That gives me enough to go about 120 km at full speed ( about 30 kmh average speed). Imagine a 50 km ride plus a 2000 metre mountain climb without charging. The rack would not need to carry nearly that much weight if the battery weight is somewhere else on the bike. Unsprung would work fine. Right now I usually carry 3 Bosch powerpacks ( sometimes 4) so if that much battery power could be attached to the bike it would be a good thing. I cannot do this with only 2 powerpacks unless I go slowly. If I am trying to replace a car I need the bike to haul groceries too ,hence the 25kg ask. I could pull a trailer for Costco runs but most of the time I would rather not use the trailer. Basically wishing for one bike that can do everything.Intriguing
1. Why 40Ah?
2. Why 25Kg rack? and Sprung or unsprung ?
