In this video I break down my picks for the 5 best electric bike conversion kits, focusing on what actually matters when you’re upgrading a normal bike: motor type (hub vs mid-drive), torque, speed potential, frame compatibility, and how painful (or painless) the install is. I cover options that make sense for city bikes, mountain bikes, touring setups, and even road bikes—plus I call out the key measurements you need to check like dropout width and bottom bracket size before you buy. I start with the BAFANG G020 hub kit as a practical, cost-effective commuter-style upgrade with solid torque, broad wheel-size support, and safety cut-off brake levers. Then I get into the Tongsheng TSDZ8/TSDZ2B mid-drives, which I like for their torque sensor feel—assistance responds to how hard you pedal, so it rides more naturally. For riders who want strong climbing and balanced handling, the Bafang M315 mid-drive brings that mid-drive punch with multiple riding modes and chainring options. If you want flexible power levels and hub choices, the Okfeet kit gives a lot of configurations. And if you want an all-in-one front-wheel swap with app customization, the iMortor/IMOTOR 3.0 is the “smart” option with a detachable battery and phone holder charging.
