i also used a pot box on my first bike, a simple and effective solution. on my second bike, however, i'm using a Magura. also had a slight issue with the cable mounting and the controls, so i took apart then end housing of the Magura and cut a hole in the controls then joined the two up. the Magura does still stick out a little bit, but because of the controls i have that little bit lets the mirrors on both side line up better. in short: if i was doing a conversion, like my first bike i would use a pot box and exiting throttle. if was doing a from scratch like my second bike i would use the Magura. that is becuse it was cheaper and simpler than buying a new throttle and pot box when i could get both together in a Magura. also an electric bike is quite different than a gasser in two ways w.r.t. the trottle. first, you don't need a lot of range for up/down shifting. two, the controller is automatictly doing a lot of the veclocity changes for you; even holding the trottle at one point the controller will start off with high amps and low volts then transition to low amps and high volts. personaly i found the large range of the trottle/pot box combo to much of a pain. i'm looking forward to experimenting with a smaller range.

Basically follow down to the end of the cable and mount your box to the frame (or a bracket if necessary) making sure when the throttle cable is fully extended and retracted that the full swing for the pot is used. The closer to the pot pivot the less throttle travel necessary. The Curtis has a spring built in, you can add another exterior spring if throttle does not return adequately. I cut off the lead terminator on the cable and and went to Home Depot and got this part from their hardware section that has a set screw for clamping the cable end and part of it is a pivot to go in the pot arm. I have had zero trouble with it in 1000 miles. Cheers, Jeff On Jan 23, 2008 7:27 AM, SteveS wrote: > I kind of assumed I'd be using a handgrip-type throttle, like the > Magura.
