15lb of just batteries lol, no thanks
Correct, the discharge rating on the existing cells is too low when used in smaller capacity packs.
The newer 6000mah molicell 21700's have a higher discharge rating, and would be appropriate for standalone small pack usage.
That is generally the case with the range extenders that are on the market. That's why many of them are built with an output voltage that is higher than the main battery (with more cells in series) and then trickle charge the main battery using a step down transformer within the bms. If you're trying to build it so that the bike draws from the range extender first, or so that you can run off the range extender solely and without an in frame battery, things get pretty complicated.
Does anyone have a clue as to why all these longer travel e-bikes are coming out with 76° seat angles? I thought we had moved past this
You can't think of a reason?
I hate slack seat angles too.
Due to the motor. Also, most people drop their seats to some degree on steep technical climbing on e-bikes. A steep seatube angle isn’t as important when you have a motor.
Longer rear ends is part of the puzzle.

I just bought a Crafty (Bosch) knowing full well the Zendit (Avinox) was being released. The Crafty geo better fits me and my terrain. The Bosch CX has more power than I need already. The Zendit is also like another $1.2k. The slimmer downtube and 3 lbs of weight savings would be nice but not worth it consider the Crafty is a better fit.
When will we have sub 22kg big battery full power enduro emtbs? I guess it relies on the battery savings mostly. Almost nothing gets close even to the 23kg mark either, except for the teewing flux and mondraker zendit. Saw the new forbidden, it reaches 24 kg with pedals and 800 battery.
My L Wild weighs 22 kgs/ 48.6#s (verified on 2 scales) with all the things ready to ride, dual coil suspension, dual DH wheels, dual DH tires, 220/ 200mm e-bike rotors, electronic shifting and 200mm AXS dropper. That said, I curated the build very carefully to my needs but really the only WW thing I have is an 11 speed cassette.
It's doable. I only have a 600wh battery however, which was my preference.
If I had chosen trail tires, a stock Mezzer, the stock Float X, high end trail wheels or even Berds, & a OneUp dropper it would weigh about 20.5 kgs/ 45#s quite easily. If that's your thing; but then it wouldn't really be a 170mm AM e-bike. I call that the Amflow build, and it's being a bit tricky if you ask me. But I'd consider a light build on an SL e-bike for sure to make the lower power and battery go longer and it to feel more like a bike.
Because they are reusing the frame for wildly different travel brackets
My thinking- most of the time I would want a sub 50 pound ebike for just normal riding. Probably never get into turbo, or even beyond the "standard" 700ish watts of assistance.
Sometimes, however, I might want to go exploring and feel like I'm more on a surron, crank it up to 1500w, and have the range to really get out there. Any handling concerns would be secondary.
Like having a normal ebike and a Bonnell in just one bike.
I agree on the seat tube angle deal. I really like a shorter top tube for a more upright riding position when seated.
Not on the e-dreadnought, it is a dedicated frame.
Long chainstays, short reach, tall stack, and a motor make a steeper seat tube angle actually undesirable.
Bosch are bringing out a fast charger, 12 amp. Will drop with the 120nm update next month but the charger will not be out until Q1 2027
Do you know anything about possible updated batteries with higher density?
More curious than anything as unless it was a substantial upgrade in density of > 25% I wouldn't bother. And that assumes it's even backwards compatible.
I think quite a few of the OEM's with lots of bosch inventory will be pressing hard for a much earlier release.
Because the weight and location of the battery adds more weight to the front and the long/rearward chain-stays also drive weight forward. Don’t need to put the rider over the front wheel as much.
Are we calling 76 degrees "slack" still? I must be out of touch....If you look at how things have to be packaged in a lot of modern bikes (motor, battery, shock, bottle cage etc) you will see there is a practical limit to how steep it can be. Also most brands only post the "effective" seat angle, but the actual angle of the tube can be much slacker, so if you compared them at your actual seat height the true position will be quite different
I was replying in jest. I’m a tall guy at 6’2” so I really can’t stand slack seat angles on extra large bikes.
Effective SA measurements on larger bikes are always random. If it’s too slack when you raise your seat, your body positioning gets put into a pretzel. One of my favorite bikes I used to own was terrible to climb, because the taller the seat the more my legs were put into a recumbent position. I also had to lean really far forward like I was on a road bike…
I’ve learned It’s not quite as important on E bikes, but it’s still my preference.
Any idea when the 120nm update will be dropping?
And will it be 120nm for 30s or continuous?
