How to Convert Cruiser Bike to Electric?

You can convert cruiser bike to electric by fitting it with an e-bike conversion kit. These conversion kits allow you to add a battery, motor and electric controls to a non-electric, conventional cruiser bike. If you choose the right conversion kit and take care to install it properly, the new e-bike will let you cruise around with minimal pedaling for longer durations.

Steps to Convert Cruiser Bike to Electric

Here are the simple steps to follow to convert your conventional bike to an electric bike:

1 – Swap the tire and tube

The first step is to remove the tire and tube of the current front wheel. You will then need to install the tire and tube on the new wheel from the e-bike kit. Make sure that the tire is directional and mounted such that the cable is sticking out of the hub on the left-hand side when the wheel is installed. Else, the wheel will work in the opposite direction.

Get some tire levers and a pump to remove the tire and tube. Finally, you will need to tighten the nuts on the wheel’s axle to hold it firmly in place between the forks. Make sure to fix and adjust the brakes correctly for the new wheel.

2 – Fix the Bracket to Handlebars

You will find a strap that needs to be fixed to the handlebars so the bracket stays firmly in place and does not rotate with gear-change. You can find some adaptors included in conversion kits which can be used if your handlebars are thinner.

All you need to do here is to simply tighten a couple of screws to fix the bracket firmly to the handlebars.

3 – Fix the Magnet Disc and Sensor

The next step involves fixing the magnetic disc. This disc has a split design so it can be simply clipped around the inside of the non-drive side crank. A retention ring is then used to hold the magnetic disc in place.

Next, you will need to install the sensor on the frame, accurately in line with the magnets. This way, the sensor knows when the cranks are moving.

4 – Plug in the Cables

The main power cable is the thickest one in the e-bike conversion kit. This cable needs to be plugged into the cable that extends out from the hub. Then you will need to attach the orange-colored cable which connects the cadence sensor.

Experts advise to use good cable ties to tighten the lengths of the cable so they do not hinder your pedaling or get caught in the cranks or spokes. If you find blue-colored cables, then these are part of the optional brake sensor upgrade kit.

Different Types of E-Bike Conversion Kits

There are several different types of electric bike conversion kits available in the market today. For instance, you will find e-bike conversion kits that power your front or rear wheel or power the bike using cranks.

An alternate to this is the system that drives your wheels by pushing on the tire. However, this often causes tires to wear out sooner. You can also find e-bike conversion kits that power the e-bike through the bottom bracket. 

Normally, the battery of e-bike conversion kits can be fixed with a bolt on to the bicycle frame. You can also attach the battery to the handlebars and sometimes on to the rear rack.
