I have just added a Go+ system to my Dawes Galaxy tourer. I am 68, and was finding hill climbing with luggage increasingly difficult. The Swytch hub now makes quite steep hills a breeze, even in a higher gear. On the negative side, it took 9 months between placing the order, and receiving the kit. In terms of ther installation process, the new wheel and hub slotted in with no adjustments. The problematic part was fitting the pedal sensor, as my Shimano crank is and unusual design, and there is virtually no space between the crank and frame, so the standard sensor was incompatible. Bartosz in CS was very helpful in supplying the other two options, and I was able to untilise the univeral fitting which is a little cludgy with cable ties, but does the trick. The other thing to be aware of, is that the OLED display and control will only fit onto a 22mm bar and mine is much thicker. I was able to get round this by attaching it to the bar extension that I use for my phone/GPS.
