From what I have gathered, motor temp is a key factor in the gear failures. As long as the motor temps are kept down, the gears seem to hold up.dirkdiggler wrote:That's my concern. Had the BBS02 hotter than it should be a bunch of times on long climbs. Don't know if increasing amps will fry it or help keep the temps down. Also debating whether to just get another Cyclone or grab a BBSHD motor from Luna and buy your controller for another fat bike project.

The one on the Las Vegas strip is the one that got to me the most. It wasn't too bad at first, but it quickly got very busy.robocam wrote:Which videos are you referring to? Hooning?
I'm not concerned with someone searching existing videos, they probably already have an agenda. I'm concerned with public awareness. I want to keep high powered ebikes out of the public mind for as long as possible. Every new video brings more views. So far I can only find one fast ebike video in the past 3 years with more than a million views.WoodlandHills wrote:I felt the same way at one time, but I've come to realize that particular ship sailed a long time ago. Anyone who wants can find hundreds of videos that reflect poorly on us, as far as trail access goes, that were made a year or two ago. What harm will new content do?
Good point. Also, I genuinely want us to have fun for as long as possible. I have no problem with having fun on high powered ebikes and riding in places that we shouldn't, let's just try not to do it in front of people. When you do make yourself visible you are affecting every other person who rides. Putting videos on youtube just multiplies the effect.Sean9002 wrote:

You can always upload videos to be 'unlisted' so it cant be searched but it can be accessed by a URL. That way only memebers will see the URL published.
Yep, that about sums it up. My goal is to delay enforcement of the existing laws or strengthening of the laws. Excessive risk aversion and distortion of public perception of risk through sensational viral media of low frequency high severity events is too high today for me to trust the process of law to be reasonable. Instead I advocate for self-enforcement, which is effectively what we are operating under right now with so little enforcement effort. We can continue to do so until the worst of us ruin it for everyone in the community.WoodlandHills wrote:So for you the issue is not the criminal behavior by riders of illegal emotorcycles, but their posting of video documenting their violations? That's an interesting viewpoint.......
As long as lawbreakers are only seen in realtime by the folks that they live among and are not subject to a Google search you are cool with them doing whatever they want? That's analogous to saying that shoplifting is no big deal as long as you don't put the video on YouTube because then it will make it hard on all the other store thieves out there.
As a suggestion, maybe as a community we should put peer pressure on our fellows to obey the existing laws and simultaneously work to align those laws with our needs. You know, like people do in democracies....... Or is that just too damn much trouble?

So can we figure that amps is equivalent to torque and volts are equivalent to horsepower? In a general sense?evolutiongts wrote:You will get better performance from running higher voltage vs lower voltage and high amps.
In addition, lower voltage + high amps will cause more heat in the BBSHD.
With higher voltages, the motor will simply run at a higher RPM but not necessarily need to pull higher amps.
Higher RPM's= More power overall
Although you can use field weakening to boost RPM's at lower voltages but the controller will be forced to draw higher amps, you lose efficiency and higher heat build up.
Surprisingly, the BBSHD barely gets warm at 72V compared to 48V in which it gets warmer, and I beat the hell out of it.
Or you could use an IGH with that BMX chain and have three speed ranges.......StinkyGoalieGuy wrote:That's insane. If I can hit 25MPH using 30T in front to a 42T in the rear, I would just run it as a single speed and get rid of the derailleur. I could also use BMX chain to boot. I'm fine with 25MPH and that gear ratio, as that will climb anything.
