I ended up taking the bike to a shop and they ended up adding another spacer on top to better get things tightened down which eliminated the slop/wiggle at the headset.

Anyone know the brand/model of the rear rack on the UCP pro? Mine just had the aluminum of one of the braces break at the welds. While I am not pleased, I am not sure how to find another compatible rack, buying the same seems like the easiest fix.

Anyone know the UC Pro headset bearing sizes? The top says 1 1/8 but it seems like the top and bottom bearings/cups might be different sizes looking at the frame. I hope that a new set will fix the wobbly front, after an head on accident, which I cannot seem to get right.

I have a new motor, purchased 2023. I did not check the number of teeth on the gear, so I do not know if I have have the 15 tooth version. I also greased it with cornhead. It is tons quieter as I said, but I had not greased my old motor with cornhead, so it is hard to compare. I have noticed...

Any thoughts on it vs corn head (temperature, datasheet performance)? I put corn head in my new motor as I saw that listed in the forum. Did not pack it super tight as someone criticized another poster for doing that (though I am slightly worried not packing will allow the grease to be flung...

Got the new motor mount, works. So I am guessing it was the control board that failed on the old motor after all. I have a new control board I will put on the old motor and test at some point.

Well I finally have the motor disassembled, it was nearly impossible to get the that 16 tooth ring off and I ordered a terrible new tool for it. Disappointingly I can see nothing wrong with the controller boards, so now I have no idea what could be possibly wrong. I have not noticed any loose...

I did more testing, and while the motor does turn over with the use of the throttle, it is very very weak. Changing assist levels does nothing. I am guessing more than the torque sensor has gone wrong. Otherwise spent the weekend on house electrical work so I have (STILL) not yet dropped and...

Oh man! I did not see that the bolts have nuts under a cover on the left side! I just loosened from the right side, I bet its just the nut spinning, that is exciting.

First bolt I tried to remove to drop motor snapped. Any tips on how to prevent this? Any tips on fixing? (not sure where it is broken at this point)

GBK is frustrating me because their website was not working. I finally got it to work and selected fast shipping and now they say they are on holiday and will not ship for more than a week. Entirely defeating the point to paying for speeding shipping

Thanks, that is good to know. I am frustrated with the very very long delivery times for parts. Pretty inconvenient for a main method of transportation. Makes more sense now that some of you have multiple motors.

My Bafang m620 52v just failed, around 6180 miles. It just stopped providing assist on a hill, the motor make faint sounds like its starting up when I pedal but nothing more. I did find that walk mode works and when I got home an attached it the throttle works. The speedo work and turning the...

Handling is something to keep in mind, though I am not sure how much it plays into things with lower speed less experienced riders. I certainly have noticed that on step though frames the feel of the bike tends to beach cruiser, hates high speed and manuvering. I found that to be unnerving. In...

No idea about the Dominion's, but I am satisfied with the mt5s. I do have two minor gripes, I think the pads are heavily overpriced, best price I could get them for was 33 for a single set. That near car brake pad price, seems a bit much to me. Other thing is that I have noticed that towards...

I have taken it off a couple of times. It's a a bit of a bear, particularly getting it back on as getting everything lined up is a challenge with how heavy the bike is, still wouldn't hire it out, it's a good thing to know how to do. I recommend an assistant or having a stand that allows...

Done

This all makes me a bit sad and wish I had this magical new controller! Glad to see progress though!

So I don't really understand the strong feelings some here seem to have around wanting a full suspension bike, at least for a commuter. Mountain bike I can understand, but I can't see taking something this heavy out to do any real mountain biking unless it's being used as an extremely low range...

That would be sad, I like the design of the current UCP (which I own) much more.
