My electric moto experience is limited to the little oset bike i bought for my daughter. I would love a Redshift or Light Bee to be able to ride my own and adjacent farms quietly but this project might suffice until more play monies are available.
I would love to find a combo that would ride like a normal offroad dirtbike for an hour, weigh about 200 pounds and cost about $2000.
Here is my rough outline
12 KW motor/controller kit: http://www.thunderstruck-ev.com/budget-screamer-72v-brushed.html
$1400 and 40 pounds
DIY 18650 batteries 20s10p somehow configured
$600 and 40 pounds?
Here is the free roller someone generously donated to the cause. I was looking for a perimeter framed Kawasaki thinking battery placement would be more flexible. I had a gas kdx200 so I know the chassis will perform well enough on the terrain I wish to ride which is mostly 0-30 mph singletrack. I'm surprised this skeleton weighs 130# but I think if the project proves worthy, I can shave some weight off the wheels and forks.
So far $2000 and 220# estimated. 200 18650 cells at 2.5Ah each in a 20s10p pack gives me 25Ah and 1.8kWh at 72 volts?
Am I way off on anything here? Ride time is a big unknown for me and maybe the proposed battery won't come close to one hour. My last trailride loop was 19 minutes with a rolling average of 9 mph, 24 mph max. Not sure how many kW it takes to push 390 # offroad at 10 mph...
I don't know what I don't know and look forward to learning with some guidance or suggestions
