Yeah up motor current max break to -75 and yeah try -45 for max regen. Is your battery using a bypassed BMS?

If it’s a discharge BMS becareful with This setting. Too high and you will blow your vesc

Bypassing discharge so we’re good there. I think I was running -60 brakes before I changed it, and it was almost perfect on hills, but slightly overpowered on level ground… my girlfriend fell the other day when she slammed the brakes and it came to an immediate stop.

:joy::joy: cheap stuff, Bridgestone White Zinfandel. Can’t go wrong!

No bite for me. Running BN adjustable baseplates and 270mm hangars. It’s really close during sharp turns, but no contact. I think I’m running 30-40 degrees right now

Was literally just talking to my girl about this. Needs something faster and better on these PNW hills. What bike does your lady ride?

wait – just realized you said on the feet. I definitely rub the wheels on my feet if they aren’t positioned just right. I’m only a size 10 so it’s not bad, hasn’t caused any issues yet.

We have the rad mission

Not the best on steep hills. I would recommend a bike with atleast a 750w motor the 500w here used to make her work on the crazy Oakland hills

You’re cutting off at 2.9V/cell, so that’s probably already pushing it as far as you want to go.

Good to know man, thank you

Make sure you’re charging to full 4.2v / cell, if you want more range. You may not be, if you’ve never checked.

You can also adjust braking feel by adjusting “throttle exponent brake”

Negative throttle expo brake should give you gentle low speed brakes

You should definitely change this to .9 ish.
It will give you a soft end to the top end of your speed. The way you have it can be dangerous when you hit full duty cycle.

Im pushing 120a/ side with Radium 6485’s and my MOSFET temp hasnt got over 55c yet. I was pushing 110a into the flipsky 6384s for about a week and it was fine also but that was like 15a over the factory limit. UBOX is good, as long as its with a puck remote it seems.

This is my throttle curve with the puck remote on the UBOX v2. Also my deadband is set to 3% and its pretty smooth. This map with also 20a regen works nice for me here in NYC, light at the start and really kicks in at about half and total lockup around 70% brake on the thrumb wheel. Also make sure you mapped your remote input properly to get the best performance.

I do this but -20% for the throttle too, with the natural curve.

I see the minor difference in the graph for poly and natural, anyone have a real idea on the difference in feel? I can’t quite seem to tell.
