Re: EM3ev vs Luna Batteries and Kits

EM3ev seems to have things on sale at cheaper prices than Luna. Is there a reason to buy Luna over EM3ev? It seems like you get more battery for the cost with EM3ev and the BBSHD is also cheaper. Am I missing something? Afaik em3ev ship from china and Luna from US. Depending on where you live you m...

Re: New 4800W Cyclone?

One question Is this motor square cranks only? When I ordered mine I recall asking for the square taper version, these must have been another choice for me to do that. I asked cyclone more recently and he said it is square taper only. For chain selection I would get 219h or single speed chain cogs ...

Or a pogo stick why not.
Seriously. Opinion only. The big box enduro frame design is tired and overkill. An alternative is a departure from this frame.
I meant just the swingarm with the motor integrated. The frame is dog poop.

Re: New 4800W Cyclone?

Ok I should have used imagine. Basically figure out how to mount the cyclone 4.8kw coaxial and possibly also the swingarm to this frame. This could be an alternative to the Enduro frame. It’s obviously not going to be bolt on and go by any means. Combining the motor with the cranks clears up a lot ...

Re: adding a throttle to turbo levo?

Last time it was discussed, a conclusion was made there is no way for the motor to spin without your crank spinning too. This is because it is built for PAS only and is missing an internal clutch. So for any throttle your legs would have to be spinning too, even if you chipped or replaced the contro...

Re: "the one"

Makes you wonder what's going on. Someone is getting scammed. I just don't know who. Given the claim of 20 patents, my first guess is that the Aliexpress bike is being sold illegally.

Re: "the one"

Dont buy anything on kickstarter. You will be high and dry without money or the item. Wait for it to be released. No, it's not going to cost double after the campaign, because no one would buy it for double. That's if it ever gets releases. People who paid $1k for this scooter are still waiting for ...

Re: Fried by BBSHD controller doing the shunt mod

Thanks for that info! Is there a safe way to discharge the capacitor in this scenario? My initial though it to hit the throttle after disconnecting the battery, but will that be enough to discharge? Maybe hook up a light bulb to the leads from the battery? Easy: unplug battery, turn on bafang displ...

Re: Magura MT5 front brakes on DNM USD-8 Fork

I bought a magura 203mm adaptor, but I just needed the shimano 203mm one when I switched from shimano to magura mt5 front brakes.
Actually, the magura one didn't even fit. Only the shimano adapter I was using before did.

Re: Sur-Ron - New Mid drive Bike

Unless you plan to keep the stock controller, why would you want to use only 16S? I would say you are better off using 18s or 20s. The sur-ron controller has an OK top speed, but it would be nicer if it would be just a little faster. This is why I plan on using 20s, that would bring the top speed f...

Re: A controller better than Phaserunner?

The phaserunner can pull all then the amps is able to provide... Not much more you can do messing with the controller.

If you get a new battery and want something similar but more powerful, you can order the cyc 72v65a (maybe 80a) foc controller when it comes to market next month.

You can see fuse on left side by the winding on my photo. White thing, 110°C on it. On your motor was the temp sensor just hanging loose like that originally or did you pull it out to show us? Should really embed it in the windings. Haha, it might be the usual cyclone way: good idea, lacking execut...

And I can confirm, that newer cyclone motors have 110°C temp fuse. I never trigered it, but its here. :-)
How do you spot the fuse?

Did it get stronger 130 to 150 or just hotter? :lol:

It would make sense making an identical but taller case with space for an extra layer... The same lid could be used then, and it's not like it's bumping into your chest anyway.

If technically possible, mid is far superior. Better handling, lighter, much more torque with gearing, able to be liquid cooled. There is a reason Zero bikes, Harley, Lighting bikes all have mid drives.
