It's already have 3500Km of use and the battery is slowing down. I could used it 40 km before needing to charge, nowadays I'm worried when I had to do more than 25. But is enough for going and coming back from work, and the office bike park have energy outlets so I can take the charger to work when I'm worry about it.
Yeah, hence why I'm trying to convert my bike into an ebike. I've never tried biking up it. I know I could walk it easily, but it'd probably double the time it takes.
At a minimum, the conversion should make the hill manageable even if it doesn't make it easy.
That, and keeping up with my friends on trails will be nice.
