E-Bike Parts: chargers, batteries, controllers, brakes, tires and more

Replacement parts are where mistakes get expensive. Each category explains how to identify what you have (voltage, connector, size, mount) before you buy. If your bike is misbehaving and you are not sure which part is at fault, start with an E-Bike Assessment instead of guessing.

52V 20Ah Hailong Downtube Battery (generic)

A 52V 20Ah pack is what people buy when they want more range and a little more punch from a bike or conversion kit that can tolerate it. The 52V nominal (58.8V full) is a drop-in for many 48V controllers whose capacitors are rated for it, but not all, so this is an upgrade that requires confirmation. At 20Ah the pack is long and heavy, usually in the taller Hailong-3, DK or Jumbo Shark style case, which will not fit every frame triangle. Measure your downtube clearance before you order and expect to also buy a 52V charger.

Best for: Riders who want a long-range upgrade on a compatible 48V/52V system · Mid-drive kits (BBS02/BBSHD) that accept 52V · Larger frames with room for a long downtube case

52V 2A E-Bike Charger, 3-Pin XLR Plug (generic)

A 52V pack needs a 58.8V charger, and the 3-pin XLR plug is the most common fitting on the 52V Hailong and rack packs sold to kit builders. Mixing this up with a 48V charger is a classic mistake: a 54.6V charger will leave a 52V pack permanently under-charged, while a 58.8V charger on a 48V pack is dangerous. This generic 2A unit is the slow-and-steady option; heavier packs may benefit from a 3A or 5A unit if the BMS allows it. Confirm the XLR pin assignment matches your battery before the first plug-in.

Best for: 52V Hailong or rack-mount packs with an XLR charge port · BBS02/BBSHD builds running 52V · Riders who lost or wore out the original 52V charger

Bafang BBSHD 48V/52V 1000W Mid-Drive Conversion Kit

The BBSHD is the BBS02's bigger sibling: a 1000W nominal mid-drive with a beefier case, a 30A controller, and a reputation for taking abuse that the BBS02 would not survive. It is the pick for heavy riders, cargo hauls, steep terrain, and fat-bike conversions, and it is happy on 52V packs. The trade-offs are weight, a wider Q-factor at the pedals, and more chain wear than any hub motor. Like the BBS02, it ships as a kit without a battery and needs a threaded bottom bracket shell in the matching width.

Best for: Heavy riders and cargo conversions · Fat bikes (100/120 mm shell versions) and steep hills · Riders who want more headroom than a BBS02B
