Power is a funny thing. When I first built my PK Ripper a number of years ago, 10,000 watts was the end of the world in my eyes for a 20 inch bike. Then my Hooligan peaked at 14,000 watts with a longer wheelbase and that seemed nuts. Then came this bike with an even longer wheelbase, more weight, and over 20,000 watts and I could not imagine more power in such a compact package. Yet, I got used to the power every time. Now this setup is the most extreme I have ever built. I cannot add any more power without increasing everything; battery, chain, sprocket, brakes, chassis bracing, etc. At this point I highly doubt I will add any more power. More than likely I will merely tailor the violent "Hit" with the final gearing to put the performance exactly where I want it.
Right now it is geared for 54mph. With two motors it was geared for 45mph. It has 50% more power with 20% taller gearing. That should give me a bit more acceleration, greater top speed (as me mentioned), easier load on each controller, less motor heat (not that they were running hot anyway), and a better powerband for wheelies. On top of that, the previous motors were 5 turn delta. These are 3 turn wye. That means they are nearly identical kv yet far more efficient. So, odds are, with similar riding, the range should be very similar to the twin motor system or even better unless I am riding it hard.
Oh, I also, am seeing up a 2.4KW charger for this bike to allow faster recharges between thrash sessions.
