Re: simple ignition wire question

Is there supposed to be an ignition wire on the picture you posted? Is it labeled something else?

How large is that space and what frame is it?

It's definitely not a DH frame with that shock.
They still refer to it as a downhill bike, but it only has 150mm of rear travel (but that was decent a decade ago).

Re: 25$ 1500w controller wiring question

You'll probably just need to get a regular bicycle speedometer rather than go through the controller. The controller has no way of knowing what size wheel it's driving and what speed the bike is going, whereas your old controller had an ability to program in those parameters. EDIT: Welcome to the fo...

Re: 1st ebike. Yescomusa battery/controller options

The PAS on the KT controllers isn't bad if you work with what it provides. On mine, level 1 give about 250 watts of assist, so without contributing leg power, the bike will ride at 14.5 mph, so I like to pedal up from there to 17 mph. That way, if I ride 17 miles, I'm only using 14.5 miles worth of ...

Re: Diamondback OverDrive, the RidgeRunner

Good advice. I've noticed that I need more practice in technical sections using an ebike with respect to controlling the power. But I've also noticed that since the power is smoother than when pedaling hard, I'm not losing rear wheel traction or lifting the front wheel as much on a steep climbs. The...

Re: Diamondback OverDrive, the RidgeRunner

Same here, the last time I rode there. Everyone was pleasant, but I think it was a weekday. I think it’s the open space, so less sharing of the trail necessary. I may need to build a mid drive for some of the really steep hills though.

Re: Diamondback OverDrive, the RidgeRunner

The scenery from the photo album from your original build made me start mapping out a loop in my mind for my a future ride. Up the hill, drop down through the Tilden Park entrance, up the trail to Inspiration Point, then ride ridgeline and exit out the west side by the Alvarado trail head. The nice ...

Here's an example of the derailleur mounted on a swingarm. This looks even odder since it would move back and forth too, not just up and down.

Re: 1st ebike. Yescomusa battery/controller options

Maybe it's the camera, but those dropouts look thicker than most steel dropouts. i'm guessing that if you're not using regen, you may not even need them running at 52 volts.

250w rated motor and 1000w controller.

all you should need to do, is use speed 2, on the three speed switch. You can use the full power occasionally, but keep the time you use it relatively short, like less than 20 min, and avoid the temptation to use it on really long, really steep hills. On the other hand, lower power controllers are ...

Re: Battery issue? :(

It sounds like you have a way to monitor pack voltage while riding, so you should be able to determine how many volts the pack sags via full throttle on a full charge. Re-reading the original post, I guess if the bike is run at full throttle, the voltage will keep sagging to 72 volts, where protect...

I'll take the disk brake pads off & order some new ones on ebay. I noticed the Q&A on Amazon has a question about the pads. One response mentions AHL brake pads.

I'm guessing so because the battery indicator on my display only has a 2/10 ticks off.
If it's dropping to 72 volts, which is empty, but the display is reading 85%, then it sounds like your display is faulty.

It would be good to describe the hills in more detail.
