What's the answer?

Back in the early 80s I was running bear trap pedals on my BMX. Still got the scars on my shins!

Is that motor with torque sensor a available commercially ? I quite fancied trying to do a lightweight build. If not I guess I could use a Bafang 370 or akm85sx and use your bottom bracket torque sensor kit

The new Tongsheng hub kit arrived last week. I have been using it on my bike.
The kit comprises of a 1.8kg motor, a stem mounted LCD, a controller in standard aluminium casing and two cables: one goes to the LCD and the other to the motor.

stem mounted colour LCD:

Here it is mounted onto a 10kg full suspension bike with a 36V 10AH battery.

First impressions are excellent. Quietly powerful. I went up Pier Hill at 15mph with ease.

Neat ! Simplest (and lightest) conversion ever ! Is the controller in the battery bag ?

 

[Woosh]

Yes. It's the size of a 6 fet controller

 

[Peter.Bridge]

What rpm is 26" wheel model ?

 

[Woosh]

It behaves as expected, so expect 250rpm. I am still getting to know the new kit. There is no manual yet.

So a full suspension torque sensored e-bike with 360Wh battery for 14kg ! Bet you can't buy that anywhere !
