Hello everyone, first time poster long time lurker. I've owned many mountain bike's over the year's, my best being a GT avalanche comp. Then I decided to buy a carrera crossfire e, which I was amazed by and hooked from the start. Trouble is 250w motor 15.5 mph isn't fast enough. So I have upgraded go a 1800w 52v bike, haven't taken delivery of it yet but am very excited to see the difference, of course I shall only use that power off road. I've been riding my crossfire and been smoked by two lads on oxygen ebikes derestricted to 22mph. Has anyone got a bike similar they can relate to power comparison wise ??
