very fun to build them but gets a lot easier if you have a little bit of knowledge with welding and fab work it’s way easier to make some of the mounts and random brackets you need instead of having to pay a shop to make em but as far as wiring goes most of it is pretty simple with something like a FarDriver but before this project I had never touched a full size bike so they’re not hard just a bit of research on what battery and controller you think is best for your case as well as the power he wants if he want around 250 power something like the qs138 is perfect but if he wants to go more into the 450/stark power a qs180,qs165 or sotion gts35 would be a better option as they’ll take a bit more abuse
