Best electric bike conversion kits with battery
Researched by Deal.ai's shopping agent across stores on November 7, 2026. Prices below are today's.
Top pick: BAFANG BBS02B 750W mid-drive kit (48V). A mid-drive drives through your gears, so it climbs and pulls a load far better than a hub motor of the same rating, and Bafang is the name most conversion builders trust for parts and support. Best if you want real assist on hills and a bike that still feels like a bike.
Who the others suit:
- eBikeling 36V 500W geared kit — the sensible, well-reviewed choice for a lighter rider on flat-ish routes; geared hubs are small and free-spinning.
- eBikeling 48V 1200W direct-drive — for steady high-speed cruising and long flat commutes; heavier and draggier when off.
- Livall Pikaboost 2 / Pikaboost2 Powerful — a friction-roller unit that clamps on in seconds and needs no wheel swap; ideal if you don't want to touch the bike's mechanics.
- Budget 26" rear-wheel hub kits (ChicHomey, Unbranded, ToppiJoy) — cheapest way in, but check your wheel size, dropout width and battery quality before buying.
Whatever you pick, confirm the kit's battery voltage and capacity, your bottom-bracket width (mid-drive) or dropout spacing (hub), and that the battery is a reputable cell brand.
