Re: Purpose of the white stripe on Schwalbe tires?

The link looks to be for Schwalbe Smart Sam- Performance Tire/Addix compound. So the white stripe may be a way to identify this tire easily from the other choices of tire construction / application. https://www.schwalbe.com/en/offroad-reader/smart-sam.html Looks like you have to click on performanc...

Re: Purpose of the white stripe on Schwalbe tires?

Many Schwalbe tires are made with a reflective stripe. I don’t know about this one but if it is, you will see it specified on Schwalbe website.

Re: The fastest hub motor for a bicycle when moneys not an issue

Yep. Back then when this thread was posted, it was uncommon to build bikes that were doing 80 Mph. Many are doing it now, much lighter, and handling much better than this beast. Still, it is a nice build, in its style. Welcome on ES :bigthumb:

Re: Where are the hq geared hub motors?

Interesting find - but 5.2Kg! WTF - that's more than some DD motors out there known to be able to handle 1000W. Going to ask heinzmann about more details. A better hub is a heavier hub, mostly. Lucky you care about gears and bearing and construction quality. If you would care about power and speed,...

Re: Solid tires?

Re: Anyone modify a 3 wheel HONDA GYRO to electric ?

I never saw one mod as an EV.
I find it an interesting project.
I would build it with 2 rear hubs. I don’t know how the Gyro is built on the rear, but I guess it wouldn’t be so hard to do. I saw one riding and it does look like a good ride, with the potential for a great leaning cargo trike build.

Not very practical, unless you have many that are the same and don’t bother the room required to mount them on a bike. One won’t give any interesting speed nor range. I’d say 6 of them are required at least. It is much better to strip them apart and to build a battery from the salvaged cells. It wou...

Re: Looking for an alternative to 24x3.0 Duro Wildlife Leopard

The 24 X 3.0 Berm Master is not good for dirt, other than nice hard pack. On the street it does very good on a wide rim, low PSI. Eastgem in China, has a 2kg 24 X 3 street tire that I would like to try. http://www.eastgem.net/tire-24x3.html http://www.eastgem.net/images/acc-page-tire-008.jpg?crc=13...

Re: regenerative braking in winter

I have been using regen braking every winter, down to -20. I use regen only in the winter, because slippery conditions are making it useful, and because I lower the power of my bike during the winter. In the summer, when my bike is set full power, regen does kick too hard and I prefer the brake. My ...

Re: Solid tires?

Yep. A bicycle tire, even a tough 2 ply 3.0 with a thick DH tube, is still the light weight option for a reliable ebike. A Cush Core insert does add little weight for it is not much heavier than a 3.0 DH tube. But yes, the Slime does slow down acceleration, if you fill a lot of it especially. 6 oz i...

Yep. Cush Core inserts are wonderful for ride quality and flat protection. For me, the only downside is the hassle of tire replacement, because I am wearing them tires fast and the job of replacing one that is tubeless with insert is PITA. I now can make them foam inserts cheaper and easier than Cus...

Re: Is it safe to leave ebikes parked in extreme sun

RC lipo disposal Slowly drain them to 0v, leaving them plugged on a light (for an example). No matter the resistance that you are using to discharge them, it must draw low enough current to keep them cool during discharge. Once all the cells are at 0v, they are inert and safe to send to recycling fa...

Re: Newbies First Build - 3000w Cyclone w/ 72v battery?!

Your bike is OK. You can build on that frame, lots of speed and power. If it is a large, even better because a long wheel base does help a lot stabilizing at high speed, and temper the effect of hard acceleration. Like I said previously, you will have to make compromises. Reliability and speed are p...

Re: ATE 501 batteries

Since you don’t seem to have any means to measure current draw, we can only guess. I suppose that your system does pull more current than it was used to. There are many possible causes for that: mechanical resistance (brakes rubbing, etc), current loss (wiring, connections, etc)... or there could be...
