I am not exactly a newbie but needed to reinitiate my membership so I can log on with my Smart phone I have a Carrera hardtail mtb , China girl 66cc, SBP exhaust, upgraded the electrics with a Wonderful Creations 12v magneto so now running mr16 x4 led front light and an led rear. Bought a chain tensioner upgrade kit, which as been great (cannot remember company I bought it from). Brooks Flyer sprung saddle. That's pretty much it, think next upgrade will be the shiftkit judging by what everyone on here says about them Will try and post some pics of the bike if I can work out how to do it?? Cheers, Pete.
