Yeah those stock seats are not for the commuters like us.
I have a Selle Royale and it is great, never a soar but. For me, when I buy a 10 grand bike it hard for me to see a cheap replacement/accessories for it.
Thanks for the light comparison. The Chinese is always lying, When they say 800 lumens then it's really is 400-500. Serious vendors(like Surefire) measure output a few cm from the reflector itself. Chinese measure theoretical output and is never the same as practical.
A have a magicshine 872 and they claim 1600lumens, but in reality it is a 1200lumens light.

My VBOXX is going to the factory as it is not possible to fix, and with the bike in pieces I might as well paint it with matte black plastidip. With the bomber 888 in black it´s going to be a real stealth bomber.

Where do you guys buy brake pads for the Magura?

I bought a set of these

Morati said that they are more silent. And yeah, they where, when I put them on.

Thank you neighbour! I will try those. Do you use the semi metallic or organic?

Am I reading this correctly? The motor was red hot? If you got it that hot, your motor may be done. Put your nose as close to the motor as you can where the Phase wires exit the shell on the disk brake side. If it smells burnt, you have a problem.

That's a bummer about your Vboxx. But it is a great reason to repaint your machine.

Yeah I'm sort of like that too, but I've never sampled a seat of this type that I liked. Before trying it I was thinking it would probably end up on the pile, and I didn't want to spend a bunch for something I probably wouldn't. Now I know how comfortable they really are.

This one will work for me now, but a nice thing about the real ones is they're leather, and come in different colors, and textures. Mine is the hide of a Naugha.

When I use the regen it loosens up my rear axle bolts, so I don't ever use it. I think it's really just more of an gimmick anyway that Stealth is forced to put on their bikes because other manufacturers do so. The amount of charging it does for street riding is so little it's not worth the trouble imo.

I respectfully disagree TV. Regen isn't a gimmick. I average around 10% regen on hilly streets, energy that would otherwise have been wasted as heat off the brakes, not to mention massively reduced brake pad wear. It's usefulness is related to the steepness of the terrain on which you're riding as well as the actual surface. It's much more useful for street riding than off-road. On streets, I use it constantly, so much so that I only use the hydro's to come to a complete stop. Off-road, it's the opposite, I return to the hydro's and never touch the regen button.

Also you can prevent axle slippage with an axle clamp or Loktite.

Strange, on my Bomber, the clamp prevents any slippage. I just make sure the bolts are tight, wheel aligned & chain tension is good before I ride, hardly ever any adjustments necessary. On my Fighter, I have no clamp, no Loktite and still no slippage and I use regen much more on the Fighter.

Don't get me wrong, I think that clamp is a good thing. It surely will stop the axle from striping in the drop outs. Sometime I'll investigate what's going on, but right now I don't really care about the regen enough to bother. When I don't use it the axle bolt never comes lose.

TV, regen does work and work well. Its better at conserving brake pads than recharging the battery. I spoke with a guy that climbed pikes peak. He road back down that 19 mile long steep road, he recharged 100 watts into the battery from regen braking. considering how steep and long that road is, not much return. Wheel tightenging sequence is key to regen braking and not loosing up axle nuts. Always tighten the left side first, then the right, then your pinch torque arm@4nm. You wont have a problem with nuts loosening if you tighten in this order.

Maybe there's some technique I don't understand about that clamp. When I changed my tires, I just pulled the wheel off and put it back just like it came off. I never touched the clamp. When I got it back together, I thought it was just like before I took it apart. I didn't think you needed to touch the torque clamp?

It was time for my Fighter to get some gears. One of the previous owners had removed the Schlumpf so it was like riding a 35kg(77lbs) BMX! :shock:
I was unimpressed with the slack in the torque plates so I added some torque washers to help.
Soooo much better with gears, did the first 10kms of my ride today through single tracks only using 1Ah.

Nicely done. I can attest to the fact, even with a Shlumpf, how much more versatile the Fighter is with a derailleur.

Where can I get some of those torque washers, they look like a good solution. I have the same issue as TV, where the torque clamp doesn't prevent play in the axle. I would say this is partly due to the fact that the torque clamp notch is smaller than the dropout slot, letting it move under load.

i didn't smell anything burnt when it happened. I reset the BMS as others suggested and was able to charge my bike again. why exactly did I have to do that anyway? Had the batteries run flat?

the motor is working again....but for how long?

Looking at the clamp I started thinking there's maybe a trick to it. Before you tighten the axle bolts, maybe you can use a wrench to twist the axle one way, while you twist the clamp the other way to take up any slight slop in the drop out, then tighten the clamp down, and tightening the axle bolts last.

Has anyone tried this?

If I figure out how to stop it from loosening my axle bolts I'll probably have a higher opinion of it. As far as saving the brake pads, I was never concerned about that on any of my other bikes, but on this one I can see why that might be an issue.

I had the same problem with regen braking which caused me to build my own pinch torque arm because Stealth didn't offer it at the time. I got one now that I will put on when I get the 5405 laced up and going. What you said above is why I said tighten the left side first, what little play there is between the axle and dropout will be taken out by twisting the axle clock wise during the tightening process (Looking from left side of bike) until it stops in the dropout. This is the counter direction your axle rotates when you get on the gas. When that's done then tighten the right side, then take your pinch clamp torque arm, if the dropout tab is facing towards the rear, use your finger and push upward on it while you tighten the bolt. I have a home made pinch type torque arm I use. Its a little different with the set screws on top so I can take out all possible slack. But this the tightening process I use and it works.

If it didn't smell burnt, and you haven't noticed any power loss when riding, your motor is probably fine. As far as reset on the BMS, the BMS tripped so you couldn't over discharge the battery and ruin it. Just note how many amps or watts you had consumed when your BMS tripped and try to avoid that. My battery on my Bomber has a total storage capacity around 1440HW based on settled voltage charge (80V x 18Ah). But if I go over 1290 WH consumed @ 70-85 F (26C) outside temp, or over 1310WH @ 100+ F (38C) outside temp, or 775WH at -11F (-24C) outside temp, and blip my throttle WOT, the bms LVC trips and cuts power off completely. Because of the 20% guideline that Remf and other mentioned earlier, I don't discharge more than 1200WH which is just a little more than 80%. Those number I referenced are from my own personal data findings and observations. IMO, it behooves the rider to know what his/her own battery's capabilities and limitations are so BMS shut down can be avoided.

Yeah Rix, same here my BMS is probably bored by now. It never had to cut the power in the last 2 years.

I do the same. Never discharging the battery to more then 1200 w/h. The pack is as good as new and shows no signs of failure at all. :mrgreen:

Stealth rules!
