I briefly mentioned this bike before, when I talked about how I got into bike repair. The bike was “analog” back then, but my wife has meanwhile developed some problems with the tendons on one of her feet, which have impeded her ability to climb hills on the bike. So I’ve built her an e-bike! Whenever the decision to get an e-bike comes up, one of the first questions to answer is do I buy a dedicated e-bike, or do I convert my existing bike?
