Compact 20" Fat Tire Build
We finished another e-bike build. Check out the video playlist for the action. This e-bike kit build is extremely exhilarating and satisfying. This time we installed a 20 inch fat tire rear hub ebike kit onto a youth/compact 20 inch fat tire bike. We bought the bike on Amazon. We installed a 1200 Watt EBikeling 20 inch fat tire rear hub ebike kit as well as a couple of comfort features.
The bike has a steel frame which helps keep the dropouts from snapping due to the torque of the hub motor. The durability of the steel frame provides the needed ruggedness when rivet nuts for the battery mount are installed. The maximum weight capacity of the Elecony 20 Inch Fat Tire Bike is 440lbs.
The 20 Inch Rear Hub eBike Kit
We selected the Ebikeling 20in fat tire rear hub Electric Bike Conversion Kit. It includes the battery, controller, S830 LCD Display, e-Brake Handles, Pedal Assist Sensor, and Thumb Throttle.
The dropout width of the Elecony 20 Inch fat tire bike required an 18mm long aluminum tubing custom cut axle spacer and 2x brake rotor adapter spacers to meet the dimensions of the frame and alignment of the brake caliper and rotor.
The Upgrades
The handlebars were extended to allow for a more upright and comfortable posture. To do so, we needed to add a stem, stem extender and BMX handle bars.
To accommodate the extra height in the handlebars, a new brake and shifter cable kit was installed. For a more finished look, cable sleeve was installed. A new gear shift was installed to replace the half-grip twist. We also added ergonomic grips for comfort.
To further enhance comfort during riding, we replaced the seat with an Oversized Bike Seat. Amazon has a ton of great options and something in everyone’s price range.
We were going to upgrade the brake system with Cable Hydraulic Disc Brakes, but after using the factory brakes, we decided not to get the new set.
A waterproof frame storage bag was chosen to house the controller and miscellaneous tools.
The pre-existing chain ring made it difficult to pedal at speeds higher than about 11.5mph. To counteract this, a larger 52T chainring was purchased and installed to provide more resistance to allow pedaling at higher speeds. The new chain ring is pictured below. Check out the video to see the installation.
