#BikeIsBest and the University of Westminster’s Active Travel Academy have released a report which reveals the general attitude in the UK towards e-bikes as well as a variety of their benefits, including the reduction of carbon emissions in comparison to electric vehicles (EVs).
A poll of adults conducted by YouGov suggests broad support for e-bikes as a means of reducing carbon emissions, even amongst those who are not currently considering purchasing an e-bike.
As part of a rapid evidence assessment, the #BikeIsBest and Active Travel Academy report highlighted the benefits of e-bikes, including carbon emissions, health, economy and widening cycle use.
According to research by Philips et al., “e-bikes are substantially lower emitters of carbon across their lifecycle when compared to both fossil fuel and electric cars.” While e-bikes perform the same as battery electric vehicles in producing 0kg Scope 1 per km, research by Fyhri et al, states that they have substantially lower Scope 2 carbon emissions than electric vehicles due to their lower electrical power requirements.
Additionally, when considering their full lifecycle emissions, including manufacture, maintenance and disposal activities, e-bikes are substantially lower emitters of carbon in comparison to both fossil fuel and electric cars. According to the report prepared by #BikeIsBest and the Active Travel Academy, achieving widespread use of e-bikes as well as conventional bikes could replace three million car trips to work, and 10% of carbon emissions from commuting.
As stated in the transportation research by Castro et al., “e-bike users and users of conventional bicycles have comparable overall levels of physical activity, because e-bike users take longer trips.”
The health benefits of e-bikes are similar to those of conventional bicycles. The physical activity required to ride e-bikes is less than that of bicycles; thanks to electrical assistance, riders can sustain a moderate cycling speed at a comfortable level of exertion across a range of otherwise challenging riding situations. Adding to this, e-bikes emit less particulate pollution than electric cars and have a positive impact on local air pollution.
“Enabling more people to commute to work using e-bikes would increase life-expectancy and reduce absenteeism, with a potential health economic benefit of £2.2 billion per year,” according to the #BikeIsBest report.
E-bikes present potential economic benefits besides those associated with improved health and reduced carbon. According to the #BikeIsBest and the Active Travel Academy report, in 2019, road congestion imposed an average of 115 hours of lost time to the average UK driver. This congestion is largely due to the lack of road space, which could be freed up if more space-efficient solutions were adopted, such as e-bikes. This not only applies to cars but also, according to research by Verlinghieri et al., the use of (e)-cargo bikes could counteract even more congestion by replacing LGVs.
Widening cycle use
According to the #BikeIsBest report, “because of their potential to reduce the physical exertion of cycling and therefore overcome barriers of fitness, topography, and proximity of housing to employment and other activities, users of e-bikes can encompass a wider diversity of age, gender, physical fitness and economic demographics than conventional bicycles.”
A Swiss study found that middle-income groups were just as likely to use a conventional bike as an e-bike, both high- and low-income groups were more likely to use an e-bike (Rérat, 2021). This suggests that whilst e-bikes may appeal to higher earners as an additional transport option, they are also used by those on lower incomes as an alternative to more expensive transport options.
As stated in research by Philips et al., e-bikes have been identified as a means to alleviate the economic vulnerability to increased motoring costs for those living in areas in the UK of high car dependency and low income. Adding to this, the research also suggests that e-bikes could appeal more to people of different ages and genders.

Scott Purchas, campaigns consultant at #BikeIsBest, said: “The future is electric but not in the way people might think. All of the focus for subsidies has been for electric cars, but this new report demonstrates the substantial benefits of electric bikes and how essential they are for rapidly decarbonising transport, improving our health and cleaning up the air at the same time.”
He added: “We are lagging behind countries in Europe who have used subsidies to accelerate the shift to e-bikes. Given rising living costs, this report shows that an e-bike subsidy would have a very positive impact across a range of backgrounds, as well as reducing congestion even for people who don’t cycle.”
