Legendary enduro rider Graham Jarvis is putting his name to a project of electric Enduro bike.

Lighter than a Varg, hot swappable batteries (although obviously smaller), app controlled from your own phone is what a lot of Enduro riders have been asking for, so it could be interesting.

The bike is light but so are the details about this project, with a production start scheduled in about 4 months...

50 kW (68 hp)
95 kg
5.6 kWh

That makes it an intriguing prospect if it's specced more like a Varg than a Surron to handle rough terrain, and if the price is right (no information about that).

Sirris suspensions, like the Dust, e clutch, and likely made in Austria

JARV-E | Electric Hard-Enduro

Revolutionary electric hard-enduro bike co-developed with legend Graham Jarvis. Up to 5 hours of riding time on a full charge, 20-second battery swap, 45° climb capability. Fully built in Austria.

Founder has been developing e-bikes for a while and finished Romaniacs emoto expert category last year on supposedly one of his prototypes

Some additional information from the website, some of which is got hovering the mouse cursor on the + signs on the picture:
• Sirris F43 suspension; interestingly, it seems to be a dual chamber fork with Ø43 mm stenchions but the F43 writing pops up hovering the cursor over the rear shock
• rear shock without linkages and a visible tilt that I presume achieves progression instead
• 21"-18" wheels
• e-clutch
• CNC milled swingarm and triple clamps; in other topics we got to the conclusion that those propotypes have machined triple clamps probably because casting would be more expensive for small batches, but apparently this is marketed as a permanent feature
• 3.4 kW charging
• Jarvis is not only going to sign the bikes, he is part of their team: "He leads riding development, testing, race strategy and the long-term vision for JARV-E." He has also developed a riding mode available for the customers.
• The battery capacity after 500 charging cycles is expected to be 80%.
• two years warranty

I like that the prototype is being raced in important competitions before they even produce the bikes. Racing is the real test people want to see.

They are also hiring to expand the company.
 
Good eye!

I like that they already foresee to make replacement packs available.

The path from prototype to production is hard, they appear to be at very early stage without any release date nor price.
 
So, not a motocrosser with that frame design, I do like some of their setup choices though: Chain primary rather than enclosed gears, simpler, lighter though slightly more power loss. Main shaft is also the swingarm pivot so constant chain slack at all times. IIRC this impacts anti-squat though, not sure it's really a concern at hard enduro pace vs say, road racing where I normally play? Front sprocket changes are going to require major disassembly. Looking at long term strength, that steering stem area is spindly, and the swingarm pivot is behind the main rear downtube with not much visible bracing / triangulation? Again, not a MX/SX targeted machine.

EDIT: Looking closer at the swingarm pivot area, I just realized, the pivot point is adjustable. The silver side plates that also hold the pegs are the entire pivot point structure, it's not supported by the frame at all. The forward mount point for those plates has two holes, by changing which one you use you can move the swingarm pivot point up or down. This alters the shock progressiveness and swingarm angle. It also moves the pegs relative to the seat/frame a bit too so, interesting... The mount bolts for those plates are blocked by the primary sprocket so can't go all the way across for strength on the rear bolt, front bolt looks to possibly be able to be a single bolt across the frame with a gusset tube between for strength?

SIRRIS suspension scores again, the rear geometry worries me though... I'm used to PDS / linkless setups, this is setup to be VERY progressive, and eyeball math has me worried that a hard hit could push it 'over center' depending on how hard the stop is on that shock? I'd like to get the actual numbers on it to run the math.

That said, I do like finally seeing a full size machine that appears to actually benefit from going on an electric diet. This has my attention as likely a closer match to my actual ability set these days, and much lighter, this is closer to my two strokes that I love weight wise. I do hope they come out with alternate rear side plates with more number plate area AND mud flap function.

I haven't found pictures of the bike from the right side, but yes, from the left it looks like that. Some BMW designed Husqvarnas like the TE 449 used this solution, that they called CTS: Coaxial Traction System. Here is an interview about it to an Italian professor from back then; the subtitles seem right except for when he mentions landign from a jump doing cross country: it's motocross, not XC:
The advantage of less slack in the chain + the instantaneous torque of the electric powertrain must make that one of the most reactive motorcycles ever made.

Well, I've found out that for that fork, for example, there are spare parts available like this rebuild kit and tutorials like this about how to change the spring. I don't expect to find as much spare parts and information as with older, more common manufacturers, but I also guess that they would be cooperative if asked technical questions.

When you say "over center", do you mean like this? It doesn't look like it can compress so much.

That's exactly what I meant, either going digressive or absolute worst case scenario, the shock starts forcing the swingarm UP. Ran into that with some Chinese pitbikes back in the day, they relied on a rubber soft stop to keep things in check. Hammer a jump as an adult on said bike and suddenly your swingarm was stuck beyond fully compressed. (And if you had adjusted the chain as per the stickers, likely either snapped the chain or bent the output shaft...) I have to assume they're aware of and designed to not allow that to happen, but it was my first thought looking at the layout.
 
Is Jarvis allowed to do this with his Husqvarna contract? Or has that ended?

Also that's a very tiny battery for it's capacity. Wishfull thinking or some fast advancing tech?

This has business of being on a MX track for sure. But i can see this being a weapon in places like Erzberg, Pascuet, Bilstain etc. This will crawl extreme stuff like nothing else.
 
I signed up, but have not made a deposit.
I asked via email for the wheelbase and seat height, which I could find anywhere.

  3. Your individual delivery timeframewill be scheduled based on your assigned bike number.
 
Great infos, thanks!

EX is under 11k€ before tax so JARV-E would be around 1500 € more expensive.

First deliveries expected in March, that's... really close! Maybe they have stashed a factory somewhere in the Austrian Alps or maybe they'll go with a more modest approach and low production output. Or they're overly optimistic, which would not be a first for an EV company 😆

I hope they can deliver during the first half of the year, they have an interesting approach and it's always good to have more choice.
 
Those bikes are not available for test rides and only the founder has tested one, as far as we know. Therefore, IMO they should provide potential caustomers with all possible information: wheelbase, seat height, dyno chart, weight distribution, brake rotors diameters and so on. Personally, I wouldn't spend that kind of money on a bike I know so little about.
 
They should provide potential customers with a lot for the huge a deposit. I think I would take a chance on the 100.00 on the Verge to 3800.00 on the Jarvis... I would be very careful laying out that kind of money for a promise of production. We all know how that can go.

💯 agree. $100.00 US ok maybe worth the risk. Almost $4k US you better show me pictures of my bike on the production line and when it is loaded on the skid and at the dock ready for ship. We all saw what has happened in the past. Promises made promises not kept.
 
Once the product arrives at U.S. Customs, I believe the customer is responsible for paying an additional 15% (or more) import fee (Customs duty plus broker fee). The sellers will not usually tell their customers this information and we don't find that out until we're already on the hook for the full amount.
