I currently have a Tribrid bike (Gas, Electric, Pedal) the front wheel is direct drive rear is geared. Both are the same voltage and watts. They are set up so I can turn on or off any combination with or without the engine or pedals depending on the need for range, speed, power, all wheel drive. I liked the idea of adding a mid drive as well just for the overboard mentality but I can't think of any practical reason to do it besides the option to use the bikes gears. Perhaps you can give details on your experience and how you end up using the motors in real every day travel.

The pedal assistance via torque sensor is another level compared to the PAS sensor, I have much more control in my pedaling, the phantom pedaling is no longer there so I can accompany my son without always keeping my finger on the brake, However, the project was born because I wanted to keep the hub motor only to use them with the accelerator

Good to know. That pedaling without resistance is a pain. It would be worth it to add the mid drive for me if using the gears with it gives more options and a top speed comparable to the gas engine but knowing it also has a torque sensor to match the pedals is another plus.

Hill climbing and hauling heavy loads is where the mid drive motors really shine.
The bike I’m currently working on is going to be setup similar to this one. Like the Tribrid bikes the multi motor option has a lot going for it.
2x2 is very handy for loose or steep surfaces. I was running just the front hub motor through some sand a couple of weeks ago and it became quickly evident that I was going too fast. The rear wheel started to fishtail like a trailer. I had to slow down and kick the gas motor on. Then I could comfortably speed back up with both wheels providing traction & drive.
The mid-drive motor is fantastic for the steep hills and towing heavy loads. (like other bikes with their riders) but I don’t want to use the mid drive motor all the time because of the excessive wear to the drivetrain.
The two hub motors can be used dynamically one at a time for economic long range travel or together for fast travel on flat ground that doesn’t put wear on the drivetrain.
Just like the Tribrids it makes for a very versatile (if somewhat heavy) bicycle. Basically, if it still rolls, it’ll get you home.
It’ll also have all the capabilities of the super bikes while retaining a completely road legal status.
Being road legal with a hyper-capable bike (like the Tribrids) is a big advantage. I’m scheming a way to add a small gas engine to my next build. I’m not quite there though. (yet)

Oh yeah having all the options is exactly why I built my bike with gas and front and rear electric hubs that way I can keep going no matter what breaks and switch between running with the cars on gas or high speed all wheel drive with both hubs switch between direct drive hub or heard for range/legal speeds or turn it all off to legally use bike trails. As long as one of those works I just have to keep my tires rolling so I carry a battery air pump manual pump spare tubes and patches as we as enough tools to tear the whole thing down and put it back together on the side of the road. I was considering using a sturmey archer 3 speed hub as a jack shaft transmission for the gas engine but was also curious if maybe I could run a mid drive through it instead of a derailer transmission. The sturmey archer 3 speed hub can take the torque but the heat build up from the speed is the problem. Well let's all have fun building our monsters.

Besides the novelty, what's the point? - besides consuming a battery in a few minutes...

The PAS pedal assist really sucks at 25km/h legal in my country, I have 2 hub motors that only work with the accelerator. I changed my ignition keys to enable throttle. So without the key inserted I only go at 25km/h with the bafang central engine while with the key inserted I go up to 60km/h with the motor in the hub and I can use the accelerator

Thanks for the info, nearest officers will look into this, thank for cooperation!
TourSure8564@reddit (OP)
When I got the bike I approached some local agents to ask for information and they told me that the important thing was not to use the 2 engines, not to enable the accelerator and not to exceed a speed of 25km/h on public land, elsewhere they were my problems

Thasss isss maaaa biiigggg SUV maaattt, yoooou heaaarr me?

I have a dual motor and just love it.
The rear PAS is silky smooth and I
control the front using throttle only.
The two motors offer a lot of flexability
as the front is a direct drive w/regen
and the rear is a geared hub.
The thought of adding a mid-drive
never really crossed my mind but a
torque sensor would be nice.
Thanks for the idea!

omg having multiple ebikes is lowkey addicting.. i started with one and now i keep dreaming about getting a second one for different terrain lol.

However I have 4 e-bikes, 2 electric mini quads and 1 minibike with xiomi m360pro engine

Mine was already an awd e-bike with 2 motors but I didn't like the feeling of the PAS system and I prefer assisted pedaling via the torque system, I added a bafang 750w motor so now I have 3 motors😅

Fair play, I'll bet it's fun! 🚲⚡👍
