Re: Trials Motorcycle - 1st Build. Qs-motor +Votol

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...

Re: Quietest motor for making a mid-drive

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...

Re: HubMonster mid-drive (who says chains have to be noisy?)

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: Can charging my bike be made easier?

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...

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

Looks great! That's my favorite color other than black!

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...

Re: qs 1000w builds

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 :lol:
