He got the single speed version, so he'll either have to run the BBSHD as a single speed, or have to try to figure out how to add a hanger for the derailleur, relace rear rim for a new hub, add a shifter, etc. Brakes are pretty far down the line.
Keep it a single speed and you lose the benefits of a mid drive, while inheriting all the downside from stressing the drive train. For that frame, a better hub motor might be the preferred option.

I don't care if you're across the pond I will help you ?!? I'm going to give you my next door neighbor and he has links and everything to the 73 Mini-Me bike so as mini bike for you I'll see you tomorrow. too funny I know I'm right
The frame has flat dropouts, so this might work. Looks like its the slot has the right orientation for the frame dropouts.

Really? The ones I've dealt with were leaky. They were guaranteed against leaks and still under warranty, but nonetheless they were leaky.
WOW!
Seems to be a lot of negativity within the community so far. Reminds me of the PC gaming communities I once was a member of.
I went for the ZG as I didn’t want a geared version. So are you saying the BBSHD is rendered useless because the bike is single speed?

There are a variety of individuals on this forum with various priorities and opinions. You have not told us your reason for getting an E-Bike so individuals may project their own preferences.Shaun8281 said:

Personally I do not see the problem with a single speed. I hardly ever pedal anyway. Keeps things a lot simpler (i.e more reliable, less maintenance). What I do not understand is why replace the hub-motor with a mid drive. If you do not have transmission (i.e derailleur or IGH) then one has lost most of the advantage of a mid drive and made the machine more complex. The only advantage I see is the possible reduction in the rear unsprung weight.
Edit:
I think that you got the non-suspension version, so no advantage for unsprung weight.
Their web is terrible ... hard to pick out the various models.

No no no you bought the bike it's brand new you use it we all need a ebike and one to work on the one to ride this is the one you can ride every day always and will always work. That's what you have.
now this is what this form is for get another bike maybe a steel frame look for a time before you buy it where will the battery fit and where will the controller go .
Some people here might be offended you didn't ask us before you buy remember there's a lot of sensitive people on the forum. So treat some of the old big babies carefully.

Now with this new MID drive you need a new bicycle just put it on a second build. now, with this new frame in mid Drive let's see where we will place the battery and how big of a battery would be good for you as the battery is the heart of an electric bike.
Let's see if we get these people on board. So now you'll have one hub motor bike at 1 mid Drive motor bike.

Congrats on your first E-bike! Don't worry I'm new on here as well and right away noticed the same thing 
about sensitivities. Nonetheless this forum is great for learning!
My first E-Bike was a BBSHD I installed on a mountain bike with 7 gears. I agree with what others mentioned that you would benefit mostly from the Mid drive with gears.
You should take your time enjoying and getting comfortable riding your Super 73. Maybe you will be happy with the 73 the way it is or maybe you can learn to install a new rear wheel with a few gears to work with the BBSHD mid drive. If you end up with the BBSHD def install a gear shift sensor as well!

That's what he's saying.
There are benefits and drawbacks to a mid drive that goes through the bike's gears, but almost all the benefits are predicated in being able to change gears. If you only have one gear, you don't get most of the benefits, only the drawbacks. Those include fast wear, increased maintenance and downtime, no redundancy between pedal and motor drive, higher cost, reduced ground clearance, and increased Q factor (width across pedals).
The one single benefit that you would get from a BBSHD on a single speed is the ability to fine tune the gear ratio mechanically rather than changing the running speed electrically.
It isn't negativity to point these things out to you. You need to know them, ideally before you throw money at a project you don't understand. But at the very least you should know them before you throw even more money at it.
Maybe the sensitivity around negativity, vs being just accepting of facts is brought from the gaming forums? I hear kids are pretty brutal and do a lot of bullying nowadays. For me, admittedly I don't have the best bedside manner or take time to pacify people, while others are great at that. I pretty much presented the same thing everyone else is saying, including some solutions to make it work, but making the wrong purchase is a tough pill to swallow, but in the end it's your money, so time to move forward with what you got.Chalo said:
The entire purpose of a mid drive is to use the gears to climb hills, you dont need many gears for that either just to have a big gear for the climb, an option for you is to use a rear integrated hub if the agreement is they can hold up. Some igh you can pick up for cheap because they have been around for so long, I personally have a 1976 Sturmey Archer 3 speed with a range from 75% - 1:1 - 125% but there are newer and more expensive ones with a wider range.
But what you should do is just hook it up as single speed and ride all the steep terrain you will ride and see, then sell it or keep it.
btw if someones feelings in general, not specific are truly hurt by literally anything said/typed online then I do not know what to say.
I would say turn off all devices, log off and get out into nature and join a club, www.meetup.com is great for meeting new people and joining a club of similarly minded people. I really dont care either way if jokes come across or not in textual format, it was quite a bland joke because I went easy on the new guy trying to have a welcoming atmosphere, and he didnt seem to upset over it but confused over the insider joke. I did not realize this forum was a safe space, do we now have to come up with personal pronouns and have to use them for now on? For myself I have always liked "Bossman" or "Big Guy" which have always been nicknames from strangers for my great presence and handsomely good looks. But yeah we can switch the nickname to personal pronouns which seems to be the new rage, and it took me forever to try and figure it out because I thought people who used he/him or she/her on zoom were gay but the amount of people using the pronouns seemed to be quite high and most did not look gay, whatever that means but you know what I mean.
God damn I went on to long with that, sometimes I just get rolling. Nows the time to trim as I have not submitted the post yet.
Everyone makes mistakes when we first get into the ebiking hobby, the super73 seems to be popular that I hope you live in a high population metropolitan city that you can sell your super73 single speed and buy a multi speed super73.
Aside from my joke about super73's I would get one for roaming the campgrounds but I still think a regular bicycle would always be better.
To each their own.

Pedaling or non-pedaling would be a good piece of info. Based on forum posts, the BBSHD is happiest spinning faster, so small chainring up front, large cogs out back. If you want to contribute by pedaling, you usually want the opposite.
Using YouTube videos as one reference, you can see what gearing provides the highest speed (which is never high gear) and design a single speed around that gear ratio, and accept only pedaling to slower speeds.

Shaun,
I am still a newbie here and I enjoy and occasional kick in the back, kick comes from a heart of good intentions. I rather hear all the criticism and raves and then make a decision than, keep stumbling myself.
If you look at the post history, most guys here have done IT, and done IT well many many years before we even knew what an ebike was.

OP is interested purely in single speed and also wants better brakes.
So I am guessing he wants an increase in top speed.
How much faster does he want to go?
P.S. The zg version of the Super 73 is a 250 watt EU version with pedal assist only (up to 15.5 mph) from the geared hub. No throttle.

… and that’s why I’m changing from the OE 250w with no throttle or display.
It’s totally flat round here it won’t be going off road etc. I just wanted the best mid drive I could get hold of and the BBSHD seemed the right choice.
People have thrown the lack of gears at me but I didn’t think it’d be an issue as like I say the bike is staying on flat ground.

But that means a hub motor can do exactly the same job with less wear and tear, less expense, better packaging, and single fault tolerance.

You don't have to change out the hub motor.
1. You could keep it and just upgrade the controller to one that will handle more amps and is also compatible with a throttle and display. Unfortunately you will likely have to upgrade the battery depending on how many extra amps you want.
2. You could keep the hub, factory controller and battery and just add a separate throttle based system like the BBSHD (or a left side drive like Lightning Rods) with its own controller, battery and display.
How many volts is the existing system? (edit: I found the answer. It's 36 volts)
How fast do you want to go? (I am referring to top speed)
