I have a bafang ultra motor and a push down to accelerate thumb throttle on the left handlebar. It's VERY touchy and difficult to modulate on bumpy roads. I rarely use it because it's a mid drive and I'm trying to get good longevity from the chain and sprockets. The sudden torque on the chain after hitting a bump is not good when using the throttle.. That said, sometimes it's fun to just throttle up a big hill. The bike easily hits 35mph with the throttle but pedaling I can only get to around 25mph before my legs are spinning too fast in 9th gear.

The stock Bafang thumb throttle is a terd and the first thing I replaced on my Ultra and BBS02B bikes.
Since my Ultra bike has a Rohloff twist shifter on the right, I installed a left hand half twist throttle. So easy to modulate just the amount of power desired.

The half twist throttle allows you to wrap two fingers and your thumb around the twist part of the throttle, with the other two fingers wrapped around the grip.
That Really helps to keep your hand and throttle steady when the handlebars are bouncing.
Way less strain on your thumb as well.
