Well today I used to come back from work and I was really surprised. The difference with scooter and motorcycle are immense: no parking required (I could bring it inside my flat), no fuel cost etc and here comes the big surprise:
I'm actually exhausted! I really did get good exercise but instead of ramping up the steep hill at 10-15 km/h I was making the same kind of effort, all red in face and stuff, but I was going at 45 km/h.
That means instead of commuting 100 minutes without motor, I did take only 40. And they were pretty much intense, as efforts goes, always going to the limit. So I did exercise, but at the same time I was at home one hour early. That's huge in my book, while with a normal ebike I didn't have that, since after 25 km/h it just stopped working
Thanks for the link, I would really love the idea of diy, I'll start watching some youtube videos.
