You’ll learn how to pick a conversion kit that fits your frame and riding goals, how to install (especially mid‑drive), how to avoid the most expensive mistakes, how battery upgrades affect range, and what “legal” typically means in the US once you convert.

Quick decision rules (copy/paste friendly)
- If you ride steep hills often: mid‑drive usually wins for climbing feel (at the cost of more install complexity).
- If you want the simplest install: hub‑motor kits are typically easier and faster.
- If your bike has limited frame space: confirm battery mounting before buying a big pack.
- If you’re converting for street use: build to match Class 1/2/3 limits and your local rules—don’t assume “anything goes.”
- If you care about reliability: budget for brakes, tires, and drivetrain wear (power upgrades stress these parts).
Common mistakes (money + safety)
| Mistake | What happens | Better move |
|---|---|---|
| Buying a kit before checking frame/brake compatibility | parts don’t fit | verify frame, wheel size, brakes, dropout spacing first |
| Overpowering a weak bike setup | broken spokes / poor braking | upgrade contact points (brakes/tires) before power |
| Battery/charger mismatch | poor performance / damage risk | match voltage, chemistry, and charger spec |
| Rushing wiring & connectors | intermittent cutouts | strain‑relief, weatherproofing, tidy routing |
| Ignoring legal/class limits | tickets / access issues | follow class rules + local policies |
