After having ridden my fatbike for four months, I decided it was time to do the conversion to an electric motor. This was my plan from the beginning. However, now that I was in the southwest it became more urgent. Where, it seems, everything is either up or down hill.
I purchased a mid-drive motor kit from LunaCycle and had it delivered to a town nearby my camp. It is the same set-up that two of my friends have; so, I received lots of advice and help. A couple of trips to the hardware store for some minor items, too.
In my eagerness to get it done, I neglected to shoot photos of the tear down and build. It required removing the peddles, chain ring, and bottom bracket guts. In addition, all the handle bar items, like grips, gear shifter, and brake handles.
The completed build included the motor and battery, a new chain ring, new brake handles that send a signal to disengage the motor when braking, a sensor that does the same when shifting gears, a thumb throttle, a speed sensor, power switch, and a display that monitors battery charge, speed, power level, trip mileage, and time. I also added seat suspension, new grips and a rear view mirror.
The system is peddle-assist; which means the motor engages when I am peddling. That greatly helps on hills and rough terrain. It also means I can still ride the bike as normal with the motor turned off; so, I still can get useful exercise. My fat eBike is a pleasure to ride and allows me to go places I might not otherwise.
