Are you wondering how to put a motor on a bike? Don’t worry; we’re here to help you.

Isn’t it wonderful to be able to jump on our bikes and ride around the city?

We can do it without having to spend a lot of money on a car or a scooter! Installing an electric motor kit is the best option for individuals who want to drive fast without exerting any effort.

With this step-by-step guide on how to put a motor on a bike, you’ll learn how to install the kit on your own, how long it takes, and how simple it is.

Let’s start learning.

How to Put A Motor On A Bike?

You’ll save a lot of time and money if you know what you need to know before installing a motor on your bike.

Below is a step-by-step guide to the complete installation process.

Gathering the Tools and the Equipment: What Do You Need?

• Electric bike starter kit
• Screwdriver
• Socket wrenches in a set
• Wire cutters and strippers
• Wrench
• Pliers

Step 1: Unpack the Electric Bike Kit

Skip to the next stage if you bought one that was already built.

Take everything out of your packing box or bag and double-check that you have everything you need to put a motor on a bike step by step.

Step 2: Mounting the Pedal Assist Sensor

Skip to step four if you bought a pre-assembled kit.

This is one of the most crucial steps. You can’t put it on later since it will break down your bike.

Remove any pedals that are currently connected to the crank of your bike.

Unscrew the bolt holding the crank arm to the frame of your bike with a tool or pliers.

Once the pedal assist sensor is attached to the free end of the crank arm, re-secure it with the same bolt that was used to remove it (this may take some muscle).

Then tighten the bolt completely.

Step 3: Mounting the Speed Sensor

Skip to step 5 if you bought an assembled kit.

This item is simple and contains an “L” shaped bracket that can be placed at the front wheel axle on almost any bike frame. Several bolts may need to be removed at this part of the procedure.

To secure it, tighten the top screw and wedge it into the frame of your bike so that one side is firmly on the axle.

Step 4: Mounting Torque Sensors (if needed)

If you bought a torque sensor kit for this part, attach it to the handlebars of your bike (one on the right, one on the left).

It will be necessary to remove bolts and then screw them back in with an Allen key.

Tighten each bolt until it is securely fixed, but not to the point of causing damage.

Step 5: Mounting the Controller (if needed)

If you bought a kit without a controller, skip this step and go to Step 6.

If one came with your kit, you’d have to unite the two parts with an Allen key before attaching it to the motor’s throttle.

Overtightening with an Allen key can cause the controller to shatter, so use caution when attaching it.

Instead, check them using a Phillips screwdriver to ensure they’re secure but not overtightened, as this could cause the torque sensors to fail.

Step 6: Mounting the Throttle

Skip this step and go to Step 7 if your kit comes with a throttle.

If the manufacturer did not include the screws, you might need to mount it with an Allen key. Make sure you’ve secured it with your hands before tightening anything else with a Phillips or Allen key.

Step 7: Mounting the Brake and Gear Levers

You might get a gear shifter with your kit, but if not, you can get one separately. To secure it to your handlebars, use an Allen key or Phillips screwdriver. They’re prone to breaking if you overtighten them.

Next, attach the brake levers. These are usually bare metal and may need some touch-up painting to look decent (this is optional, though).

Make sure they’re securely secured with a Phillips or Allen key before continuing on.

Step 8: Mounting the Drive Pulley Wheel(s)

Your package may include a second, smaller belt wheel for your rear tire. This provides the bike with a scooter-like feel and helps you get rolling after pushing off with both feet (just like regular bikers).

Reattach them with a Phillips or Allen key before continuing.

Step 9: Mounting the Controller

Your package may contain a bracket for installing your controller. This is the spot to put it if that’s the case.

Otherwise, secure it with zip ties or Velcro straps if one isn’t available. Check to see if any ventilation openings are blocked.

Step 10: Wiring

After your motor has been properly installed, you can connect the cords to it.

First, connect the controller to the motor (this is the large connector).

Check to see if these two sections are in the right place. It’s simple for them to mismatch and results in a faulty connection if you connect them backward.

Once you’ve made the proper connection, tighten the screws holding them together using a flat-head screwdriver.

Connect your battery connector after that (the smaller one).

As with the controller connection, do not misalign these components and secure them in place before proceeding.

After that, the wires can be zip-tied or Velcro-strapped to your bike’s frame.

Finally, you may attach a throttle and brake wire to your handlebar grip shifter.

Conclusion

So, how to put a motor on a bike? There’s a lot more to getting your bike up and going, but these steps should get the motor up and running.

If you become trapped, you can also seek help from a nearby mechanic. Aside from that, this is a straightforward method to master.
