Boy oh boy. Branching out to yet another design. Looks like an 7/8 spd to help keep the chain somewhat aligned. Probably the popular 197mm rear end. I wonder if they could offer it up with the rolhoff or kinderlay with a gates belt? They must be flush to pursue a new model that alot of folks...

Hmmm I wonder where you could find a skid plate for the Ultra motor?? Just get some Galvanized sheet metal about 1/8" thick or whatever mil thickness you can find and cut it out to I think it was 4" x 6", round off the edges, hammer it with a soft blow hammer across a 2x4, dont use the motor...

Yes you do need the separate 961 display with the software to access the programming file. Easy. Correct the Best tool programer will not work with this motor.

GBK has the UART style motors as a kit, bare bones or just the controller if thats all you need. Here's the 52v, 30a, 1000w UART controller I just got from them earlier this week.

In your opinion. Not mine. Why do you think I have a bike with a 1500w motor? It's to utilize that extra power for my benefit. If I wanted a bike to just give a little extra push I would of got a bike with a 250w motor. Maybe having some cut-outs would of possibly help keep the bike in check...

Started off on my first e bike and had the brake cut-outs. Quickly disliked how they would kill power if say for example climbing up a technical section and having to brake a bit to correct course and then NOT having that extra push made for some problems. Never have had an instance where I...

I started off on the e-bike journey like alot of you guys. Found out about the company up in El Sagundo and built up some bikes with the BBSHD motors. Great motor but you got to find the right frame to build up to make it worthwhile. Loved the motor and thought that as the the only way to go...

The Anderson power connection isn't the problem, in fact I replaced the pos and neg wires and have a male XT90 connector that is long enough to fit up inside the downtube which makes installing/uninstalling the motor alot easier. Like I said above the problem has not surfaced again. But if it...

Got 3 more rides in since my "issue" happened. So far all I have done is swap my 750C display for my 500 and all has been good. Still think it's a controller glitch but we'll see. Got my new controller today and it came already mounted inside the removable motor housing so if I ever need to use...

Controller showed up today and just an FYI to anyone else who orders one they come already mounted to the motor housing so no need to remove the old one on your existing motor, just split the case and unplug your phase leads and add a bit of grease if needed and your good to go. This one is UART...

Just ordered a spare UART controller from GBK and they still had UART bare bones motors for about 7 bills. Get em before their all gone.

Just odd that the issue went away right after showing up. Didn't crash or alter the wiring positions as far as I can tell. I will be swapping out the parts I listed above and we'll see how it goes.

The motor went into full power mode when I was off the bike as well as when I unplugged it. So I think that takes the throttle causing it out of the picture. It did it numerous times. Just turning on the display caused it to take off if it was in PAS 1, 2, 3, 4, or 5. In PAS 0 nothing. Turned...

Okay I have a head scratcher here. Purchased an Ultra motor (1000w) with the Archon X1 upgrade about two years ago. Modified some of the preset programable settings when I first recieved the unit right after building my bike up. All fine until yesterday, sort-of. I was climbing up a kinda...

I 2nd that advise about carbon fiber failure being sudden and swift. Back in the day ( early 90's ) I had my favorite crit bike that I always did well on and I discovered it had a small hairline crack back by the rear chain stay. Team mechanic said not to ride it but did I listen, no. Finish...

Me too. I was climbing up through a long kinda technical canyon to get to the top for the downhill drop on the other side. Three quarters of the way up it felt like I had a flat or the rear shock wasn't working correctly. So I dismounted and checked the tires and shock and they were all good so...

Nope I don't use the brake cut-off switches, got em capped off. Correct on the Mobil 28 being clay based.

If it's cosmetic why would he swap out the frame? Can you post up a pic?

loamoaf is this a WW bike with the Archon X1 controller? I have an Ultra motor with the Archon X1 upgrade and I am using the 500c display and it works perfect. Send me a PM and we can discuss online or by phone. Thats a better option than contacting WW if you want to get it squared away. Just...

Pretty sure you want the 150mm travel fork as opposed to the 110mm model. More travel better.... My guess is that you will have to go with the tapered steerer tube as the straight ones are not redially available from my experience. I think the Hydra has a tapered head tube as well. Worse case...
