Recently I have been longing for a mini fender on my MotoLite. Titus does not offer one so I decided to make my own and share my results. I modified a Specialized Stumpjumper MudFlap Shock Protector (part number 9894-2300). I first held the fender up to the bike with the clip on top of the seat stay yoke. I eyeballed where the cable housing was and then used a round file to create a bridge under which the housing could pass. I then secured the fender with 3 zip ties through the holes on the fender. I have yet to ride it but it is very secure to the frame and I expect no issues except perhaps some mud build up through soupier sections.
I hope someone out there finds this helpful.
