Mountain bikes have either 68mm or 73mm bottom brackets so find that out when you buy the bike and then order your kit. That is unless the kit comes with adapters for either. The Bafang mid mount kits are a good kit. A buddy of mine installed a 1000 watt one his full suspension mountain bike and that thing flys.
