Endless Sphere

Decided to take a few steps back in my project. I feel this is a very good thing. I sold my QS Motor/Controller/Speedo/Throttle - the whole kit! Absolutely nothing wrong with it, and QS quality seems to be VERY GOOD. Why the Change then you ask? i think you made the right decision. that new gearbox...

qsred.jpg well the 20mm shaft is back with their new motor w/ built-in 2.35x gearbox Is it available somewhere, or is there more info somewhere? I saw something on facebook, but not much info except the gear ratio. $308. preorder 50% downpayment just email them. the aliexpress link just serves as a...

IMG_20200716_181103crop w logo (Small).jpg the qs 120 70h is a low-kv motor (38). not as "slow" as a hub but you probably won't find a lower kv that's readily available at a reasonable price. the BHT is 36kv but out of production to keep noise low don't use anything smaller than 13t. and use a larg...

seems to be the same 20mm. let's hope they improved the metallurgy and heat treatment

well the 20mm shaft is back with their new motor w/ built-in 2.35x gearbox

btw i do have some play

IMG_20200724_205930.jpg Did you have a premature motor shaft wear problem? A friend only did 100km with his Qs 138 70h. how prevalent is that issue? btw what chain is that, the sprocket must be narrow like #415H? probably why the shaft stripped like that btw here's my QS 120 shaft. seems to be doin...

what's the max "safe" boost current for em100?

and how the heck do you tell if you've got an em100 or em100s ? or em100sp

overall this setup works so much better than when i had my motor on the swingarm In what specific ways? I want to understand. I think it's guys being so accustomed to the feel of the traditional way using gassers that they don't like the feel because it's new. To me anti-squat and anti-dive are des...

re title, i do like the sound of a 10t motor sprocket spinning fast, seems to wear chains though :lol: btw i tried that once, putting the motor on the swingarm, even went as far as centering it on the pivot axis. it still retarded the swingarm movement. but it's fine if not going off-road You must ...

Wow. Nice build there Overclocker. I didn't do a build thread. Motor is a Cyclone 7500w What did you do for throttle and controller? I did Kelly KEB7200 and some 0-5v throttle off Ebay. Even after dialing on it a bunch it's only somewhat better than an on off switch. that's weird i do have a few ke...

a light weight prototype e-motorcycle I made.

Sweet looking bike. Nice job.

agree. and very similar to the one i made

nrvwaters, what's the motor? you go a build thread?

Is it OK to float-charge a maintenance-free "sealed" car battery

lead-acid starter battery. typical 12v found on ICE cars

just wondering if a continuous float charge (around 13.5v) is OK to maintain SOC and prevent sulfation

get some vinyl tubing and a metal coil spring that'll fit inside. dip in boiling water and form the bend you want. let cool in cold water. voila permanent bend no kink

9JjLhp5uX6w improved the time a bit. but the start wasn't good. i was fully leaned forward but the front tire was still lifting Looking good man! I also bought the Votol 100 have not had the chance to put it in yet! votol is pretty good. just buggy :lol: btw when i got mine it was in some kind of "...

this is the Drag Racer app

17s battery not fully charged. votol em100 at 120A, flux weakening at 2800

Looks great! That's my favorite color other than black! You should paint the swing-arm too. yeah it's my favorite "bright" color too. for some reason bright orange seems to look old the longer you look at it btw the color scheme reminds me of my Ryobi power tools. i'm tempted to put red RYOBI logos...

The bike looks great. Any footage of the bike in action? It would be good to get an idea of the performance of that motor and controller setup. will post one soon. i just finished the upgrade to 428 (from 420). minimal weight increase as long as you use 428 chain not the heavy-duty version 428H. wh...

drip some Deoxit red into the switches

420 and 428 are very similar. 428 roller dia is just a bit bigger so it's possible to grind a 428 sprocket into a "420"

how do i know? because i've done it
