1. BAFANG FRONT HUB MOTOR KIT

 

BAFANG FRONT HUB MOTOR KIT

Bafang is a well-established maker of electric bike motors and offers a front hub-based motor if you’re not a fan of the bulky profile a mid-motor conversion system creates.

You can buy this kit without a battery – although why would you? – but if you sensibly also opt for a power-pack there's a choice of amp hours, and you can select either a downtube or a rear-rack mounted version.

4. SWYTCH UNIVERSAL EBIKE CONVERSION KIT

 

Best bike conversion kit for simple fitting

 

SWYTCH UNIVERSAL EBIKE CONVERSION KIT

 

The Swytch system is one of the simplest conversion kits to fit out there and yet is still amongst the cheapest. The motor sits in the front hub and is pretty discreet, while the battery pack sits in a bag that connects to the front of your handlebars.

This setup makes it one of the most straightforward front-hub conversion kits currently out there, although it does mean the battery size is a little lower than other systems which mount the battery in the main triangle or a rear rack.

Like the Bafang mid-drive system, the TongSheng offers the same benefits of compatibility with a wide range of bike designs and a high torque for steep hills and off-road terrain. However, the TongSheng mid-drive does manage to be a little lighter than the Bafang for approximately the same power.

SPECIFICATIONS

Torque: 80nm

REASONS TO BUY

+Lightweight for the power output 

+Compatible with a wide range of bike designs

+Better ground clearance

Benefits of choosing cheap electric conversion kits, taking Esoulbike as an example

 

Are cheap electric bike conversion kits any good?

Just because something is cheap doesn’t necessarily mean it isn’t any good. I have converted countless bikes using budget 500w and 1000w rear-wheel electric conversion kits and I have had very few issues.

Points that need to consider when buying a cheap e-bike conversion kit

 

Now that you know a bit more about electric bike conversion kits, let’s go over what factors you should consider before buying one.

There are six main compromises to consider when buying a cheap e-bike conversion kit.

cheap e-bike conversion kit

 

1. Motor Type

 

There are three main types of e-bike conversion kit motors: front hub, rear hub, and mid-drive. The type of riding you do will largely determine what type will be best for you. Front and rear hub motors are relatively easy to fit and maintain.

cheap e-bike conversion kit

They also place less strain on your bicycle’s drive system. They’re great options for commuters who want to lighten the load on their way to work or simply get around faster. But you could be restricted in terms of what parts you can use, especially when it comes to tires, rims, and cassettes.

cheap e-bike conversion kit

Mid-drive motors also work well for commuting, but where they really stand out is off-road. You’ll be able to use whatever chain, cassette, tires, and rims you like, but they’ll need to be heavy-duty to withstand the motor’s torque.

2. Output

 

The next thing you should consider is how much power you’ll need. The two figures to consider are watts and newton meters of torque.

How many watts an e-bike motor has is similar to how much horsepower a car has. The power output of an electric bike conversion kit is usually measured in watts. The higher the wattage, the more powerful the motor will be.

cheap e-bike conversion kit

The continuous wattage is how many watts the motor can sustain continuously without overheating. If you’re just looking for a bit of extra help on your commute, then a 250-watt motor will probably suffice.

But if you want to go off-road or tackle hills, you’ll need at least 500 watts. Anything more than that is overkill for most riders.

3. Controller

 

The controller is the brains of the electric bike conversion kit. It regulates how much power goes to the motor. Most controllers these days are programmable, which means you can customize how they work to suit your riding style.

cheap e-bike conversion kit

For example, you can set the motor to provide more power at lower speeds or less power at higher speeds. You can also usually set a limit on how much power the motor can draw from the battery.

4. Battery

 

Some kits come with a battery, but many don’t. Even the kits that come with a battery usually have several options to choose from, so you’ll need to decide which one best suits your needs. The larger your motor is, the faster it’ll drain your battery.

cheap e-bike conversion kit battery

To figure out how many watt-hours a battery has, multiply its amp hours by its voltage. For example, a 48-volt battery that’s using a 10-amp-hour controller will be 480 watt-hours.

cheap e-bike conversion kit battery

If you’re using a 500-watt hour battery, it can deliver 500 watts continuously for one hour or 1,000 watts for 30 minutes, etc. Of course, if you use the pedals and a low motor assistance setting then, you’ll extend the battery life.

To determine the right battery for you, you need to consider the size of your motor, how long you ride each day, and how much assistance you want from the battery when pedaling.

 

5. Sensor 

 

You’ll encounter two main types of e-bike sensors: cadence and torque sensors. Cadence sensors detect when and how fast the pedals are moving via a sensor at the crankset.

These sensors will apply a proportional amount of power from the motor relative to how fast the pedals are moving. Although these models are cheap and easy to fit, they can have jerky power delivery that feels unnatural.

Torque sensors deliver power depending on the force of rotation applied to the crankset. These sensors feel a lot more natural, especially when ascending or descending steep hills.

Some riders even forget that they’re being assisted by the motor. When compared to cadence sensors, torque sensors can even extend the battery’s range, as they only deliver as much power as needed.

 

 

6. Compatibility

 

Before buying an e-bike kit, you need to make sure it’s compatible with your bicycle. If you’re buying a front or rear hub motor, make sure the dropouts are wide enough to accept the electric motor and that the motors will work with the type of brakes your bike uses. Some rear hub motors won’t work with anything larger than a 7-speed cassette.

 cheap e-bike conversion kit

If you opt for a mid-drive motor, make sure that it’s compatible with your bicycle’s cassette and the diameter of its bottom bracket. Manufacturers list the diameter that their motors are compatible with and (normally) have options to fit various cassette sizes.

Mid-drive motors also put considerable stress on your bike’s drivetrain and frame so, if you want a powerful motor, make sure your bike’s components are suitably durable.
