Re: Vsett 10+ - battery and controller upgrade

The motors I've opened up have nothing inside that could be characterized as "electronics" besides three Hall effect sensors. (Those are on a separate 5V bus.) Everything else is big copper, magnets, back iron, bearings, and structural components. What part of a motor exactly are you sugg...

Motorcycle touring fairings typically increase drag, because they are designed to form a "bubble" for the rider that is larger in frontal area than the unfaired motorcycle and rider. Vetter Windjammer was definitely designed for rider protection/comfort and not aerodynamic improvements. L...

Re: Vsett 10+ - battery and controller upgrade

You physically can't have more than a handful of millivolts of "spike" because it would disappear into the motor or the battery. I am afraid it's way more than just "millivolts" of spikes. It's massive, sudden drop of voltage that will damage the motor. And I did not say the phy...

Most people can't adjust rim brakes let along caliper disc brakes.
An argument could be made that those people should stick with bicycles that have coaster brakes.
Plunger brakes also OK.

Re: Upgrade brakes and running shifter cable under Tongsheng mid drive motor

I have a new problem with my bike. While I was riding my left crank arm starting coming loose. I stopped and found that the crank was wobbly and the bolt had become undone. You've ruined the left crank arm and must replace it. Once ridden in a loose condition, the tapered hole becomes distorted and...

Re: Truing this Disc rotor is trying my patience

I like Spyke and Spyre brakes fine, and I don't think they're overkill. But I also don't find them to be better than BB7. My main quibble with them is that they require more frequent adjustment than BB7. To even compare Spyke and Spyre brakes to BB7 is absurd. BB7's basically suck. Extra adjustment...

Re: Truing this Disc rotor is trying my patience

Or you can put a pair of M6 washers under the caliper to raise it up a mm or so. Quite right. Believe the OP has a stack of washers for spacing. Eww. That's proof that he's using the wrong IS or post mount adapter, or else using an adapter than needs spherical adjusting washers but doesn't have them.

Btw, OP, you don't have to replace the rotor. Just file down the high spot with a flat file...file a little and test where you hear the high spot and when sound disappears, you are good.

Re: Vsett 10+ - battery and controller upgrade

I'm talking about the sudden voltage spikes/fluctuations in large level not electrical "noise". Not all controllers are perfect. They sometimes fail to deliver the stable/tolerable voltages. The internals of the controllers aren't designed to run dual motors when two controllers are used....

It sounds like your wheel is simply out of true, which is characteristic of lousy Chinese hub motor wheels with spokes that are too thick.

Re: Vsett 10+ - battery and controller upgrade

Dual controllers (not yours, but the dual controllers in general) will cause voltage spikes during load due to imbalance of the power delivery. From where are you pulling this nonsense? Controllers can make electrical noise , but all "spikes" (from constructive wave interference I guess?)...

Full suspension. Still figuring out the exact components but most likely a Fox / rockshox downhill front fork. I would not think that you would need a ' long travel' downhill fork unless you are planning on riding some very rough terrain. SF Bay area roads can get as knarly as some trails, maybe ev...

Re: Rize Liberty – What a mess for a $15.00 design oversight.

Regarding the damaged axle: Keep in mind that non-turn washers and torque arms are only one line of defense against motor reaction torque. Adequately tight axle nuts are pretty much equally important. Those are not the responsibility of the manufacturer, but rather that of the end user. I've seen mo...

Re: rear hub noise, looking for advice

Is there any movement or free play when you wiggle the wheel side to side?

If so, that would be strong evidence of bearing failure-- but note that such bearing failure can allow rotor magnets to rub against the stator laminations.
