Hi. Just had a quick look at your frame. I have built a few rear and full sus bikes and all have proven difficult. Try to get the rear adjuster to provide full lockout if going ebike unless you have a very successful kit to work, if you go on uneven ground you will get the controller to shimmer the amps and could cause it to overheat ( the bike will feel like you are throttling on and off very quickly ) battery damage would be caused also. If you are going rear wheel as I hope you are then I see no place for hub torque arms, so a little fab may be in order unless you use a reverse dog leg ( I will find supplier later ,I may have some in stock ). Take care in the rear stem carrier as most factory ones only go to 7-10 KG, your kit will be more than this but on bumps will more than double with the energy given, you will need a 30kg proven rack. personally I think the full sus do not really function on ebikes in my experience and when I have attended the shows, most stay away as further problems do occur . I do like what you are doing and will help, however this topic for you bike would have to be done off this forum as its not C5 related. good look though. M
