Gobao appears to build a decent motor. The P120 is apparently an updated P100. https://velomotion.net/2025/08/gobao-p100-test-hepha/ Hopefully they addressed the rattle in the update to P120.

ZF battery at 756wh is 4.2 kg. Avinox at 800wh is 3.74kg 460g.

@Greg Watts Tell me more about climbing up the Grouse Grind.

@Greg Watts It's a rainy Sunday in North Vancouver, what trails make for a good February ride. Approximately 1200m climbing, beginning and ending at a coffee shop. Layout a full route.

These cranks imply to me they have excess capacity on their printers....lower sales of the A series than their production capacity.

It wouldn't make sense to go from 36v to 48v after just a single product generation. Especially one that's only really been on the market for 1 season. The product development team would have some a near term and long term product road map before they even started on developing gen 1 and setting...

Current Avinox batteries use an older 21700 LG 5000 mah cell. 20wh per cell. 600wh is 10s3p, 30cells at 20wh = 600wh. 36v. The packs are laid out in blocks of 6 cells stacked(2*3). With a custom battery using newer 6500mah cells in a 5 cell block Atherton's could do a ~720wh pack in a length...

Did you run the full 50A 60V 3000w for extended periods of time? That is a considerable amount more than the rest of the unit would have been designed for. Time to pull it all apart and see what failed.

If Avinox it's likely their own battery like Rotwild have done. 10s3p battery pack with a 6500mah 21700 cell will get them 700wh pack. This would fit in an roughly 60mm id round downtube. Length would be between the current 600wh and 800wh packs.

There is no actual way to "have the same number of cells" in a 36v and 48v system. All 36v system will have 10sXp battery. The 48v will be 13sXp. 10s3p = 30 cells 13s3p = 39 cells No matter how you scale it they will never have the same number of cells regardless of WH's.

Avinox is 36v not 48v.

The way the Avinox fanboys are fawning over rumours of changes it would make sense for DJI to have a shortened production cycle. Shorter lifespan than an iPhone and they seem eager to throw down to buy the new new. Gotta have that newest of new to show off at the trailhead.

People have been digging into Donut labs claims and it seems like it's supercapacitor hybrid rather than a solid state battery. https://x.com/LinusEkenstam/status/2008643160017453395

Is the Rocky Mountain Instinct SL the most overlooked bike in this conversation that kinda bridges the gap between SL and FF? They released a motor software update that gets 75nm and 700w. It's a 480wh battery and weight of around 20kg depending on parts spec.

I don't understand the not on a webpage comment? Something lost in translation there.
