Help with Emojo Caddy Pro trike power (Reposted to Trikes/other)

Reposting here from Garage

Hello,
About two years ago I was diagnosed with ALS. Through the pandemic our Benno Boost and RadPower City step through got us out and about. We put 1000 miles on each. I’ve recently needed to move to a trike. The Emojo Caddy Pro. I’ll repost the following in another thread, but here is my issue.
When I engage the pedal assist, the bike really takes off leaving me spinning my pedals faster than I’d like. Is there a way to reduce the power level so the assist is more subtle?

any feedback is greatly appreciated.

The short answer is no.
(assuming that you have tried all power levels)

The bike you're referring to, Emojo Caddy Pro has cadence sensor, not torque sensor.
It's just a nature of cadence sensored ebike. It has this switch "on and off" feeling.

It will give you more assist than you need, but sometimes it won't.

Personally, I like cadence sensored ebike because I like getting pushed around, I enjoy zippy ebikes.
However, many people, including members here on EBR complained that cadence sensor scare them because it can be unpredictable.
As you described, depending on the situation, it will give you more assist than you want, because cadence sensor will detect if you are pedaling or not, that's it.
It doesn't detect how hard you are pedaling.

For the difference between torque sensor and cadence sensor, this video will explain to you better than I can.

Yeah I watched a few comparison videos yesterday and understand more now. Thanks.

If you are, or if you know someone who is handy, you can get torque sensor.
This would require torque sensor (usually bottom bracket type, different than one in the video above) and possibly display and motor controller (if they are not torque sensor compatible)

Just letting you know that it is possible to get a torque sensor.

In addition, although I have heard that hub driven torque sensors do work very well, it is not quite as Yamaha or Bosch mid drive torque sensor.
I personally have ridden some torque sensored hub driven ebikes, like Stromer and BionX powered ebikes, and I felt pretty good.

The Benno bike has a mid engine with torque sensor. Much less lurching ahead. The Rad Power is a cadence sensor but rear hub and is very smooth in its acceleration.

Interesting that a torque sensor is an add on. Don't Bafang motors come with a throttle as a stock item? Can you use rhe throttle to get rolling smoothly, then start pedaling?
I have never ridden a bafang powered bike, so no experience with them, but throttles on motorcycles can be gentle enough.

Ok. I think I understand. Sounds like an add on torque sensor might help if you can get a bike shop to install It.
