Here's what I know:
-the bike is about 280 lbs
-It is 87v 800W controller
-10kW brushless motor
-5 battery array, sealed lead/acid gel batteries
-3 spd/torque settings (lower spd = higher torque kinda deal)
I would like to see 50-55 kph ideally in 3rd speed setting, or in bypass mode. Right now, the bike goes 30-31 kph max governed, 33-34 with a super fresh charge max in bypass.
I have loaded the bike with a 500 lb net/nearly 800 lb gross, and the top speed unchanged/negligible on the flat. Can still climb in spd 1 unassisted to abt 25 deg incline (the steepest iv'e tried)
The current range is unknown, but carrying 300-350 net she has carried me 92km on a single trip across part of ontario, but was slowed to about 12kph in a kind of "limp home mode" for the last 700m or so.
I would like to keep the wonderful torque, but add speed as an option if i need it. (like a sub system with different torque/hp ratios for speed) that I could switch to.
I am also thinking to design a LiFePO4 array with a low voltage cut out circuit that shuts off power higher, to compensate for ambient temperature drops. I was wondering if it would hurt to add a little extra voltage while I'm at it.
So is it feasible to "pimp" this out to my specs without changing the motor itself? I am thinking to just increase input voltage -but I am doubtful as to the actual amount gained by adding 12v more in series
any help would be great
