You will be very surprised how loud your bike actually was once you try out modern sine-wave controllers.
Yup, with ya there Alex. Can't go back to square now, sounds like a steam engine compared to sine. :lol:

TBH, I'm surprised Stealth hasn't moved to a sinewave controller yet...get with the times Stealth, sheesh. :roll:

Just ride a mid drive for a few minutes, and you'll never notice any controller noise from your Stealth again. :)

No shit. My SurRon and Alta make way more mechanical noise than any squarwave controller I had hooked up to a hub motor. But in all fairness, mid drives offer more advantages than the DD hub motor, except on the flat streets of Dallas/Fortworth Texas.

I've studied up on the Sur Ron a little bit, don't think I haven't. For what it is, I can't knock it. If I was interested in an electric motorcycle it would be high on my list, and I wouldn't care so much about how quiet it was. It's small, and light, that's what I like. It looks like it has a better, more dependable design, especially the primary, than most other mid drives, and it has a lot of power. It's faster then a Ruckus, and costs less than a Grom. Seems like a great bike for the money. It looks like a dirt bike, which isn't my style, but box kites like I'm riding now weren't really my style either lol :( 8) :lol:

Could you repeat that, a mid drive was riding by, and it drowned out what you were saying. :( :D

I do like those controllers though.
Now when you mention it:
Here is what I have been working on, when replacing the chain to a belt - you notice one important thing! See if you can hear that! All I can tell you that in real life, while driving on the road, the sound is really sexxy and not unpleasant in any way like you usually find on the mid drives using a chain.

Yeah, belt drive would be a huge improvement over chain. I bought the first belt drive kit for my Sportster immediately when they first came out in 1989. It was before even the stock Sportster's had belts. Of course noise wasn't a consideration because it was firing twin cannons 6000 times a minute through Thunder Monster baffles. I still can't hear as well though my right ear. :(

While we are a little bit off topic I guess I can ask you TV.
What do you thing about this mini electric chopper?

I've been looking for this little toy from a while and sounds like I found a moped registered version just yesterday from a guy here in Italy.

I think it would be great at the critical mass. It's a lot cooler looking than the rentals.

Not sure if I’m in the right thread but I’m wondering if anyone out there knows where I can obtain some shortened cranks for my new bomber? I’ve searched everywhere but no joy. Tia

I doubt they exist, but the VBoxx is made my Suntour.

You are in the right thread, and thats a good question. I have researched and even though the Vbox has an splined bb shaft, its not compatible with any other crank MFG. I have an extra crank set and am considering having a welder chop 10mm of the crank arm length.

Thanks heaps for you’re feedback guys! I guess I’ll try and make contact with Suntour and see what they have to say.

Let us know how it goes, I had no luck with Suntour North America and couldn't get a hold of anyone else.

So the night before last I wanted to ride, but there was a line of storms coming. After studying the radar I decided they were going to pass to the North of my house, heading away from my location. I decided to ride south. I got about 3 miles from my house when a mean old storm cloud popped up out of nowhere, and started following me. I could feel rain drops falling on my head if I slowed down. 10 miles farther south it was still harassing me, but I was pretty sure I could out ride it. But then as I crossed an intersection, I heard the sound of something small and metallic bouncing on the street. I didn't think too much of it. A couple blocks later my front brake seemed to have lost it's hydraulics. Closer examination in the dark revealed that one of my brake pads was gone.

Before leaving the house, I had just changed my front brake pads, but apparently I forgot to tighten the pin that holds the pads in place. Then I remembered the metallic sound I heard, and rode back to the intersection where it happened. I found the pad sitting in the middle of the street, but the pin is lost forever. That was my last set of pads too. Sure glad our bikes have 2 brakes.

By then the cloud had moved on, but the streets were soaked with water. I'm sure we all know how much our Stealth's love water, but I guess my bling fenders aren't totally useless after all, because the front kept water off my face, and the rear kept enough water off the hall plug that I was able to make it home with no further problems.

The worst part was over night my bike had dirt on it, but the next day I fixed it Allex :wink:

I think I'll give this 14T freewheel a try. The only catch is I'll have to give up the regen because the freewheel body is too wide to allow the torque clamp to fit. I think I can live without regen.

Not necessarily...remember the torque arms I made a while back. I think I might still have one left somewhere.
Want me to dig it up?

What is everyone doing to keep their motor controllers cool?? I just injected 6mls of ferro fluid to the Crystalyte motor which helped heaps and I’ve ordered some hub sinks. I’ve found some heat sink at Jaycar that will fit onto the controller but it will add like 10cms to the thickness. Pros and cons pls

I've never noticed my controller get more than slightly warm to the touch.

Thanks CD, I appreciate the offer. I don't think I need it though because I don't like using it. If it becomes an issue I'll let you know.

Any tips on bleeding magura mt2 brakes. Do you have to use magura mineral oil or is there something better.
Took a quick ride today.. new battery from Hi-C working beautifully. I had to replace the BMS due to my fault stupidity not paying attention. In a rush plug charge leads into each other and Bam bright blue Ark.
Anyway bikes running fine now.. but only using front brakes and Regen. Today's top speed 51.8mph.
That top speed is with a new December 2017 model motor. My last ride before I blew up the BMS I hit 62mph with original motor from early 2013#238.
I did not change any settings on cav-3. Some guys chimed in that that was impossible with original controller. So what does that mean? 10 mph difference. My original motor it's just freaky fast!!

Download some gps speed app on your phone, compare with CA and then adjust CA accordingly(if necessary)

FL, the MT2 are easy to bleed. I bought one these bleed kits. Before starting I watched a couple of Youtubes on the subject. One thing all the videos suggest is to remove your brake pads first, or you'll ruin them. So far I disregarded this advise twice, and both times I ruined the pads LOL. You definitely want to use mineral oil, but it doesn't have to be Magura oil. Shimano mineral oil works just as well, and probably any other brand too.

FL, check your ca and see how many amps it's set for. Mine was set for 60 amps from the factory. I set it to 65 amp, and it accelerates better, but top speed seems the same. What I notice most is higher watts at wot.

This probably has less to do with my new battery, and more to do with the different chemistry, but the stock battery was pulling around 4250-4300 watts both new, and old. The new battery is slightly over 4500w. I never saw that with the stock battery. After changing my ca to 65 amp, now I see close to 4800w hot off the charger.
