Yall may have seen this before but being a cruiser/Harley guy I had to share. Purely aesthetic purposes but still novel and cool!

A V-Twin motor/battery setup that actually looks kinda cool.

I absolutely love the look of these bikes. I just wish that I could find a price.

Here is a link to a site where the builder posted threads for its entire build-

Also for the other board track bike-

Lots of info for both bikes.

Now I am not too good with this electric stuff, just learning, but from what I read about this bike it uses 24 Headway 38120 10ah LiFPO4 batteries in a 12s2p set up at 36 volts running a 1000w/1kW motor
The claimed specs are
Range- 10 miles at 20mph
Top Speed- 37mph
Now like I said I don't know how to do this electric math but the way I did it was-
14 batteries at 10ah each= 140ah which = 5.04kWh
Operational Weight of Bike-70lbs
He really only getting a 10 mile range out of a 5.04kWh battery set up that's only running a 100w motor?
Why does that seem so low to me?

12s 2p is a 12 x 2 configuration of 24 cells.
Voltage is 12 x 3.2v typ = 38.4v
Amp-hour rating is 2 x 10Ah = 20Ah
Total capacity then is 38.4v x 20Ah = 768 Wh.

Indeed so I was completely wrong, it's only a .768kWh capacity than. Thanks.

And with that math... he's actually doing quite well. :)
