While this product has been predicted for some time now, it makes perfect sense as far as SRAM is concerned and will be a boon to Brose. Shimano for years now has been both in the the e-bike motor game in addition to an endless legacy in the drivetrain space. Shimano has leveraged this...
OK, there seems be a lot of interest in internal gear transmission, motor gear unit, and belt-drive integration with Pole EMTBS. I've created a new discussion thread for this discussion so as not keep this Voima thread back on topic.
Cheers.

A number of people in this forum are expressing interest in some form of internal geared transmission system integrated with Pole EMTBs, whether it be new-fangled motor/gear units (MGU) or hub-based integration with a secondary...
What you guys are bringing up is arguably worse - unsprung rotational mass or inertial mass. Heavy tires and big wheels (29er) making the kinematics more sluggish because velocity changes are harder when mass is concentrated further away from the axle. This was at the root of the early 26 vs...
But you also dispense with the satellite dish-size rear cassette of a 1x1 along with the most likely a heavy T-Type AXS derailleur and the heavy chain, so it's not as bad as all that.
Agree with you on the "unsprung" aspect along with a more rearward weight distribution. On my light 26-pound...
The added weight (around 500 grams net) has always been a tradeoff with internal geared transmissions along with slight efficiency reduction (Rohloff practically minimal compared to derailleur , Pinion is higher), and cost (at least for the German stuff) has kept this tech from gaining traction...
Yes, I do mean to outfit the Sonni with an A12 and Gates. My sense is from the Rohloff side, it won't be too much of a problem. There's the T-bone brake mount brace to deal with and sprocket/chainring alignment, but these should be surmountable.
OTOH, the Gates belt drive part of the solution...
Yeah, so only 200mm and 170mm rear options (ie. no 190/190). The 190 in the list is for the fork.
If Bosch buys out Pinion (the're both German after all), then we may see some quick progress. Otherwise, Pinion is based on niche battery tech/controller and up till now pinion has been purely...
As much as I like the new Pinion gearbox motor, they are too niche to garner easy access service support (and dependency on obscure battery tech) , unlike Bosch which has a major international service and support footprint. Not until we see the likes of Bosch itself, SRAM, and Shimano get into...
Really loved my Voima while I had it, but I can say the only thing that never was right was the SRAM drivetrain. Had XX AXS (non t-type) and micro adjust never really helped, even after cassette swap and chain swap. Was either not dropping to tallest gear or was ghost shifting to upper gear...
1080KM before my Voima got stolen.
Sorry about your injury. I'm convinced that the Voima saved my ass on a steep technical section by a cliff about 2 months ago. Had I not been on that bike, I'm pretty sure I would have gone over the edge. Stable, planted and controllable are the...
Shots from a wonderful ride in Lake Tahoe.
Upper saddle area in High Meadows, nearing the the Mid-Summer snowline.
Hit the snowline where a rushing waterfall blocked the trail. Alas, the trail was about to ratchet-up in the technical department.
The bike was stolen the very next day, so...
And they made off with your 2nd Gen Specialized Turbo Levo Expert as well. You have homeowners insurance and are ready to file a claim.
So… What should I replace them with? Like-for-like or should I branch out? I was very fond of my Voima, but now the S-Onni beckons to replace the Voima...
For Voima, Fidlock is really the only option due to charge port location, at least for the K1. I also have a Topeak QR but it's not as easy to use in that location. I use QR on the underside of the Voima when I have the need for two bottles.
