleet sizes) and modular (sensors can be added), so it can be used for further research and development. The system monitors location (global positioning system), rider control data (level of assistance) and other custom sensor input in real time. The SEMS data feeds an online interface for data analysis, for riders to view their own data and for sharing on social media. The basic system can be replicated by other researchers and can be extended with modules to explore various issues in e‐bike research. The source code and hardware design are publicly available, under the General Public License, for non‐commercial use. SEMS was implemented on 30 bikes and collected data during 10 months of real‐word trials in the UK. This study details the design and implementation of the hardware and software, discusses the system use and explores features for future design iterations. The SEMS turns singular e‐bikes into a networked fleet and is an example of the internet of things in the cycling context.

Little is currently known about the possible benefits of using networked technology to enhance ensemble performance. This study explored whether the introduction of specially devised technology – networked tablets using traditional music notation – to a primary school orchestra would enhance the experience of ensemble music. Particular emphasis was placed on how the technology could help children to overcome practical problems associated with ensemble playing for early-stage musicians (e.g., keeping in sync with other players), thereby leading to better engagement with the music and ultimately greater enjoyment. Findings from a thematic analysis of responses from a focus group with eight young orchestra players aged 9–11 years and from an interview with the orchestra conductor, together with indications from the statistical analysis of 28 orchestra participants’ questionnaire responses, suggest that the technology did help to reduce the practical problems associated with ensemble playing. This appeared to interrupt the downward spiral of frustration and lack of confidence in playing for some young people, and enhanced the likelihood of feelings of enjoyment and belonging.
