Some words about my Abrams:

First ride

https://u.pcloud.link/publink/show?code=XZAy7LVZyR4BwbwK8fLSewl2s8lUJYBxbvSk

Custom pedals. collapsible stand with adjustable pedal mounting height. in this version +55 mm relative to the factory position in order to make the knees comfortable.
The rack mounting screws are recessed into the racks and do not interfere with removing the motor from the arch.
When folding, the pedal rests on the rack, and not on the battery. Thus, there is no damage to the battery and it is protected from external influences.

The support bracket is cut from a single piece of aluminum plate. Thickness increased to 6 mm. The width of the bracket is also increased.
In the factory version, the bracket is thin 4 mm and fragile, as it is cast in silumin alloy.

In the photo below we see what I was talking about above - custom racks, custom brackets, rack mounting screws recessed into the racks. The edge of the arch is glued with noise insulation to reduce vibrations and reduce the penetration of dirt from the side of the tire.
The stock handle has been removed. A metal-plastic water pipe was used as a handle. the ends of the pipe are filled with polymorphus from the inside. The fastening of the pipe to the bracket is made with self-tapping screws that pass through the pipe and polymorphus.
As you can see in the photo, the rim has been repaired. A tubeless tire releases air when it deforms. The rim of the wheel, hitting an obstacle, cracks.

A camera has been installed to avoid such a situation. For convenient pumping, a 135 degree adapter with aliexpress is used. Its weight is 15 grams. On the opposite side, a balancing weight of 15 grams is glued to the rim.

Extra details sawed off. Extremely poor wheel design. Flimsy support bracket, M4 screws securing the controller, which rips off on impact. and the frame in the mudguard area. Imagine that your wheel is somersaulting and hooked on this ledge. The huge mass of the wheel breaks the structure.

The wheel should be protected with an egg-shaped outer contour of the protection so that in the event of an impact, the load is evenly distributed over the attachment points. The new transport handle made of 20 mm multilayer pipe is already used as a load-bearing element. Provides protection for the controller, headlights. Yes, of course the headlight and taillight are sealed. The splash guard is cut out of a plastic kitchen board. The coloring is ambiguous, but it protects perfectly from splashes. And the mudguard doesn't break. I bought a set of three plastic cutting boards for the kitchen at the home improvement store for three bucks.

Thanks You, I edit the message and paste links to the pictures.

Unfortunately, I did not find the option to upload photos to the forum, only the option "Insert image from URL"

You can only upload pictures from your PC to the forum. But your pictures are online already, and it's better to use an image host anyways. The forum is not meant for storing much data.

@spb I'm curious about your pedals and hangars and rack. Did you manufacture them yourself?  I would love to get a set.  Does it lift the pedals up any higher?  

About pedals please write to @baihyaro in Telegram, hi is author. His name is Jaromir . Standart lift is 0 mm, +25 mm, + 45 mm. I asked for a 55mm pedal lift as I am small, 1,67 m.

For reinforced support brackets, please write @easynick in telegram. His name is Vladimir.

P.S we're under sanctions... mail seems to be still working.

P.S.2 I recommend to pay attention to the channel https://t.me/excera . the author plans to build a new frame for Abrams in July. The video from April has some interesting ideas. I'm thinking of redoing the handle attachment a bit in my version - not to small plates as in the photo in the post above, but I'm thinking of using a long strip of aluminum from one post to another, with two bends. Similar to the video https://t.me/excera/42, but without welding. I think to fix the same strip to the controller case through the corner with screws. there is a place. this will provide excellent rigidity of the position of the controller case . if I do, I will add new photos

Friends. I would also like to warn against driving while sitting. The brackets to which the arcs are screwed are weak and accumulate metal fatigue over time. Perhaps another bump will provoke a crack, which will lead to a fall. It should also be remembered that the controller case is attached with an intermediate fastener with M4 screws. This is a very weak connection. I saw in the photo the consequences of several falls and everywhere there is a destruction of the support bracket, thin screws securing the controller case. Therefore, I would not recommend riding while sitting until powerful bottom brackets are installed, and plates are not started up between the arcs, similar to the one here https://t.me/excera/253
 
And by the way! Did you know Abrams can fly? https://t.me/excera/259

So even seated is not recommended on that wheel?? Seated is the biggest positive point of the abrams, oh man.....

SPB has some nice mods to the Abrams. Looking forward to see the new chassis you have. Hopefully can accommodate double the battery?

Wow. Now that's a well loved wheel! Without the roll bars, the shell looks like a tombstone. Or a coffin. Maybe your next paint project?

The wheel is stylized under the game Half Life 2

I personally do not ride sitting, because I looked at what it all relies on and realized that the design is very flimsy and decided not to buy a seat. There is such a thing as "metal fatigue", so at one moment silumin can crack and fall apart. It is one thing when aluminum is cast at the plant, it has its own strength parameters, and another thing when small-scale production from silumin is underway.
when 10 kg from the battery hangs on supports on each side, and another thing is when another uncle weighing 100 kg sits on top, that is, 50 kg per side.

Sorry to bring back a long unused topic, but a couple of the vendors are starting to sell the abrams very cheap and I am wondering it the firmware update fixed the problems and I should pick one up? FreeMotion is selling them for $2400 which seems like a VERY good deal if the issues are fixed. Was there a problem with bearings as well or just the firmware?

No issues except being a cutout wheel abandoned by Leaperkim… even sub 2k$ is not worth it.

It depends on what kind of riding you want...

Its utility is limited. Abrams is tall and heavy and doesn't tolerate mud or debris. 
If you live on the ground floor and don't mind "lack of nimbleness" and don't need to ride offroad and don't need 3600wh... sure.

Or, your $2400 could go towards something that is sporty offroad, or has a cushy suspension, or is just easier to transport.

(I have a local with an Abrams, and after riding it my larger-battery knobby-tire Sherman felt small and nimble... and MSX weightless.)

They never fixed the cutout issues?

The Australian stock that I'm aware of never had the cutout issues as they had different hall effect sensors that were not as noisy electrically. Leaperkim's fixes for the cutouts for earlier stock in the US and Phillipines consisted of both the software (more tolerant to interruptions in hall sensor) and hardware (different hall sensor).

I was under the impression they did, but I don’t know for sure.

I was on the new firmware (had just updated it) and mine cut out giving me a hall error that eventually went away. I returned mine to ewheels. I wouldn't recommend getting one even for that price I liked the ride but it's just not worth gambling on

Well...after going back and forth for a long time and still having no definitive update on the V13, I pull the trigger on an Abrams from EEVEE's. They have them seriously discounted with new tire, rim, motor and firmware. I still want a V13 in the future, but from what I understand this should solve any unwarranted cutouts. I will update if I notice anything.

Would be great to hear your first impressions, riding experiences, etc. It's been a while we haven't talked about Abrams here... :-)
