GOBAO ECVT EMTB Mid-Drive Motor

The only ebike I tried with an e-cvt only worked if power was on. Without power you rotate the crank but that’s all. For a city bike this is an advantage, being some kind an anti-theft device
:)

What’s worth to mention is that both electric motors will provide torque to the chainring/pulley/rear wheel. If one motor would have only been used for changing the gear ratio, it would not be a very efficient system. In this respect, not much energy is wasted when varying transmission ratio. Even if the system is rather straightforward mechanically speaking, controlling it for proper feel/response is not something so simple. I would definitely try a eMTB with E-cvt to satisfy my curiosity.
The BMS will be programmed to cut motor power at 5% and only allow the CVT to work so you can get home.

Unfortunately I work numerous trade shows a year (CES, CEDIA, INFOCOMM, etc.) so I have a good perspective on the size, complexity, and cost of manufacturer trade show participation. I have to say, Gobao's Eurobike booth looks super impressive. They obviously are a sizable organization. This sparked my curiosity about the company.

People can dig into details about Gobao themselves but some points that stood out to me..
  • 1500 employees worldwide
  • Strong R&D with 6% of revenue invested; and 650+ patents
  • Highly automated “EV Level Automated Production” facility (>40,000 m²)
  • Automotive-grade quality and testing
  • European operations facility in Maisach, Germany
  • Private equity-backed, in IPO registration. Raised around $48.7M from investors

Their booth was the biggest at Eurobike and I think it was the most impressive too.

They told me they make a lot of electronic controllers for e-scooters. 60 million sold.

This Instagram story shows the difference in booth size compared to Avinox and Bosch. Shocking!

Do you expect them to have any big brands onboard when they bring the eCVT to market?
 
My guess is that next springtime we will see some comparative tests Gobao vs. Owuru e-mtbs and maybe vs. Avinox MG.
 
But didn't ZF also have a big presence 2 years ago then disappear?

Also I echo this feeling that my hype to get an M2s bike has been trampled by these mgu and 900Wh batteries

The problem with the ZF is that zero OEM’s wanted to take it. Good product but not different enough to Bosch etc, and that year Avinox launched with the M1. They went head to head with that, and we know how that ended.

These new MG eCVT’s are another step change. A new generation of motors. And a new wave of bikes will be designed around them.

From my position at the moment it seems that Gobao are further ahead in the development schedule and might get to market quicker.

Time will tell who ultimately has the better product. But I was seriously impressed with the Gobao.
 
I'm sure someone who understands batteries better than me knows why but my 1kwh powerbank charges at 1200w but the fastest current chargers are only 500w ish. Very welcome to see this 80% in 20mins!

so a few media people got to ride the GOBAO but the avinox equivalent was too early prototype to let anyone ride?

Be interesting to see if OEMS are willing to take the risk and be quicker to jump on this after missing out on sales delaying going to aviniox

I rode both Avinox MG and the Gobao motors on the same day. But not proper riding, car park multistories, up and down. That’s all. But gave a small insight at least.

Gobao’s super charger is 1500w and that gives the 900w battery 0-80% in approx 32mins
