Transform Your Bike: Electric Power, Easy Steps

Electric bike conversion kits are a popular way to turn your bike into an e-bike. There are several ways to electrify your bike, including fitting a powered wheel, attaching a drive unit to the bottom bracket, or fitting a motor above the rear wheel. The Swytch system is an example of a universal electric bike conversion kit that uses a motor at the front hub. Conversion kits are becoming more sophisticated and easier to install, making them a practical alternative to buying a new electric bike.

Fitting a powered wheel

To fit a powered wheel, you first need to set up the wheel with a disc rotor, tyre and inner tube and install that into the bike. Then attach the cadence sensor – so it can tell when you're pedalling and need assistance – then attach the battery and the LCD display. It's worth bearing in mind that although this conversion kit comes in many different wheel sizes, it is only compatible with bikes that have a front disc brake and a Quick-Release axle. If your disc brake bike is a newer, more expensive model, it might not be compatible, so it's worth checking first.

Another option is to fit a mid-drive motor, such as the BBS02, which uses the existing drivetrain and augments your bike pedalling with electric power. It does this by spinning the front chainring directly, which then drives the chain and rear gears, spinning the rear wheel and moving you forward. The size of the chainring determines how much torque (rotation power) you get from a specific RPM (rotation rate). A smaller chainring will allow you to accelerate from a stop more quickly and will put less strain on your motor, but will have a lower top speed.

There are an increasing number of e-bike conversion kits out there, and they're getting more sophisticated and easier to install on your bike, making for a practical alternative to a new purpose-built electric bike. Many can even be fitted by a competent home mechanic if you’re feeling handy and have an afternoon spare.

Attaching a drive unit to the bottom bracket

There are several ways to convert your bike into an electric bike. One of the most popular ways is to attach a drive unit to the bottom bracket. This can be done by using an electric bike conversion kit, which will enable you to add a motor to your existing bike. These kits are becoming increasingly popular and are getting more sophisticated and easier to install.

The first step in attaching a drive unit to the bottom bracket is to remove the existing bottom bracket and replace it with the drive unit. This will involve removing the cranks and chainrings, as well as disconnecting the shifters and brake cables. Once the bottom bracket is removed, you can install the drive unit in its place.

The drive unit will consist of a motor, a battery, and a controller. The motor will be attached to the bottom bracket shell, while the battery and controller will be mounted on the frame of the bike. The motor will be connected to the cranks, which will then drive the chain and rear gears, spinning the rear wheel and moving the bike forward.

When installing the drive unit, it is important to ensure that it is securely mounted and that all the connections are properly made. This includes ensuring that the motor is properly aligned with the cranks and that the battery is securely mounted and connected to the controller. It is also important to consider the weight distribution of the bike, as the addition of the drive unit will affect the handling and balance of the bike.

Once the drive unit is installed, you will need to connect the cadence sensor, which will tell the motor when you are pedalling and need assistance. This will be attached to the cranks or the bottom bracket and will send a signal to the controller, which will then activate the motor. Finally, you will need to connect the battery and any LCD displays that come with the conversion kit.

Fitting a motor above the rear wheel

There are a number of electric bike conversion kits available, which are becoming increasingly sophisticated and easier to install. These kits enable you to add a motor to your existing bike relatively cheaply compared to buying a whole new electric bike.

One example of a conversion kit is the Swytch system, which uses a motor at the front hub. Another option is to use a mid-drive motor like the BBS02, which uses the existing drivetrain to augment your bike pedalling with electric power. This is achieved by spinning the front chainring directly, which then drives the chain and rear gears, spinning the rear wheel and moving you forward. The size of the chainring determines the amount of torque (rotation power) you get from a specific RPM (rotation rate). A smaller chainring will allow for quicker acceleration from a stop and will put less strain on the motor, but will result in a lower top speed.

When installing a conversion kit, it's important to first check compatibility with your bike. For example, some kits are only compatible with bikes that have a front disc brake and a Quick-Release axle.

Concealing a motor in the seatpost

There are several ways to convert your bike into an electric bike, including fitting a powered wheel, attaching a drive unit to the bottom bracket, or fitting a motor above the rear wheel. One of the most discreet ways to do this, however, is to conceal a motor in the seatpost.

To do this, you will need to purchase an electric bike conversion kit, which will provide you with the necessary motor and other components. The Swytch system, for example, is a universal electric bike conversion kit that uses a motor at the front hub. When choosing a conversion kit, it is important to consider the compatibility with your bike. For instance, some kits are only compatible with bikes that have a front disc brake and a Quick-Release axle.

Once you have the conversion kit, the process of concealing the motor in the seatpost will depend on the specific kit and your bike's design. However, the basic principle involves removing the existing seatpost and replacing it with the motorised seatpost provided in the kit. This will involve detaching the seat, removing the old seatpost, and installing the new motorised seatpost, ensuring it is securely attached and aligned correctly.

The motorised seatpost will likely require an additional power source, such as a battery, which will need to be mounted on the bike. The specific location for the battery will depend on your bike's design and the kit's instructions. It is important to ensure that the battery is securely mounted and does not interfere with the bike's functionality or your riding position.

Finally, you will need to connect the motorised seatpost to the bike's drivetrain. This may involve attaching a cadence sensor, which detects when you are pedalling and activates the motor to provide assistance. The exact process will vary depending on the conversion kit and your bike's setup, but it typically involves connecting the motor to the front chainring or the rear wheel, allowing it to augment your pedalling with electric power.
