I think the main reasons for the Chinese ebikes and components to be cheap as you see are: 1. A huge market with dramatic competitions to lever the quality while to lower the price. It's easy to understand, no need to explain more. 2. Clustered manufacturers for all components in one place. For...

Ok, after a few days of riding, the joint part seems to have been filled with the black materials from the brake pads. I haven't gotten a chance to take further action to make the sharp edges smoother. But this filled up material might be helpful to reduce the future threatening to the brake...

You know what? I just ended up making one of the click-stand last night with a poster tube! It worked pretty well. Since I am going to use it only in the garage and hence I am not worried about being stolen or something like that. The tube is pretty and thick and strong, and I can make a groove...

You know ebike is heavy with batteries put on a pannier side (only in one pocket). Then I found this click-stand: http://www.click-stand.com/not-your-typical-bike.html which is just a stick! I thought I can make it on my own for free, but, wait a minute, is it stable enough for holding the ebike...

I am putting 30-40 psi on the rear tube in the past month, and it works well for me. Especially because my rim's joint was hit on the curb and resulting with sharp edges, I am also lowering the front wheel pressure now.

Those edges might be caused by my hitting on the road curb the other day. I was totally rolled over the bar under a high speed, and the tube was exploded right around the rim joint position. I would like to find a way to smooth the sharp edges. Filing the ridge doesn't seem to be a great idea to...

Ok, I indeed found this type of joint on my rear rim, although it's tightly joint. Thank you for pointing this out!

Interesting to see this! Does every double-well wheel rim have this type of joint? I didn't notice this before, and no idea how would this impact my daily usage...

Cracked rim https://imgur.com/gallery/9BHx1 Here is the photo. Sorry, it's too big to upload at the beginning. I feel it's ok still and put a plastic board between the rim and the tube to cover the sharp edges, but not sure if it worth me some hard work to disassembly spokes and redo them (no...

I hit on a rim on the margin area of a road to avoid a car blocking the way, but I fell over the bar of the bike and the front tire got exploded. In my further check, the double-well rim of the front wheel got cracked yet everything else works fine. The front wheel is the 26in motor wheel and...

Interesting data that the tire pressure doesn't affect the speed that much!

I will search for it. Thanks.

The voltage on one end seems too high for me. Don't worry about the other one which is not connected and shouldn't have any read. You can test it by quickly short the two wires with an ampere meter connected and the motor on. If the current is small compared to the motor, very likely you can...

Good point! Thanks.

Wow! That looks a little crazy :) I can never reach that far in one shot.
