Serial 1 Modifications / Re: Raising the handlebars
« on: March 07, 2022, 09:13:16 PM »
Almost a year later, I went back to the Harley dealer. This time they let me take off the stem cover and take a look.

As you can see from the attached photos, the front portion of the big square stem is the actual stem, and the rear portion is the top cap. You can easily remove the hex bolt and top cap. Underneath, you can see a standard 1 1/8" threadless stem, which also has a standard 31.8mm grip for handlebars.

So this is all standard stuff, and you can replace the stem and handlebar at will, right? Well, you could...except for the cables. It appears that the power/control cable(s) and the rear brake cable run just in front of the stem, protected by that big square cover. They go all the way to the front of the stem, and straight in to a hole in the handlebars. Worse, one cable (which I assume is for the front brake) goes straight up through the stem itself.

So to change anything, you'd at least have to bleed, disconnect, and unthread the hydraulic brake lines. And the power/control lines for the headlight and control pad. Then if you raise the handlebars, I suspect (?) the lines will no longer you'd have to replace them. You can buy a length of brake line, cut it to size, and run them outside the frame like most bikes, but I am less sure about replacing the lines to the headlight and control pad.

Mind you, at least it is possible! I am not at all sure that I want to take on this kind of headache, though.

Great, thanks for posting that here. Yeah, I see that on page 25 of the US owner's manual (at

The word "may" doesn't give me enough confidence to buy one, but it does give me enough hope that I'm going to keep checking back at the site. In fact I think I'll email Serial 1 support and ask again. I asked before, but they didn't have any info then.

I mostly gave up and bought a Pedego Conveyor. Same general "low-maintenance commuter" vibe with belt drive and sealed gears, same tire width, same MSRP. It's not as nice as the Rush/Cty Speed I had my eye on - it's class 1 instead of Class 3, 468Wh instead of 709Wh, and ~300% gearing range (Alfine 8 hub) instead of ~400%. I would have far preferred the Serial 1 if it fit, but I was easily able to modify the Conveyor's standard handlebars and stem so I can ride in comfort, and it was 1/3 off. It's not amazing, but it does what I need.

I could sell the Conveyor or relegate it to "daily fitness bike" status if I'm ever confident I could get the Serial 1 to fit me properly.

General Chat / The floppy little charge port cover

I love the Serial 1 - design, components, build, quality...

...but boy, does that floppy little rubber charge port cover seem out of place. It's easy to enough to remove; just tug on it. But putting it back seems to be a real pain. Is it just me? Is there a trick to it? I can get it, but I have to futz with it a bit.

MOSH/CTY / Re: Serial 1 MOSH/CTY Gear Ratio
« on: April 01, 2021, 08:15:55 PM »
Just for comparison, that's a 2.27 ratio. My Class 1 Specialized mountain bike with a similar Brose motor has 9 gears, ranging from 2.9 to 0.7.

Even though I live in a hilly area and my knees are shot, I very rarely use the lowest gear on my bike, and even the second lowest isn't very common. So it sounds like that ratio could be fine for me when taking off and going uphill.

But on level ground I'm normally in 7th gear, and as soon as I start downhill I am always in 9th and wishing I had more gears. I have a hard time imagining the speed your legs would have to be spinning to go 20mph or more with a gear ratio 3x higher.

But these are just numbers, and could be wrong. I haven't ridden the Mosh. A post from someone that has ridden it would be much more helpful!

General Chat / Re: Handlebar diameter and seat post?
« on: April 01, 2021, 08:00:55 PM »
I took the seat post out of a Serial 1 today. To my dismay, it was not the 30.9 that my current e-bikes use, so I couldn't plug in my suspension post and seat.

But I did have a tape measure. It looked to be about 1 and 1/16th inch, which is about 27mm. According to Wikipedia, "The most common size is 27.2 mm (1.07 in) for most bikes, especially for the higher-quality models".

You can also email Serial 1 support ( I have found them to be extremely helpful.

I don't think any dealers have the Speed yet, but maybe someone here attended one of the test-ride events a few months ago.

The Rush and Rush Speed do have slightly different motors, but Brose claims that the torque is the same. Well, the peak torque is the same - I didn't see a torque curve anywhere.

I haven't ordered a Serial 1 yet, but I have a similar Brose Mag 90nm motor on my Class 1 Specialized bike, and while torque is always best at low speeds, it's still got quite a bit at 20. I would think it would be fine...but then, I'm 100lbs lighter. I hope it works for you; please let us know once you have it.

The local dealer said "Serial 1 said they sent us a manual, but we can't find one, in print or electronic."

But I contacted Serial 1 service. They confirmed that the handlebars and stem are both custom, due to the cable routing, and are not meant to be replaced. So you have to find one that already fits you.

At least he sent me the geometry figures, so if you sit on one size, you can see how different the next size would be. I also noted that despite the different-looking frame and tires, the Mosh and Rush (and the step-through, for that matter) both have the same sizes aside from standover height. So you can try a different model, if it's in a size you are interested in. My dealer has a small Step-through, a medium and an XL Mosh, and a large Rush - that might be a standard "dealer kit".

I dunno if the formatting of this table will come through, here goes:

Size/Model   Size   Stand Over Height (50mm in front of saddle)   Stack   Reach   Wheelbase   Handle bar Width (mm)
RUSH/CTY   Small   686.5   575   384   1101.8   630
RUSH/CTY   Medium   713.5   630   405   1145.1   630
RUSH/CTY   Large   758.3   660   414   1166.2   670
RUSH/CTY   XL   795.6   690   438   1202.3   670
RUSH/CTY STEP-THRU   Small   448.6   575   384   1101.8   630
RUSH/CTY STEP-THRU   Medium   448.6   630   405   1145.1   630
RUSH/CTY STEP-THRU   Large   448.6   660   414   1166.2   670

MOSH/CTY   Large   720.5   660   414   1166.2   670

Serial 1 Modifications / Re: Suspended Seatpost

I know many people swear by the Cane Creek Thudbuster, but I had one and didn't think it did much. I did make sure I was using the proper insert for my weight.

I now have a Kinect 2.1. I love that thing - I will never buy another suspension bike. They are pricey, but I ride every day and comfort is important. Selle Anatomica sometimes has them on sale for 25% off, which helps a lot.

I have seen a few reviews saying the Kinect is the best available. Although one review preferred the Thudbuster, and one slightly preferred...dang, I forgot. Something else.

Serial 1 Modifications / Raising the handlebars
« on: March 31, 2021, 04:04:43 PM »
My joints can't take daily riding in the "typical" efficient biking position. I have to sit fairly upright.

On my last two e-bikes, I have replaced the stem AND the handlebars, for a total of 4" of extra height. However, the Serial 1 handlebars have the brake lines routed inside them, and the stem looks non-standard - very large and square. Perhaps I was just looking at a stem cover? I can't find a manual online, and the assembly videos show that the handlebars and stem come pre-attached to the bike.

I went to the local Harley dealer, and they say they don't have a manual yet, printed or online. They also didn't want to take apart the stem for me to look at. I did note that the handlebars are higher than the seat; probably because this is more cruiser/commuter oriented. My last two bikes were mountain bikes where the handlebars seemed to be at the same level at the seat. So maybe I won't need to raise the handlebars...but it's hard to tell, especially since the shop didn't have the bike in my size.

Does anyone have access to a manual, or a bike you can examine the stem with? Thanks!
