Are there any Phatmoto owners here?
I have been gathering parts for one of my pet projects; adding gears to the pedal system. I have found the single speed front and rear sprocket arrangement does not always meet my needs, as one of my interests in bike riding is gaining exercise and when I am chugging along at 35 KPH my legs won't move fast enough to input any pedal power, so I am left with just ghost pedaling along.
At this point I seem to have the right crank and chain rings solved by welding my cut down Phatmoto sprocket with crank arm to the front sprocket arrangement from a junked 21 speed mountain bike but the front derailleur is just not working because the down tube is of a fatter diameter than my junk bike and because of the wide pedal arrangement of the Phatmoto it wouldn't work without an extension arm. Got a 34.9 mm Front Derailleur adapter clamp on EBay which fits snugly over the down tube and serves as an extension arm for attaching Derailleur. By grind off the end of the attachment lug the joint well now transfer bending and the assembly stays firmly in place.
An 8 speed mountain bike chain proved to be just about the correct length to work with the 3 speed front sprocket arrangement and the chain tension er went in place without much trouble as did the shiftier, cable and tube.
The next step is to test and adjust the setup to see if it actually works.
