1: 46mm wheel nut side/ 41 mm sprocket side/ 28mm front wheel 2: The tool for the hub should be in the tool kit...looks lke a large C spanner with a box section piece for the handle. 3: Torx 7 I think? 4: No problem with connecting up a charger to the battery...have optimate terminals on mine. 5: Tyre pressures are a personal thing...but 36 psi front and rear will put you close. Theres a great post by shazzam somewhere on here about tyre pressures and working them out to suit your riding style. Try a search on it. HtH |
