Well that's just the beauty of Hybrid Drive ECT - there's really nothing premature abou it. How do you think hybrid vehicles (HEV) charge their batteries? The gas engine powers both wheels and charges battery. When you are idle at a stop sign, the gas engine stays on and charges the battery...

Man, is this dude gonna eat crow.

Niche has a booth at Eurobike. Not sure if they have a bike to demo. @Rob Rides EMTB or anyone else at the event, can you take look and report back if you were able to demo the motor on a prototype bike? With all the hoopla over ECVT now, pedal-by-wire is perhaps the only alternative...

Any on the forum attending Eurobike? If so, were you able to test the Gabao X1P. @Rob Rides EMTB, were you able to test the Niche motor?

Actually, in the particular use case Astro is talking about, you don't need a fixed wheel. There's no problem with human pedal power charging the battery with a free-wheel out back per inherent ECVT design. ECVT can transfer pedal power into either the drivetrain or the motor (acting as...

This is interesting, as it demonstrates Gabao is willing to integrated into other platforms. What I would really like to see is Gabao adapting their motor or even their ECVT motor into other legacy form factors. Namely Bosch Gen4 and Gen5. I could see a lot more take-up than for Shimano...

Yep. And also the critical announcement of the Avinox MG mtor. At long last, a vindication for ECVT technology and the true establishment of a deraileur-less EMTB future.

Both SRAM and Shimano have posted MGU patents last year, and these are of the gearbox variety not too dissimilar to Pinion. Let's see if these patents are just posturing or do they really intend to bring them to market. I really doubt it. And then there's Intradrive desperately trying to woo...

Not much use revising yesterday's OP as in the last day the ECVT battle between Avinox and Gabao came out of nowhere. Perhaps still fitting though is that my list of interests at Eurobike are still MGU focussed. More than anything I need know if anyone on the forum will be attending Eurobike...

So what's the alternative? Good old clunky Pinion gearbox? We've seen where's that led the market. Pedal-by-Wire might be the only other alternative I can think of.

Juice worth the squeeze angle is defensible on it own for battery regen. But when combined with ABS braking, it's insanely good when done right. If anyone ever gets a chance to demo a TM-B, you will know exactly what I mean. it really worked well on the Sea Otter MTB test trails. The modulation...

Then you've probably not heard that CVT was banned for Formula One racing because it created too much of a driving advantage.

See comments in [brackets] above. To answer the topical question though, yeah it will probably kill at least the full-power enduro side of the EMTB market in due time. It's not clear at this point if a super compact, light-weight, lower-power ECVT could be built for a trail EMTB. It requires...

Well if you can reclaim like 25% of battery capacity then a 600WH would have the same range as 800WH. That's a lot of poundage taken off your bike, not to mention improved handling with a small battery.

Agreed, but that's exactly how the TM-B works. Regen is part of their ABS braking system and it works wonderfully - I mean crazy good. The very best braking system I've ever experienced on an EMTB. The TM-B also has a belt guard as you alluded. That may seem like a lot of hoops to through to...

All the current announcements for the Avinox MG (and the Gobao XP1 motor as well), officially and through influencers, tout that their ECVT design can support battery regenation, which is actually the case due the inherent capabilities of ECVT Hybrid Drive design. However, I just realized with...

It would feel exactly like your are in a fixed gear; it's just that get to that gear 10 times faster.

Cute. Keep in mind there is no internal clutch to disengage the motor train from the pedal train (i.e. no float). The pedal axle is always connected to planetary system with ECVT. It would just be planetary gear backlash felt, so probably not a future glaring issue.

The degraded modes of the motor will depend on the design internals. The way ECVTs work is the gearing motor (not the drive motor) runs at a particular speed to set the ratio between the sun and ring gears or between the planetary and rings gears (depending on implementation). It's bit like...

Tensioners are the bane of MGU and gearbox designs. I've harped on this for quite some time and its problem that needs to be solved along with the motor tech. Villeger Dynamic a couple of years back (nothing from them since) has a ECVT motor design with integrated tensioner optimized for the...
