Re: Kuberg freerider owners look here if you don't like fire.

Not sure that would have caused a fire, but good catch either way! You never really know

Do you have any pics of the inside of the Kuberg battery? Curious what chemistry/cell type/config

Just watching the videos and not being able to understand any of the language you can clearly see that he is showing you all the issues he is having with the bike. At the price tag they are paying none of them should be happening IMO You can tell that the bike is pieced together with a ton of random...

Re: LR Big Block Motoped

How do you think this new motor would compare to the D7500? Yours weighs less but your motor casing is much smaller so id assume this has similar copper fill and the new IPM can increase RPM greater than d7500? Max speed 4500Rpm Rated speed 4000Rpm Rated output 7.5 kW 72V Max output 10,000W Rated To...

Re: Kuberg Freerider Extended Swingarm Project

Well the worst thing has happened! I lost a cell in one of my Multi-star packs.....uggg I basically let the bike sit inside my warehouse all winter, i did check a few of the packs with a battery medic, and i also let a friend ride it once to stretch her legs. But there is one Multi-star pack that is...

That is done with the Grin controllers (maybe CAv3?)

to simulate frictionless freewheeling with non-freewheeling motors

Skimmed thru that link real quick but i'm using Kelly not Grin and not a geared hub motor, not sure how this helps?

Re: Denzel 72v 4-spd Gearbox Build 125cc Dual Sport

I have never actually looked into this on a Kelly controller, But does anyone know if it is possible to have the motor continuously run at a low RPM even when the throttle is not applied to simulate a engine idleing? This may help with the shifting a bit

Re: Denzel 72v 4-spd Gearbox Build 125cc Dual Sport

I would have to say no on the increased speed of 60-70mph since the motor is only 1200w once you get over 40mph wind resistance is a big issue and it would need over 2500w to sustain those speeds on flat ground nevermind a hill. You would likely overheat, but you never know if your lightweight and r...

Re: Denzel 72v 4-spd Gearbox Build 125cc Dual Sport

So i took the bike out last night for a rip, took the battery back apart for only 15ah since it makes it easier to throw in and out around and i now know this drive has its limits. It is still a ton of fun to ride around and the kids love to ride double on the back, they are so scared of the thing b...

Re: Denzel 72v 4-spd Gearbox Build 125cc Dual Sport

Hi skeetab I suspect actually you are using too high a gear rather than using the motor revs a bit more. Like going to top gear when you can't hit half the top seed is just putting lots of current through the motor. Seems like maybe something has shorted also. See if there's any burnt smell in the ...

Ya i agree, shifting is much smoother when you leave it running a bit while shifting... So i doubled my battery pack to 240 cells 20s12p for a 30ah pack. I got out on the bike going thru the typical few miles of trails hopped the few downed trees, crossed a few rivers while trying not to dab and get...

Re: Denzel 72v 4-spd Gearbox Build 125cc Dual Sport

It is really hard to shift at the moment, not sure if its because the drive is new or not? If i had to guess its 2x harder than shifting a honda motorcycle. To go further into detail, before i added the hand lever, it was impossible to shift the little chrome foot lever im using with your hand...it ...
