I’m starting a new job, my cycle commute will increase from just 6 km to 18 km (and a few more as we’re going to buy a home). This is on the edge of my fatigue anxiety so I’m considering an e-bike. Not only is it considerably cheaper than a beater car due to tax and insurance costs it’s faster overall even with the European 25 km/h speed limit. The bus of course takes twice as long and costs around €1500 per year. Talking to various dealers and reading online it’s crazy how many new models there are this year. Giant alone have 38 new models.
