on a 'KSL chassis-like', with 500-600 Wh ultraslim battery ... wabagadoowah ! :love:

Even better : now that we have VPP (crestline) with bosch motor, what if could buy a DIY frame, buy the complete ZF kit and ...

Probably the most energy dense ebike motor ever, people still complain.

The batteries they are proposing with the system are the same energy density as ones in 2 year old bikes, which definitely defeats the point of the 200-300g saving on the motor.

Hopefully they will be compatible with third party battery packs

Missed opportunity ?? For who ?
Who told you that bike brands are rushing to get rid of current drivetrains ?
In the end, I'm sure ZF have talked to all major bike brands before developing this system and i'm gussing they didnt hear that it's a must.
I'm sure when the market will demand it,they will have a first class solution.

Are you offended by what I said or what? Did I hurt somebody's feelings? Do I need to have exactly the same opinion as others? I say they missed the boat on this. Take it or leave it for all I care.

I agree that it's somewhat disappointing (to me). If you were hoping for a 2.5kg motor (plus whatever the clamp weighs) with a great power to weight, then yes you wouldn't be disappointed. But I'm not.
I'm hoping to see the lightest possible system and ideally the lightest possible system with a central gearbox.
With FF EMTB's we had a death spiral of heavy motors with heavy batteries, necessitating heavy drivetrains, wheels, tyres, brakes, and suspension etc, so a heavier bike necessitating a bigger motor and battery to power it all, necessitating heavier tyres, brakes etc etc.

The SL format cut the power (and energy) to the bare minimum, and so allowed the use of all the existing lightweight non-e-specific parts. Since then, manufacturers have managed to keep this formula but squeeze more power out and a little more energy in (which is great).

Now with the emergence of MGU's we need the same format. Limit the power and energy to a modest level, then the gearbox can be built as lightweight as possible and result in the first SL MGU bike. THIS is what I am looking forward to.

Pretty sure it can use other batteries :)

Looks like it's pretty wide but no word I have seen on the Q factor? Not a deal breaker for most but can be for others.

Not seen a post on the new ZF motor yet.

Here's the article. Looks impressive!

Interesting….. as long as the Achilles of all e-bike motors is adequately addressed…… sealing…… a large nr of e-bike users ride outside of the Goldilocks zone that manufactures test and design their products in….. ZF should be applauded for making a high power motor in a concentric for, but a slightly larger motor with serviceable seals a maybe grease ports or a moisture sensor to indicate contamination and urgent service is required would be more beneficial…..

Let's be fair gear box motors are still in there infancy
As people say they make fantastic auto transmission that I for one have three vehicles with them in
But I for one would like to try the system especially with this clutch system to save the working against the rock strikes and virtually instant pedalling

I agree. I think all motor manufacturers should install a moisture detector at the bottom of the circuit board and sell seal kits to anyone ( just like Rockshox and Fox do) so we can maintain our expensive purchase.

Agree, sounds clever. A clutch could also be beneficial down the line if/when they add a gearbox to the motor. Or even a dual clutch design like in cars.

It's oil filled and g'teed for life - might get the other manufacturers thinking!

A promising development, however the devil is in the detail! It may have a massive list of exclusions and a life definition of a few hundred hours…… if ZF’s warrantee is genuinely comprehensive then this is truly a big step forward and will shake up the market.

I think they said 30,000kms

I would like to see a promise to publish a service manual & sell all major motor parts including circuit board for design life + x years - something the major players refuse to do. Then we will know that years in the future it will be possible to fix an out of warranty motor instead of junking it.

The devil IS in the detail especially:
  • submerging in water or another liquid

This will never happen, ever. If anyone thinks that ZF will be this fluffy friendly teddy bear and be your best buddy with all the parts, info, manuals, what not, get off the stuff you have been smoking.

ZF will not be special in this approach. All manufacturers move towards this idea. Right to repair is a massive battle in the US. Despite all this green, eco, save the planet, be vegan, stop the oil moron BS, one more junked motor will create the need for another purchase. And it all will be because one crucial 10 pence washer cannot be changed without 250GBP service charge and additional 200GBP of other costs, or simply because they do not make these washers anymore.

These warranty ZF terms are as vague as f**k, almost all of the terms lack a clear definition.
