Skip Beattie's Bike
Pic 1 (Clamp...) shows how the unit was mounted on the left down tube using an "off the rack" clamp.
Pic 2 (control...) shows the control box location inside the R/H side cover. Nice, clean and easily accessible.
Pic 3 (side..) gives an overall view of the installation
Pic 4 (Back...) is me, grateful to be riding again!
