Just a chance to compare experiences if you don't mind sharing ? Crossfire e with the Suntour drive system, around 6 months old now, done 1350 miles . No sooner I'd brought it I found out the Suntour system does suffer with occasional cut outs...and mine has done intermittently but not too much to cause concern. No idea how the battery is doing, it does what it says it will...I'm Intrigued what life folk actually get from their batteries.(before they start to fail) The crossfire has done well, very good brakes, no mechanical hiccups, a very well built bike IME.
