This has been a long time in the making and is well under way now so i thought it was about time i shared something.
This is my first E bike build and i certainly bit off plenty.
I needed a bike capable of climbing steep hills for fairly long stints for my commute, so i settled on a Mid drive. I was keen on a
Lightning Rods kit but at that stage last year the waiting list was enormous and there was quite a few teething problems. Then
there was the AFT which is made locally for me but i am in manufacturing and had issues with how this kit was constructed for
the asking dollars. I liked the Kranked ego kits and this is probably where i drew most of my inspiration from.
So i ended up designing a kit based on a cyclone 48V motor and gearbox, then incorporated a standard flanged freewheel at the
motor output. Then i used the Kart chain reduction idea as the secondary reduction to solve the problem of the other cyclone based
kits, crazy cadence. This is what i came up with (go easy its my first one).
So the specs are:
Specialized 2011 Rockhopper Pro
ISIS Cranks
48v Cyclone motor and Gearbox
Lyen 12 FET 3077 controller
12s3p 15ah Lipo
Freddie designed and manufactured kit!
Cheers Fred
