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.

Only with the display Pro version you can choose assist levels.
Without display I don't see that possibility.

Is it certain that straight gears are used?
Or is this an assumption based on the image and torque value.
I ask, because they advertise with "low noise operation".

We will know it, when someone from us opens the motor and posts some photos

I just interpreted the photo on the Webshop.

With a torque sensor there is much less need to switch assist levels, as you can get the full range of power on every level. Of course it is nice to have the possibility to choose the amplifying factor of your human power.
Geeko has the buttons to switch the levels in the bottle cap.

...

Yes, but I won't be happy if the default assist level will be the highest.

On this battery holder, there are only 2 connectors visible on the bottom, so imho no option to switch levels

 

[stancecoke]

Yes, but I won't be happy

We could easily add a Bluetooth module to the display connector and use a smartphone app to switch the levels, show speed, power ....

The purple 6 pin plug on the battery bottom combines the light and the display wire, there is a 1 to 2 cable that splits to the "normal" green 5pin Higo display connector (used for UART in most cases) and the red 2 pin Higo for the headlight. The
connector on display side seems to be male, so it't not Bafang, but Kingmeter / Key-Display standard.
The display looks similar to the SW102, but is different. The "M" button is in the middle between the "up" and "down" button, not above of them. It could be the Bigstone M200.

Hi,

the description says it is the M200C so it is most likely this one
