have all the gears in the back to match all the conditions. Uphill, downhill, it doesn't matter, you have the right
gear for the occasion.

Indeed. This build is quite versatile:
Full suspension, albeit crappy stock shocks.
Full range of gears. I can effortlessly climb 15% grade without pedaling and reach 37 mph on the flats. I could probably do 40 mph if my shifter would get the chain on the smallest cog on the rear... I have still yet to sort out the shifting to get through all 8 gears.
I can pedal upwards of 20 mph with reasonable cadence because of the low kV wind on the motor.
One of the things I don't like is that with the 3 chains and 2 freewheels in the setup, there if quite a bit of slack or play between motor spinning and back wheel spinning. I measured it to be half a revolution of the motor to pick up all the slack in the chains and freewheels. This causes significant lag when applying power and makes for somewhat jerky performance when under small loads.
In the mean time I would like to upgrade the front fork to something better. Does anyone have any recommendations (brand and source) for a decent shock that works well for light to moderate off-road use, and will not break the bank????
