That really needs to change with some yet-to-be determined industry agreement that allows more flexibility and upgradeability.

Resistance with the system turned off As an owner of a bike with a Bosch Performance CX motor, I never use Turbo mode and use EMTB mode instead as I prefer a natural-feeling system with progressive assistance.

[@dansadventures5514]

​@@Yunam.sisandbro the difference in motor weight is pretty much meaningless compared to the overall weight of the bike and rider. Even the choice of tires can make a larger impact on the weight. Most reviewers are raving about the motors with built-in gearbox even though those are heavier. While I like lighter full-power bikes, I don't particularly care where the weight savings come from. I also like less chunky, sleeker-looking EMTBs and a smaller motor helps with that but I don't care about the weight of the motor.

[@svenweihusen57]

@@dansadventures5514 One of the problems is the weight of the battery. The question is what you want: full power all the time or support. With a 900 Wh battery you can't build a light bike. eGravel bikes can go as low as 13kg with less punch and 200Wh. But that's enough for fit bikers when you want support when/if you need it and not all the time.

[@dansadventures5514]

Yeah, the battery is a big part of it. I've done 60km and 5,000 feet of climbing on backcountry mountain trails with a 625 Wh battery (mostly on EMTB mode) so 900 Wh is overkill. I would choose a lighter full-power bike with 500 Wh and an extender for the epic days if a brand provided that option.

Well not exactly their first as they did have the Sachs/BMz in their micro mobility section when it first was introduced ., it has since been sold to BMZ which supplies the batteries for Brose and the former Sachs . i m wondering where ZF gets their batteries from and where exactly is their new motor built/assembled .

Their batteries are kind of heavy and outdated though, the 756wh one has a weight of 4,2kg. The one of dji has 800Wh and weighs 3,7kg

@oldkayakdude Yeah, but solid state batteries development will first come into the car industry and maybe after that we can hope, still a long run. Maybe 2030+

Chinese Dengfu makes 840Wh and exactly 4kg!
