I used the R2 remote a fair amount. Applying pressure to the break overrides the throttle. In the hand it was comfortable but I wasn’t a fan of the split break and throttle.
It was also extremely unreliable with constant communication drops which lead to what I could only describe as input lag. Going along and trying to break, nothing would happen so you improvise (swerve) and then a few seconds later the breaks come on full from your previous request.
The magnetic trigger also needed calibration on every third or fourth ride, I just got into a habit of calibrating it before every ride, quite a pain in the ass. Uncalibrated the remote would not switch speed modes, break or throttle would not work or work on full with zero arc.
If they can iron out these pretty serious issues and we could look past the split button setup I’d say it’s a good option. If they outright clone evolves remote it’ll be terrible.
