Damien, I looked up the Hyper Bike Beach Cruiser, it didn't look much like yours. Such as the front and rear wheels with disc brakes. Tell us more about your customizing, and fitting the rear drive sprocket, etc!
See the link to this below...I did change out the spoke wheels to mag wheels to accomodate disk brakes to get rid of the coaster brakes...The before and after pics in the link will show you why it looks different...(Basically, the only thing that is left over as Hyper, is the frame and front fork, and the crank and pedals and handlebars...lol.)
This post will serve almost like a tutorial as to how I built my bike, parts used, where to get them, what I needed to do to adapt things to actually fit and work together...Follow all the links including links within the links to get the full story of how mine was done so that you can also do this, or something like this, for yourself as well.
Hi guys, Well its been three weeks now from start to finish but the conversion is now complete from spoke rims and rear coaster brake and front rim type brake, to mag wheels and disk brakes. Had to make the rear brake caliper adaptor from military aircraft aluminum, (the kit ones just would...

These are the ONLY tires and tubes I will use with these mags, they are rugged and haven't had a flat or even a slow leak in 7 or 8 years now even when I was still using regular spoked rims which I ditched because coaster brakes is mayhem or death looking for a place to happen with these motorised bikes.

Also the link below this will show you the mags and where i got them from...They come with the disks, calipers, disk brake pads, 36 tooth sprocket. and the spacer needed between the rear disk and drive sprocket...
IMPORTANT: Be sure to order them with the 36 tooth sprocket to avoid clearance issues with the caliper and chain and rear drive sprocket.
This is where I get my 3 spoke mag rims:
Are you looking for a heavy-duty wheel set built for speed? Sick of having to make constant adjustments and to your spoked rim? Then the BBR Tuning 26 Inch Heavy Duty 3 Spoke Motorized Bike Mag Wheel Set is exactly what you’ve been looking for! Built to be disc-brake ready and pre-installed with...

I don't recommend this method on an aluminum frame because it would probably crack and break, but this is what i did on my Steel Frame Hyper Beach Cruiser to accomodate the rear sprocket and disk to fit within the dropouts and frame.
On my bike, (steel frame ONLY), i had to "stretch" the rear forks apart by hand, about 1/2 an inch to put the rear wheel with sprocket/rotor attached, and then use a spare 15MM axle nut on the sprocket/rotor inside of the drop down, threaded to the axle with blue locktite, to maintain that amount of "stretch" to accommodate the amount of of clearance space the rotor needs so as not to be pressed against the frame.
It helps to have a buddy with a strong pair of hands to help in this proceedure like I did...lol.
EDIT Monday, July 10th, 2023:
This link below will show you how to make a frame stretcher tool for spreading the rear of the frame if your going to use mag rims with disk brakes on your bike.....Beware, do NOT attempt stretching aluminum frames as they will crack and break.
It’s nice to have an unusually strong friend around to help you stretch out the rear frame for modified rear wheel accommodation.

And this link showing pics of how it is used to stretch the frame.

You will also need a freewheel sprocket for the pedal chain side of things as well and will probably need to add chain links to the pedal side as well since the freewheel is larger than the stock coaster brake pedal sprocket.

Ps...I also eliminated having to use a chain tensioner by cutting the drive side chain down to custom fit like a motorcycle chain when i also did the pedal side chain sizing so they are now both custom fit for the bike.
A pair of these adaptors (2), one for the front, one for the rear, will also be necessary, or something like them since you may or may not be able to make your own frame to disk caliper adaptors as i have done.
This works with motorized or standard bicycles and allows you to install a disk brake if you don't have the necessary mounts. No more rim or coaster brakes.

And a dual brake lever for the disk brakes since you already have the clutch lever taking up real estate on the left side of the handle bars...lol...also on sale for 10 bucks for the next 16 hours....You will need brake cables from your local bicycle shop as well to connect the brakes.

These are the fenders i used to replace the metal stock fenders since they break off due to speed and vibration and will cause you to have an accident or worse.

This is what i used to replace the kick stand with.

And this is almost like the front engine mount that i had made for my bike and should work perfectly for yours since i do not like the ubolt type front mount that comes with the motor kits.

I also used the Zeda 80 motor for my bike build.
EDIT:, It now has the Phantom 85 on the bike.

I hope all of this is helpful to you...lol...DAMIEN
Ps...This link will also show you the links to the exact tires and tubes i am using...Cheap stock tires have never lasted more than a few days for me due to mesquite thorns and goat heads here in the high desert.
Damien, can I ask you what size tires you're using on these mag wheels? As I'm really interested in them (thanks to you posting them!). I'd like to use 26 x 2.125 at a minimum. I'm thinking of converting my Huffy over to this during the winter months. Here are the links to both the Kevlar tires...

Also a link to proper tire inflation for the tires i recommend as well the seat i use and the reason why for both recommendations.

EDIT...Be sure to replace the stock intake and exhaust gaskets as they are Chinese crap that will leak.
NOTE...The gasket recommendation DOES NOT APPLY to the Phantom 85 motor, they are OK as they are.
For the exhaust gasket, you want this one listed below in the link.
(Except for the Phantom 85, it won't fit so just use the stock one that comes with it as it is a fairly decent exhaust gasket)

EDIT, 3-17-2023...This is the seat I am now using that has replaced the one that you presently see in my pics of my bike...It is even more comfy and springy than the last Schwinn seat I was using for years.
My own personal bike building motto:
"It is one thing to just strap a motor on a bicycle and expect it to work, It is quite another thing to carefully and methodically and mathematically build a motorised bicycle that actually DOES work"...DAMIEN
