New Veteran "Abrams" 22-inch Wheel

Wow, this sound certainly different than the typical sinewave (or FOC?) EUC controller.

Can someone explain why the motor sounds like it's driven by a squarewave controller when accelerating?
Is that a way to push more phase current into the motor with the same components, even if it's at the expense of efficiency?

[meepmeepmayer]

I wonder if that sound might become very annoying very quickly. Unless you just don't hear it in the wind noise.

[That Guy]

My first impression, Afeez liked to push it to the higher speed (compared to his more gentle first try of the Commander). Maybe I just “see things”. :-) But maybe it is because Abrams does have a lot of torque. 
The motor sounds different, maybe because of a different way it is winded?..

[Mango]

This is what a torque tuned 3500 watt motor sounds like. Deal with it! 

[That Guy]

Curious to see whether the rather "undersold" Abrams and not the potentially "overhyped" S20 will be the next season sensation.

Please have more than 60km range at 40kmh.

My RS has somewhere around 60km range at around 30 - 40kph speed with its 1,800Wh battery, I really can't see the 2,700Wh battery on the Abrams getting less than 60km range if you keep the wheel at speeds up to 40kph.

Currently I'm trying not to go spending all my money on stuff I don't really need and I certainly don't need another PEV.  Mind you, if I sold my e-scooter and maybe (but probably not) my RS . . . 

I'm interested in the 22" wheel (more stable), the 3500W motor with lots of torque, not being slower than the Sherman, the IP65 rating, 2700Wh battery.  The high weight is a bit of a negative, but still . . . 

I'll wait for some review videos, but this wheel really does have me tempted.

i agree, i had a monster in the past and i still love the 22inch street performance, i always dream an upgrade of the v3 to 2700wh and finally we have the option...but...44kg is something to deal with

[ specially considering the other wheels avaible right now ]

Yes 44kg is a no-go if you need to lift or carry the wheel (for most people)

Although I was initially carrying my Sherman up and down stairs now I got the technique to push/roll it up and down instead.
While I thought anything heavier would not be even be an option, I'm now revising my opinion here. The Abrams with a 22" tire could for for me.

However if you need to lift your wheel in and out a car trunk, that'll be tough.

i agree that lifting is the most important part but weight affect also performance/dinamic/inertia of a wheel, i know very well how an heavy wheel feels like

We’re going to have to start regarding these hyper wheels as one-wheeled motorcycles and focus less on their portability and weight. If weight is a concern, there are plenty of sub 25kg EUCs on the market from which to choose.

I understand that so far all EUCs are just one category. But I agree that very soon there will have to be different classes for these wheels. Just like there are classes for two-wheeled vehicles, mopeds, light motorcycles, motorcycles, e-bikes etc. These are not only for legal status but for performance and size as well. At the moment V5f/KS14/Mten3 are the same category as Monster and Abrams. They are clearly very different wheels for very different usage. 

I just hope there will be flagship high end wheels in the smaller categories also.

We could all just get some protein powder and see it as building extra muscles. 😂

I'm used to carrying my Sherman up two flights of stairs a lot but seriously 44kg, that's really too much for a wheel.

[EMA]

it's not only the 44kg itself, it's also related to the other wheels on the market with similar performance

In my experience, motors are loudest when they're operating near their maximum output.

I don't find the grunting noises reassuring at all- perhaps Afeez was already at the verge of overlean, during his lunges.

Lacking dynos, we'll have to wait for more heavy-aggressive-rider feedback, to find out where the limits really are.

[That Guy]

44kg is probably the inevitable price to pay for the combination of both performance and build quality. I am not saying Veteran actually made both happen in Abrams - will see the reviews and feedback soon. But if anyone wants to build a robust and high performing machine it may have to be heavy?… (And I do hope Abrams did it, so my only problem with it would be the weight.)

I wish the comments were more meaningful from these guys. We learnt so far only that Abrams looks and feels big, and maybe accelerates and breaks better then Sherman? :-)

[fbhb]

 

In the thumbnail/start of @Afeez Kay's video it is clear just how huge the Abrams is in comparison to the Sherman, so unsurprisingly the weight increase to 45kg is understandable although not a very welcome increase to many.

The very tall metal frame construction, alloy control board housing, that massive wheel/motor assembly just has to be more solidly built than the Sherman's traditional plastic shell construction, so it should All add up to a step forward/construction advancement hopefully!

Titanium framing could be an alternative but it would have a very limited market at $10k+... :-)

[Mango]

First look inside Abrams build quality

 

 

[That Guy]

Well, I think what Kevin was trying to say through all this horrible wind noise is that he liked it ("nimble" (really?), "fantastic machine")... :-)

95kph cut off though? Is it because the "learning mode" wasn't disabled?

From the build quality I picked three main negatives: plastic trolley handle holders, metal that will rust (and had some rust marks already if I understood right), and the battery connectors that are exposed to the water from the wheel and need to be further waterproofed. Plus some not very critical wood screws.

Also nice detail that the alarm speaker is integrated in the front light (so it actually could be heard when riding).

@fbhbI saw a blue material between the mosfet and the larger aluminum cast heat sink, can you take a close up picture of this ; I want to know if it’s blue silicone TIM or actually a proper Thermal pad of quality.

@houseofjob do you see this?

Ah. The inline connectors are not GX-series. Upgrades, nice.
