Bosch Mid drive
integrated into swingarm to balance weight
a VPP'ish pivot
belt drive
400wh pack
Magura MT7 hydro brakes
Rohloff Speedhub
Rockshox Pike fork

Pretty dope.

Looks kinda like they hacked up a subpar frame and welded on a nice looking bottom bracket.
It just looks hacked together instead of being designed from the ground up to me.

Car companies don't seem capable of making a bike look remotely as nice as their cars.

The bottom of the bike is artful, but the top looks like something from walmart.

Key stats:

8.345,00 €
45km/h max speed
25kg
400wh
130km range, LOL

I wonder if the motor power cuts out when you switch gears.

 

[neptronix]

130km/80 mile range with a max speed of 45kmh/27mph on 400whrs?
This assumes that the electric motor is pushing maybe 20-25 watts and the rest is pedaling.

Cool, i'll pay 8 grand for that.

Grace MX came into my mind:

I think it looks over engineered, and most likely will not be as stiff as it should be (low profile rear end). I'm quite surprised that Nicolai Kalle is working with them.

The Bosch drive unit has a torque sensor, shifting is no problem with this system.

You need 500W at the wheel to go 45kph, this is 600W Battery power (assuming 83% total drive system efficiency), so what you need is 600Wh/45km ~= 13Wh/km battery energy or 500Wh/45kph~= 11Wh muscle energy (assuming 100% eff)

you get 400Wh*0.83 = 333Wh to the wheel
for 130km you need 1430 Wh at the wheel. 333 Wh come from the battery (23%) , 1097 Wh from your legs (77%)

So there is 115W from the motor and 385W from your legs, which you do for 130km/45kph = 2h 53min, sound like you are neil armstrong, dude!!

IMO it should be the other way around, 115W from the legs are fine. So the battery must be 1097Wh /0.83 = 1.5 kWh to faithfully meet that claim

130km/80 mile range with a max speed of 45kmh/27mph on 400whrs?

[izeman]

all those range estimates given for ALL bike i saw are a big lie. i don't know why this is allowed. it's like: this car does 100mpg or 1l/100km. for sure. if you let the engine idle in neutral and go downhill all the time. lol

Those numbers are out of this world! :wink:

 

[Lurkin]

Expensive toy.

I would love to see the suspension pivot after a couple of decent drops.

Seems a bit unfortunate.. really missed an opportunity to move the rear suspension to the rear triangle to double (potential) battery capacity.. not a fan of the battery by default being out of the inner triangle.

And the price tag... would rather a Haibike I think.

 

[amberwolf]

"Heisenberg", eh? I dunno...I'm uncertain about all of it's specs....

 

[Warren]

To be fair, they list 45 kph as the maximum speed, and maximum 130 km range. Electric car makers, including BMW, also talk about their maximum speed and their maximum range. Obviously, they don't mean at the same time. But people want to believe the best, so many have been disappointed when their electric car doesn't go as far as the EPA claims.

The car companies, and the bike makers, are setting themselves up for failure, with those best case numbers.

Neil Armstrong? You mean you must be able to peddle to the moon? :lol: Just joking bud, kinda funny... It is Lance Armstrong

But for real 600W = 45km/h? Sounds a bit fast to me?

 

[Dunkenb]

Is that frame design basically a unified rear triangle system, found on the cheapest mtb's? If you ever have to pedal it its bob up and down something awful?

 

[nioko]

Most likely not, the description says that it's neutral to the power delivered, and will always work, regardless of the load.

Nicolai Bikes were always very special, sp I expect this to be good, even if I don't like the looks.

 

[2old]

Hey, wasn't Heisenberg the father of the uncertainty principle (as well as IIRC, Walter White's alias)? What can we expect from a company named after him? Seriously, though the urban model for about $4K US seems enticing. Probably won't make it to the US for years though.

 

[Voltron]

Re the unified rear triangle, yes... the dual parallelogram rear suspension IS a type of URT (unified rear triangle), but not swinging from a single pivot. Its a whole different beast though.Careful design of the linkage neutralizes the chain pull effect, and allows the rear axle to not just swing a semi circular path around the pivot, but lets the wheel move upwards and backwards at the same time. Here there is no chain (or rather belt) pull as the BB is part of the rear unit...but all the other designs I've heard of like that were unpopular for the way it felt like the pedals were jerking around under your feet as the suspension moved... maybe they got that worked out.

 

[dh-paule]

The rear suspension works fine, really fine. No matter if you are pedaling, sitting, standing... it works fine. You can not compare with the old unified swing like a Trek Y33 (had one, years ago) - forget about that.

while my previous 6500W / 55kg stealth bomber is an e-motorbike, the heisenberg xf1 is much more mountainbike than e-bike... but it is nearly the same fun At the moment I am in love with the xf1

 

[Voltron]

That looks really nice...

I see HNF Heisenberg has now gone with a cargo trike flavour:

(Translated via Giggle from original German

New cargo ebike of hnf heisenberg
We're proud of you at this year's eurobike our new elaste bike cd1 cargo to introduce. The Cd1 Cargo Ebike can you in Hall 2 Booth 204 visit and on the demo area booth 222 like to test drive.
The new and powerful cd1 offers revolutionary design and driving performance with tilting train. It combines the payload smöglichkeiten of a small car with the agility and flexibility of a bicycle. The quality workmanship is on the highest level and as usual, only the highest quality components are
Blocked. His Powerful Bosch-drive is completely in the complicated aluminium frame integrated. Of course we offer the ebikes cd1 or how all the hnf-Heisenberg design line, also known as s-pedelec
With 45 km / h. In this geschwindigkeitsklasse offers the bike a revolutionary driving experience, which is the category loads wheel redefined. The Cd1 collects the claim once again and to set standards

[Hillhater]

I guess there is a market for these high end bikes...in the same way there is a market for Pagani cars.
Sorry , But really overengineered, over detailed, and over priced , for a mud plugger !

Hehe... HH? Was just explaining to another here, that it was the "wealthy" that started a trend riding w/electric assist:

German eBike manufacturer HNF Heisenberg announced that it will be using technology developed for the BMW i series to build its newest electric bicycle.

The Heisenberg XF1 mountain bike features a drive unit swing arm that was originally patented by BMW Research and Technology. The swing arm was developed during the early concept phase of the carmaker’s i-series, which includes the all-electric i3 and the i8 hybrid sports car.
