Good news: this is the easy case. Standard diamond-frame bikes — hardtail mountain bikes, fixed-fork hybrids, commuters, and most everyday bicycles — are exactly what these kits are designed for. There's not much extra to think about.
Just confirm the two universals:
- Mid-drive: a threaded 68–73mm BSA/JIS bottom bracket (BBSHD also in 74–100 / 101–120mm). Press-fit shells need an adapter.
- Front hub: open 100mm dropouts, plus a torque arm on aluminum/carbon forks.
