Electric Bike Chainrings: Which One Should You Choose?

Chainrings are the toothed gears at the front of an electric bike by the cranks. They determine the tradeoff between power and torque. Chainrings are an especially important factor when building your own DIY mid-drive electric bike. If you're planning on using your electric bike on very steep hills, you'll need lots of power and torque. You'll also need to pay attention to how your chainring will fit your specific electric bike. For example, if you have a BBSHD, you'll need a specific BBSHD type chainring or a normal chainring with a BBSHD adapter.

Chainring size: The number of teeth on the chainring affects the speed and power of your electric bike

If you're planning on using your e-bike on very steep hills or off-road, you're going to need lots of power and torque. In this case, you should opt for a smaller chainring. For example, if you have a 1000w bike with a 52v 13.6H battery, you can achieve speeds of over 18mph with a 42-tooth chainring.

On the other hand, if you're looking to increase your top speed, you should consider a larger chainring. However, keep in mind that a larger chainring may not fit your bike. For example, a 42-tooth chainring may be too large for certain bikes, such as the 2019 Giant Stance e+.

When choosing a chainring, it's also important to consider the type of connecting screws your bike has. If you have a BBSHD, you'll need a specific BBSHD-type chainring or a normal chainring with a BBSHD adapter. For e-bikes with normal cranks, you'll only need a normal chainring. Additionally, ensure that the size of the chainring won't cause a collision with your bike.

Chainring compatibility: You need to know what type of connecting screws your electric bike has to fit the right chainring

Chainring compatibility is an important factor to consider when choosing an electric bike. Chainrings are the toothed gears at the front by your cranks, and they determine the trade-off between power and torque on your bike.

To fit your chainring to your electric bike, you need to know what type of connecting screws it has. For example, if you have a BBSHD, you’ll need a specific BBSHD type chainring or a normal chainring with a BBSHD adapter. If you have an e-bike with normal cranks and a motor on the front or rear wheel, you’ll only need a normal chainring.

You should also consider the size of the chainring to ensure it won't cause any collisions with your bike. For instance, if you're planning on using your e-bike on very steep hills, you'll need a larger chainring for more speed, such as a 42-tooth chainring. On the other hand, if you want more power and torque, you should opt for a smaller chainring.

Additionally, you might need to purchase chainring bolts separately, depending on the model of your bike.

Chainring bolts: You might need to buy some chainring bolts separately

Chainring bolts are an important consideration when choosing a chainring for your electric bike. While some chainrings come with bolts included, others do not, and you may need to purchase them separately.

The type of connecting screws your chainring has will determine how it fits to your electric bike. For example, if you have a BBSHD, you will need either a specific BBSHD type chainring or a normal chainring with a BBSHD adapter.

If you opt for a normal chainring, you can simply get 5-bolt chainrings like the FSA Super Road Chainring or the SRAM Alloy Road Bicycle. However, you may also need to purchase additional chainring bolts, which come in various colours, including red.

It is important to keep in mind the size of the chainring to ensure it does not cause a collision with your bike. For instance, while a 36-tooth chainring may be standard for some electric bikes, you may find that a larger chainring, such as a 42-tooth, will help you go faster.

Chainring type: You can choose between a 5-bolt chainring and a normal chainring

If you have a BBSHD, you will need a specific BBSHD type chainring or a normal chainring with a BBSHD adapter. For e-bikes with normal cranks, you will only need the normal chainring for your bike.

The number of teeth on the chainring will determine the trade-off between power and torque on your bike. If you are planning on using your e-bike on steep hills, you will need lots of power and torque, so a smaller chainring is best. If you want to go faster, try a larger chainring.

Chainring options: BBSHD adapters allow you to use different-sized chainrings on your electric bike

Chainrings are the toothed gears at the front by your cranks. They determine the trade-off between power and torque on your bike. If you're planning on using your electric bike on steep hills or off-road, you'll need lots of power and torque.

If you have a BBSHD, you'll either need a specific BBSHD-type chainring or a normal chainring with a BBSHD adapter. BBSHD adapters are a great option if you want to purchase lots of different-sized chainrings for your riding.

You can also get 5-bolt chainrings like the FSA Super Road Chainring or the SRAM Alloy Road Bicycle. Just make sure to check the size of the chainring and ensure it won't cause a collision with your bike. For example, if you're using a 1000w motor with a 52v 13.6H battery, you might want to avoid using a 52-tooth chainring up a steep hill.

If you're looking to go faster, try a larger chainring like a 42-tooth. If you want more grunt, go for a smaller chainring.
