Thanks for all the input! I do have a watt meter for the plug in, I'll have to check it out. My batteries are supposed to use Samsung 21700 cells and the chargers look top notch chinese stuff, the bike came with two chargers since there are two batteries.

Don't think there is any way to check current flow on my setup. How long should a guy leave them charging after the green light goes on using a 3.5a charger on a 20a and 15a 72v battery pack? For the most part I leave them at less than 80%, but occasionally do a full charge, intentionally or...

I charged a couple 72v batteries for the first time, it took longer during the last few percentages and assuming it was balancing, the time was maybe doubled but only by half hour or so.

Regarding hands off riding and the front wheel wobble, I measured both my motorcycles at approx 30 degrees caster using the head tube, the bikes were approx 20 degrees. Ten degrees is a big difference.

Ciphering more on the throttle settings, I had the throttle delay set to slowest, there are 0-3 settings, the book says start strength and I was trying to soften the departure kickoff, it is actually throttle delay. Set it to 0, no delay, and it is normal throttle operation. There is a...

Interesting, thanks for the info. Hadn't thought to google it. Just finished putting it all back together, the more times I do this the better I am at getting the wiring routed better and in the right places. I did use the copper paste, don't know if it is going to make a whole lot of...

The aluminum and copper antiseize comes in a paste, it would fill any voids between the two surfaces. The heatsink paste in comparison would act as an isolator. The only reason they use the heatsink paste is it doesn't conduct electricity, on the bike where the controller mounts, the screws...

Ah. That is what it was then. Thanks for the info! I wasn't aware there was such a thing. Looking at the thermal conductivity of that stuff is like .671-4.8 w/m-k. Copper is 385-397 w/m-k and aluminum is 205!

I took a look at the inside of the crank box where the controller sits and pulled it out. There was a white pasty substance that looked like permatex teflon paste used to seal water pipe threads between the controller and mount. I didn't understand what it was and figured it was something to...

Thanks for the pics, how often you do a tear down and regrease?

On the delay thing I can hear the motor turn, then the delay until the ratchet or whatever catches and it accelerates, then the gear whine comes on. The gears have a definite whine, different from the motor. Getting better with this throttle thing. Chazmo, is the bafang geared?

When I signed on for this gig, I couldn't find a handle. In this group of ladies I meet with one was named Marcela, close enough for me, so I took it. Funny how all you buggers project onto people what they should be like. I've been riding dirt bikes for 50 yrs, karts, pissed a lot of money...

Agree on the throttle deal. I like to be able to modulate from the standing start and know when it is going to accelerate. Your tip on throttle position helped, I was full throttling when I wanted it to pick up at close to max spd and it took forever to power up. I guess full throttle will...

Can't believe how much fun these big bikes are!

I just joined an ebike facebook group for over 60. They asked are you really over 60? I replied 'really'. I got in 😁

Thanks for the info on the throttle twist. That is one thing that I definitely need to adjust to, especially in making a slow speed turn!

I've noticed the high speed runs will really suck the juice. Think I looked for the Big boats and couldn't find any, I was looking for a smooth tread anyway, not a lot out there. You guys have the throttle delay? That is a killer, especially with a motorcycle in the stable.

Roger that. I thought about the tire spinning on the rim but hadn't considered the tube. Think I'll up the pressure and see what happens.

What are you guys using for psi for the 4" tires? Wired recommends 28-30 psi. I am down to 18 psi and think that is in the neighborhood. And I don't know if this is related to the lower psi, around turns the tires feel kind of squirrelly, might that be related to the lower psi or the knobs on...

The Warrior does have the RST Guide front forks, it is spring suspension with preload and damper adjustment with lockout, the rear is air shock. The Predator is supposed to have the air front forks with 150mm of travel. I don't see the spring as being much of anything to write home about, the...
