First DIY conversion kit with cassette integrated torquesensor

[stancecoke]

Yose Power has a new offer for a complete conversion kit. I was looking forward to find something like that, since I've startet experimenting with this sensor in 2022. I had to write my own firmware to make my Lishui controller communicate with the sensor .
There is just one cable from the battery to the motor, no wires for a display or PAS are needed.
For people who want a display and lights, there is a A3Pro set also.
The controller could be a Bafang? The display connector seems to be the same as in the Bafang CAN system.

Unfortunately, Yose seems to use a motor with a straight-toothed gearbox, which would be too loud for me.

hmm.. is the controller in the battery then?
( this would be a way better place than inside the motor )

My kid's ebike has a kit kind of like this, and yeah, the controller is hiding in that fat bottom of the "drink holder".

A quick image search on "water bottle battery controller" finds a few including this one EBS, IPS non-sensor controller 36V 15A in water bottle cage - fast commutating

which is also available from ohter places, but I figured I'd just link the one that can probbably be trusted.

The "Geeko" system is available for quite a long time already, but it has no torquesensor.

Battery holder integrated controllers are available for many battery forms, but for the KClamber sensor, you need a controller, that has a second UART. That's nothing special in principle, many cheap scooter controllers have one UART for the Dashboard communication and a second for the BMS communication, but there was no plug and play solution for an Ebike system before, that uses the cassette integrated torque sensor in combination with a battery integrated controller, to get a lean, stealthy, easy to install conversion kit.
Grintech offers the cassette integrated sensor for its all axle motor also, but not this smart combination with the bottle battery.
