They're just using a standard QS138 70H V3 with their own fluid for cooling. Nothing unique there. However the frame does not look familiar, so that might be something proprietary. Regardless, for that price, either do your own conversion (which is basically what this bike is), or just buy a Stark. Happy to see other companies trying, but today you either have to come in with something completely different or straight up more affordable in order to set yourself apart.

You're kidding, right? If this bike had been out when I bought my Varg, I probably wouldn't be on this forum right now.

Agreed on the full size bike.
You can buy a used Stark that's still in 1 year warranty (same as this) for that price. And the weight looks nice, but 4kWh and 41HP is only suitable for hardpack leisure MX riding. The battery being a quick swap is nice, but it being 4kWh low voltage one also means you will have to. If a 6.5kWh holds for about 30-45 minutes this won't do half of that (gross-nett gap and not draining to 0%). You might just get 15-25 minutes. After wich you have to swapp the battery, wich i'm pretty sure is not incluided in the price.
Also the low voltage battery will run quite high currentes to get 41HP, overheating will probably be an issue.

Add to that this runs FastAce suspension, wich Zero did too and now offers ZERO support for... Not comparable to Starks KYB that are top of the line and itterations have been on the market for decades at this point. It also doesn't run a linkage, do you think a budget suspension brand runs a proper PDS system?

I feel that in MX it will be a ''wives bike'' or an ''introduction bike''. The bike that ''tag along riders'' ride for it being cheap and simple to run and ride. And lets be honest, there is nothing wrong with that! Just get your aims right.

Their 50-65-85 line-up is a different story though. There are no real big competitors at the moment for the 85 class. Kids grow out of the 50/65 offered by the market and have to move to 85cc ICE's.

I do wish them best of luck though, they do sound like a passionate bunch, and passion always deserves a chance!

I've read the datasheet: 78 V, so they should have chosen their name better: HVR stands for High Voltage Racing.

One advantage of a bike like this compared to a conversion is that it has been done neatly from people who presumably have experience; the company may be new (I don't know) but the employees probably have expertise. I wouldn't rely much on my electrical connections and my waterproofing abilities, while probably they know better how to do certain things.

The little known suspensions brand and their proprietary motor and battery look like a disadvantage for the less support compared to more common components, especially if either gets discontinued.
 
And DIY conversions are just that DIY, wich means building the thing. And i'm pretty sure it's more profitable to do some overtime at work than to buy a used bike and covert it with expensive E components that don't actually fit easily.
Buying something like this with a year of warranty is a cheaper and more secure deal.

The suspension brand is used on more budget bikes. For example Mash uses it and Zero used to. However they are most known for MTB suspension wich is something completely different.
And after stopping a production of some unit they also stop building spare parts. For my Zero i have to find universal fork seals on AliExpress...

I did look if they have dealer near me (since i live quite close to Germany) so i could do a testride for my little Youtube channel. Sadly that corner of Germany is not covered by their dealer network. The one dealer in the Netherlands is a rental company that does E MX rentals on a simple track (like karting) on the other side of the country. They however only have the small ones on track.
So looks like i won't be testing one.
 
I was a tad negative about MX use, but where i can see this kind of bikes shine is in Hard Enduro. Lightweight, more than powerfull enough and battery capacity doesn't really matter. I know a lott of Germans go to places like Bilstain (a rocky gnarly Hard Enduro park).

I have emailed them about pricing and listing on their parts since there is nothing to find on their website.

Turns out the parts webshop is only in the German part and pricing for parts on the 85 an MX2 will be uploaded soon.
The pricing for the 85 battery is €1950 and for the MX2 battery €2350, incluiding warranty. Wich is not too bad i suppose.

The founder replied to have worked for KTM on their Freeride E and SX5E and later started to build own bikes.

The Fast Ace suspension is not for jumping, though.

I don't know those suspensions and I can't confirm nor deny what you have written, but surely the user wants to be reassured that the bike can be considered capable of withstanding violent landings before committing to some big jumps. I know that both Alta and Stark have done tests like the following; here I think there is even some ballast to simulate the weight of the rider:
Has HVR done anything like this? Maybe they have, but how can we know?
Well, they do write on their website, that the FastAce suspension "can handle anything", but they could have elaborated some explanation to back up this statement, considering the risks involved.

Another problem is that we don't know about issues that these bikes can have; often vehicles, especially new ones, have issues like problematic connectors, rust in certain spots and so on: if you buy an MX2, you just can't know.
And I'm sorry to say this because maybe it's a great bike and I surely look up to those people who have made it, but spending thousands of € or $ and then possibly ending up with a problematic bike with unknown resale value? And what if the company goes bankrupt and you can't find spare parts anymore?
Under this point of view a DIY conversion sounds better.

Something interesting is that they offer both left hand rear brake or traditional pedal brake.

Also, here is another not so expensive electric dirtbike with CNC milled triple clamps, while from some pictures it seems to me that the 2026 YZ450 has cast ones: I find it quite odd.

@ anybody who has knowledge about DIY conversions: is there a reason to have voltages like 72 or 96 volt? Like maybe compatibility with controllers? Maybe that's why HVR has chosen 78 V: it was hard to find other compatible parts.
 
That suspension will not break on impact, i'm quite sure of that. Springs will be proper too since that's not too hard to get right. It's the damping and the progression of it i would be concerned about.

To be fair, we didn't know about Stark either. The one thing that had going for it was a way bigger press release and more money behind it.
Parts is always an issue and i would indeed have seconds thoughts about that before spending on these bikes. But again, Stark had the same.

As for CNC vs Cast... CNC is comparetifly cheap on small scale while cast only gets cheaper with bigger numbers. So it's quite logical what we are seeing.

You are asking for quite some trust here. Can you please explain why you think that? Do you feel like commenting something about the frame and swingarm, too?

Press release tests and lot of videos in which people rode it hard successfully, back then, was way better than the unknown to me.
Here is an interview, released some months ago, in which Wass mentions tests like 50G landings: from 1:09:27:

I thik it's the right explanation. I know for working reasons that, at least here in Italy, it would cost some thousands € to make a pattern to be used for sand moulds, for example, for a component like a triple clamp. Then usuallly each cast triple clamp has a cost that depends on the batch size and then some machining is still needed.
So yes, what you say makes sense: they advertise CNC milled clamps to be something premium and it probably is indeed I suppose, and like you say, it's also cheaper for them.
 
I bought 2023 for my son when he was 4 years old a second hand HVR 50 from 2020. During the 3 years i had 3 topics:

1. 2023 I convert from foot brake to handbrake and the sealing of the new master cylinder was broken. After 2 mails i received two day later a new one. Very easy and good conversation.
2. 2024 A broken on/off switch. Realized on Friday before a riding weekend. After a urgent phone call and 2-3 WhatsApp chats I had all information to fix it... was a nice weekend.
3. 2025 The battery had a faulty cell. I send the diagnose data via the app to HVR (Yes... this works also there!) and they confirmed a broken cell. They repaired my battery for 110€! within two weeks.

I am still extrem happy with the great support (even during events at the weekend i got instant response for a charger question). Also for bikes far out of warranty they are doing a great job. I was so happy, that i bought already a new HVR 65Pro as next bike.

My message, HVR is company with 100% committed and passionated people. I can not make any statements for the new bikes because i have already two Starks :-) but for the company support i would give 6 out of 5 stars!

I really hope that Stark will repair batteries like this!

For the simple fact i've been riding for quite some time and have been bashing mopeds in 3-8 hours MX competitions, did abuse Chinese dirtbikes etc etc. Never have i seen suspension fail on impact (other than the brick cheap €500 pitbikes). I still have my moped wich was insanely abused for MX between my rides to school. That thing has 36mm forks (if i recal correctly) and a simple shock. If that lands on flat table tops from multiple meters this will be fine as well. I think the damping and such will be more of an issue compared to a KYB 48mm. But those limits are probably found well before the breaking point.
Add to that that FastAce is a budget brand, but at least a brand. I'm sure they did some testing since suspension snapping in 2 on impact is bad for business.
On the frames i know nothing more than from a video of them being welded in Germany by a German frame builder. Germans are, rightfully so, known to be great craftsmen with high levels of schooling and work ethos.
I wouldn't be worried about any of the frame quality etc, the E side is more of a mistery to me though (for lack of reseach perhaps).
I see less of a quality problem then a performance to price one compared to a young used Stark.

In the very beginning (of Stark) we had a video of guys riding it smoothly around a hardpack MX track and some claims, nothing more or less. The interviews and user tests came upon arrival of the bikes.
