I have had my 2018 Jam2 for a couple months now and love it it feel really sweet the bike I got off of is a 2018 Intense Carbine 29er es. I ride a trail near my house that takes me on my Intense carbine 1:45 to complete its a small mountain 6 miles of climbing then a nice down hill the focus set in its lowest setting changed my time to 1:08 it really fills nice on the climbs it reduces the need to stand up and grind and I love the extra weight on the down hill it fly's. I will say the next setting fells like a your really cheating and its the off road setting to fast for me and the 140mm travel feels almost like my carbine. I am 55 years old and been addicted to mtb for around 30 years I am 6'2" 230 lbs so a the weight fells perfect I tested at a e-bike shop and was amazed the ran out of xl size so went home and found a deal on ebay it had 40 miles on it so I guess its was used

Could of had better components but so far all works good
