📐 Battery Fitment Templates
Not sure a battery will fit your frame? Print our actual-size templates, cut them out, and hold them against your frame triangle to check clearance before you buy.
🔋 Battery Mount Compatibility / Interchangeability
Every battery ships with its own mounting bracket, and many packs share the same Shark mount so you can swap freely. Here's which brackets interchange and which are unique.
📐 BBS02 & BBSHD Motor Fitment Templates
Print our actual-size mid-drive and front-hub templates, cut them out, and test-fit them on your frame to confirm the motor fits before you spend a dime.
🏖️ Cruiser Bike & Beach Cruisers
Most beach cruisers convert beautifully, but watch for American bottom brackets, welded chainguards, and battery mounting before you order.
🔌 Front Hub Motor Cables & Length
The stock cable lengths for the 500W front hub kit, so you can tell whether long or stretched frames like trikes and recumbents will need extensions.
🏔️ Full Suspension Bike
Full-suspension frames convert well, but the moving rear end adds motor and battery clearance checks a hardtail never has. Here's what to verify.
🚲 Hardtail, Fixed Fork & Standard Bike
Standard diamond-frame bikes are the easy case for our kits. Confirm a threaded 68 to 73mm bottom bracket or open 100mm dropouts and you're set.
🧩 Other / Exotic Bike Types
Handcycles, unicycles, wheelchairs, and other one-of-a-kind rides fall outside our standard guidance, so here's our honest advice on a custom build.
🛋️ Recumbent Bike
Recumbents convert well but need more time, prep, and usually extension cables thanks to that long, laid-back frame. Here's how to plan the build.
🛞 Replacing the Tire on Your Front Hub Motor Kit
Your front hub kit arrives with a puncture-resistant Maxxis Pace tire already mounted, and here are the rim specs you need to choose a replacement.
🛣️ Road Bike
Road bikes can be converted, but tight clearances and drop bars make them our trickiest standard case. Here's what to check before you order.
👥 Tandem
We don't recommend or support motor kits on tandems. Here's why mid-drives won't work and why a front hub isn't rated for two riders.
🛺 Trike
Trikes are a very doable custom project, but plan for extension cables and creative mounting on that long, stretched-out frame.
🔌 Will I Need Extension Cables? (BBS02 / BBSHD Mid-Drive)
Standard bikes usually don't need extension cables, but trikes, recumbents, and other stretched frames often do. Here are the stock mid-drive lengths.

📐 Will the Bafang Mid-Drive Motors Fit on Your Bike?
