Hello, I have found a few threads about wheel size and leaf motors and they were incredibly usefull to get started.
I am planning to add a rear hub 100W 48V or 36 V 750 W to my trike. It's an ICE Trice QNT from 2008 with 3x20" wheels (tadpole). The back end is suspended and I might add front suspensions.
Where I live (Bruxelles), everything is small (a lot of stop and go). The max distance I have to make is 10km one way, and there are a variety of short steep hills, longer small grade climbs but also long flats. The speed in town is max 30/35 km/h on the flats, but most of the time 25/30km/h (that's with my "normal" speed bike). I am not sure yet but I might like this engine so much that I could do countryside trips with it as well of approx 80/90 km where I might want to go a bit faster (35-40 km/h) and some hills but never longer than 4 or 5 km and max 10% grade at the steepest.
I am planning to buy the rest of the kit at ebikes, like a phaserunner controller. Maybe EmBev for the battery.
I am also trying to keep my current 9 speed cassette and related rear drive train (I have a 3 speed front gear). What is the best engine for my purpose?
The 750 or the 1000W? Also I am a bit lost with the battery. I thought a 48v approx 12AH or higher.
I need a 135 mm wide axle for my back end fork and I am not sure that the new leafbike engines will allow 9 speed cassettes. They have now a new splint hub apparently but I am not sure what it will allow.
I also sent leafbike a mail to have rear cassette compatibillity information but I would much appreciate your advise and experience
