Hi folks , can anybody help me. I have a oxygen mtb mk 1 ebike, I have a bit of play in the bottom bracket , I have had a few problems probably wear and tear using the bike allot. I have ordered a new chain and a new crank because of noises and slipping going up hills but when fitting a can rock the bottom bracket a little when crabbing the crank arms when checking for play. Does anybody think the bottom bracket wants tightening or best getting a new bottom bracket . If so does anybody know what size I need , I have not got the tool to remove it yet so I want to order it as soon as possible ready for the summer pub runs . Thanks for your kind help.
