I think if you’re trying to get people to consider cycling, the easiest option can be to get them to try an electric bike. BaNES council offers an opportunity to loan an electric bike for two weeks. Other councils offer similar schemes. The RAC in Australia offered a 10 week eBike trial at the end of which 50% of users bought the bike they had been using (https://rac.com.au/car-motoring/info/e-bike-trial).
Normal bicycles for many people are that little bit *too* hard to consider despite the immense time savings and health benefits, particularly if you live in a hilly areas. Whereas an electric bike magically flattens hills and gets you to work without being in a sweaty mess. They are just a joy to ride and people “get it” within seconds of being on one. They also give you similar health benefits to a normal bike 😉
If your company is already supportive of cycling, then it might be worth persuading the company to invest in a good quality eBike to loan out to employees to trial commuting by eBike. I’ve heard of places where there was a 90% take-up of eBikes once people had a chance to try one.
