As you may know, I added a 1000w front hub motor to my Rad Runner. I began to have some concerns about the strength of the dropouts, which appear to be cast aluminum, and are not very "meaty". I read some other reports where it may be unsafe to install a hub motor EITHER on a sprung fork front end, OR on a fork which was not designed to handle one. So I ordered 2 of these, and bolstered up the dropouts, and feel much more secure. I would probably install at least one even if I did not have a suspension fork OR a hub motor up front! Inexpensive and easy to install!
If you are curious, the red thing is a twist handle for a hose clamp, and the steel rod coming up from the left and under the clamp is my fender strut.
