The Dyname 4.0 is a brand new motor. It has been developed by Rocky Mountain, and it can only be had on their ebikes. We quite liked the Dyname 3.0, but it was getting old. It was a bit chunky and heavy compared to the competition. The Dyname 4.0 is a much more lightweight and compact motor. Check out the video for all the details.
We forgot to mention “walk assist” in the video. It’s there, and it works well. Push and hold the lower button on the remote to access it.
