Rad Expand5
My OEM Tektro Aries calipers are less than stellar. I've had them unexpectedly go out of adjustment often -  and a couple of occasions they both went out at the same time. (I had to "Flintstone" it to stop on city streets.)
The cable isn't slipping, and all ferrules are in the correct spot.
I've given up on them, I'm hoping for a recommendation for an upgraded mechanical for the front and rear.

So I risked it on my own since no advice here

The Drift Maniacs 34/11 seven speed freewheel was a direct replacement without requiring re-indexing or a long cage derailleur, I can now contribute by peddling - even at full speed where the motor back-emf starts to inhibit.

I changed my freewheel on my Aventon Abound to a 7 speed with an 11 tooth on the small ring rather than the 14 tooth to reduce clown peddling when traveling with the throttle. Would a RadExpand 5 accommodate similar?

I just bought eight pairs of two different sizes of rubber bar spacers from Amazon. They work for my phone holder when the original ones would't

Are you able to confirm that?
My Abound's battery connection block is hard wired to its little controller. The fact that there are 5 wires from the block makes it impossible to add and parallel a second battery

I'd like to know if there's a possibility of adding/paralleling a second battery

So I thought I'd follow up since the RW5 has been available for a bit now.
Can the speed restriction be increased to 40 km/hr like the RW4 could?

Also, I thought I'd ask if the battery is hard-wired to the controller or is there a connector between the two?

The RW5 has a torque sensing bottom bracket, the Area13 controllers don't support a torque sensor.

Regardless, Are you saying the RW5 can't be set for a 40 km/hr top speed?

I'm interested in the new Radwagon 5 with torque sensor. I'd like to know if it'd be worth it to sell my Aventon Abound and buy a RW5. I really like my Abound's Torque Sensor bottom bracket and it's nice to see RAD followed suit.

Does the battery wire to the controller via two conductors or is there some sort of handshake process going on between the batt and controller with more than two conductors? I'm asking this because I'd be interested in adding a second battery through a DatX2 combiner for better range.

Can you derestrict the Canadian speed limit of 32 km max like the previous RW4 could be? My partner's RW4 can now top out at 40 km/hr on flat ground and hers IS a Canadian market bike., no wind. I see in video reviews they mention the class 2 top speed on throttle or peddling being 20 km/hr, but class three being 32 km/hr - I'd like to have 40 km/hr on throttle as well.
