This is my fourth e-build and first off-road mid-power E-Bike.
Here are my initial planning notes from 3 months ago:
E-Bike is purpose-built with these capabilities in mind.
*) Budget is $1500.
*) Engineered as off-road capable for state/national park offroad riding......Primary challenge for a Florida woods-bike is low weight while being sure-footed in loose sand.
*) Fat tire platform with 26x4" rims. Allows bike to "float" (Regular mountain bikes sink or dig-in) on sand trails & fireroads.
*) Need power to push through loose pack trails. Will most likely use 2170 cells. 52V arrangement. 70 cells (14Sx5P) build?
*) Low speed torque. Expect a bigger geared rear hub motor will do well. I dont want a mid drive.
This should do nicely for 1500w, 2000w max. https://www.aliexpress.com/item/4001314078195.html
*) I will use this frame: https://www.framedbikes.com/products/framed-minnesota-2-0-x5-crankset-fat-bike-frame-kit
*) I will use a Bolany "fat" mountain bike air fork.
*) I like performance and simplicity of generic Chinese controllers, so will be going with a 60V 50A+ controller of some sort.
*) Rims/spokes/tires get decided on after I go over motor and frame.
*) Battery&electronics will be enclosed in custom aluminum case which shaped to fit tightly in the frame triangle.
*) Will need to buy disc-brakes package, head bearing kit, crank bearing kit, peddles, crank, chain, chainring.
*) Top speed not much concern. 25MPH would be nice.
I thought long and hard about going with an enduro full suspension build, but in the end I decided to go light with aluminum hard-tail fat-bike MTB frame.
