The trickiest bit is to fit the pedal sensor but help is at hand! You need to turn the bike upside down, take a picture of the bottom bracket area and email it to support. Andy will make sure that you get the exactly right pedal sensor for your bike. If any tool is required, he'll send you a link to get it from the net.
If you convert your Norco Indie 4, it has a straightforward Shimano UN26 BB, we only need to see that it is long enough to leave a clear 5mm gap between itself and the left crank to take a left side pedal sensor. If not, you need to fit the conventional right side pedal sensor. We would then supply a 3D printed mounting piece to fit your bike. The next difficult bit is to fit additional one or two M5 rivnuts to strengthen the support for the weight of the battery because you ride on gravelled roads. The rest is fairly straightforward. For the rear wheel, you can order the 700C wheel with an 8-speed cassette pre-fitted. Just take the old wheel out and shove in the new one.
Sorry about that, the 700C wheels arrived just before we broke off for XMAS holiday, I forgot to update the web page. It's now shown.
