Endless Sphere

I set up a camping trailer for hauling all my stuff that way I can keep my e-bike uniform/clean when I'm not camping. For day trips I think it better to simply haul around more battery with you but I much prefer charging at the camp site on multi-day trips over trying to find an open outlet at a par...

Thanks for the replies!

Thanks amberwolf. That's got my mind steered in the right direction with thermal control modules and voltage divider. Escs just hear "voltage" from your ebike throttle correct? Like your throttle is just a fancy potentiometer that changes the voltage from 0 volt to 5 volts or something like that rig...

Does anyone know the actual weights of these Hallomotors?
Every motor is listed at "5.8kg".

Hi, I've been out of the "buy new stuff" game for quite a while now. I have been riding my most recent build since 2013 and nothing has broke. I'm afraid I've lost touch with what's the latest-and-greatest. 1) I want to do another build, this time an "assist" based build, the lightest possible motor...

Seems like an "escalation of force" problem. I mean sure you can upgrade the motor, but then you should probably upgrade the axles and then you probably don't want that much stress on the wheels/tires so upgrade that too, then the brakes won't stop you fast enough, then the ball joints ect ect...

18650 cells dont put out much current nd are fairly heavy.... so dont expect too much performance from them Right. For typical 5 minute "sporty" flights I like a good 30-40c, for 30 minute flights I want about 10c and for 1+ hours flights I only need 5c. For my intended use 3c is plenty fine. It wi...

I notice they didn't include you in the results listing:

Electric bikes were put into their own separate category which is fine with me.

yeah a good 20 minutes faster than the 2nd place rider lol, I just couldn't help myself. "You are going to burn up your battery trying to go faster than us on the hills" "your motor will break if you try to keep up" "you should start in the back so you don't interfere with the 'fast' riders" "you sh...

How big is the pack ? That's sounds good for a flashlight. Like 3s for 12v . Not a bouncing ebike. Sorry I was thinking 3s 10ah. I'm into both electric bicycles and model airplanes. It would be for a long-skinny fuselage. For model airplane weight reduction reasons I probably won't be doing a full-...

of course they weigh far less so all around a hub is a poor choice for weight Hey, that's not true BBS02 = 10lbs BBSHD = 13 lbs Cyclone kit = 16lbs. 9c/mxus hub = 13 lbs. The weight is comparable because a certain amount of magnet and copper is needed to accomplish the same task. 1. Cost: They are ...

I think I want to build a 2170 pack except stacked end to end like in a flashlight. What is the current best way to build packs like this?

Super american answer. I respect your opinion, but can't agree with it. In regards to America vs Europe it should be mentioned that American infrastructure is built up around highways and European infrastructure is built in regards to horse/foot travel only to later adapt motorized use. Americans c...

I'll be honest that is horse crap having a healthy respect for safety does not put me at risk that's idiot talk. I've covered hundred of thousands of miles and know all to well as I've seen the faces of death and literally just covered a bike ride where someone cut across a tram way and lost both t...

Well, you'll never get the full 100 watts. You can probably count on 70-80 watts under ideal conditions from a 100 watt panel.

Depends on the panel. I was pleasantly surprised to see my HQST 50w "flex panels" giving just a little more than 50 watts (measured at the wires)

I guess that sort of depends on how many whs you want to consume per day. I personally find myself creeping into the 2k per day mark at times. You won't get a full 100 watts out of that trailer during the morning and evening which is probably the time you want to charge. I would expect maybe 40-50w ...

The bike will "porpoise" if your shocks are too soft. You don't want to be leaning way forward after your wheel drops down deep in a dip. The bike will slam and try drive a bike up your innards/through your forearms if the shocks are too hard. Generally you want the shocks soft for casual use and wh...

Due to their more robust frame downhill and freeride bikes make the best bikes for what you are talking about. You can probably find a used one on Craigslist. You could put a large hub motor on the rear wheel but having single-tracked on both hub and mid-drive I find mid-drive to be better. Having m...

Ok,
I will play nice.

Ok, I have done several test runs of the Skull Valley Loop with the Black Bullet now. With 17lbs of lithium I'm hitting around 2:30 With 24lbs of lithium I'm hitting around 2:15 With 26lbs of lithium I'm getting just under two hours I guess the question now is should I leave the athletes in the dust...

Nice one DrkAngel! I did one using cement blocks too. I made the mistake of buying most of my blocks from Lowes. It turns out I have a place in my area that specializes in nothing but cement blocks (Yavapai Block) and sells cement blocks for much cheaper. My garden isn't really working for me. My is...

Presumably you just try them out and see what works best and this is because of impedance. Even among the same manufacturer antenna length varies and that's because loads are different from device to device. The materials used cause resistance and the antenna/device has to match. For instance when y...

Awesome! Glad to see in the details that it's a relaxed group ride, otherwise I bet people would get their feathers ruffled at the motor. I dunno, there may be some "feather ruffling". On 8/14/2019 the website said it was an electric-bike friendly event. After I registered on 8/15/2019 and mentione...

The Black Bullet is going to the SVL Challenge (https://www.svlchallenge.com/)
