Just checking in. After about 6-weeks of daily use...at least 20-miles a day. Weekdays hitting 30MPH for short bursts, and cruising at about 25MPH in Touring-mode, weekends moderate off-road/trail riding, all in mixed and harsh weather, I can say I am well pleased not only with the FatSix, but also the Bikespeed-RS. Incidentally, I keep my HaiBike almost exclusively stored on my trailer-hitch when not in use; it has been inadvertently exposed to some rather harsh conditions, but its accessories, and ESPECIALLY the Bosch motor and the RS have been working like champs. Bosch did a great job in designing a rugged package that protects the delicate innards. The only problems I've experienced are two popped chains, and chain-skipping at higher gears. The skipping seems to disappear after the chains become broken-in though. I can only imagine that the load I'm applying is beyond the expected limits of the design. I weigh about 270#, and the skipping occurs on the top two gears under load in Touring-mode and above. I'll let you all know if it still happens after I loose 20#!
