Few photos from yesterdays ride, i had hopes of trying to kill the battery but only managed 16 miles of the freezing cold weather.

I can't see those pictures. Anyone else having trouble?

So I took the entire bike apart after my 23 mile ride. I wanted to change the bike height so bad

I raised the front shock mount two more spots so it is almost all the way maxed out, there is only one more hole which is for 240mm shocks id imagine.

It looks much better now but it is slightly too low now since I still have the 200mm shock in place. I did order a new 220mm shock that is much better so it will soon be the way it is supposed to be!

Then maybe I can get a better feel of how the frame really handles.

Bad picture but you can see how much lower the swingarm is to the ground now

After a 23 miles ride the battery just randomly shut off on me while I was 3 miles away from home...this bike completely sucked to pedal with this akward pogo shock and no power at all!

Right then an there I decided to buy a DNM burner 3 shock like the Kuberg has on it, much nicer

I imagines the battery would take more AH that this but it went 23 miles on about 16ah in...it is a 21ah pack so im not sure whats going on there we will have to cycle it a few times, I did only charge to 61.5 which is not fully topped off

Should be fixed now
It is thank you. The bike looks good, and looks better with the new adjustment.
Sounds like you may have a bad cell group. Check each with a multimeter and see if one is unusually low.

Here is the second day of my weekend ride! This is before I adjusted the shock mount and bought a new shock and controller...

stay tuned for more updates! Darn thing died on me I may have a dud cell somewhere not sure

Got the shock in the mail! Don't know why I always cheap out and get a pogo and upgrade later. Luckily got this as a new takeoff for only $100
Image
Slapped it on real quick, left it in the center spot on the swingarm not sure if I will keep it there or not
Image
Can already notice a difference but the front wheel is slightly raised in this picture

The geometry looks better now.
I always adjust the geometry so the bike is stable when riding hands-free. The fork angle or rather the trail of the front wheel is important for that.

So I liked the speed of the 15s battery pack but I didn't like how the controller didn't have regen and the throttle was awful and I couldn't fit the key switch into the bike. I ended up getting a used 6fet mini em3ev controller (thanks forum member Mudflap5) with regen and cruise and I was able to fit it into the frame. I am using a 10s 13.2ah pack so I will have to test the range and compare it with the other setup that managed 22miles and was fairly heavy. Also the controller is in the frame and not hanging down below in the weather.

This controller also has a three speed switch but I just hard wired it to be in 100% mode, for now the regen turns on when the throttle is release im not sure if im going to like this for coasting, but im going to try it out for a few rides to see if its beneficial to the range.

Temp wiring process, at first I wired the throttle wrong, this is the first 3spd switch cruise controller ive ever had
Image
Put a small piece of foam behind the controller so it doesn't bang against the bolts from the seat stay and shock mount
Image
Zip tied the controller to two of the four mounting holes in the frame(not sure if that's why they are there or not)
Image
Was able to cram it all in the frame with a small 10s 13.2ah 18650 battery, and now fit the key switch
Image
Flipped it back over to finish screwing the housing cover down
Image
Key switch! Supposedly this controller has zero load when low voltage wiring is switched off so im going to try it and just leave the primary wires hooked together. I will monitor this for a few days to see if it drains
Image
Adjusted the shock rebound and I am so much happier with the bike now!

also went back to my trusty old half twist chopped down, after only 20 miles on those vertical thumb throttles and I never wanted to see it again...talk about hand cramps

Looks good, although I'm a bit paranoid that foam is going to melt if your controller ever heats up.

Ya I thought about it, but there is plenty of air in the space and its only a 20a controller. I usually always have them exposed somehow. I am going to give it a try for now since it looks nice and neat.

Well I just dropped my truck off for a oil change and rode the Vector light back to my work. One thing I did notice is now that my swingarm is in the correct position the inside back of my feet hit the lowers of the swingarm tubing while pedaling now if I am not careful. It wasn't as bad when the shock was in the wrong place. It only took a second to adjust to it and I can still say that pedaling is pretty comfortable. Its not crazy bow legged at all like on large ebike frames. The frame fits me really good now and my stem and seat might actually be slightly too far apart now!

The 10s battery setup and controller work great together and my top speed is pretty much 20mph now. The regen kicking on when you let off the throttle is bad at times until you get used to it. I actually kind of like it! You can be really aggressive with the throttle and just let off on corners and it slows down for you. You almost don't even need to hit the real brakes and you can make a game out of this for fun while riding!

The speed may get boring to me, but this is a commuter bike to basically get out and enjoy the day on and listen to tunes, so I may go higher voltage but for now it is ok, also this let me pedal effectively now since my pedals max out at 20mph

I did have the chain fall off the front chain ring and this is a big problem. It has happened consistently on every ride over bad bumps or curb hops. I thought my chain was tight enough so I think I need a chain tensioner or a front derailer.

this 20mph with auto regen is perfect for the freezing cold weather we are having right now, but again I just hopped onto the bike to take a trip to the store and the first thing I noticed was the inside of my feet rears hitting the lower portion of the swingarm when I pedal... It is starting to bother me a little bit. You have to expect it and change your stance a bit which prevents me from wanting to pedal at all...like I need another reason to sit on my ass.

I will need to get a full ride in with the new bike stance to see how I really feel

i ended up using a slightly longer bottom bracket to bring the crank arms out a little bit more... otherwise my original crank arms were hitting the swingarm, but i think it depends on your crank arms, some come out a bit farther than others. I just had a few bottom brackets laying around so i used that, but afterwards i found a couple crank arm sets that look like they have more of a curve on them

Ya Dave I think I will have to put either more bowed out crank arms or a wider BB on the bike to make it not happen. Its just a shame because the front of the frame is nice and skinny and doesn't effect pedaling at all, but the rear tubing I think is somehow wider than it needs to be for 135mm hub frame.

I can see why though...every build now is all about the most power possible 10kw!!!! 15kw!!! Big moto tires!!!

I have a different bike for that :)
