To be precise, the motor stops its support at very close to 28mph (45km/h) as that's the top speed for pedal-assisted ebikes in Europe. The motor could run at higher speeds.
To extend on the whole cloud/remote abilities: We included a GSM chip on the bike's central brain which can communicate with a central server, which in turn allows remote management - whatever that will be in the future. For now, that means retailers have access to remote error analysis on the bike and customers can see their bike's state of charge, position, average speeds, ... Additionally, a customer can lock and unlock his bike and enable (and disable) a special theft-mode (which blocks the motor and starts GPS tracking) with his smartphone app. The bike firmware can be updated over the air.
This all means that there is quite a lot of background infrastructure running for this to work and it took definitely above 2 years to implement. With all this in mind, we hope customers are willing to pay the admittedly very high price. Also: This is more a "show off". We wanted to be the first to introduce these features into the ebike market but do not expect this bike to sell like crazy (we would love to see that happen, though).
The price in Switzerland is 6690CHF and in Germany 5690€.
