I have rode my first 500 miles on my ssr sandviper a 500 watt fat tire bike. No problems what so ever. One bolt fell out of the rack attachment. I am on the heavy side so I could use more power, but that is not the bike's fault. Great bike.
Sounds great @Soarcj! Try a drop or two of blue loktite on those pesky rack bolts. They're short and always vulnerable to working their way out; the loktite will slow that down but keep the bolts removable should that be needed.
