The efficiency of the power chain incl. the link to the documents is above (I found about 97%). Also, the efficiency of the “digital” drive (according to the article here on VTM, see above) is just over 50%. The efficiency of obtaining – storing – using energy from recuperation will not be much better, in addition to the generator, engine and electronics, there is also the charging / discharging efficiency of the battery. Or in other words: you will spend almost 2x more energy by pedaling than on a classic bike, but thanks to that you then go down it, you will gain energy to climb the next hill. Take infinite advice from this, where it will settle down. Summa Summarum: in the ideal case, with a lot of recovered energy (a route where you would be forced to brake enormously on a classic bike, typically from emergency stop to emergency stop in the city) you will be on an electric bike without a chain with a battery TOTAL more flattened VERY AROUND 1/3 MORE compared to the good old chain shock absorber. And it will pay off. Of course, the estimate is rough, feels with linear dependencies and does not take into account extremes, for example, the fact that you can use a charger in the pub a little 🙂 Not even the fact that on a classic, in hilly terrain, potential energy turns into kinetic energy during the descent , so there is still some distance behind the hill of inertia. And if, on the other hand, there is a stop below the hill, the recovery rate is a little less nonsense. There are a lot of model cases, how do you want it to sound? MP
