We have threaded adapters for any width bottom bracket from 68mm to 120mm for most press-fit standards. If you have a 68 or 73mm bottom bracket you may have the best results with the one-piece adapter.
PF42 refers to the 42mm inside diameter of the shell. PF42 is used in BB30, BB30A, BB30AI, and BBRIGHT™ DIRECT FIT bottom bracket types.
PF46 refers to an inside shell bore diameter of 46mm. PF46 (PF30, PF30A, PF30AI, BB386EVO, OSBB, BBRIGHT™ PRESS FIT bottom bracket types.
PF41 BB shells have a nominal 41mm inside diameter. PF41 (BB86, BB89.5, BB92, BB107, SHIMANO® PRESS-FIT, PF24 bottom bracket types.
Eccentric BB Adapter - American (Ashtabula) BB shells 51.3 mm (2.02") inside diameter. These are typically found in older American-made bikes and American children's bikes. Some cruiser bikes for the American market still use this style.
Note: (Adapt your bottom bracket to the BSA/JIT English threaded type that mid-drive motors require. Most bikes that originally sold for less than $1500 or are older than 2013 have English threaded bottom brackets and you are good to go. If you have a square tapered spindle for your cranks then you have the required threaded bottom bracket. Around 2012 many higher-end bikes started being fitted with various press-fit bottom brackets many of which can be adapted to English threaded so you can still do a mid-drive motor conversion on them. However, there are some exceptions. For an in-depth article on adapting various bottom brackets and the exceptions see this thorough article by Matt Hughes.)
EBC recommends using Loctite 641 or other sleeve retaining compound on the adapter and on the inside of the BB shell case before installing to help keep the bottom bracket solid and to keep some motors like Bafang from rotating. Use Loctite 7649 spray for a quick set if you are going to ride it the same day.

Mounted the 46mm two piece adapter on a Seven Ti single bike bottom bracket. Used a Park Headset press in order to achieve the perfect alignment pressing one side each time. The exterior flange on the adapters did not interfere with the chain line. Nice product when need to adapt a BBS02.

I needed a BSA bottom bracket for an ebike build on a Specialized Crux which had a BB30, so this adapter was perfect. It was sized accurately and, with a little encouragement, slid in just fine. Highly recommended. Price was right, too!

"DOWNLOAD OUR SUPER SHARK FITMENT TEMPLATE
Super-Shark e-bike battery. 52v 14AH 40 amps continuous*. 8.5lb. What's new? This 52v e-bike battery is easier to mount and stronger all around. The cells are mounted more structurally sound within a honeycomb lattice. The case and mount tabs are thicker, and the case is reinforced with an internal lattice. The mini 3-pin charge port is much stronger and an on-off switch has been added.
The Shark style is extremely popular because it is sleek and looks great. 52V 14AH e-bike downtube battery with high capacity Samsung 35E cells and 40 amps output. Removable battery locks to down tube for security. This sleek battery packs over 700 watt-hours into a tight and attractive package. That is 200 watt-hours more than Bosch or Yamaha. The Super-Shark is a ruggedized upgrade to the proven and popular Shark battery.
The cells in this battery are high-quality Samsung 35E or Panasonic GA high capacity 3500mah cells. We only use Grade-A, Certified Genuine Panasonic/Sanyo/Samsung/Molicel cells.
UN38.3 safety certification.
2 amp, 4 amp, 1-5 amp, and 80/90/100%-charge, charger options.

More info about Electrify Bike 52v batteries:
Batteries from Electrify Bike Company utilize the latest, 21700 cell technology from the leading brands making safe Lithium-ion cells. The cells we use are all top-of-the-line high-capacity/high-power cells from Samsung, Panasonic, Molicel, and LG. You won't find batteries of the same size with higher capacity because we use the highest capacity cells available in all our batteries.
The cells are more expensive but worth it in performance and peace of mind. Using high-quality cells, BMS, and build quality, ensures that our batteries are as safe as possible. We still use 18650 cells in our low-profile Super Shark battery to keep it as low-profile as possible to fit in more frames.
All our 52v batteries except the Super Shark can deliver an astounding 50 amps of continuous power. That is over 2500 watts! Very few motors use anywhere near that power, which means the battery will run cooler and last much longer than a battery rated at or near the same power as the motor.
52v batteries are the most popular batteries we sell, and they are often the best choice for 48v motors, including batteries for Bafang BBSHD, BBS02 48v motors, and Tong Sheng TSDZ2 48v motors. They are also the most popular battery for CYC Photon, X1 Stealth, and X1 Pro mid-drive motors.
Here is an article providing information on 52v vs. 48v batteries.

52V 50 amp 10Ah Mini-Max Lithium-Ion Ebike Battery with genuine Samsung 50S Cells. This battery is ultra-light (4.6 lbs), ultra-compact size at (3.75" X 3" X 6.75"), and versatile. Delivers 50 amps in a tiny package and was designed to fit perfectly in our optional EBC saddle bag tucked away under your seat. This 52v e-bike battery is a great compact high-capacity choice, and it looks good too!
Combining the Mini Max and optional saddle bag allows you to mount the battery anywhere on your bike frame using the optional EBC Flex Mount. It fits inside the triangle on many full-suspension mountain bikes or even under the down tube. You can also double them up using our EBC Dual Battery Module to double the capacity and double the amps. Put one under your saddle and one on the frame. Imagine 100 amps and over 1,000 watt-hours out of two of these compact batteries.
The cells in this battery are high-quality Samsung 21700 50S cells. Electrify Bike Co. inspects and certifies that these are genuine Samsung cells. Due to the high output of this pack, it only comes with an XT90 connector.
90% of e-bike trips are less than 10 miles. So why lug an extra 5-10 pounds 90% of the time if you don't need it? For the other 10% or when you need more range, take along a spare Mini-Max!
These mini-max batteries are also great for spare tanks when used with a larger battery. If you ever worry that you may not have enough juice to get you to your destination or back home, take one of these along to extend your range or give you peace of mind.
